Unveiling the global reach of African anthrax research: A bibliometric study

Anthrax is a zoonotic bacterial disease caused by Bacillus anthracis. It poses significant threat to humans through contact with infected animals or their by-products. Concerns arise from its long-lasting spore viability and lethality, fuelling its biowarfare potential. Recent anthrax outbreaks across multiple African nations prompted this bibliometric study. The aim of the study was to assess the contributions of African countries, institutions, authors, research funding, and collaborations, while identifying research trends and gaps. We conducted an extensive bibliometric analysis of anthrax-related research publications in Africa from 1923 to 2023, utilizing the Scopus database and VOSviewer. The study covered 364 publications from 32 African countries, accumulating 5,636 citations at an average of 15.5 citations per article, with research articles comprising 88.5% of the corpus. The publication growth rate from 1923 to 2023 was modest at 8.3%, indicating gradual advancement. Notably, there was a significant surge in publications between 2011 and 2023, accounting for 73.1% of total publications. The African research contributions, were categorized into five thematic focuses: ecological dynamics and host interactions, human–livestock anthrax interface, molecular insights into bacterial activity and treatment strategies, collaborative approaches for zoonotic disease prevention, and antibody response and vaccination strategies. Leading institutional contributors included the University of Pretoria and the University of KwaZulu-Natal. Collaborations extended globally to 35 non-African countries, with significant involvement from the United States, United Kingdom, and Germany. Strong African partnerships, especially between Kenya, Nigeria, and South Africa, emerged. The top 10 cited papers explored diverse aspects, including disease impact on wildlife and innovative control strategies, underscoring the importance of multidisciplinary approaches. South Africa played a prominent role, contributing 95 publications and securing funding from various sources, including the National Research Foundation. Collaborations with global institutions highlighted its commitment. This study unveils the dynamic landscape of anthrax research in Africa, emphasizing the pivotal role of collaboration, multidisciplinary One Health approaches, and global partnerships in enhancing research outcomes. Ongoing research and practical solutions for human and animal health remain imperative.

Bayesian true prevalence estimation of brucellosis in sheep, goats, cattle and camels in southeast regions of Iran.

Brucellosis is worldwide one of the most prevalent zoonotic diseases with serious public health hazard affecting domestic livestock and causing economic losses. Objective of this study is to estimate the true prevalence of brucellosis in livestock, specifically cattle, sheep, goats and camels, using a novel Bayesian latent class model, adjusting for the imperfect sensitivity and specificity of the applied tests, where the second test was restricted only to first test-positive samples. Brucellosis seems more prevalent in goats and sheep, while the posterior medians and 95% probability intervals (95% PI) for the average true prevalence for sheep, goats, cattle and camels are 18% (4%-43%), 19% (7%-37%), 16% (5%-34%) and 18% (1%-48%) respectively. The study results indicate that brucellosis is highly endemic in Iran and crucial steps are needed to control and raise awareness about the high public health concern of the disease.

Assessing US Small Animal Veterinary Clinic Adaptations and Their Impacts on Workforce COVID-19 Preparedness and Response.

Veterinary personnel are an essential yet often underappreciated workforce, critical for zoonotic disease prevention and response efforts that impact human health. During the early COVID-19 pandemic, the veterinary workforce supported emergency responses by promoting zoonotic disease risk communication, sharing animal health expertise, and boosting laboratory surge capacity against SARS-CoV-2 in animals and people. However, small animal veterinary workers (SAVWs), similar to healthcare workers, faced organizational challenges in providing clinical care to family pets, including those susceptible to SARS-CoV-2. We analyzed a cross-sectional survey of 1,204 SAVWs in the United States to assess veterinary clinic adaptations and their associations with SAVWs' self-perceived readiness, willingness, and ability to respond to the COVID-19 pandemic as a workforce. SAVWs who worked fewer hours than before the pandemic (ready, OR 0.59; willing, OR 0.66; able, OR 0.52) or used personal protective equipment less frequently for protection in the clinic (ready, OR 0.69; willing, OR 0.69; able, OR 0.64) felt less ready, willing, and able to respond to COVID-19. SAVWs working remotely felt less ready (OR 0.46) but not less willing or able to respond to COVID-19. Lastly, SAVWs with dependents felt less ready (OR 0.67) and able (OR 0.49) to respond to COVID-19 than SAVWs without dependents. Our findings highlight the importance of proactively managing work schedules, having access to personal protective equipment, and addressing caregiving concerns to enhance SAVW preparedness and response outcomes. SAVWs are knowledgeable, motivated personnel who should be integrated into local public health emergency preparedness and response plans, supporting a One Health framework that unites multidisciplinary teams to respond to future zoonotic disease threats.

