Development of an OIE Harmonized Day 1 Competency-Based Veterinary School Curriculum in Ethiopia: A Partnership Model for Curriculum Evaluation and Implementation.

The University of Gondar College of Veterinary Medicine and Animal Sciences (UoG-CVMASc) and the Ohio State University College of Veterinary Medicine (OSU-CVM) developed an objective methodology to assess the curriculum of veterinary institutions and implement changes to create a curriculum that is harmonized with OIE standards while also covering the needs and realities of Gondar and Ethiopia. The process, developed under the sponsorship of the World Organisation for Animal Health (OIE) Veterinary Education Twinning Programme, is outlined in this article with the hope that it can be applied by other countries wishing to improve national veterinary services (VS) through the improvement of their academic programs. The plan created by the UoG-OSU Twinning team consisted of an in-depth curriculum assessment and development process, which entailed three consecutive stages. Stage 1 (Curriculum Assessment) included the design and development of an Evaluation Tool for OIE Day 1 Graduating Veterinarian Competencies in recent graduates, and the mapping and evaluation of the current UoG-CVMASc curriculum based on the OIE Veterinary Education Core Curriculum. Stage 2 (Curriculum Development) consisted of the identification and prioritization of possible solutions to address identified curriculum gaps as well as the development of an action plan to revise and update the curriculum. Finally, Stage 3 (Curriculum Implementation) focused on the process to launch the new curriculum. In September 2017, 53 first-year students started the professional program at the UoG-CVMASc as the first cohort to be accepted into the newly developed OIE Harmonized Curriculum, the first of its kind in Africa.

Complaints associated with animal feeding facilities as reported to Ohio local health departments, 2006-2008.

Confined animal feeding facilities of all sizes have long been targeted as a source of human health and quality of life concerns. In order to describe and quantify these concerns in Ohio, a retrospective survey of local health departments was conducted focusing on reported complaints associated with animal feeding facilities. During 2006-2008, the most common complaints pertaining to any type of animal feeding facility were air quality and odor outside the home, followed by manure storage and application issues. The study described here showed that larger permitted livestock feeding facilities were not a major source of health and nuisance complaints associated with animal feeding facilities as reported to Ohio local health departments. Local health departments received few health complaints associated with any animal feeding facility. None were validated or confirmed by a physician in 2008.

Shelter dog behavior after adoption: Using the C-BARQ to track dog behavior changes through the first six months after adoption.

Despite millions of dogs entering and exiting shelters annually, little is known about dog behavior long-term after adoption. Entering a shelter is stressful for dogs which may inhibit or exaggerate behavior. There is a common public sentiment that dogs have a "honeymoon period" after adoption where dogs do not show their full repertoire of behaviors, both positive and negative, until getting more comfortable in their new home. The aim of this prospective observational cohort study was to identify prevalence of and changes in behavior issues in dogs throughout the first six months following adoption. The owners of ninety-nine dogs adopted from five Ohio shelters between October 1, 2020 and June 1, 2021 were surveyed 7, 30, 90, and 180 days after adoption, using the Canine Behavioral Assessment & Research Questionnaire (C-BARQ). Owners were also asked about household changes that may affect behavior. Estimated age, sex, weight, length of shelter stay, shelter intake reason, use of gastrointestinal, antibiotic, and psychotropic medications in the shelter, whether the animal had been previously returned to the shelter, and whether the owner was a first-time dog owner, were evaluated as predictors in a mixed effect regression model of different behavior measures over time. At various timepoints, dogs showed high prevalence for stranger-directed aggression (81.7%), owner-directed aggression (32.3%), dog-directed aggression (75%), familiar dog aggression (37.8%), stranger directed fear (58.2%), nonsocial fear (95.8%), dog directed fear (80.0%) and separation-related behaviors (92.6%). Over 180 days, stranger-directed aggression, excitability, touch sensitivity, training difficulty, and chasing increased, while separation-related behaviors, attachment and attention-seeking decreased. Owners reported high satisfaction with their dogs' behavior. Use of psychotropic medications in the shelter was predictive of stranger-directed aggression and touch sensitivity at home. These findings help veterinarians and shelter professionals council owners on potential behavior changes after adoption.

Quantifying intra- and inter-species contact rates at supplemental feeding sites in Ethiopia to inform rabies maintenance potential of multiple host species.

