RESUMEN

Objective: To visually evaluate and morphometrically describe a sample of abnormal hooves from Sable Island horses that died between 2007 and 2013. Animal: Equine. Procedure: An opportunistic sample of 356 abnormal hooves from horses inhabiting Sable Island National Park Reserve (Canada) was collected postmortem between 2007 and 2013 from 101 Sable Island horses. These hooves were assessed for abnormalities in conformation through visual and morphometric evaluation. Results: On visual and morphometric evaluation, 100% of horses (101/101) had abnormal hoof conformation when compared to a domestic horse hoof model. Specific abnormalities from visual evaluation included long heels (85%); medial, lateral, and dorsal flares (45, 78, and 46% of horses, respectively); and cracking (62%). Specific abnormalities determined from morphometry of the hooves included contracted heels (87%), hoof imbalances including mediolateral imbalance (61%), and hoof length greater than width (100%). Conclusion: Sable Island horses had various hoof abnormalities such as hoof capsule flaring; long, contracted heels; and mediolateral imbalance. These abnormalities have been observed in other feral horse populations living on soft substrates. Given the potential impact of hoof abnormalities on the welfare status of the Sable Island horses, further studies are warranted, including estimation of the prevalence of hoof abnormalities and direct observation of horse gait and behavior. Clinical relevance: The significance of the hoof abnormalities for the health of the Sable Island horses is difficult to determine but the issue highlights the importance of further study to investigate the impact on the horses' welfare.


Description visuelle et morphométrique des sabots de chevaux sauvages de la réserve de parc national de l'Île-de-Sable. Objectif: Évaluer visuellement et décrire morphométriquement un échantillon de sabots anormaux de chevaux de l'île de Sable décédés entre 2007 et 2013. Animal: Cheval. Procédure: Un échantillon opportuniste de 356 sabots anormaux provenant de chevaux habitant la réserve de parc national de l'Île-de-Sable (Canada) a été prélevé post-mortem entre 2007 et 2013 sur 101 chevaux de l'île-de-Sable. Ces sabots ont été évalués pour déceler des anomalies de conformation par une évaluation visuelle et morphométrique. Résultats: Lors de l'évaluation visuelle et morphométrique, 100 % des chevaux (101/101) présentaient une conformation de sabot anormale par rapport à un modèle de sabot de cheval domestique. Les anomalies spécifiques de l'évaluation visuelle comprenaient les talons longs (85 %); poussées médiales, latérales et dorsales (respectivement 45, 78 et 46 % des chevaux); et fissuration (62 %). Les anomalies spécifiques déterminées à partir de la morphométrie des sabots comprenaient des talons contractés (87 %), des déséquilibres des sabots, notamment un déséquilibre médiolatéral (61 %) et une longueur du sabot supérieure à la largeur (100 %). Conclusion: Les chevaux de l'île-de-Sable présentaient diverses anomalies aux sabots, telles qu'un évasement de la boîte cornée; talons longs et contractés; et déséquilibre médiolatéral. Ces anomalies ont été observées chez d'autres populations de chevaux sauvages vivant sur des substrats mous. Compte tenu de l'impact potentiel des anomalies des sabots sur le bien-être des chevaux de l'Île-de-Sable, d'autres études sont justifiées, notamment l'estimation de la prévalence des anomalies des sabots et l'observation directe de la démarche et du comportement des chevaux. Pertinence clinique: L'importance des anomalies des sabots pour la santé des chevaux de l'Île-de-Sable est difficile à déterminer, mais la question souligne l'importance d'une étude plus approfondie pour étudier l'impact sur le bien-être des chevaux.(Traduit par Dr Serge Messier).