Zoonotic disease classification in wildlife: a theoretical framework for researchers

Abstract Classification systems are useful tools for aggregating diseases to study them in more detail. The most widespread system for the classification of human diseases is the International Classification of Diseases (ICD); however, the ICD was designed for use in health care and fails to capture many details of zoonotic diseases as a result. We propose a framework for zoonotic disease classification which combines four known classification types (pathogen type, life cycle, transmission direction and ecosystem) into one systematic method. We chose to focus on four specific aspects to provide as broad an overview as possible of zoonoses, in order to inform the risk of transmission to humans. This framework can be applied to the zoonoses occurring in any non‐human animal species and supports the generation of systematically collected empirical data that are useful for monitoring the spatio‐temporal dynamics of zoonoses. To demonstrate the utility of our framework, we focus on six deer species that are widespread in Eurasia: red deer Cervus elaphus, roe deer Capreolus capreolus, fallow deer Dama dama, sika deer Cervus nippon, Reeves's muntjac Muntiacus reevesi and Chinese water deer Hydropotes inermis. We examined the worldwide occurrence and prevalence of zoonoses in these species through a scoping review of the literature. Altogether, 996 records of zoonotic diseases in the six wild deer species, from 431 peer‐reviewed papers, and 120 zoonotic pathogens were found. Within deer populations, the most prevalent zoonoses were bacterial, while the most prevalent life cycles were metazoonoses. We also found that the most prevalent pathogens in deer were those with hosts capable of occupying sylvatic, peridomestic and domestic ecosystems. Baseline data generated using our framework method can provide important starting points for making projections of human disease risk, assisting wildlife managers and policy‐makers in making wildlife management decisions, and assisting experts in the development of disease‐monitoring and management plans.

Microbial assessment of poultry farm biosecurity. Proceeding of The First International Avian Influenza Summit, University of Arkansas- October 16-17, 2023”

Biosecurity may be defined as protection from pathogens or disease. This may include the separation of the flock from living vectors or inanimate objects called fomites. While prevention of host-specific and zoonotic diseases is important, the commercial poultry industry is already preoccupied with the challenges of day-to-day operations. The purpose of this project was to illustrate how surfaces that may seem clean are heavily contaminated with microorganisms that may be responsible for human and avian diseases. We also evaluated three common intervention strategies, including disposable boot covers, foot baths, and tire disinfection. Poultry environmental samples were collected at the Texas A\&M University Poultry Science Research Center, including fan shrouds, side air inlets, cool cell reservoirs, truck tires, truck floor mats, doorknobs, controller panels, a bioaerosol air sampler, and an impactor air sampler. A total of 30 samples were collected per sample type, which was homogenized, serially diluted, and spread plated onto agar media to culture total aerobes, Staphylococci, and coliform bacteria. 6.6 log10 colony-forming units cfu/cm2 of aerobic bacteria were found at the greatest concentration, followed by Staphylococci (5.6 log10 colony-forming units cfu/cm2) and coliforms (2 log10 colony-forming units cfu/cm2). This pattern was observed in most of the samples. Boot covers, foot baths, and tire disinfection were tested for efficacy. While disposable boot covers significantly reduced the number of aerobes, Staphylococci, and coliforms, as many as 300 microorganisms per cm2 still made it through to the inner boot cover. Disinfectants are commonly misused due to not properly clearing the surface prior to application or allowing the proper contact time. We found that while disinfection significantly reduced these indicator organisms, that reductions were only 10 to 100-fold, leaving many viable bacteria behind. Increased contact time from 3 seconds to 10 minutes resulted in significant reductions of aerobes and Staphylococcus. The tire wash data mirrored our foot bath data. Data was shared from previous laboratory and field trials. Less than 1% sterile poultry litter significantly reduced disinfectant efficacy across four product categories. Extended storage time of 30 weeks reduced product efficacy as well. We shared electron micrographs to illustrate how visually clean and smooth surfaces provide many hiding places for microbes, reducing disinfectant efficacy. While risk can never be reduced to zero, it may be reduced and controlled with good management practices. Cleaning and disinfection should follow a five-step process of dry cleaning, soap wash, rinse, drying, and finally disinfection. Labels should be read closely so that the product is used safely and effectively. While there are many viable products on the market, disinfecting a clean surface and following recommendations for contact time are very important to get the best results. Following best management practices such as reducing pest (insect/rodent) harborage and following your integrated pest management program will help reduce risk significantly.

