RESUMEN

Rabies has rarely been described in Xenarthra, and rabies vaccine response has not been documented. A southern tamandua (Tamandua tetradactyla) presented with nonspecific clinical signs and was euthanatized. Subsequently, immunohistochemistry and RT-PCR confirmed a rabies diagnosis. Following these tests, a group of eight captive tamanduas were vaccinated with a killed rabies vaccine, and titers were measured at the time of vaccination and 23 d later. One animal had day 0 titers suggestive of previous vaccination or exposure. All animals had detectable neutralizing rabies virus antibody titers after vaccination, but one animal failed to meet the World Organization for Animal Health's definition for adequate vaccination (≥0.5 IU/ml), and two other animals had low antibody titers (0.56 and 0.6 IU/ml). Rabies should be considered as a possible cause of illness in tamanduas, and rabies vaccination may be a useful preventative measure when anthropic interaction through medical care or ambassador roles is occurring.

RESUMEN

On August 16, 2021, the Tennessee Department of Health (TDH) was notified of a positive rabies test result from a South American collared anteater (Tamandua tetradactyla) in Washington County, Tennessee. Tamanduas, or lesser anteaters, are a species of anteater in which rabies has not previously been reported. The animal was living at a Tennessee zoo and had been recently translocated from a zoo in Virginia. TDH conducted an investigation to confirm the rabies result, characterize the rabies variant, and ascertain an exposure risk assessment among persons who came into contact with the tamandua. Risk assessments for 22 persons were completed to determine the need for rabies postexposure prophylaxis (rPEP); rPEP was recommended for 13 persons, all of whom agreed to receive it. Using phylogenetic results of the virus isolated from the tamandua and knowledge of rabies epidemiology, public health officials determined that the animal was likely exposed to wild raccoons present at the Virginia zoo. This report describes expansion of the wide mammalian species diversity susceptible to rabies virus infection and summarizes the investigation, highlighting coordination among veterinary and human public health partners and the importance of preexposure rabies vaccination for animal handlers and exotic zoo animals.

RESUMEN

Backyard poultry are commonly treated in veterinary hospitals; however, there is limited information regarding appropriate dosing of medications and withdrawal times for eggs. Six healthy adult bantam Cochin hens were given a single oral dose of meloxicam (1 mg/kg). Meloxicam plasma concentrations and egg residues were analyzed by high-performance liquid chromatography. Noncompartmental analysis was used to calculate pharmacokinetic parameters. The apparent terminal half-life, maximum concentration, and time to maximum concentration were 5.94 ± 0.92 hours, 7.03 ± 2.68 µg/mL, and 2.83 ± 1.33 hours, respectively. Meloxicam was detected in egg whites for 4.8 ± 1.5 days and egg yolks for 9.8 ± 2.4 days. Results were compared with previous studies in white leghorn and Columbian Wyandotte hens. Bantam Cochin hens demonstrated a significantly longer mean apparent terminal half-life, greater area under the curve, smaller elimination rate constant, and longer egg residue times compared with white leghorn hens. However, the pharmacokinetic results from the bantam Cochin hens did not significantly differ from those reported for the Columbian Wyandotte hens. Until pharmacodynamic studies can be performed, dosing of oral meloxicam in bantam Cochins should follow recommendations for Columbian Wyandotte hens to reduce the likelihood of adverse effects. These results better inform appropriate dosing of meloxicam in domestic hens, as well as recommended withdrawal times for egg consumption.

