Mid-level healthcare workers knowledge on non-communicable diseases in Tanzania: a district-level pre-and post-training assessment

IntroductionOver the past two decades, Tanzania’s burden of non-communicable diseases has grown disproportionately, but limited resources are still prioritized. A trained human resource for health is urgently needed to combat these diseases. However, continuous medical education for NCDs is scarce. This paper reports on the mid-level healthcare workers knowledge on NCDs. We assessed the knowledge to measure the effectiveness of the training conducted during the initiation of a Package for Essential Management of Severe NCDs (PEN Plus) in rural district hospitals in Tanzania.MethodsThe training was given to 48 healthcare employees from Dodoma Region’s Kondoa Town Council District Hospital. For a total of five (5) days, a fundamental course on NCDs featured in-depth interactive lectures and practical workshops. Physicians from Tanzania’s higher education institutions, tertiary university hospitals, research institutes, and medical organizations served as trainers. Before and after the training, a knowledge assessment comprising 28 questions was administered. Descriptive data analysis to describe the characteristics of the specific knowledge on physiology, diagnosis and therapy of diabetes mellitus, rheumatic fever, heart disease, and sickle cell disease was done using Stata version 17 (STATA Corp Inc., TX, USA).ResultsComplete assessment data for 42 out of the 48 participants was available. Six participants did not complete the training and the assessment. The mean age of participants was 36.9 years, and slightly above half (52%) were above 35 years. Two-thirds (61.9%) were female, and about half (45%) were nurses. The majority had the experience of working for more than 5 years, and the average was 9.4 years (+/- 8.4 years). Overall, the trainees’ average scores improved after the training (12.79 vs. 16.05, p < 0.0001) out of 28 possible scores. Specifically, trainees’ average scores were better in treatment than in diagnosis, except for sickle cell disease (1.26 vs. 1.83). Most were not able to diagnose rheumatic heart disease (47.6% able) compared to diabetes mellitus (54.8% able) or sickle cell disease (64.3% able) at baseline. The proportion of trainees with adequate knowledge of the treatment of sickle cell disease and diabetes mellitus was 35% and 38.1%, respectively, and there was a non-statistical difference after training. Those working for less than 5 years had a higher proportion of adequate knowledge (30.8%) compared to their more experienced colleagues (6.9%). After the training, participants’ knowledge of NCDs increased by three times (i.e., aPR 3, 95% CI = 1.1, 1.5, and 6.0).Conclusion and recommendationsPEN Plus training improved the knowledge of healthcare workers at Kondoa Town Council District Hospital. Training is especially needed among nurses and those with a longer duration of work. Continuing education for human resources for health on the management of NCDs is highly recommended in this setting.

Perceptions on Medical Professionalism Among Future Healthcare Professionals: A Mixed Method Study.

Background Accreditation councils across the world constantly examine policies and practices in professionalism in their medical curriculum. The National Medical Commission (NMC) in India has recognized the pressing need to reform and include professionalism in its undergraduate curriculum. Objectives The objective of this study was to explore the perspectives of medical and nursing students on professional behavior, suitable teaching-learning methods, and assessment strategies for curriculum integration. Methodology The study utilized a concurrent triangulation mixed method design, collecting both qualitative and quantitative data simultaneously to gain a comprehensive understanding of medical and nursing students' perceptions of professionalism. It included 83 final-year undergraduate medical students and 42 final-year undergraduate nursing students. The approval of the Institutional Review Board of Meenakshi Medical College Hospital & Research Institute was obtained. A semi-structured questionnaire consisting of demographic characteristicsand opinions regarding academic professional behavior, teaching-learning, and evaluation of professionalism was used. Perceptions regarding the meaning of professionalism, behavior of professionalism to be emphasized in teaching, and pressing challenges of professionalism were explored. Students were also asked to rank the best behavior associated with professionalism. Frequency and percentages were used for descriptive statistics. Means and standard deviations were calculated for continuous variables. An unpaired t-test was used to determine a statistically significant difference between the means in the two groups. The quantitative data was analyzed with R programming and content analysis was performed for the qualitative data using ATLAS.ti qualitative data analysis software. Results Unexplained/unauthorized absence from academic activities (2.39 ± 1.553), not following the timeline (2.41 ± 1.560), making fun of patients and peers (2.16 ± 1.619), cheating in the exams (2.37 ± 1.651), and inebriation (2.39 ± 1.666) were unacceptable behaviors by undergraduate medical students compared with nursing students. Clinical experience (1.54 ± 0.857) and role models (1.74 ± 0.935) were the highly acceptable methods of teaching professionalism and interprofessional interactions (1.58 ± 0.650) and awards (1.98 ± 1.100) were the most common suggestions to improve the course curriculum by both groups. Community/field activity (1.78 ± 0.860) and clinical examination (1.89 ±1.123) were the most preferred methods of evaluation of professionalism. According to the students, dedication, honesty, respect, and self-improvement were identified as the best behaviors associated with professionalism. Conclusions The study revealed that students had a wide range of perspectives about professionalism. Different unprofessional acts were acceptable to students. The causes of these perspectives need to be explored and resolved to promote professionalism. Students identified the need for strong positive role models and frequent clinical experiences, along with improved interprofessional interactions and awards to improve teaching and learning professionalism. Community/field activity was the preferred assessment method proposed by the students. Medical institutions must promote these components in curriculum, faculty development, and clinical settings to foster the development of professionalism among students.

