RESUMO

INTRODUCTION: The conceptual framework of One Health (OH) provides a strategy for promoting collaboration across the nexus of animal, human, and environmental health, which is essential for tackling emerging disease threats, such as COVID-19. However, there is no accreditation requirement for OH to prepare students across the professions for collaborative practice. This study aimed to explore the perspectives of faculty across the medical, veterinary, and public health programs about the need, opportunities, and challenges of developing OH in the curricula. METHODS: In this qualitative study, faculty across the three disciplines were invited to participate in audio-recorded, focus group interviews. Recordings were transcribed verbatim and analyzed using inductive and deductive thematic analysis. RESULTS: All participants recognized the need for OH as a critical concept for preparing students for collaborative practice. Opportunities were identified for shared learning and research across the disciplines, particularly through the use of interprofessional education. The lack of an accreditation mandate for OH in the medical curriculum was perceived to be the greatest challenge, leading to an anticipation of significant resistance among medical educators and students. DISCUSSION: Successful development of OH in all three curricula is vital to prepare students for current and future threats to global health. The role of accreditation bodies in ensuring medical, veterinary, and public health curricula prepare students for these threats is crucial. Implications for practice include strategies for persuading medical educators and medical students to embrace OH in the curriculum and promote a culture of shared learning.

RESUMO

Rabies virus is the only Lyssavirus species found in the Americas. In discussions about rabies, Latin America and the Caribbean are often grouped together. Our study aimed to independently analyse the rabies situation in the Caribbean and examine changes in rabies spatiotemporal epidemiology. A questionnaire was administered to the 33 member countries and territories of the Caribbean Animal Health Network (CaribVET) to collect current data, which was collated with a literature review. Rabies was endemic in ten Caribbean localities, with the dog, mongoose, and vampire bat identified as enzootic reservoirs. The majority of animal cases occurred in Puerto Rico, the Dominican Republic, and Haiti, while human cases only consistently occurred in the latter two areas. Rabies vaccination was conducted for high-risk animal populations with variable coverage, and rabies diagnostic capacities varied widely throughout the region. Illegal importation and natural migration of animals may facilitate the introduction of rabies virus variants into virus-naïve areas. Passive surveillance, together with enhanced methods and serological screening techniques, can therefore be of value. The insularity of the Caribbean makes it ideal for conducting pilot studies on reservoir host population management. Best practice guidelines developed for these reservoir hosts can be individually modified to the epidemiological status and available resources within each locality.

RESUMO

This study determined whether multilocus sequence types (MLST) of Campylobacter from poultry in 2 farms in Grenada, West Indies, differed by farm, antimicrobial resistance and farm antibiotic use. Farm A used fluoroquinolones in the water and Farm B used tetracyclines. The E-test was used to determine resistance of isolates to seven antibiotics. PCR of the IpxA gene confirmed species and MLST was used to characterize 38 isolates. All isolates were either C. jejuni or C. coli. Farm antibiotic use directly correlated with antimicrobial resistance of Campylobacter isolates. Almost 80% of the isolates from Farm A were fluoroquinolone resistant and 17.9% of the isolates from Farm B were fluoroquinolone resistant. All Campylobacter isolates from Farm A were tetracycline sensitive, whereas 35.7% of isolates from Farm B were tetracycline resistant. Six previously recognized sequence types (STs) and 2 novel STs were identified. Previously recognized STs were those overwhelmingly reported from poultry and humans globally. Isolates with the same ST did not always have the same antibiotic resistance profile. There was little ST overlap between the farms suggesting that within-farm transmission of Campylobacter genotypes may dominate. MLST typing was useful for tracking Campylobacter spp. among poultry units and can help elucidate Campylobacter host-species population structure and its relevance to human health.