India’s sustaining challenges to combat rabies elimination: a comprehensive review

Rabies is one of the fatal zoonotic diseases wreaking havoc on humanity since antiquity. India continues to suffer the greatest rabies burden of any country, both in terms of annual human deaths and disability-adjusted life years. While modern rabies management emphasizes the importance of achieving zoonotic disease control and prevention through a One Health approach, the disease remains challenging as its persistence is invariably multifaceted. Therefore, it is imperative to examine the enduring reasons for the increasing incidence of rabies in India. Between 2012- 2022, a systematic search of scientific publications, popular search engines like Google, as well as in the grey literature regarding rabies was carried out. Since rabies elimination boils down to addressing the reasons, it is first seen related to the large and unvaccinated stray dog population, where 97% of cases are by dog bites. A second finding is that many bite victims resorted to indigenous treatment practices due to insufficient awareness and knowledge about the disease. Incomplete treatment practices also led to some deaths, especially because rabies vaccines are not affordable or accessible to poverty-stricken populations. Rarely, vaccine failures were caused by a lack of vaccine potency, a wound type, or ineffective administration methods. Even with all these data incorporated, there was no information on prevalence/incidence estimates of dog bites in recent years through national data. Therefore, without intensified surveillance, sustained political commitment, enormous mobilization of resources, and rabies education, the epidemic waves of this fatal disease will continue in India.

One Health Approach to Leptospirosis: Dogs as Environmental Sentinels for Identification and Monitoring of Human Risk Areas in Southern Brazil.

Leptospirosis has been a neglected, widespread and reemerging zoonotic disease of global importance. The One Health holistic approach combining human, animal and environmental health has been important for control and prevention of zoonotic disease. An urban municipality in Southern Brazil with a high prevalence of leptospirosis was selected by convenience, with asymptomatic human and canine individuals serologically tested using MAT against 30 Leptospira spp. serovars. Epidemiological questionnaires were assessed along with the historical national database, with associated risk factors to dog and human seropositivity analyzed using multiple logistic regression. The spatial distribution of retrospective human leptospirosis cases was analyzed using a Kernel map and overlapped dog seropositivity and historical flooding areas, demonstrating that domestic and asymptomatic dogs may be important environmental sentinels for leptospirosis in such urban areas, even in the absence of human seropositivity and low canine seropositivity. Associated risk factors for leptospirosis in dogs and humans according to multiple regression included healthy dogs (p = 0.02, odds ratio-OR = 0.17, confidence interval of 95%CI 0.03-0.71) with indoor access (p = 0.059, OR = 5.12, 95%CI 1.10-37.7) and human males (p = 0.042, OR = 2.44, 95%CI 1.08-6.11) with presenting calf pain (p = 0.005, OR = 3.14, 95%CI 1.46-7. 14), jaundice (p < 0.001, OR = 4.61, 95%CI 2.11-10.10) and renal failure (p = 0.008, OR = 4.49, 95%CI 1.49-13.76). The greater the rain precipitation (above 3 mm of average annual precipitation), the higher the number of leptospirosis cases in humans. In conclusion, dog active serosurvey and rain precipitation should be systematically reported and plotted altogether as a basis for the early detection and monitoring of human risk areas. Such findings may serve as a basis for public health policies in Brazil and other endemic countries worldwide.