Rabies, a multi-host pathogen responsible for the loss of roughly 59,000 human lives each year worldwide, continues to impose a significant burden of disease despite control efforts, especially in Ethiopia. However, how species other than dogs contribute to rabies transmission throughout Ethiopia remains largely unknown. In this study, we quantified interactions among wildlife species in Ethiopia with the greatest potential for contributing to rabies maintenance. We observed wildlife at supplemental scavenging sites across multiple landscape types and quantified transmission potential. More specifically, we used camera trap data to quantify species abundance, species distribution, and intra- and inter-species contacts per trapping night over time and by location. We derived a mathematical expression for the basic reproductive number (R0 ) based on within- and between-species contract rates by applying the next generation method to the susceptible, exposed, infectious, removed model. We calculated R0 for transmission within each species and between each pair of species using camera trap data in order to identify pairwise interactions that contributed the most to transmission in an ecological community. We estimated which species, or species pairs, could maintain transmission ( R 0 > 1 ${R_0} > 1$ ) and which species, or species pairs, had contact rates too low for maintenance ( R 0 < 1 ${R_0} < 1$ ). Our results identified multiple urban carnivores as candidate species for rabies maintenance throughout Ethiopia, with hyenas exhibiting the greatest risk for rabies maintenance through intra-species transmission. Hyenas and cats had the greatest risk for rabies maintenance through inter-species transmission. Urban and peri-urban sites posed the greatest risk for rabies transmission. The night-time hours presented the greatest risk for a contact event that could result in rabies transmission. Overall, both intra- and inter-species contacts posed risk for rabies maintenance. Our results can be used to target future studies and inform population management decisions.

Barriers and opportunities for canine rabies vaccination campaigns in Addis Ababa, Ethiopia.

BACKGROUND: Canine rabies is endemic in Ethiopia and presents a significant burden for both animal and human health. We investigate barriers to dog vaccination in Addis Ababa, Ethiopia. These results can be utilized to improve and target future rabies control efforts. METHODOLOGY/PRINCIPLE FINDINGS: During May of 2017, dog owners were surveyed during a free canine rabies vaccination programs that utilized both door-to-door (DtD) and central point (CP) vaccination methods. Surveys collected information on preferences for rabies vaccine delivery and were administered in Amharic. A total of 1057 surveys were completed. Of those surveyed, 62.4 % indicated that their dogs had been vaccinated against rabies within the last year. Commonly reported barriers to vaccination were a lack of awareness that dogs required rabies vaccines (18.1 %) and lack of knowledge about where to find vaccine (15.0 %). The median price owners were willing to pay for vaccination was 25 birr ($0.91 USD) and the median distance willing to travel was 1.0 km; however, 48.9 % of those surveyed during DtD were unwilling to travel at all. We identified 3 classes of respondents who were grouped due to their responses by latent class analysis: 'the Unaware', 'the Vaccinators', and 'the Multiple Barriers'. CONCLUSIONS/SIGNIFICANCE: Although many respondents were willing to pay for rabies vaccine (94.0 %); the preferred cost (median) was less than the actual cost of providing the vaccine. This supports the need for reduced-cost or free vaccine to achieve and sustain the 70 % vaccine coverage target threshold for canine rabies elimination. Additionally, a significant portion (41.5 %) of those surveyed indicated that they were unwilling to travel in order to have their dog vaccinated. The latent class analysis provides useful guidance on how to reach target vaccination. Owners from 'the Unaware' group made up 18.1 % of respondents and their high rate of allowing their dogs to roam identifies them as a prime target for canine health and behavior education. 'The Multiple Barriers' owners reported lower degrees of dog roaming and were substantially more likely to be found by DtD campaigns, possibly because they have limited ability/interest in handling their dogs. These results demonstrate the importance of incorporating DtD vaccination as well as subsidies to maximize vaccine coverage in Addis Ababa.

Use of partial N-gene sequences as a tool to monitor progress on rabies control and elimination efforts in Ethiopia.

Ethiopia is one of the African countries most affected by rabies. A coarse catalog of rabies viruses (RABV) was created as a benchmark to assess the impact of control and elimination activities. We evaluated a 726 bp amplicon at the end of the N-gene to infer viral lineages in circulation using maximum likelihood and Bayesian methods for phylogenetic reconstruction. We sequenced 228 brain samples from wild and domestic animals collected in five Ethiopian regions during 2010-2017. Results identified co-circulating RABV lineages that are causing recurrent spillover infections into wildlife and domestic animals. We found no evidence of importation of RABVs from other African countries or vaccine-induced cases in the area studied. A divergent RABV lineage might be involved in an independent rabies cycle in jackals. This investigation provides a feasible approach to assess rabies control and elimination efforts in resource-limited countries.

