Mapping Social Support Sources for Rural Patients with Chronic Illness

Objective: In this study, we evaluated social support sources for rural residents with chronic conditions and examined associations between support sources and self-reported health status. Methods: Adults in rural zip codes across the United States (N = 183; 48.6% female) participated in an online survey. Chronic disease status was determined through participant self-report of prior medical diagnoses. Support sources were elicited using scenarios that require illness assistance or emotional support. Self-rated physical and mental health were measured using 5-point Likert scales. Chi-square tests examined gender differences in preferred sources of social support. Ordinal logistic regressions assessed predictors of self-rated health status, including support source preferences. Results: Family and friends were found to be primary sources of social support for rural residents managing illness. Women tended to rely more heavily on close family members whereas men were open to more diverse sources. Gender differences were statistically significant (χ2(4) = 20.66, p < .001). Those relying on close friends rather than family when sick also reported better physical health (B = 1.79, Wald = 4.91, p = .02). Conclusion: Findings indicate informal social ties are central for the health of rural populations. Gender differences in help-seeking patterns may necessitate tailored chronic disease interventions. Fostering community linkages and leveraging natural supports will be vital for addressing rural health disparities.

Facilitating and barrier factors to the implementation of a transitional care program: a qualitative study of hospital coordinators in South Korea

BackgroundTransitional care is an integrated service to ensure coordination and continuity of patients’ healthcare. Many models are being developed and implemented for this care. This study aims to identify the facilitators and obstacles of project performance through the experiences of the coordinator in charge of the Community Linkage Program for Discharge Patients (CLDP), a representative transitional care program in Korea.MethodForty-one coordinators (nurses and social workers) from 21 hospitals were interviewed using a semi-structured questionnaire, and thematic analysis was performed.ResultThree themes were found as factors that facilitate or hinder CLDP: Formation and maintenance of cooperative relationships; Communication and information sharing system for patient care; and interaction among program, regional, and individual capabilities. These themes were similar regardless of the size of the hospitals.ConclusionA well-implemented transitional care model requires a program to prevent duplication and form a cooperative relationship, common computing platform to share patient information between institutions, and institutional assistance to set long-term directions focused on patient needs and support coordinators’ capabilities.

Skeleton coupling: a novel interlayer mapping of community evolution in temporal networks

Abstract Dynamic community detection (DCD) in temporal networks is a complicated task that involves the selection of a method and its associated hyperparameters. How to choose the most appropriate method generally depends on the type of network being analysed and the specific properties of the data that define the network. In functional temporal networks derived from neuronal spike train data, communities are expected to be transient, and it is common for the network to contain multiple singleton communities. Here, we compare the performance of different DCD methods on functional temporal networks built from synthetic neuronal time series data with known community structure. We find that, for these networks, DCD methods that utilize interlayer links to perform community carry over between layers outperform other methods. However, we also observe that DCD performance is highly dependent on the topology of interlayer links, especially in the presence of singleton and transient communities. We therefore define a novel way of defining interlayer links in temporal networks called skeleton coupling that is specifically designed to enhance the linkage of communities in the network throughout time based on the topological properties of the community history. We show that integrating skeleton coupling with current DCD methods improves the method’s performance in synthetic data with planted singleton and transient communities. The use of skeleton coupling to perform DCD will therefore allow for more accurate and interpretable results of community evolution in real-world neuronal data or in other systems with transient structure and singleton communities.

Participant Perspectives on the Implementation of a School-Linked Text-Message Intervention to Improve Pediatric Asthma Medication Adherence.

Background: Poor adherence to inhaled corticosteroids (ICS) is a significant challenge in pediatric asthma, contributing to health inequities. Text-message reminders for ICS therapy are an evidence-based approach that improves pediatric asthma medication adherence, yet has not been widely adopted into practice, partly due to lack of (1) participant input on design and implementation and (2) use of sustainable community linkages. Remote Asthma Link™ (RAL) seeks to fill this gap as a school-linked text-message intervention wherein parents of children with poorly controlled asthma received daily, 2-way text-message reminders for preventive inhaler use. Responses were shared with school nurses who conducted remote check-ins with families. Enrolled children, largely from underserved backgrounds, experienced improvements in medication adherence and asthma health outcomes. While initial results were promising, we have yet to elicit participant input to refine the protocol for more widespread implementation. Objective: Examine participant perspectives on barriers and facilitators of RAL implementation. Methods: Semistructured interviews were conducted May-June 2022 with intervention participants: 10 parents, 7 school nurses, and 4 pediatric providers (n = 21) until thematic saturation was reached. Interview transcripts were coded using thematic analysis. Results: Several facilitators for RAL implementation were identified, including ease of use and accessibility, personal connection to the school nurse, and receipt of a visual notification for habit formation. Barriers included challenges with school nurses reaching parents, poor understanding of program expectations, and lack of reimbursement structure. Participant-proposed solutions to barriers included utilizing alternate communication methods (eg, social media), educational sessions, and meeting with payors to consider reimbursement models. Conclusion: RAL is a school-linked text-message intervention demonstrating promise in improving outcomes and equity in asthma care. Key implementation facilitators, barriers, and proposed solutions will inform protocol adaptations to promote successful implementation of this and other text-message interventions into clinical practice.