RESUMEN

BACKGROUND: Cellular deterioration occurs with blood sample aging, impacting white blood cell (WBC) identification and differential accuracy. This may be exacerbated in samples from patients experiencing inflammation. Previously, bovine serum albumin (BSA) has been shown to improve cellular preservation of blood and other samples, but the effect on cell preservation in canine blood has not been assessed. OBJECTIVES: We aimed to determine the effects of BSA on neutrophil nuclear area when added to potassium ethylene diamine tetra-acetic acid (K3 -EDTA)-anticoagulated canine blood prior to blood smear preparation. We evaluated the impact of inflammatory leukograms, sample storage temperatures (4° and 20°C), and time on outcomes. MATERIALS AND METHODS: Canine K3 -EDTA-anticoagulated blood samples stored at 4° and 20°C were used from unique patients, 10 with and 10 without inflammatory leukograms. Blood smears were prepared from aliquots with or without the addition of 22% BSA at 0, 4, 8, 24, 48, and 72 h. The nuclear area was measured for 25 randomly selected neutrophils per slide using Fiji software. Mixed-effect linear regression modeling was performed (significance: P < 0.05). RESULTS: Nuclear area increased over time with and without added BSA. Both sample storage temperatures and the presence or absence of an inflammatory leukogram significantly impacted neutrophil nuclear area. Samples with added BSA had slightly higher predicted nuclear areas than those without BSA, but this difference was not statistically significant. CONCLUSIONS: BSA did not significantly impact neutrophil nuclear area and did not improve neutrophil preservation in canine blood samples.

RESUMEN

Companion animals have been shown to carry Clostridioides difficile strains that are similar or identical to strains found in people, and a small number of studies have shown that pets carry genetically identical C. difficile isolates as their owners, suggesting inter-species transmission. However, the directionality of transmission is ultimately unknown, and the frequency with which animals acquire C. difficile following their owners' infection is unclear. The goal of this study was to assess how often pets belonging to people with C. difficile infection carry genetically related C. difficile isolates. We enrolled pet owners from two medical institutions (University of Pennsylvania Health System (UPHS) and The Ohio State University Wexner Medical Center (OSUWMC)) who had diarrhoea with or without positive C. difficile assays and tested their faeces and their pets' faeces for C. difficile using both anaerobic culture and PCR assays. When microorganisms were obtained from both the owner and pet and had the same toxin profile or ribotype, isolates underwent genomic sequencing. Faecal samples were obtained from a total of 59 humans, 72 dogs and 9 cats, representing 47 complete households (i.e. where a sample was available from the owner and at least one pet). Of these, C. difficile was detected in 30 humans, 10 dogs and 0 cats. There were only two households where C. difficile was detected in both the owner and pet. In one of these households, the C. difficile isolates were of different toxin profiles/ribotypes (A+/B+ / RT 499 from the owner, A-/B- / RT PR22386 from the dog). In the other household, the isolates were genetically identical (one SNP difference). Interestingly, the dog from this household had recently received a course of antibiotics (cefpodoxime and metronidazole). Our findings suggest that inter-species transmission of C. difficile occurs infrequently in households with human C. difficile infections.

RESUMEN

The relationship between veterinary colleges (VCs), associated veterinary teaching hospital referral centers (VTHs), and referring veterinarians (rVets) is important and complex. Despite this, there has been minimal research on rVets with respect to their regional VC and VTH. Our objectives were to evaluate rVets' attitudes and self-reported needs on their regional VC's VTH surrounding (a) continuing education, (b) collaborative research, and (c) referrals for specialty consultation and care. Participants (rVets) were invited to complete an online questionnaire (2018-2019). Respondents (n = 56) indicated multiple (24) unmet continuing education topic needs, of which dermatology and behavior were most selected. Many rVets (70%) reported an interest in collaborative research participation. Communication was frequently selected by respondents when asked what could be improved with respect to the VTH referral center process. Our work provides a benchmark attitudes and needs assessment, identifies areas for improvement, and may aid initiatives regionally, and likely externally, as adapted to other rVet-VC-VTH relationships.

RESUMEN

Canine leptospirosis is an important zoonotic disease in many countries. This review examines potential drivers for increased diagnoses of canine leptospirosis in the United States and Canada, using the epidemiologic triad of agent-environment-host as a template. Leptospira spp. are classified into more than 250 serovars, but in many laboratories only 6 are routinely tested for in serologic agglutination tests of canine sera. Leptospiral infections in dogs may potentially go undetected with unemployed or currently employed diagnostic methods. Disease transmission from infected reservoir hosts usually occurs via urine-contaminated environmental sources such as water. Direct contact between infected and susceptible individuals, environmental factors such as climate changes in temperature and/or rainfall, and increasing number and urbanization of reservoir hosts may greatly increase dog exposure risks. A dog's lifestyle may influence exposure risk to leptospirosis, but vaccination based on proper identification of circulating serogroups dramatically reduces post-exposure infections. Regrettably, resistance to vaccination by veterinarians and dog owners leaves a large number of dogs at risk for this zoonotic disease.

