Although canine parvovirus (CPV) and canine enteric coronavirus (CCoV) are important enteric pathogens of dogs and have been studied extensively in different parts of the world, there are no reports on these viruses from the Caribbean region. During 2015-2016, a total of 104 diarrheic fecal samples were collected from puppies and adult dogs, with or without hemorrhagic gastroenteritis, on the Caribbean island of St. Kitts (KNA). By PCR, 25 (24%, n=104) samples tested positive for CPV. Based on analysis of the complete deduced VP2 amino acid sequences, 20 of the KNA CPV strains were assigned to new CPV-2a (also designated as CPV-2a-297A). On the other hand, the VP2 genes of the remaining 5 strains were partially characterized, or could not be sequenced. New CPV-2a was the predominant CPV variant in St. Kitts, contrasting the molecular epidemiology of CPV variants reported in most studies from nearby North and South American countries. By RT-PCR, CCoVs were detected in 5 samples (4.8%, n=104). Based on analysis of partial M-protein gene, the KNA CCoV strains were assigned to CCoV-I genotype, and were closely related to CCoV-I strains from Brazil. To our knowledge, this is the first report on detection and genetic diversity of CPV and CCoV in dogs from the Caribbean region, and underscores the importance of similar studies in the other Caribbean islands.

Ross University School of Veterinary Medicine, located on the Caribbean island of St. Kitts in the West Indies, hosted a multi-national, transdisciplinary One Health conference in St. Kitts and Nevis. Historically the many countries of the Caribbean carry a high burden of chronic and infectious disease and struggle with complex economic and developmental issues that continuously pressurize inhabitants and their natural environment. Considering these vast regional challenges, presentations covered diverse topics including community-based approaches for zoonotic disease control and prevention and mitigation of problems at the interface of wildlife, domestic animals, and humans. In two workshops the participants suggested a framework for practicing One Health in the Caribbean that emphasized capacity building and sustainability. Four structural components to the One Health paradigm were discussed including: identification of common problems, the necessity of comprehensive needs assessment, regional mobilization of resources, and building trust among all One Health stakeholders and the public.

Coxiella burnetii is a ubiquitous zoonotic bacterium reported worldwide that causes Q-fever. Infections result in profound economic losses to livestock producers by causing abortions and low birth weights. Current information about the disease in the Caribbean region is scarce. With multiple small islands and territories, it is often considered that the bacterium is absent or circulates at a low prevalence. Our study aimed to determine whether sheep and cattle housed at a veterinary campus in St Kitts had previous exposure to C. burnetii. Blood samples were taken from cattle ( n = 63; 72% of the herd) and sheep ( n = 133; 71% of the flock). Antibodies to C. burnetii were detected by a commercial indirect enzyme-linked immunosorbent assay (IDvet® ELISA) test. The seroprevalence was estimated at 26.3% (95% CI: 19.1–34.7%) in sheep and 0% (95% CI: 0–5.7%) in cattle. Sheep importation to St. Kitts is very rare, thus, these results suggest that C. burnetii is present on the island. The seronegativity of all the cattle highlights the absence of the bacterium on the veterinary campus. The high seroprevalence in sheep, however, has potentially important implications for animal health and public health as well as for wildlife conservation. Further investigation about animal seroprevalence and human exposure are warranted in St. Kitts and in the Caribbean region.

Human exposure to zoonotic parasites via contaminated soil is a much studied area. Less research has been performed on exposure via contact with animals and surfaces such as picnic tables with which infected animals might be in contact. On St. Kitts, wild African green monkeys (AGM; Chlorocebus aethiops sabaeus), which are known to have zoonotic parasites, roam freely in areas with outdoor dining facilities and are used in the tourist industry. In this study, the hands and feet of eight AGM and picnic tables where AGM were known to walk on were examined for parasitic organisms. Six of the AGM had parasitic organisms on their hands and/or feet. Trichuris spp. eggs, hookworm larvae and eggs and pinworm eggs were recovered from the tables. The results of this pilot study highlight other potential means of transfer of zoonotic parasites and suggest that surfaces without obvious fecal material can be contaminated with zoonotic parasites.

Wicked problems in One Health are associated with dynamicity and uncertainty that require experts, authorities and community members to reach for innovative means of collective inquiry, and collaborative interventions to address the deep social issues at the root of interspecies problems. In this study we explore the value of harm reduction concepts to understand a hundreds of year old issue, the St. Kitts’ “monkey problem,” which involves the invasive African green monkey (Chlorocebus sabaeus) as the cause of deleterious effects on agriculture, but concurrent positive effects on tourism and biomedical research. The harm reduction approach, a systems and settings-based approach with decades of success in public health, can serve as a framework to produce action on persistent societal problems. Harm reduction concepts and methods and participatory epidemiology were used to uncover local perceptions about human-monkey interactions and “meet people where they are” by asking the research question: Are there commonalities in perceptions and values linked to the St. Kitts’ “monkey problem” that are shared across diverse representatives of society that can act as a common starting place to launch collaborative responses to this invasive species? Through a series of focus group activities and interviews we found that the Kittitian “monkey problem” is a contentious and dichotomous problem pervasive in most of society that has no single stakeholders nor one solution. Harm reduction helped to map the island’s human-monkey system and elucidated an entry point toward tackling this problem through the identification of shared values, and also provided a model for incremental gains that may be achieved. Likening the St. Kitts “monkey problem” to a wicked problem enabled stakeholders to seek more options to manage the problem rather than to conclusively solve it. Frequently mentioned shared values including the protection of farmer crops and backyard harvests likely represent strong entry points to this problem and a jumping-off point to begin collective action toward future improvements.