General public health considerations for responding to animal hoarding cases.

Animal hoarding is an under-recognized problem that exists in most communities and adversely impacts the health, welfare, and safety of humans, animals, and the environment. These guidelines address public health and worker safety concerns in handling situations where animal hoarding or other dense concentrations of animals have caused unhealthy and unsafe conditions. Because animal hoarding situations are often complex, a full response is likely to be prolonged and require a cross-jurisdictional multiagency effort. Each animal hoarding case has unique circumstances related to the types and numbers of animals involved, the physical structure(s) where they are being kept, and the health status of the animals, among other factors that must be taken into account in planning a response. Some general public health considerations and associated recommendations for personal protective equipment use are presented that apply to all cases, however.

Policy Perspectives of Dog-Mediated Rabies Control in Resource-Limited Countries: The Ethiopian Situation.

One Health disease-control programs are believed to be most effective when implemented within the population transmitting the disease. The World Health Organization (WHO) and partners have targeted the elimination of dog-mediated human rabies by 2030 primarily through mass dog vaccination. Mass vaccination, however, has been constrained by financial resource limitations. The current owner-charged dog vaccination strategy, used in most resource-limited countries like Ethiopia, has not reached the minimum coverage required to build population immunity. Dog vaccination is non-existing in most rural areas of Ethiopia, and coverage is <20% in urban areas. Although the health and economic benefits of rabies elimination outweigh the costs, the direct beneficiaries (public in general) and those who bear the costs (dog owners) are not necessarily the same. In this perspective paper, we aggregate evidence on the socioeconomic burden of rabies in Ethiopia as well as the implications for potential opportunities to control the disease and possibilities to obtain the required funding sources for evidence-based interventions in the control of rabies in Ethiopia.

Using a Staff Survey to Customize Burnout and Compassion Fatigue Mitigation Recommendations in a Lab Animal Facility.

Working with research animals exposes employees to emotionally demanding work and moral stressors. The emotional impact of animal research is similar to that of working with human patients, and is similarly associated with burnout (BNO) or compassion fatigue (CF), which can lead to psychosomatic symptoms, pervasive states of stress, workplace conflict, and at its most extreme, suicidal ideation. One remedy for such feelings is increasing the satisfaction one feels from performing one's job well, known as compassion satisfaction (Csat). To address these occupational health concerns in an academic research setting, the Ohio State University's Lab Animal Resources (ULAR) study team reviewed existing preventative programing both internal and external to the university. Subsequently, a survey was distributed to all staff members to assess the following factors: employee awareness of free resources already available to them, association between staff demographics and the experience of BNO and/or CF, and the employee's own mitigation recommendations. Respondents were mostly female, in 20 to 49 age range, with 0 to 4 y in the field. Of those responding, 81.6% specified that they had experienced BNO and CF alone, together, or in combination with CSat. Factors statistically associated (P < 0.05) with BNO and CF were age, number of years in the field, and number of animals euthanized per year. A relative risk analysis was also used to identify protective factors. Only the age of respondents appeared to be a protective factor- the 50+ age group had 88.57% (RR = 0.1143) reduction in risk for experiencing BNO and/or CF. Participant suggestions indicated that employees would like improvements to the work environment, more novel work experiences, and more positive feedback from department leadership. The social ecological model, a public health model for program interventions, was used as a framework for the development of recommendations to mitigate BNO and CF while increasing CSat. The recommendations were customized for ULAR employees based on the survey findings.

Comparison of field surveillance methods for and assessment of factors potentially associated with the presence of free-roaming cats in a mixed-urban environment.