RESUMEN

Veterinary services' rising cost is an increasing barrier to pet care. Spectrum of care (SpOC) refers to evidence-based veterinary medicine options along the socioeconomic spectrum. To meet growing pet owner financial constraints and pet care needs, training to equip veterinarians with competencies to provide SpOC as Day One graduates is argued to be added as part of the veterinary curriculum. Objectives of our prospective pre- and post-survey study were to (a) determine baseline self-reported knowledge, attitudes, and competencies (KACs) surrounding SpOC in third-year DVM students; (b) develop and assess impact of a SpOC course on student self-reported SpOC KACs; and (c) obtain student feedback on the course and future SpOC training. Enrolled students (n = 35) completed the pre-survey (n = 35) and post-survey (n = 33). Results indicated that students were aware of the need for SpOC training within the veterinary curriculum, and positive changes occurred in self-reported KAC from pre- to post-survey. Students tended (p = .08) to predict better outcomes in SpOC cost-barrier scenarios from pre- (34%) to post-survey (76%), such as reduced perceived likelihood of euthanasia (63%-39%) and unsuccessful outcomes (40%-27%). Most students (31/33, 94%) predicted the course would benefit them in clinical practice and had preferred future training preferences (online modules [70%], seminars [60%], webinars [58%]). Data indicate benefits in student self-reported KACs following the SpOC course, warranting formal course inclusion, with tracking of students into clinical practice to document objective KAC impacts and perhaps similar course rollout to other institutions.

RESUMEN

Over the past decade, there has been an apparent increased frequency and widened distribution of canine leptospirosis in Canada, however, this has been minimally investigated. Availability and clinical uptake of Leptospira polymerase chain reaction (PCR)-based testing of dogs in Canada may provide important insight into the epidemiology of this canine and zoonotic infectious disease. Study objectives were to evaluate clinical canine Leptospira PCR test results from a large commercial laboratory to determine temporal and spatial distribution in Canada and identify dog, geographic and temporal risk factors for test-positive dogs. This cross-sectional study analyzed data obtained from IDEXX Laboratories, Inc. on 10,437 canine Leptospira PCR tests (blood and/or urine) submitted by Canada-based veterinarians (July 2009 to May 2018). Multivariable logistic regression was used to identify risk factors for test-positive dogs. Test-positive proportion varied widely annually (4.8-14.0%) and by location. Provinces with the highest test-positive proportion over the study period were Nova Scotia (18.5%) and Ontario (9.6%), with the prairie provinces (Manitoba and Alberta combined) having the lowest proportion (1.0%); the northern territories could not be evaluated due to limited testing. In the final model, dog age, sex, breed, month, and year test performed, and location (urban/rural, province) of the practice submitting the sample were significant predictors of a positive Leptospira PCR test. Dogs less than one year of age (OR = 2.1; 95% CI: 1.6-2.9), male sex (OR = 1.3; 1.1-1.5), toy breed (OR = 3.3; 2.5-4.4), and samples submitted from an urban practice (OR = 1.3; 1.0-1.8) had the greatest odds of a positive Leptospira PCR test as compared to referent groups. Significant two-way interactions between province-month and year-month highlight the complex spatial and temporal influences on leptospirosis occurrence in this region. Our work suggests a high incidence of canine leptospirosis regionally within Canada. Identifiable dog and location factors may assist in future targeted prevention efforts.