RESUMEN

Batrachochytrium dendrobatidis (Bd) is an important fungal pathogen present in wild hellbender (Cryptobranchus alleganiensis) populations that appears to cause disease during novel exposure and acute stress. Hellbender repatriation efforts are ongoing to combat declining populations, but mortality by chytridiomycosis (disease from Bd) after release has been reported. The goal was to determine whether a safe antifungal agent could be administered and provide prolonged plasma concentrations without repeated handling. A subcutaneous implant impregnated with 24.5 mg of terbinafine was tested in three juvenile eastern hellbenders (C. a. alleganiensis) raised in human care, and plasma terbinafine concentrations were recorded from weekly to biweekly for 141 days. Plasma concentrations were variable, with peak plasma concentrations of 1,610, 112, and 66 ng/ml between 28 and 56 days postimplant. Although all hellbenders achieved plasma concentrations above the published minimum inhibitory concentration for terbinafine against Bd zoospores (63 ng/ml) at several time points, only one individual remained above this threshold for more than two consecutive time intervals. Results show the potential for these implants as a prophylaxis for chytridiomycosis in captive-to-wild hellbender releases. However, further investigation will be needed to determine the plasma concentrations required to achieve prophylaxis in vivo and implant reliability.

RESUMEN

This study examined the pharmacokinetics of orally administered amoxicillin and clavulanic acid tablets (Clavamox, 125 mg/kg PO q12h for 9 doses) in domestic hens and examined both amoxicillin and clavulanic acid concentrations in eggs. Therapeutic plasma concentrations (0.5 µg/mL) of amoxicillin were not reached at any time point, and no amoxicillin was detected in plasma after 2 hours. Pharmacokinetic parameters could not be calculated. The clavulanic acid half-life was 1.1 hours and it was detected up to 8 hours after dosing. No amoxicillin was detected in eggs 4 days postdosing, nor was clavulanic acid detected in any eggs during the same time period. On the basis of these results, orally dosing hens with amoxicillin and clavulanic acid tablets at 125 mg/kg PO q12h does not reach therapeutic plasma concentrations. Additional studies are needed to examine different doses and formulations of medication to determine better dosing and withdrawal recommendations for domestic chickens.

RESUMEN

With increased ownership of backyard poultry, veterinarians must treat these birds appropriately and take into consideration drug withdrawal times for eggs meant for consumption. Few studies have examined the pharmacokinetics or egg residues for medications commonly used in avian medicine. This study determined the pharmacokinetics of meloxicam in domestic chickens (n = 8) after oral dosing at 1 mg/kg q12h for a total of 9 doses (5 days). Additionally, the presence of meloxicam residues in eggs was determined. The terminal half-life, maximum concentration, and time to maximum concentration were 3.02 ± 1.15 hours, 7.14 ± 1.54 µg/mL, and 1.6 ± 0.52 hours, respectively. No drug was detected in yolks and whites after 8 days and 3 days, respectively. On the basis of these results, a 2-week withdrawal time should be adequate to avoid drug residues in eggs meant for consumption.

RESUMEN

Aspergillosis is a common fungal infection in both wild and pet birds. Although effective antifungal medications are available, treatment of aspergillosis can require months of medication administration, which entails stressful handling one or more times per day. This study examined the delivery of the antifungal drugs itraconazole, voriconazole, and terbinafine to Japanese quail ( Coturnix japonica ) via an impregnated implant. Implants contained 0.5, 3, 8, or 24 mg of itraconazole, voriconazole, or terbinafine. The implants were administered subcutaneously over the dorsum and between the scapulae. Blood was collected from birds before and 2, 7, 21, 42, and 56 days after implant placement. Plasma was analyzed by high-performance liquid chromatography for concentrations of itraconazole, voriconazole, or terbinafine, as appropriate. During the course of the study, targeted terbinafine concentrations were achieved in some birds at various time points, but concentrations were inconsistent. Itraconazole and voriconazole concentrations were also inconsistent and did not reach targeted concentrations. Currently, the implant examined in this study cannot be recommended for treatment of aspergillosis in avian species.