How Can Small and Medium-Sized Manufacturing Enterprises Improve Green Innovation Performance through Innovation Ecosystems?

Under the fierce business competition and sustainable development pressure, the pattern of enterprise innovation has gradually changed from independent innovation to cooperative innovation. As a collection of multi-type innovation actors, the innovation ecosystem provides opportunities and platforms for cooperative innovation among government–industry–university–research institutions. While the present studies on innovation ecosystems are mostly from the perspective of the system level, few studies pay attention to the innovation mechanism of small and medium-sized manufacturing enterprises (SMMEs) in the innovation ecosystem. Therefore, this study takes SMMEs embedded in innovation ecosystems as research objects and explores the factors affecting green innovation. We constructed a theoretical model to explain the effect of innovation eco-embeddedness on green innovation performance based on ecosystem theory and network embeddedness theory; we then collected 363 samples of SMMEs in China through surveys and further tested the data empirically. The results show that the innovation eco-embeddedness (IEE) of SMMEs has a positive effect on their green innovation performance (GIP), and their green value co-creation practices (GVCCPs) partially mediate the relationship between IEE and GIP. Moreover, ecological norms (ENs) in the innovation ecosystem not only positively moderate the impact of IEE on GVCCPs but also positively moderate the mediating role of GVCCPs. This study enriches the relevant research on innovation ecosystems from the perspective of non-core enterprises and provides a theoretical basis and practical reference for SMMEs to implement green innovation practices and realize growth through innovation ecosystems.

Effectiveness of Om chanting on perceived stress, negative affectivity, and social inhibition in individuals with pre-hypertension

Background: Akara, Ukara, Makara (OUM) chanting regulates emotions and removes negative emotions by inactivating the processing in the amygdala. At the same time, the prefrontal complex was inhibited followed by chanting OUM. Further, there was an increase in the oxygenation levels followed by chanting OUM. Hence, OUM chanting has multiple benefits and offers improvement in the quality of life. Though there are multiple benefits followed by chanting OUM, the scientific evidence for the same is comparatively less. Hence, there is a need for more studies in this area. Aims and Objectives: The present study aimed to find out the variations in the perceived stress, negative affectivity, and social inhibition in pre-hypertensive individuals and also to observe the effectiveness of Om chanting on perceived stress, negative affectivity, and social inhibition in pre-hypertensive individuals. Materials and Methods: The present study was conducted at the St Peter’s Medical College Hospital and Research Institute, Hosur, Tamil Nadu, India. A total of 50 young adults with pre-hypertension were recruited in the study after obtaining written informed consent. Age- and gender-matched 50 healthy participants were recruited after obtaining the voluntary, informed consent. Diamond digital sphygmomanometer was used to record the blood pressure. All the parameters were recorded at 9 am for the convenience of the participants and also to avoid diurnal variation. The perceived stress scale was used to assess the stress levels. Negative affectivity and social inhibition were recorded using a type D (DS-14) questionnaire. Cases practiced the OUM chanting for 6 weeks after they were trained by an expert yoga therapist. Results: Perceived stress scores were significantly decreased followed by the OUM chanting. There was a significant decrease in the scores of negative affectivity of cases after the intervention when compared with control group participants. There was a significant decrease in the scores of social inhibition of cases after the intervention when compared with control group participants. Conclusion: Perceived stress, negative affectivity, and social inhibition were significantly higher in the pre-hypertensive individuals. The study results provide further evidence that practicing OUM chanting causes stress relief and also decreases the negative emotions that is negative affectivity and social inhibition in pre-hypertensive individuals.