RESUMEN

OBJECTIVES: The primary aims of this study were to determine preferences of North American cat owners when they are prescribed an antimicrobial for their cat with regard to cost, method of administration and the importance of antibiotics for treating infections in people, and to establish baseline knowledge, attitudes and influencers of cat owners on antimicrobial resistance and stewardship. METHODS: An online questionnaire was used for data collection from two cat-owner groups: US cat owners and Canadian cat owners. Participants were queried on antimicrobial resistance and stewardship, and their preferences for their own cat when prescribed an antimicrobial, with respect to cost, method of drug administration and the importance of a drug for treating infections in people. Responses were evaluated through conjoint analysis and Likert-type questions. Data were analyzed using descriptive and analytic statistics. RESULTS: A total of 630 complete responses were included in the final analysis. Cost (37%) and method of administration (38%) were of similar participant preference when assessed using conjoint analysis. The importance of a drug for treating infections in people was lower priority (21%). The majority of cat owners preferred an antimicrobial that was 'very important' in treating human infections. A low proportion (21%) of participants responded that antimicrobial use in pets posed a risk to humans. Participants with a university education were more likely to respond that antimicrobial use in pets was a concern for people (31%; P <0.001). CONCLUSIONS AND RELEVANCE: Cat owners prioritize antimicrobial cost and method of administration equally. Few cat owners recognized the human antimicrobial resistance risks associated with antimicrobial use in pets.

RESUMEN

OBJECTIVES: The aim of this study was to evaluate initial antimicrobial therapy in cats diagnosed with upper or lower bacterial urinary tract infections at veterinary practices in the USA and Canada. METHODS: Electronic medical records from a veterinary practice corporation with clinics in the USA and Canada were queried between 2 January 2016 and 3 December 2018. Feline patient visits with a diagnosis field entry of urinary tract infection, cystitis and pyelonephritis, as well as variation of those names and more colloquial diagnoses such as kidney and bladder infection, and where an antimicrobial was prescribed, were retrieved. RESULTS: Prescription data for 5724 visits were identified. Sporadic cystitis was the most common diagnosis (n = 5051 [88%]), with 491 (8.6%) cats diagnosed with pyelonephritis and 182 (3.2%) with chronic or recurrent cystitis. Cefovecin was the most commonly prescribed antimicrobial for all conditions, followed by amoxicillin-clavulanic acid. Significant differences in antimicrobial drug class prescribing were noted between practice types and countries, and over the 3-year study period. For sporadic cystitis, prescription of amoxicillin-clavulanic acid increased significantly and cefovecin decreased between 2016 and 2018, and 2017 and 2018, while fluoroquinolone use increased between 2017 and 2018. CONCLUSIONS AND RELEVANCE: The results indicate targets for intervention and some encouraging trends. Understanding how antimicrobials are used is a key component of antimicrobial stewardship and is required to establish benchmarks, identify areas for improvement, aid in the development of interventions and evaluate the impact of interventions or other changes.

RESUMEN

Staphylococci are inhabitants of skin and mucous membranes with Staphylococcus pseudintermedius (SP) and Staphylococcus aureus (SA) serving as important pathogens for animals and people, respectively. Previous research has identified the environment as potentially important in hospital-associated infections and zoonotic transmission in veterinary settings. The objective of this pilot study was to determine the longitudinal prevalence over repeated samplings of environmental coagulase-positive Staphylococcus (CPS) in a new veterinary hospital and evaluate associations between contamination and environmental and clinical (caseload, cleaning checklists and staff numbers) factors. Cleaning and disinfection compliance, based on staff-completed checklists, were reviewed for the three shifts immediately prior to sampling. We hypothesized that over time, environmental contamination would increase as the clinic developed and caseload increased and compliance to cleaning checklists would decrease with increasing caseload. Over 18 months, 351 environmental samples were collected at five sampling times (sampling occurred before opening the hospital and every 3 to 6 months thereafter). Overall contamination with CPS was 30.8% (108/351), with SA (16.8%) and SP (13.1%) identified from the contaminated surfaces. Overall, methicillin-resistant strains (MRSA and MRSP) were infrequently recovered (combined n = 3; <1%). Point prevalence of CPS contamination was relatively stable over the study period (22.5%-28.4%), with the exception of an increase at the fourth sampling (52.9%). Cleaning compliance varied over the study period (57.9%-100%); the lowest reported cleaning coincided with the highest proportion of CPS contamination. The most commonly contaminated surfaces were chairs (7/15; 46.7%), examination tables (19/47; 40.4%) and computers (12/35; 34.3%); these items were infrequently included on cleaning lists. Surfaces not included in the checklist were 2.3 times more likely to be contaminated by CPS than those that were included (OR: 2.3, CI 95%: 1.02 -5.35, p-value=.04). MRSA and MRSP were rarely isolated from the environment in the newly opened hospital, indicating it may take time for resistant strains to enter the environment and persist on surfaces. This study identified the possible utility of cleaning checklists for directing cleaning practices and reducing the environmental contamination.