RESUMEN

The efficacy and safety of topically applied rocuronium in Hispaniolan Amazon parrots ( Amazona ventralis ) was assessed in a group of 10 adult birds. A complete ophthalmic examination (including Schirmer tear test, ocular reflexes, applanation tonometry, fluorescein staining, and slit-lamp biomicroscopy) was performed, and rocuronium bromide (0.15 mg in both eyes) was administered. Pupillary light reflex (PLR) and pupillary diameter were recorded in a darkened room at the following time points: 0, 10, 20, 30, 40, 50, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, 300, and 360 minutes, and 24 hours. Fluorescein staining in both eyes was performed at 24 hours. By 10 minutes, PLR was absent in all birds (at 5 minutes, 8 birds; at 10 minutes, remaining 2 birds). Pupil diameter differed significantly from baseline at all time points. Additionally, PLR was decreased in 7/10 birds at 360 minutes and normal in all birds at 24 hours. Superficial corneal ulceration was observed at 24 hours in the left eye of 2/10 of the birds after fluorescein stain application. This study demonstrated that rocuronium bromide was an effective mydriatic agent in Hispaniolan Amazon parrots with rapid onset and prolonged duration of action.

RESUMEN

Use of disinfectants by biologists, veterinarians, and zoological facilities is a standard biosecurity procedure to prevent contamination and the spread of pathogens. We tested the efficacy of 5 disinfectants and 1 anti-fungal treatment, at 1 and 5 min contact durations, in inactivating Batrachochytrium dendrobatidis (Bd) grown on tryptone media. Our study focused on concentrations of disinfectants known to inactivate ranaviruses, which can be found at the same sites as Bd and can concurrently infect amphibians. Disinfectants tested were chlorhexidine gluconate (0.25, 0.75, and 2%), Pro-San (0.19, 0.35, and 0.47%), Virkon S (1%), household bleach (0.2, 1, and 3%), and Xtreme Mic (5%). The anti-fungal was terbinafine HCl at 0.005, 0.05, 0.1, and 1 mg ml-1. Inactivation of Bd was determined by microscopic evaluation of zoospore motility and growth of colony mass after 14 d. All disinfectants were effective at inactivating zoospore motility and colony growth of Bd at all concentrations and both contact times; however, terbinafine HCl inactivated Bd at only the highest concentration tested (1 mg ml-1) and 5 min duration. Thus, a minimum of 0.25% chlorhexidine gluconate, 0.19% Pro-San, 1% Virkon, 0.2% bleach, and 5% Xtreme Mic with 1 min contact was sufficient to inactivate Bd. Also, terbinafine HCl (1 mg ml-1) with a 5 min contact time might be effective in treating amphibians infected with Bd. Based on this study and previously published findings, 0.75% Nolvasan, 1% Virkon S, and 3% bleach with 1 min contact are sufficient to inactivate both Bd and ranaviruses.

RESUMEN

Approximately 5.4 million cubic yards of coal fly ash and water spilled into the Emory River embayment of Watts Bar Reservoir in east Tennessee on Dec 22, 2008. Raccoons were collected in 2009 and 2010 from the spill site (10/y) and unexposed areas (5/y) to determine whether metals and metalloids were accumulating in raccoons and if any negative health effects resulted from exposure to the spilled coal fly ash. Tissues were analyzed from each animal to determine the concentrations of 26 metals/metalloids. Complete blood cell counts (CBC), plasma biochemistry panels, and histopathology of select tissues also were performed. Results were analyzed by year and exposure status. Although significant differences were present in some tissues for some metals/metalloids, only arsenic in hair, iron in muscle, nickel in hair, selenium in hair and muscle, strontium in hair, and vanadium in hair and liver were increased in spill site animals (one or both years) compared with unexposed animals. No clinically important differences were observed between groups regarding CBC or plasma biochemistry analyses. Lesions were observed on histopathology in some tissues, but there was no difference in the prevalence of lesions between spill site and unexposed animals. There does not seem to be any important accumulation of metals/metalloids or negative health effects in raccoons associated with exposure to coal fly ash compared with unexposed animals.