OBJECTIVE To evaluate 2 methods of surveying free-roaming cats (Felis catus) and identify factors potentially associated with the presence of such cats in a mixed-urban environment. ANIMALS Free-roaming cats on and near The Ohio State University campus. PROCEDURES The university campus and surrounding areas were divided into zones classified by land-use category; 100 zones were selected for surveillance of free-roaming cats by the line-transect method (with visual observation). Twenty-three of the 100 zones were selected for surveillance by the trail-camera method (motion-triggered still photography). Food resources in the study site were mapped, and the presence of other animal species was recorded with trail cameras. Potential associations between the number of cat sightings and variables of interest were assessed by statistical methods, RESULTS There were 6 cat sightings in 5 zones and 92 cat sightings in 9 zones with the line-transect and trail-camera methods, respectively. Cats were most frequently detected off campus and in urban land-use zones. The number of cat sightings with trail cameras was significantly correlated with the density of food resources but not wildlife sightings in the area and was significantly greater at night than during the day. CONCLUSIONS AND CLINICAL RELEVANCE The number of sightings with the trail-camera method was substantially higher than that obtained with the line-transect method; however, identification of individual cats was generally not possible, and population size could not be estimated with these methods. Communities considering population control for free-roaming cats should consider the use of trail cameras to identify areas with high free-roaming cat activity and observation at night to gather baseline data. Easily accessible food waste may attract free-roaming cats.

Impact of heat treatment on Dirofilaria immitis antigen detection in shelter dogs.

BACKGROUND: The diagnosis and management of canine heartworm disease is a growing concern for shelter veterinarians. Although the accuracy of commercial antigen test kits has been widely studied, recent reports have renewed interest in antigen blocking as a causative factor for false "no antigen detected" results. The objectives of this study were to determine the prevalence of false "no antigen detected" results in adult dogs entering shelters in northern, southern, and western regions of the country and to identify historical and clinical risk factors for such results. METHODS: Serum samples were evaluated for Dirofilaria immitis antigen using a commercially available point-of-care ELISA; samples in which no antigen was detected underwent a heat treatment protocol and repeat antigen testing. Whole blood samples underwent Knott testing to identify the presence of microfilariae. Historical and clinical findings were analyzed using exact logistic regression. RESULTS: A total of 616 samples were analyzed. Overall prevalence of positive antigen test results (prior to heat treatment) was 7.3% and frequency of false "no antigen detected" results due to antigen blocking (ie, samples with no antigen detected prior to heat treatment and positive after heat treatment) was 5.2%. Among dogs that had no detectable antigen on the initial tests, dogs that had microfilariae detected via modified Knott testing (OR = 32.30, p-value = 0.013) and dogs that previously received a heartworm preventive (OR = 3.81, p-value = 0.016) had greater odds of antigen blocking than dogs without these factors. Among dogs that were heartworm positive, those without microfilariae detected had greater odds of antigen blocking than dogs with this factor (OR = 11.84, p-value = 0.0005). Geographic region of origin was significantly associated with occurrence of antigen blocking (p = 0.0036); however, blocking occurred in all regions sizably contributing to heartworm diagnoses. Of the 74 dogs found to be infected with heartworms in this study, 39.2% (29) had no detectable antigen prior to heat treatment. CONCLUSIONS: Heat treatment of serum samples should be considered to improve diagnostic test accuracy, particularly in dogs that reportedly received a heartworm preventive prior to antigen testing regardless of region of origin.

Costs of raccoon rabies incidents in cattle herds in Hampshire County, West Virginia, and Guernsey County, Ohio.

OBJECTIVE: To determine direct and indirect costs associated with raccoon rabies incidents involving cattle herds in Hampshire County, WV, in 2008 and Guernsey County, Ohio, in 2010. DESIGN: Ex post cost analysis. ANIMALS: 1 cattle herd in Hampshire County, WV, in 2008 and 1 cattle herd in Guernsey County, Ohio, in 2010. PROCEDURES: Data were collected for each incident through telephone and email interviews with 16 federal, state, and county agency personnel involved in the case investigations and coordinated responses for rabies in the cattle herds. To characterize the economic impact associated with rabies in the 2 cattle herds, cost analysis was conducted with 7 cost variables (salary and benefits for personnel involved in the response, human postexposure prophylaxis, indirect patient costs, rabies diagnostic testing, cattle carcass disposal, market value of euthanized cattle, and enhanced rabies surveillance). Estimates of direct costs were determined on the basis of agency records and other relevant data obtained from notes and reports made by agency staff at the time of the incident and from a review of the literature. RESULTS: Primary costs included the market value of euthanized cattle ($51,461 in West Virginia; $12,561 in Ohio), human postexposure prophylaxis ($17,959 in West Virginia; $11,297 in Ohio), and salary and benefits for personnel involved in the response ($19,792 in West Virginia; $14,496 in Ohio). CONCLUSIONS AND CLINICAL RELEVANCE: These results should provide a basis for better characterization of the economic impact of wildlife rabies in cattle in the United States.