Impact of transformational leadership and school environment on organizational commitment of teachers

Purpose: This study investigated the influence of transformational leadership and the school environment on the organizational commitment of teachers. Research methodology: A quantitative nonexperimental research design with multiple regression analysis was employed. Using the Raosoft calculator, 115 of the 162 public secondary teachers in Davao City were selected as respondents who rated the three adopted questionnaires. Results: The findings revealed a high level of transformational leadership, school environment, and teachers’ organizational commitment. In terms of significant relationships, both transformational leadership and the school environment were moderately positive and statistically significant. The results of the regression revealed that transformational leadership and the school environment are responsible for 46.2% of the variation in the organizational commitment of teachers. However, the results of the coefficients revealed that only the school environment could predict organizational commitment. Limitations: This study only involved 115 respondents and used adopted questionnaires, which might be quite different from the context of the respondents. Contribution: The results and findings of this study can be used as a basis for implementing programs and interventions to address problems with teachers’ organizational commitment. Novelty: Previous studies have only focused on some variables that influence organizational commitment, such as remoteness, emotional exhaustion, inaccessibility of healthy and sufficient school accommodations, and lack of local community linkages without a clear theoretical framework. Fortunately, this study explored other relevant factors, such as leadership and the school environment, as predictors of organizational commitment by establishing related theories to strongly support these variables with corresponding indicators.

Examining the Sustainability of Core Capacity and Evidence-Based Interventions for FIT-Based CRC Screening: California Colorectal Cancer Control Program.

We examined the extent to which funded satellite clinics could sustain the California Colon Cancer Control Program (C4P) strategies implemented in health systems to increase uptake of the fecal immunochemical test (FIT) or immunochemical fecal occult blood test (iFOBT) for colorectal cancer (CRC) screening in the absence of future C4P funds. Seven health systems consisting of 38 satellite clinics participated in C4P to examine the sustainability of the program in the absence future Centers for Disease Control and Prevention (CDC) funding. Quantitative and qualitative methods with a close and open-ended survey approach, and a prospective cohort design were used to examine the sustainability of the C4P in health systems. A total of 61% of satellite clinics could not sustain funding stability. Only 26% could sustain funding stability. About, 71%, 26%, and 21% of the satellite clinics could sustain the small media platform, patient navigation services, and community health workers (CHWs), respectively. All the satellite clinics sustained the provider reminder system and professional development. Roughly, 71% and 42% of funded satellite clinics could not sustain the patient navigators and CHWs, respectively. The satellite clinics that could sustain funding stability, sustained patient navigation services and CHWs. Health systems that could not sustain funding stability, could not sustain patient navigation services and CHWs. Qualitatively, the need to support uninsured priority populations, health educators, patient navigators, care coordination activities, outreach services, and provision of enhanced services emerged. The need to support enhanced quality measures, expansion of funding, Medi-Cal Public Hospital Redesign and Incentive coverage, health plan, community linkages, resource sharing, and best practices specifically on CRC screening emerged. Themes such as automated reminder, limited personalized care delivery and capacity, transportation barriers, staff salary, expansion of care through patient navigation, and culturally appropriate media campaign also emerged. Overall, to address sustainability barriers, funding stability should be maintained in the health systems.