Unraveling the Role of the Zinc-Dependent Metalloproteinase/HTH-Xre Toxin/Antitoxin (TA) System of Brucella abortus in the Oxidative Stress Response: Insights into the Stress Response and Virulence.

Toxin/antitoxin (TA) systems have been scarcely studied in Brucella abortus, the causative agent of brucellosis, which is one of the most prevalent zoonotic diseases worldwide. In this study, the roles of a putative type II TA system composed by a Zinc-dependent metalloproteinase (ZnMP) and a transcriptional regulator HTH-Xre were evaluated. The deletion of the open reading frame (ORF) BAB1_0270, coding for ZnMP, used to produce a mutant strain, allowed us to evaluate the survival and gene expression of B. abortus 2308 under oxidative conditions. Our results showed that the B. abortus mutant strain exhibited a significantly reduced capacity to survive under hydrogen peroxide-induced oxidative stress. Furthermore, this mutant strain showed a decreased expression of genes coding for catalase (katE), alkyl hydroperoxide reductase (ahpC) and transcriptional regulators (oxyR and oxyR-like), as well as genes involved in the general stress response, phyR and rpoE1, when compared to the wild-type strain. These findings suggest that this type II ZnMP/HTH-Xre TA system is required by B. abortus to resist oxidative stress. Additionally, previous evidence has demonstrated that this ZnMP also participates in the acidic stress resistance and virulence of B. abortus 2308. Therefore, we propose a hypothetical regulatory function for this ZnMP/HTH-Xre TA system, providing insight into the stress response and its potential roles in the pathogenesis of B. abortus.

Global, regional, and country-level cost of leptospirosis due to loss of productivity in humans.

Leptospirosis, a prevalent zoonotic disease with One Health priority and a disease of poverty, lacks global economic burden estimates. This study aims to determine the global, regional, and country-level cost of leptospirosis due to loss of productivity. The cost of leptospirosis due to loss of productivity (referred to as productivity cost hereafter) was estimated by converting the disability-adjusted life years (DALYs) lost due to leptospirosis to a monetary value using the per capita gross domestic product (GDP). The country-specific DALYs lost were obtained from the global burden of leptospirosis study published previously. Non-health GDP per capita (GDP- per capita health expenditure) was used for the cost conversion of DALYs. Country-specific GDP and health expenditure data were obtained from the World Bank data repositories. Estimates were done using both nominal and international dollars. The estimated global productivity cost of leptospirosis in 2019 was Int$ 29.3 billion, with low and high estimates ranging from Int$ 11.6 billion to 52.3 billion. China (Int$ 4.8 billion), India (Int$ 4.6 billion), Indonesia (Int$ 2.8 billion), Sri Lanka (Int$ 2.1 billion), and the United States (Int$ 1.3 billion) had the highest productivity cost due to leptospirosis. Eight out of 10 countries with the highest burden were in the Asia-Pacific region. In addition, lower-middle-income countries had an annual productivity cost of Int$ 13.8 billion, indicating that the disease is poverty-related. Although significant, the cost estimate due to loss of productivity is merely a fraction of the overall economic burden of this disease, which also includes other direct, indirect, and intangible costs. The existing partial estimates of the different components of economic cost suggest a profound economic burden that demands the inclusion of leptospirosis in the global health agenda for comprehensive disease control and prevention efforts, including vaccine development.

A DNA vaccine (EG95-PT1/2/3-IL2) encoding multi-epitope antigen and IL-2 provokes efficient and long-term immunity to echinococcosis