A Retrospective Study of the Relationship Between Typhoid and Vestibular Disorders- A Case Series

Background: Typhoid fever is caused by Salmonella enterica serovar Typhi (Salmonella Typhi). faecal-oral is the main route of transmission by contaminated water or food. Over the last few years, the classic presentation of typhoid fever has varied, and the cases with atypical presentation are increasing. In this study we are presenting a retrospective evaluation of patients presenting with giddiness post history of typhoid, to correlate a link between vestibular disorders and typhoid. Aims and Objectives: To retrospectively study the relationship between typhoid and vestibular disorders. Materials and Methods: This is a retrospective hospital-based case series conducted in vertigo clinic in The Department of ENT at SGT Medical College Hospital and Research Institute, Budhera, Gurugram. Five patients who gave positive history of typhoid, their case files were retrospectively evaluated. All the patients were made to undergo routine ENT, vertigo, and audiological evaluation. Results: Total of 5 patients presented to vertigo clinic at SGT hospital with complains of giddiness, all of them gave a history of typhoid in the past few weeks. Majority of patients presented with giddiness within four weeks after history of typhoid infection. Patients developed symptoms of giddiness, nausea, and vomiting. Out of 5 patients,4 were females and one male. Two patients were in the age group of 30-40 years. Two patients were in paediatric age group. On examination, Dix Hallpike test was positive in 3 patients. Patients were treated with vestibular sedatives and corrective manoeuvre like Epley’s. Pure tone audiometry, MRI brain and lab parameters were all normal in all the five patients. Conclusion: Endotoxins of the typhoid bacillus are capable of producing cochleovestibular lesions but only a few isolated reports suggest the same. Since very few literatures has been discussed on the possible correlation between vestibular disorders and typhoid, clinicians should be aware of atypical presentations of typhoid is to avoid any delay in diagnosis and prompt treatment. Therefore, there is a strong need to analyse and study the corelation between typhoid fever and vestibular disorders.

Types of common R&D partners and knowledge leakage to rivals: The role of IP litigation reputation

We argue that knowledge leakage may occur between rival firms through indirect ties, i.e., if rivals collaborate on R&D with a common partner, but that firms with an aggressive reputation for IP litigation may be able to restrict such knowledge spillovers. We argue that knowledge leakage is more prominent, and litigation reputation is less powerful, when the common partner is a university or public research institution adhering to the open science paradigm, compared with when the common partner is another (non-rival) firm. Patent similarity analysis among dyads of leading pharmaceutical firms provides support for these hypotheses.

Community engagement in genetics and genomics research: a qualitative study of the perspectives of genetics and genomics researchers in Uganda

BackgroundGenerally, there is unanimity about the value of community engagement in health-related research. There is also a growing tendency to view genetics and genomics research (GGR) as a special category of research, the conduct of which including community engagement (CE) as needing additional caution. One of the motivations of this study was to establish how differently if at all, we should think about CE in GGR.AimTo assess the perspectives of genetics and genomics researchers in Uganda on CE in GGR.MethodA cross-sectional qualitative study was conducted at Makerere University and Uganda Virus Research Institute. Twenty-five individuals participated, the majority being male (sixteen). Participants included nineteen genetics and genomics researchers (researchers and research coordinators), two CE officers, three nurses and one nursing counsellor. Data were collected using in-depth interviews and analyzed in a thematic manner using NVivo version 12 Plus.Study findingsThirteen of the respondents had conducted CE in their GGR in either a geographical and disease-specific community. Some respondents said CE principles are the same and there is no need for special consideration for CE in GGR. Others gave ethical issues in GGR that require special consideration for CE in such research and these were categorized into six themes: GGR is new to communities, Difficulty in communicating GGR by the researchers, Genes are shared in communities, Cultural sensitivities against GGR, Community attitude toward GGR, Some GGR studies take long to end, and Negotiation of research benefits. Special considerations for CE when conducting GGR were suggested and categorized into seven themes: creating awareness of GGR in communities, obtaining both community acceptance and individual consent, CE team composition, involve communities in solving GGR challenges, prolong CE in some GGR, develop guidelines for CE in GGR, and legal considerations on GGR.ConclusionGGR was characterized by special issues that require special CE considerations for such research.