Global prediction of soil microbial growth rates and carbon use efficiency based on the metabolic theory of ecology

Soil microbial growth rate and microbial carbon use efficiency (CUE) are critical parameters of soil microbial carbon metabolism, moderating soil organic carbon (SOC) dynamics. However, global patterns of soil microbial growth rate and microbial CUE are still unresolved. Here, we show that the metabolic theory of ecology (MTE) can be applied to model soil microbial growth rate at the global scale as a function of microbial biomass, temperature, and SOC contents. Rates of soil microbial growth were modeled at depths of 0–30 cm and calibrated against rates measured with the 18O-labeled H2O incubation method. The modeled soil microbial growth rates were strongly driven by temperature. They decreased with latitude and had greater seasonal variations in tundra and boreal forest compared to tropical biomes. Soil microbial CUE (0–30 cm) ranged from 0.25 to 0.63 among global biomes, averaging at 0.43. Modeled annual soil microbial growth rates followed the same global patterns and were on the same order of magnitude as other key ecosystem C fluxes such as net primary productivity, litterfall, and heterotrophic respiration. This indicates a strong functional linkage of aboveground and belowground communities at the global scale. Our MTE-based approach provides the first estimates of global patterns for soil microbial growth rate and microbial CUE and potentially provides a powerful mechanistic framework to incorporate soil microbes into Earth System Models.

Preservation of the Indigenous Medicinal Knowledge Network of the Bonda Tribe

For tribal people to preserve their historical legacy and advance environmentally friendly healthcare habits, traditional medicinal knowledge must be preserved. This is especially true for the Bonda tribe in the Malkangiriarea of Odisha. The Bonda tribe, who live in the Eastern Ghats, mostly depend on narrative Indigenous Medicinal Knowledge (IMK) shared among elders and traditional healers (Desaris). This study investigated the processes of knowledge transmission, the social networks that sustained the IMK system, and the preservation and ways adopted in Bonda Community. Data were gathered from multiple Bonda villages using purposive sampling technique during 2023-24 years. Qualitative methods and participatory research were used for data collection, and chord diagrams were used for visualization. The results showed a strong IMK network with important contributions from Desaris and strong community linkages. The preservation of sanctified groves and therapeutic herbs through conservation techniques, incorporating new information and preserving transmission secrecy were examples of adaptation tactics. This investigation promoted approaches that encouraged safeguarding Indigenous Medicinal Knowledge (IMK) by highlighting the significance of Indigenous Knowledge Network (IKN) in maintaining traditional identities and social well-being.

Pre-Service Teacher Competence in a Teacher Education Institution

This study aimed to describe the level of competence of pre-service teachers of Camarines Norte State College College of Education in terms of the Philippine Professional Standards for Teachers (PPST) and the significant relationship between their academic performance and level of competence. The study employed the descriptive-correlational research design. Data used in this study came from a survey of BSEd and BEEd pre-service teachers (n=125) and cooperating teachers (n=125) in Camarines Norte, Philippines. A questionnaire consisting of the specific indicators of the PPST was the main data-gathering instrument. The study revealed that the pre-service teachers had an advanced level of competence in Content Knowledge and Pedagogy, Learning Environment, Curriculum and Planning, Community Linkages and Professional Engagement, Personal Growth and Professional Development, and above average level of competence along Diversity of Learners and Assessment and Reporting domains of the PPST. Policies and programs were proposed to improve the level of competence of the pre-service teachers.

Assessing a pilot scheme of intensive support and assertive linkage in levels of engagement, retention, and recovery capital for people in recovery housing using quasi-experimental methods

IntroductionStrong and ever-growing evidence highlights the effectiveness of recovery housing in supporting and sustaining substance use disorder (SUD) recovery, especially when augmented by intensive support that includes assertive linkages to community services. This study aims to evaluate a pilot intensive recovery support (IRS) intervention for individuals (n = 175) entering certified Level II and III recovery residences. These individuals met at least three out of five conditions (no health insurance; no driving license; substance use in the last 14 days; current unemployment; possession of less than $75 capital). The study assesses the impact of the IRS on engagement, retention, and changes in recovery capital, compared to the business-as-usual Standard Recovery Support (SRS) approach (n = 1758). MethodsThe study employed quasi-experimental techniques to create weighted and balanced counterfactual groups. These groups, derived from the Recovery Capital assessment tool (REC-CAP), enabled comparison of outcomes between people receiving IRS and those undergoing SRS. ResultsAfter reweighting for resident demographics, service needs, and barriers to recovery, those receiving IRS exhibited improved retention rates, reduced likelihood of disengagement, and growth in recovery capital after living in the residence for 6–9 months. ConclusionThe results from this pilot intervention indicate that intensive recovery support, which integrates assertive community linkages and enhanced recovery coaching, outperforms a balanced counterfactual group in engagement, length of stay, and recovery capital growth. We suggest that this model may be particularly beneficial to those entering Level II and Level III recovery housing with lower levels of recovery capital at admission.