Echinococcosis is a highly prevalent global zoonosis, and vaccines are required. The commercial vaccine based on a protein-based subunit (EG95), however, is limited by its insufficient cellular immunity, a short protection period, and limited prevention against novel mutant strains. Herein, we applied bioinformatics to develop a DNA vaccine (pEG95-IL2) expressing both multi-epitope-based antigens (EG95-PT1/2/3) and an IL-2 adjuvant to regulate T cell differentiation and memory cell response. EG95-PT1/2/3 was screened with hierarchical structure prediction from the epitope conformation of B cells with high confidence across various species to guarantee immunogenicity. Importantly, cationic arginine-rich lipid nanoparticles (RNP) were utilized as a delivery vehicle to form lipoplexes that had a transfection efficiency of nearly two orders of magnitude greater than that of commercial reagents (Lipofectamine 2000 and polyethyleneimine) with both immune and nonimmune cells (DC2.4 and L929 cells, respectively). RNP/pEG95-IL2 lipoplexes displayed a robust and long-term antigen expression, as well as adjuvant effects during the immunization. Consequently, intramuscular injection of RNP/pEG95-IL2 elicited similar humoral immune responses and significantly greater cellular responses in mice when compared with those of the commercial vaccine. In addition, the inoculation protocol of RNP/pEG95-IL2 with sequential booster further strengthens cellular immunity in comparison with the homologous booster. Those findings provide a promising strategy for improving plasmid vaccine efficacy.

Toxoplasma gondii Seroprevalence and Trends in Women Presenting for Toxoplasma Screening in South-West Romania.

Toxoplasmosis, caused by the obligate intracellular protozoan parasite Toxoplasma gondii (T. gondii), is a globally prevalent zoonotic disease with potentially severe implications for immunocompromised individuals, pregnant women, and their fetuses/children. This study examined the prevalence of anti-T. gondii IgM and IgG antibodies in two groups of childbearing age women, including 653 participants in Group 1 (2013-2016) and 3221 participants in Group 2 (2019-2022). Our results revealed a decrease in the overall positivity rate of anti-T. gondii IgM antibodies from 2.32% to 1.06%, suggesting improved public health interventions over time. However, there were variations among different age groups and between rural and urban environments, with a significant decrease in urban areas across all age groups from Group 1 to Group 2. Regarding anti-T. gondii IgG antibodies, we did not observe a significant change in the seropositivity rate between the two groups. In the rural population with an age group over 35 years, we observed the highest positivity rate in Group 2. This study provided information on the risk factors and burden of toxoplasmosis in women of childbearing age with data that can be valuable to public health policies and the planning of healthcare measures for effective toxoplasmosis management.

Advances in CRISPR/Cas-Based Strategies on Zoonosis

Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated (Cas) has emerged as the predominant technique for gene editing technique due to its high efficiency and low cost. In the area of zoonosis, CRISPR/Cas is also widely used in different research areas. This paper reviewed the principles of CRISPR/Cas technique and its applications in zoonosis. Moreover, we analyze the shortcomings and weaknesses that currently limit its use, highlight its direction for improvement, and foresee its application prospects in the prevention and treatment of zoonosis. For the purpose of preventing and controlling zoonosis, we need to develop diagnostic method with high sensitivity and specificity, highly protective vaccines, and also better understanding of the pathogenesis. Our review aimed to promote the application and improvement of CRISPR/Cas technique in the above-mentioned areas, and provide brief and comprehensive references for CRISPR/Cas-based research. Through reviewing the advances in CRISPR/Cas-based strategies on zoonosis, we believe that CRISPR/Cas technique will provide more powerful assistance for the prevention and control of zoonosis.

Domesticated Cats as a Source of Environmental Contamination with Toxocara cati and Other Soil-Transmitted Helmminth Eggs in Urban Area, Manila-Philiphines

Toxocariasis and soil-transmitted helminthiases are the most prevalent parasitic zoonoses affecting humans and animals that cause environmental contamination. Toxocara and other soil-transmitted helminth eggs in animal feces are the primary sources of soil-transmitted helminthiases transmission in the environment particularly in urban areas. These parasite eggs constitute a source of infection for both definitive and paratenic hosts. Avian and rodents, that can be paratenic hosts of these parasites, are a significant source of food for cats in urban settings. Stray cats and dogs also consume leftover food or receive frequent feedings from locals that increases the chance of acquiring soil-transmitted helminth infections. Despite the risks that these soil-transmitted helminths have, studies and information regarding their zoonotic potential is very limited to date. This study aimed to determine the relationship between cat feces and the environmental contamination of residential soils with Toxocara cati and other soil-transmitted helminth eggs. A total of 50 samples were collected in selected urban residences in Malate, Manila. Stool samples were processed using Formol-Ether Concentration Technique while optimized sugar flotation technique was used for the soil samples then both were subjected to microscopy. The overall infection rate was 76% and the contamination rate was 52%. Toxocara cati was the most prevalent zoonotic parasite identified in 48% of stool and 44% of soil samples followed by Ascaris spp. with 32% in stools and 16% in soil samples. Trichuris spp. with 24% and hookworm with 16% were also detected in stool samples but were absent in soil samples. The presence of Toxocara cati and Ascaris spp. eggs in feces and their environmental contamination might be accounted to their durable and highly resistant eggs as well as the as the Philippines as a tropical country which may induce optimal conditions for Toxocara spp. and other soil-transmitted helminth eggs’ development and survival.&#x0D;