RESUMEN

A captive, 9-yr-old castrated male tiger (Panthera tigris) from an exotic cat sanctuary and rescue facility was observed to have three collapsing episodes within a 2-wk interval prior to being examined by veterinarians. No improvement in clinical signs was noted after empiric treatment with phenobarbital. During a more complete workup for epilepsy, ventricular flutter was observed on electrocardiogram (ECG). The arrhythmia resolved with a single intravenous bolus of lidocaine. Cardiac structure and function were unremarkable on echocardiogram and cardiac troponin I levels were within normal limits for domestic felids. No significant abnormalities were noted on abdominal ultrasound. Complete blood count and biochemistry panel were unremarkable, and heartworm antigen and Blastomyces urine antigen enzyme-linked immunosorbent assays were negative. Antiarrhythmic treatment with sotalol was initiated. On follow-up ECG performed 1 mo later, no significant arrhythmias were noted, and clinical signs have completely resolved.

RESUMEN

Foods that contain antibiotic residues have potential adverse health effects on consumers and provide selective pressure for the threat of antimicrobial resistance (AMR). This study's objective was to measure tetracycline, sulfonamide, and erythromycin residues in beef, eggs, and honey sold as "antibiotic-free" at farmers' markets in East Tennessee (East TN) in the United States (U.S.). Between July and September 2020, 36 "antibiotic-free" food products (9 beef, 18 egg, and 9 honey products) were purchased from East TN farmers' markets and tested for tetracycline, sulfonamide, and erythromycin residues using competitive enzyme-linked immunosorbent assays (cELISA). All beef, egg, and honey products had tetracycline residue; the median concentrations were 51.75, 30.25, and 77.86 µg/kg, respectively. Sulfonamide residue was present in every sample of beef. Of 18 eggs, 11 eggs had detectable sulfonamide residue; the median concentrations were 3.50 and 1.22 µg/kg in beef and eggs, respectively. Each sample of beef and honey contained erythromycin residue; the median concentrations were 3.67 and 0.68 µg/kg, respectively. Overall, the median concentrations of tetracycline, sulfonamide, and erythromycin residues were below the maximum residue levels (MRLs) set in the U.S. for beef and eggs. Thus, the beef and eggs sold as "antibiotic-free" in East TN farmers' markets can be considered safe for consumption. Safety determination for honey could not be made because MRLs have not been set for honey in the U.S. Because these residues should not be expected in "antibiotic-free" food products, it is important to further investigate the potential sources of these residues in these products.

RESUMEN

With the declaration of the COVID-19 pandemic by the World Health Organization on March 11, 2020, the University of Tennessee College of Veterinary Medicine (UTCVM), like other institutions, restructured their services to reduce the potential spread of the COVID-19 virus while simultaneously providing critical and essential veterinary services. A mathematical model was developed to predict the change in the level of possible COVID-19 infections due to the increased number of potential contacts within the UTCVM hospital. A system of ordinary differential equations with different compartments for UTCVM individuals and the Knox county population was formulated to show the dynamics of transmission and the number of confirmed cases. Key transmission rates in the model were estimated using COVID-19 case data from the surrounding county and UTCVM personnel. Simulations from this model show the increasing number of COVID-19 cases among UTCVM personnel as the number of daily clients and the number of veterinary staff in the clinic are increased. We also investigate how changes within the Knox county community impact the UTCVM hospital. These scenarios show the importance of understanding the effects of re-opening scenarios in veterinary teaching hospitals.

RESUMEN

Aspergillosis is one of the most difficult diseases to treat successfully in avian species. Terbinafine hydrochloride offers numerous potential benefits over traditionally used antifungals for treatment of this disease. Adding nebulized antifungals to treatment strategies is thought to improve clinical outcomes in lung diseases. To determine plasma concentrations of terbinafine after nebulization, 6 adult Hispaniolan Amazon parrots were randomly divided into 2 groups of 3. Each bird was nebulized for 15 minutes with 1 of 2 terbinafine solutions, one made with a crushed tablet and the second with raw drug powder. Blood samples were collected at baseline and at multiple time points up to 720 minutes after completing nebulization. Plasma and nebulization solutions were analyzed by high-performance liquid chromatography. The terbinafine concentration of the solution made with a crushed tablet (0.87 +/- 0.05 mg/mL) was significantly lower than was that made with raw powder (1.02 +/- 0.09 mg/mL). Plasma concentrations of terbinafine did not differ significantly between birds in the 2 groups. Plasma terbinafine concentrations in birds were maintained above in vitro minimum inhibitory concentrations for approximately 1 hour in birds nebulized with the crushed tablet solution and 4 hours in birds nebulized with the raw powder solution. Higher concentrations of solution, longer nebulization periods, or more frequent administration are likely needed to reach therapeutic plasma concentrations of terbinafine for clinically relevant periods in Hispaniolan Amazon parrots.