MULTISECTOR COLLABORATION DRIVES THE DEVELOPMENT OF THE FOURTH HEALTHY BRAIN INITIATIVE ROAD MAP

Abstract Partnerships and collaboration across sectors played a critical role in the development of the fourth edition of the Healthy Brain Initiative Road Map (Road Map). The public health community, leaders in related fields, and people living with dementia contributed to the development and review. The Alzheimer’s Association and CDC invited 20 national leaders from public health, aging, academia, health care and health systems to guide the development of the fourth HBI Road Map as a part of the Leadership Committee. Their contributions included reviewing data, setting the overall direction of the review and leading five workgroups, composed of 68 subject-matter experts, who recommended actions on Risk Reduction of Cognitive Decline; Timely Detection, Diagnosis and Management of Cognitive Impairment; Dementia Caregiving; Health Equity; and Community Linkages. Health departments offered input through facilitated listening sessions and an open input period. Their feedback emphasized the importance increased information on health equity and partnerships in the Road Map. The Leadership Committee also advised continued partner engagement through the review process. This translated to review by the Alzheimer’s Association, CDC subject matter experts, external health equity experts, the Leadership Committee, workgroup members, the Healthy Brain Initiative Collaborative, the Alzheimer’s Association Early Stage Advisory Group and ultimately CDC leadership. This presentation will explore important themes that emerged throughout this process that shaped the design and evolution of the HBI Road Map series to its most recent iteration, as a guiding document with health equity and multi-sector collaboration action at its core.

A SYSTEMS APPROACH TO PRACTICE TRANSFORMATION FOR BRAIN HEALTH INTEGRATION INTO COMMUNITY HEALTH CENTER SERVICES

Abstract Community Health Centers are America’s largest and most successful primary care system, providing access to quality healthcare services to more than 30 million Americans through more than 14,000 service delivery locations regardless of patients’ ability to pay. The National Association of Community Health Centers (NACHC) provides the training and education that health centers need to advance practice transformation and improve care delivery models to succeed in value-based care and meet the needs of patient populations. Through the Value Transformation Framework (VTF), NACHC provides an approach to support health center systems change, organizes and distills evidence-based interventions, provides knowledge, tools and resources, and links performance to the Quintuple Aim – improved health outcomes, patient and staff experience, reduced costs, and equity. NACHC guides health centers in the application of the VTF through a nation-wide learning community, Elevate. Health center participation in Elevate is linked to improved performance on clinical quality measures, improved patient and staff experiences, and reduced costs. Within the Elevate, NACHC successfully implemented a learning track focused on brain health, offering health center-specific guidance on a clinical introduction to Dementia early detection/risk reduction; incorporating Dementia early detection/risk reduction into care management workflows and leveraging reimbursement opportunities; and strengthening community linkages and partnerships to support Dementia early detection/risk reduction. Evaluation data from this learning track indicates health center interest in continuing education related to brain health integration into health center services. This topic is especially relevant considering the increasing population segment of older adult patients that health centers serve.

Feasibility testing of an interprofessional education intervention to support collaborative practice in home care for older stroke survivors with multiple chronic conditions

ABSTRACT This mixed-methods study examined the feasibility of implementing a new six-month, theory-based, interprofessional education intervention, and explored its effects and impact on collaborative practice among home care providers caring for older adult stroke survivors (≥65) with multiple chronic conditions. The evaluation utilized a qualitative descriptive and one group repeated measures design which included participant questionnaires, focus groups and field notes. Participants included 37 home care providers (registered nurses, physiotherapists, occupational therapists, personal support workers, care coordinators, and their supervisors) in Ontario, Canada. The intervention was feasible and acceptable to home care providers. Perceived benefits included improved communication and collaboration within teams, enhanced role understanding, increased learning with and from each other, and increased appreciation of all team members’ expertise. From 3 to 6 months post initial IPE training, there was a statistically significant improvement in three domains of collaborative practice as measured by the Collaborative Practice Assessment Tool (communication/information exchange; community linkage and coordination of care; decision-making and conflict management) and one domain of collaborative practice, as measured by the 19-item Team Climate Inventory (task orientation). Implications for implementing interprofessional education in home care practice settings are described. Further testing in other populations and settings is warranted.