One Health in Turkana County, Kenya: Applications and Lessons Learned

Abstract Pastoralists contribute to social, environmental, and economic well-being in the drylands of Northern Kenya. Pastoralism is also their way of life and how they manage their livelihoods. However, the marginalization of these communities, including the lack of basic infrastructure and services, compounded by the increasing threat of infectious disease and climate change, has led to the loss of livelihoods and poor health. One Health service delivery can improve pastoralists’ health and livelihoods. This case examines the development of the One Health policy in Turkana County, Kenya. The Turkana One Health Strategy (TOHS) is undergoing final approval. We discuss the contributions of the One Health Strategic Plan for the Prevention and Control of Zoonotic Diseases in Kenya, the One Health framework for integrated service delivery, and the Kimormor outreach model to this plan. We also describe recent One Health activities in Turkana and identify the benefits and limitations of each. One Health service delivery improved access to human health, animal health, and administrative services in rural, hard-to-reach areas in Turkana. Empowering communities to lead and take ownership of One Health activities is critical for implementation. One Health service delivery has some limitations, such as being resource and time intensive and being a relatively new concept in healthcare. Turkana County provides a valuable example of how One Health policy turns into practice through multilevel coordination structures, the support of public and private partners, and transdisciplinary research. It can act as a model for implementing One Health activities in Northern Kenya and other countries. Information © The Authors 2023

Pericia legal y forense en el laboratorio veterinario: Revisión

Veterinary laboratories have technologies necessary for the processing of analyses, examinations and techniques in the scientific investigation of legal and forensic expertise. This paper aims to survey and critically evaluate areas of knowledge that can be used in forensic science in the veterinary laboratory. In veterinary forensic medicine, the issues of liability for negligence, incompetence, malpractice or imprudence, both in the administrative and in the civil or criminal spheres, increase every day. The assistance provided by forensic veterinary medicine is not limited to the knowledge in legal and forensic expertise applied to living or dead animals - it also extends to the field of laboratory analysis. The investigation of a crime scene is the meeting point between science and the law, and veterinary laboratories are fundamental to meet much of the analyses, examinations, and techniques. Among the main fields of laboratory activities are serodiagnostics, toxicology serodiagnosis, toxicology, biochemistry, microbiology, pathology, necropsy and others that have fundamental importance in the elaboration of expert evidence. In these laboratories, professionals can perform analyses that contribute to the study, prevention, diagnosis and treatment of animal health problems, environmental health and zoonoses applied to forensic practice. The quality assurance of the products and services of these laboratories, combined with quality management, minimizes errors, ensures credibility, biosecurity and reliability of results. The Veterinarian is designated as the Technical Manager (TM) to assume responsibility as manager of all activities inherent to the laboratories. In this context, the veterinary laboratories deserve singular attention in the field of the analyses, exams and techniques necessary for legal and forensic investigations, and elaboration of technical reports that assist justice.

On-Site Inspection Form in Veterinary Cases: The Parma Veterinary Form.