RESUMEN

A teaching workshop was delivered for faculty members of East African colleges of veterinary medicine to foster teaching development and reflection. The goal was for participants to use knowledge gained to improve teaching skills. The approach was to "train the trainer" so attendees could transfer new knowledge to colleagues at their institutions. Techniques were used to increase the likelihood that participants would apply the training. A culturally responsive survey was developed to assess training transfer 1 year later. Pilot survey results suggest that participants applied what they learned and shared with colleagues largely due to peer and supervisor support. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1007/s40670-021-01428-2.

RESUMEN

Pet ownership, the most common human-animal interaction, is believed to bestow positive health benefits onto pet owners. However, there is limited research on substantiating these assertions. The aim of this review was to systematically identify, evaluate, and summarize primary research on the relationship between cat and/or dog ownership and cardiovascular disease (CVD), type 2 diabetes (T2D), and obesity to inform future research on pet ownership and chronic disease. How pet ownership was defined/measured, and identification of the chronic disease variables and health behaviors most often measured were emphasized. Two researchers independently searched PubMed and Web of Science, where One Health literature are mostly likely to be indexed, for peer-reviewed literature on pet ownership and CVD, T2D, and obesity. A review of 4541 titles and abstracts for relevance resulted in 34 manuscripts eligible for full-text review. Two researchers assessed each eligible manuscript and extracted data only from those that met the inclusion criteria (n = 14). Ten studies on CVD, four studies on obesity, and zero studies on T2D met the study criteria. The CVD and obesity variables varied and were not well described. The relationship between pet ownership and CVD and obesity varied (positive, negative, mixed effects, and no effect). Generalizability lacked across all studies: most studies were with Non-Hispanic White populations. Other areas of weakness were quality of study outcomes and instrument validity. Operationalization of pet ownership varied (from no verification to confirmed pet registration). Integration of the evidence-based influence of the human-animal connection through pet ownership on CVD and obesity may make prevention, mitigation, and treatment strategies more robust.

RESUMEN

Bushmeat hunting and consumption, although widely utilized as necessary supplement to household income and nutrition in many regions, presents threats to public health and wildlife conservation efforts. In northern Uganda, consumption of bats and primates, two wildlife groups often implicated in zoonotic disease emergence, is not widely culturally accepted; however, these species are reported by hunters to often be hunted and sold as culturally desirable species, like antelope and warthog. To investigate the prevalence of market bushmeat misidentifiction, we collected 229 bushmeat samples from 23 communities adjacent to Murchison Falls National Park. Reported species was recorded on acquisition for each sample. PCR targeting mammalian cyt b and 12 s rRNA genes and sequencing were performed to identify samples to the lowest taxonomic unit using NCBI BLAST. Overall, 27.9% (61/219) of samples had disparate results between species reported and BLAST analysis. Thirty-four species were identified, with the most frequent wildlife being waterbuck (31.5%), warthog (13.7%), and black rat (5.9%). These data reveal a public health risk for bushmeat consumers in northern Uganda as they cannot assess species-related risk when purchasing bushmeat and take appropriate precautions against zoonotic pathogen exposure. These data also provide insight into regional hunter prey preference and market preference of local community members which may inform conservation strategy in the region.