Analogous assembly mechanisms and functional guilds govern prokaryotic communities in mangrove ecosystems of China and South America.

As an important coastal "blue carbon sink," mangrove ecosystems contain microbial communities with an as-yet-unknown high species diversity. Exploring the assemblage and structure of sediment microbial communities therein can aid in a better understanding of their ecosystem functioning, such as carbon sequestration and other biogeochemical cycles in mangrove wetlands. However, compared to other biomes, the study of mangrove sediment microbiomes is limited, especially in diverse mangrove ecosystems at a large spatial scale, which may harbor microbial communities with distinct compositions and functioning. Here, we analyzed 380 sediment samples from 13 and 8 representative mangrove ecosystems, respectively, in China and South America and compared their microbial features. Although the microbial community compositions exhibited strong distinctions, the community assemblage in the two locations followed analogous patterns: the assemblages of the entire community, abundant taxa, rare taxa, and generalists were predominantly driven by stochastic processes with significant distance-decay patterns, while the assembly of specialists was more likely related to the behaviors of other organisms in or surrounding the mangrove ecosystems. In addition, co-occurrence and topological network analysis of mangrove sediment microbiomes underlined the dominance of sulfate-reducing prokaryotes in both the regions. Moreover, we found that more than 70% of the keystone and hub taxa were sulfate-reducing prokaryotes, implying their important roles in maintaining the linkage and stability of the mangrove sediment microbial communities. This study fills a gap in the large-scale analysis of microbiome features covering distantly located and diverse mangrove ecosystems. Here, we propose a suggestion to the Mangrove Microbiome Initiative that 16S rRNA sequencing protocols should be standardized with a unified primer to facilitate the global-scale analysis of mangrove microbiomes and further comparisons with the reference data sets from other biomes.IMPORTANCEMangrove wetlands are important ecosystems possessing valuable ecological functions for carbon storage, species diversity maintenance, and coastline stabilization. These functions are greatly driven or supported by microorganisms that make essential contributions to biogeochemical cycles in mangrove ecosystems. The mechanisms governing the microbial community assembly, structure, and functions are vital to microbial ecology but remain unclear. Moreover, studying these mechanisms of mangrove microbiomes at a large spatial scale can provide a more comprehensive insight into their universal features and can help untangle microbial interaction patterns and microbiome functions. In this study, we compared the mangrove microbiomes in a large spatial range and found that the assembly patterns and key functional guilds of the Chinese and South American mangrove microbiomes were analogous. The entire communities exhibited significant distance-decay patterns and were strongly governed by stochastic processes, while the assemblage of specialists may be merely associated with the behaviors of the organisms in mangrove ecosystems. Furthermore, our results highlight the dominance of sulfate-reducing prokaryotes in mangrove microbiomes and their key roles in maintaining the stability of community structure and functions.

Care of Healthy as well as Sick Newborns in India: A Narrative Review.

Majority of neonatal deaths occur in developing countries. There is an increase in the proportion of neonatal deaths as part of the under-5 mortality over the past decade. Hence we need to accelerate further to achieve the goal of single digit neonatal mortality rate (NMR) by 2030. The two major arms of NMR reduction include facility-based neonatal care (FBNC) and home-based neonatal care (HBNC). FBNC addresses care at birth, care of the normal newborn, and care of small and sick newborns. HBNC provides continuum of care for newborn and post-natal mothers facilitated by Accredited Social Health Activist (ASHA) workers. One of the main challenges is to maintain good quality of neonatal care. Zero separation, linkage of community & facility and roles of professional bodies are considered way forward to achieve India Newborn Action Plan(INAP) goals. This review summarizes existing programs for newborn health and diseases and provides an over-arching view of the way-forward.

Applying a Power and Gender Lens to Understanding Health Care Provider Experience and Behavior: A Multicountry Qualitative Study.