Effectiveness of Hamstring Release and Neural Mobilisation in Improving Walking Capability and Physical Activity Associated with Intermittent Neurogenic Claudication in Patients with Lumbar Spinal Stenosis: A Quasi-experimental Study

Introduction: In India, one of the most prevalent spinal pathologies is Lumbar Spinal Stenosis (LSS). It is characterised by the compression of neural structures in the spinal canal, resulting in symptoms such as neurogenic claudication, lower extremity radiculopathy, and gait impairment. Treatment involves various therapeutic modalities, with present study focusing on an integrated exercise method. Aim: To evaluate the potential efficacy of hamstring release and neural mobilisation in LSS patients. Materials and Methods: This quasi-experimental study was conducted at SGT Medical College Hospital and Research Institute, Gurugram, Haryana, India from September 2021 to May 2022. Total of 30 patients diagnosed with LSS were divided into two groups based on inclusion criteria: group A (experimental) and group B (control). Pain, neural flexibility, walking capacity, disability, and physical activity were assessed at baseline and after the 3rd week of the intervention. Treatment sessions were administered for 30 minutes per day, three times per week (on alternate days), for a duration of three weeks in both groups. Data analysis was done using the Windows version of Statistical Package for Social Sciences version 26.0 (SPSS, Chicago, IL, USA). The paired t-test was used to compare mean data within each group before and after the intervention. The Independent t-test formula was applied to compare pre and postintervention changes between group A and group B. Group B. A significance level of p-value &lt;0.05 was considered statistically significant. Results: Group A and group B had respective mean ages of 37.07±8.66 years and 41.07±8.66 years. Total of 30 LSS patients were treated. Significant differences were observed in the Numeric Pain Rating Scale (NPRS) (p-value&lt;0.0001), Straight Leg Raise (SLR) (p &lt; 0.001), Slump Test (p-value&lt;0.0001), and Self-paced Walking Test (SPWT) (p-value &lt;0.0001). Minimal significance was noted in the Modified Oswestry Disability Index (MODI) (p-value=0.027) and Swiss Spinal Stenosis Questionnaire (SSSQ) (p-value=0.029). Conclusion: Hamstring release and neural mobilisation improve pain, neural flexibility, walking capacity, disability, and physical activity in LSS patients.

Using Mobile Health (mHealth) Interventions to Optimise Breast Cancer Care: A Scoping Review

Introduction: Mobile phones have become ubiquitous in recent years. This portable device can be efficiently utilised to promote health and deliver high-quality healthcare services via Mobile Health (mHealth) technology interventions. In view of the increasing global burden of breast cancer cases, mHealth interventions can be constructive in breast cancer prevention and management. Nevertheless, there is a paucity of evidence to support the utility of mHealth interventions in breast cancer care. Aim: To analyse and synthesise evidence from published literature on the feasibility and effectiveness of mHealth interventions employed for breast cancer prevention, detection, management, and rehabilitation. Additionally, this study intends to draft a conceptual framework for mHealth intervention strategies in breast cancer management. Materials and Methods: A comprehensive literature search was conducted at Panimalar Medical College Hospital and Research Institute, Chennai, Tamil Nadu, India, from June 2022 to December 2022. Google Scholar and PubMed databases were used to find published articles relevant to the study’s objectives. The reviewers selected articles based on the relevance of the article and eligibility criteria. Articles on mHealth interventions for the female population above 18 years of age with breast cancer were included. Results: A total of 13 articles were selected based on the eligibility criteria. Regardless of the type of mHealth technology employed, target population, and purpose of intervention, all the studies strongly support the use of mHealth technologybased interventions over usual care to enhance breast cancer management. Conclusion: The use of mHealth applications has increased exponentially in recent years. Since then, many studies have been conducted to validate their use. However, the usability of these applications is not well established. The involvement of not only patients but also healthcare professionals is crucial to develop well-equipped digital health applications. Personalised applications that provide security and safeguard user privacy are highly preferred by patients. A collaborative approach involving patients, healthcare professionals, and application developers will aid in the development of highly efficient mHealth applications.