RESUMEN

OBJECTIVE: To determine the pharmacokinetics of meloxicam in Wyandotte hens and duration and quantity of drug residues in their eggs following PO administration of a single dose (1 mg of meloxicam/kg [0.45 mg of meloxicam/lb]) and compare results with those previously published for White Leghorn hens. ANIMALS: 8 healthy adult Wyandotte hens. PROCEDURES: Hens were administered 1 mg of meloxicam/kg, PO, once. A blood sample was collected immediately before and at intervals up to 48 hours after drug administration. The hens' eggs were collected for 3 weeks after drug administration. Samples of the hens' plasma and egg whites (albumen) and yolks were analyzed with high-performance liquid chromatography. RESULTS: Mean ± SD terminal half-life, maximum concentration, and time to maximum concentration were 5.53 ± 1.37 hours, 6.25 ± 1.53 µg/mL, and 3.25 ± 2.12 hours, respectively. Mean ± SD number of days meloxicam was detected in egg whites and yolks after drug administration was 4.25 ± 2 days and 9.0 ± 1.5 days, respectively. CONCLUSIONS AND CLINICAL RELEVANCE: Compared with White Leghorn hens, meloxicam in Wyandotte hens had a longer terminal half-life, greater area under the plasma concentration-versus-time curve from time 0 to infinity, a smaller elimination rate constant, and a longer mean residence time-versus-time curve from time 0 to infinity, and drug persisted longer in their egg yolks. Therefore, the oral dosing interval of meloxicam may be greater for Wyandotte hens. Results may aid veterinarians on appropriate dosing of meloxicam to Wyandotte hens and inform regulatory agencies on appropriate withdrawal times.

RESUMEN

Pet ownership is the most common form of human-animal interaction, and anecdotally, pet ownership can lead to improved physical and mental health for owners. However, scant research is available validating these claims. This study aimed to review the recent peer reviewed literature to better describe the body of knowledge surrounding the relationship between pet ownership and mental health. A literature search was conducted in May 2020 using two databases to identify articles that met inclusion/exclusion criteria. After title review, abstract review, and then full article review, 54 articles were included in the final analysis. Of the 54 studies, 18 were conducted in the general population, 15 were conducted in an older adult population, eight were conducted in children and adolescents, nine focused on people with chronic disease, and four examined a specific unique population. Forty-one of the studies were cross-sectional, 11 were prospective longitudinal cohorts, and two were other study designs. For each of the articles, the impact of pet ownership on the mental health of owners was divided into four categories: positive impact (n = 17), mixed impact (n = 19), no impact (n = 13), and negative impact (n = 5). Among the reviewed articles, there was much variation in population studied and study design, and these differences make direct comparison challenging. However, when focusing on the impact of pet ownership on mental health, the results were variable and not wholly supportive of the benefit of pets on mental health. Future research should use more consistent methods across broader populations and the development of a pet-ownership survey module for use in broad, population surveys would afford a better description of the true relationship of pet ownership and mental health.

RESUMEN

The harvest of bushmeat is widespread in the tropics and sub-tropics. Often in these communities, there is a dependence on bushmeat for both food security and basic income. Despite the importance of bushmeat for households worldwide, the practice raises concern for transmission of zoonotic pathogens through hunting, food preparation, and consumption. In Uganda, harvest of wildlife is illegal, but bushmeat hunting, is commonplace. We interviewed 292 women who cook for their households and 180 self-identified hunters from 21 villages bordering Murchison Falls National Park in Uganda to gain insights into bushmeat preferences, opportunity for zoonotic pathogen transmission, and awareness of common wildlife-associated zoonoses. Both hunters and women who cook considered primates to be the most likely wildlife species to carry diseases humans can catch. Among common zoonotic pathogens, the greatest proportions of women who cook and hunters believed that pathogens causing stomach ache or diarrhea and monkeypox can be transmitted by wildlife. Neither women who cook nor hunters report being frequently injury during cooking, butchering, or hunting, and few report taking precautions while handling bushmeat. The majority of women who cook believe that hunters and dealers never or rarely disguise primate meat as another kind of meat in market, while the majority of hunters report that they usually disguise primate meat as another kind of meat. These data play a crucial role in our understanding of potential for exposure to and infection with zoonotic pathogens in the bushmeat trade. Expanding our knowledge of awareness, perceptions and risks enables us to identify opportunities to mitigate infections and injury risk and promote safe handling practices.