A limited but growing body of literature shows that health care providers (HCPs) in reproductive, maternal, and newborn health face challenges that affect how they provide services. Our study investigates provider perspectives and behaviors using 4 interrelated power domains-beliefs and perceptions; practices and participation; access to assets; and structures-to explore how these constructs are differentially experienced based on one's gender, position, and function within the health system. We conducted a framework-based secondary analysis of qualitative in-depth interview data gathered with different cadres of HCPs across Kenya, Malawi, Madagascar, and Togo (n=123). We find across countries that power dynamics manifest in and are affected by all 4 domains, with some variation by HCP cadre and gender. At the service interface, HCPs' power derives from the nature and quality of their relationships with clients and the community. Providers' power within working relationships stems from unequal decision-making autonomy among HCP cadres. Limited and sometimes gendered access to remuneration, development opportunities, material resources, supervision quality, and emotional support affect HCPs' power to care for clients effectively. Power manifests variably among community and facility-based providers because of differences in prevailing hierarchical norms in routine and acute settings, community linkages, and type of collaboration required in their work. Our findings suggest that applying power-and secondarily, gender lenses-can elucidate consistencies in how providers perceive, internalize, and react to a range of relational and environmental stressors. The findings also have implications on how to improve the design of social behavior change interventions aimed at better supporting HCPs.

Teaching Competence and Adversity Quotient of Teachers in Alternative Learning System (ALS) and Students’ Learning Engagement in The City Schools Division Offices in the Province of Laguna

This study attempted to determine the ALS teachers’ teaching competence and adversity quotient as predictors of students’ learning engagement in the city schools division offices in the Province of Laguna. Specifically, it investigated the respondents’ level of teaching competence in terms of content knowledge and pedagogy, learning environment, diversity of learners, curriculum and planning, community linkages and professional engagement and professional growth and professional development; respondents’ level of adversity quotient and its dimensions; control, ownership, reach and endurance, and level of students’ learning engagement. The findings showed that the overall weighted mean of 3.64 revealed that the ALS teachers’ teaching competence was very high; while the overall weighted mean of 2.76 revealed that the respondents’ AQ level was high. Moreover, the findings showed that the average weighted mean of 3.31 revealed that the level of the students’ learning engagement was very high. Meanwhile, the findings showed that the relationship between the respondents’ level of teaching competence and level of adversity quotient were all greater than the 0.01 significance level. Therefore, there was no significant relationship between the ALS teachers’ teaching competence and their level of adversity quotient was observed. In addition, the finding showed that the relationship between the respondents’ teaching competence and students’ learning engagement were less than the test of significance at 0.01 leading to the rejection of the null hypotheses. This showed that there was a significant relationship between the respondents’ teaching competence and student learning engagement. Lastly, the relationship between the respondents’ level of adversity quotient and level of students’ learning engagement were higher than the test of significance at 0.01 leading to the acceptance of the null hypotheses. This shows that there was no relationship between the respondents’ level of adversity quotient and the level of student learning engagement.

Cancer equity for those impacted by mass incarceration.

The cancer disparities between people with incarceration histories compared with those who do not have those histories are vast. Opportunities for bolstering cancer equity among those impacted by mass incarceration exist in criminal legal system policy; carceral, community, and public health linkages; better cancer prevention, screening, and treatment services in carceral settings; expansion of health insurance; education of professionals; and use of carceral sites for health promotion and transition to community care. Clinicians, researchers, persons with a history of incarceration, carceral administrators, policy makers, and community advocates could play a cancer equity role in each of these areas. Raising awareness and setting a cancer equity plan of action are critical to reducing cancer disparities among those affected by mass incarceration.

A Pseudomonas Lysogenic Bacteriophage Crossing the Antarctic and Arctic, Representing a New Genus of Autographiviridae.

Polar regions tend to support simple food webs, which are vulnerable to phage-induced gene transfer or microbial death. To further investigate phage-host interactions in polar regions and the potential linkage of phage communities between the two poles, we induced the release of a lysogenic phage, vB_PaeM-G11, from Pseudomonas sp. D3 isolated from the Antarctic, which formed clear phage plaques on the lawn of Pseudomonas sp. G11 isolated from the Arctic. From permafrost metagenomic data of the Arctic tundra, we found the genome with high-similarity to that of vB_PaeM-G11, demonstrating that vB_PaeM-G11 may have a distribution in both the Antarctic and Arctic. Phylogenetic analysis indicated that vB_PaeM-G11 is homologous to five uncultured viruses, and that they may represent a new genus in the Autographiviridae family, named Fildesvirus here. vB_PaeM-G11 was stable in a temperature range (4-40 °C) and pH (4-11), with latent and rise periods of about 40 and 10 min, respectively. This study is the first isolation and characterization study of a Pseudomonas phage distributed in both the Antarctic and Arctic, identifying its lysogenic host and lysis host, and thus provides essential information for further understanding the interaction between polar phages and their hosts and the ecological functions of phages in polar regions.