Species distribution and antimicrobial susceptibility pattern of coagulase-negative staphylococci isolated from clinical specimens at a tertiary care hospital

Background and objectives: Coagulase-negative staphylococci (CoNS) are considered important causative agents of hospital acquired infection. These organisms are found in various clinical specimens from hospitalized patients. Present study was carried out to determine the species distribution and antimicrobial susceptibility pattern of CoNS isolated from clinical specimens at a tertiary care hospital. Materials and methods: CoNS isolated from various clinical samples were included in this study. The isolates were identified by colony morphology, Gram’s staining, catalase and coagulase tests. Further differentiation of species was performed by susceptibility to novobiocin, urease activity and ornithine decarboxylase test. Antibiotic susceptibility testing was performed according to the Clinical and Laboratory Standard Institute (CLSI) guidelines. Results: Total 108 isolates of CoNS were included and analysed. Out of 108 CoNS, S. epidermidis was the most common species (36.1%) followed by S. saprophyticus (23.1%), S. hemolyticus (17.6%), S. hominis (13%) and S. lugdunensis (10.2%). Most of the isolates showed resistance to penicillin, oxacillin, amoxycillin, erythromycin, ciprofloxacin and ofloxacin. All the isolates were sensitive to vancomycin. Conclusions: CoNS emerged as an important nosocomial pathogen and should not be neglected as contaminant. High rate of antimicrobial resistance warrants susceptibility testing prior to the treatment of CoNS. IMC J Med Sci. 2024; 18(1):010.

Research on innovation decisions in industry-university-research cooperation based on differential games

ABSTRACT The lack of innovation power in industry-university-research (IUR) cooperation is one of the important reasons leading to low independent innovation ability in China. Considering the long-term and dynamic nature of IUR innovation effort, the differential game method is used to compare and analyse the optimal decision under four scenarios: independent R&D by enterprises and university-research institutes, tax incentives for enterprises by the government, tax incentives and subsidies by the government, and a Stackelberg game considering the internal cost subsidy of enterprises. The results show that government tax incentives can improve the enthusiasm of enterprises for cooperative innovation, while government subsidies can simultaneously improve the enthusiasm of IUR institutes for cooperative innovation and can enhance the overall benefits of both parties and even the system. When certain conditions are met based on the government’s tax incentive and subsidy policies, the innovation effort, cooperative innovation level and benefits in the Stackelberg game are optimal, and Pareto improvement can be achieved. The optimal benefits of enterprises and university-research institutes, the total benefits of the system, and the optimal trajectory of the cooperative innovation level tend to be stable over time in the four game scenarios.

DIGITAL TRANSFORMATION OF SOCIETY: REFLEXION OF SOCIOLOGICAL EDUCATION

The digital transformation of society has been studied in sociological science for more than a decade, and in recent years especially intensively. At the same time, these processes are not yet reflected in all educational programmes in sociological education. In the proposed article, a statistical analysis of sociological education's reflection on the digitalisation of society is carried out. To obtain the results, we propose the following criteria: the availability of bachelor's and master's degree programmes with a "digital" orientation, the inclusion of "digital" disciplines in non-digital training programmes, and the availability of relevant literature for modern sociology students. The research has revealed a wider spread of educational programmes and offered disciplines of digital content in Master's degree programmes than in Bachelor's degree programmes. It also suggests that the existing stratification of universities (research institutes, federal, core, etc.) manifests itself as a kind of digital inequality - some universities can afford training in accordance with the requirements of digitalisation, while others lack the resources to do so. At the same time, the reflection of the digitalisation of society is still positive.

PELATIHAN PENGEMBANGAN LITERASI DAN NUMERASI TERHADAP GURU MTSS NURUL QURAN KABUPATEN BIREUEN PROVINSI ACEH

Literacy and numeracy development are two important components in education that help individuals acquire the skills of reading, writing, understanding information, as well as abilities in mathematics and understanding numbers. These two skills are the basis for success in various aspects of life, including further education, career, and active participation in society. It is important to create an educational environment that supports literacy and numeracy development. The method for implementing community service activities went through several stages, namely pre-preparation, preparation, implementation and closing. Teachers have a key role in teaching and guiding students to develop these skills. In addition, the integration of literacy and numeracy in various subjects and activities outside the classroom helps link these skills to real life. Thus, developing literacy and numeracy is a continuous process that involves collaboration between schools, families and communities to create individuals who have a strong foundation of skills for success in life. Evaluation of activity implementation and sustainability is planned to involve the Almuslim University Research and Community Service Institute. The evaluation carried out by the community service team is the extent to which coaching and mentoring activities for students have had a good impact.

How Do Heterogeneous Networks Affect a Firm's Innovation Performance? A Research Analysis Based on Clustering and Classification.