The on-site inspection of the scene of an animal cadaver is crucial for a correct interpretation of the autopsy results, to determine the manner, method, and cause of death. This information plays a crucial role in the control of public health including the prevention of zoonoses. It is also fundamental for the recognition and the contrast of crimes against animals and to animal abuse phenomena, considered an alert sign of an anti-social or violent behavior of humans. Today the best veterinary procedure requires an accurate collection of the evidence at the scene that can be then handed to experts belonging to other forensic disciplines for further evaluation and data interpretation. In this paper authors suggest a form aiming to facilitate either the on-site and the autopsy activities, as a guarantee of the quality of the forensic process starting from the discovery scene up to the reconstruction of the case. Essential is training of non-medical personnel who often represent the first responder to be present on the scene. The form is inspired by the interdisciplinary form developed by the European Council of Legal Medicine and represents an initial tool to stimulate a multidisciplinary activity in close synergy with other forensic experts.

The community engagement course and action network: strengthening community and academic research partnerships to advance health equity.

Historically Black Colleges and Universities and Minority Serving Institutions are uniquely positioned to implement community-campus research partnerships based on a history of service, the pursuit of community trustworthiness and student demographics often similar to surrounding marginalized communities. The Morehouse School of Medicine Prevention Research Center collaborates with members of Historically Black Colleges and Universities, Minority Serving Institutes, and community organizations on the Community Engaged Course and Action Network. This network is the first of its kind and aims to strengthen members' ability to implement Community-Based Participatory Research (CBPR) principles and partnerships. Projects address public health priorities including mental health among communities of color, zoonotic disease prevention, and urban food deserts. To assess the effectiveness of the network, a Participatory Evaluation framework was implemented to conduct process evaluation which included review of partnership structures, operations, project implementation processes, and preliminary outcomes of the research collaborations. A focus group of Community Engagement Course and Action Network members (community and academic) was also conducted to identify benefits and challenges of the network with emphasis on key areas for improvement to further enhance the relationships between partners and to facilitate their subsequent community-campus research. Network improvements were tied to themes strengthening community-academic partnerships including sharing and fellowship, coalition building and collaboration, and greater connections and awareness of community needs through their current community-academic partnerships. The need to conduct ongoing evaluation during and after implementation, for determining the early adoption of CBPR approaches was also identified. Evaluation of the network's processes, infrastructure, and operation provides early lessons learned to strengthen the network. Ongoing assessment is also essential for ensuring continuous quality improvement across partnerships such as determining CBPR fidelity, assessing partnership synergy, and dynamics, and for quality improvement of research protocol. The implications and potential for advancing implementation science through this and similar networks are great towards advancing leadership in modeling how foundations in community service can advance to CBPR partnership formation and ultimately, health equity approaches, that are local defined and assessed.

Prevention of Zoonotic diseases: Knowledge, attitude and practices of arable crop farmers in Osun state

Prevention of Zoonotic diseases: Knowledge, attitude and practices of arable crop farmers in Osun state

Continuous surveillance and viral discovery in animals and humans are a core component of a one-health approach to address recent viral reverse zoonoses.

Contemporary human and animal viruses have a broad or narrow host range-those with a broad host range are potentially transmitted from animals to humans (ie, zoonosis) or humans to animals (ie, reverse zoonosis). This Currents in One Health article reviews the recent reverse zoonoses involving Coronaviridae, Poxviridae, arboviruses, and, for nonhuman primate species, the human respiratory viruses. The prevention and control of reverse zoonoses are also reviewed. Coronaviruses continue to emerge as new zoonotic agents, including a canine coronavirus, CCoV-HuPn-2018, circulating in people at low levels, and a pangolin coronavirus, MjHKU4r-CoV-1, circulating in Malayan pangolins. Moreover, the risk for SARS-CoV-2 variants to mutate in animal reservoirs and reinfect humans is ongoing. In the case of mpox, the risk of reverse zoonosis is low and there are vaccines for use in humans at risk. The situation with arboviruses is as varied as the number of human arboviruses, and only yellow fever virus and dengue virus have licensed vaccines in the Americas. As for reverse zoonoses in endangered species, solutions require changing human behavior and policies at all levels impacting wildlife. Overall, continuous surveillance and viral discovery in humans and animals remain core components of a one-health approach to reduce and, where possible, eliminate zoonotic and reverse zoonotic diseases. Viral zoonosis and viral reverse zoonosis focusing on recent influenza A virus disease events in humans and other species are the subjects of the companion Currents in One Health by Kibenge, AJVR, June 2023.