Based on authorized patents of China's artificial intelligence industry from 2013 to 2022, this paper constructs an Industry-University-Research institution (IUR) collaboration network and an Inter-Firm (IF) collaboration network and used the entropy weight method to take both the quantity and quality of patents into account to calculate the innovation performance of firms. Through the hierarchical clustering algorithm and classification and regression trees (CART) algorithm, in-depth analysis has been conducted on the intricate non-linear influence mechanisms between multiple variables and a firm's innovation performance. The findings indicate the following: (1) Based on the network centrality (NC), structural hole (SH), collaboration breadth (CB), and collaboration depth (CD) of both IUR and IF collaboration networks, two types of focal firms are identified. (2) For different types of focal firms, the combinations of network characteristics affecting their innovation performance are various. (3) In the IUR collaboration network, focal firms with a wide range of heterogeneous collaborative partners can obtain high innovation performance. However, focal firms in the IF collaboration network can achieve the same aim by maintaining deep collaboration with other focal firms. This paper not only helps firms make scientific decisions for development but also provides valuable suggestions for government policymakers.

ИЗМЕНЧИВОСТЬ МОРФОФУНКЦИОНАЛЬНЫХ ПОКАЗАТЕЛЕЙ СТУДЕНТОВ Г. КРАСНОЯРСКА В ЗАВИСИМОСТИ ОТ СОМАТОТИПА

This paper presents a definition of the variability of morphometric parameters of first and second year students of three major universities of the city of Krasnoyarsk, depending on the type of constitution. The study of somatometric indicators is important for determining physical development and general health. The study covered 765 students aged 18 to 20 years (393 girls and 372 boys). Somatometry was carried out according to V.V. Bunak’s methodology, adopted at the Moscow State University Research Institute of Anthropology in the morning with a standard set of tools. The following anthropometric parameters were measured: body length, body weight, girth, anterior-posterior and transverse diameters of the chest. The type of constitution was determined using the Ries-Eysenck index. The hand strength of the right and left hands was measured using a medical electronic manual dynamometer DMER-120-0.5, as well as the index of hand strength as a percentage. In females, the predominant type of constitution according to the Ries-Eysenck index was asthenic, with 57.0 %; in males, the normosthenic type dominated at 45.5 %. The gender heterochrony of the values of the median anthropometric indicators in adolescence, depending on the somatotype, was revealed. Morphometric parameters of body length, girth, transverse and antero-posterior chest diameters, and absolute indicators of carpal dynamometry gradually increase from asthenic to picnical type of constitution, both in boys and girls. The body length is maximal in asthenic somatotype in all subjects. The index of wrist strength is maximum in girls of the asthenic type of constitution and in boys of the normosthenic type, the minimum is in all students of the picnical somatotype. The correlation of absolute values of dynamometry and body weight was determined in all subjects. A moderately pronounced positive relationship was revealed between the values of the index of the wrist strength of the right hand and the chest girth, while the Spearman index in girls is 0.4 (p&lt;0.05), in boys – 0.39 (p&lt;0.05).

Hemolysis and hypersensitive tests ease culture collection management of antagonistic bacteria

A biosafety assessment is a crucial first step in the management of microbial culture collection to screen and determine unexpected potential plant and human pathogenic bacteria. It is common to collect and store as many fresh culture collections from natural resources before being further evaluated for antagonist bacteria. As a result, a bulk of isolates must be preserved which required more effort and budget. Safety evaluations based on the hemolysis and hypersensitive reactions offer simple tests to ease culture collection management of antagonist bacteria. The study aimed to evaluate the safety of bacterial culture collection for their hemolysis and hypersensitive reactions. Ninety-five isolates of rhizosphere and endophytic bacterial isolates from the culture collections of the Department of Plant Protection-IPB University, Indonesian Industrial and Beverages Crops Research Institute, and Indonesian Spice and Medicinal Crops Research Institute, were evaluated their safety using the hemolysis and hypersensitive tests. The hemolysis test was conducted using blood agar media, from which isolates with a negative (?) reaction were then tested for the hypersensitivity reaction on tobacco leaves. Bacterial isolates passed from both hemolysis and hypersensitivity tests were then preserved by the lyophilization method for long-term storage of culture collection. Based on the hemolysis test, 68 out of 95 bacterial isolates (71.57%) were found to be positive (? or ?) reactions. The hypersensitive test showed that 22 of 27 negative hemolysis isolates did not trigger hypersensitivity reactions in tobacco leaves, therefore, they were preserved by lyophilization. The study indicated that a high number of bacterial isolates in the present collection, 68 positive hemolysis, and 5 hypersensitive, need to be re-evaluated due to their safety concerns. The present study highlights the importance of biosafety tests performed in an early stage before the to permanent collection of antagonist isolates.