RESUMEN

BACKGROUND: Antimicrobials are commonly used to treat urinary tract disease in dogs. Understanding antimicrobial use is a critical component of antimicrobial stewardship efforts. HYPOTHESIS/OBJECTIVES: To evaluate antimicrobial prescriptions for dogs diagnosed with acute cystitis, recurrent cystitis, and pyelonephritis. ANIMALS: Dogs prescribed antimicrobials for urinary tract disease at veterinary practices in the United States and Canada. MATERIALS AND METHODS: A retrospective review of antimicrobial prescriptions was performed. RESULTS: The main clinical concerns were sporadic bacterial cystitis (n = 6582), recurrent cystitis (n = 428), and pyelonephritis (n = 326). Amoxicillin/clavulanic acid (2702, 41%), cefpodoxime (1024, 16%), and amoxicillin (874, 13%) were most commonly prescribed for sporadic bacterial cystitis. The median prescribed duration was 12 days (range, 3-60 days; interquartile range [IQR], 4 days). Shorter durations were used in 2018 (median, 10 days; IQR, 4 days) compared to both 2016 and 2017 (both median, 14 days; IQR, 4 days; P ≤ .0002). Amoxicillin/clavulanic acid (146, 33%), marbofloxacin (95, 21%), and cefpodoxime (65, 14%) were most commonly used for recurrent cystitis; median duration of 14 days (range, 3-77 days; IQR, 10.5 days). Amoxicillin/clavulanic acid (86, 26%), marbofloxacin (56, 17%), and enrofloxacin (36, 11%) were most commonly prescribed for pyelonephritis; however, 93 (29%) dogs received drug combinations. The median duration of treatment was 14 days (range, 3-77 days; IQR, 11 days). CONCLUSIONS AND CLINICAL IMPORTANCE: Decreases in duration and increased use of recommended first-line antimicrobials were encouraging. Common drug choices and durations should still be targets for antimicrobial stewardship programs that aim to optimize antimicrobial use, concurrently maximizing patient benefits while minimizing antimicrobial use and use of higher tier antimicrobials.

RESUMEN

BACKGROUND: Leptospirosis is a zoonotic disease of concern and an investigation of recent spatio-temporal trends of leptospirosis in dogs in the United States is needed. Leptospira PCR testing has become increasingly used in veterinary clinical medicine and these data might provide information on recent trends of disease occurrence. OBJECTIVES: To identify and describe clusters of PCR-positive Leptospira test results in dogs in the United States. ANIMALS: Leptospira real-time PCR test results from dogs (n = 40 118) in the United States from IDEXX Laboratories, Inc., between 2009 and 2016 were included in the analysis. METHODS: In this retrospective study, spatio-temporal clusters for a real-time PCR-positive test were identified using the space-time permutation scan statistic and the centroid of the zip code reported for each test. A maximum spatial window of 20% of the population at risk, and a maximum temporal window of 6 months were used. RESULTS: Seven statistically significant space-time clusters of Leptospira real-time PCR-positive test results were identified across the United States: 1 each located within the states of Arizona (2016), California (2014-2015), Florida (2010), South Carolina (2015), and 1 each located within the south-central region (2015), midwest region (2014), and northeast region (2011). Clusters ranged from 3 to 108 dogs and were identified during all years under study, except 2009, 2012, and 2013. CONCLUSIONS AND CLINICAL IMPORTANCE: The spatial and temporal components of leptospirosis in dogs in this study are similar to those in previous work. However, clusters were identified in new areas, demonstrating the complex epidemiology of this disease.

RESUMEN

Widespread use of antimicrobials in human and veterinary medicine drives the emergence and dissemination of resistant bacteria in human, animal, and environmental reservoirs. The AVMA and FDA Center for Veterinary Medicine have both taken public positions emphasizing the importance of incorporating antimicrobial stewardship in veterinary clinical settings; however, a model for implementing a comprehensive antimicrobial stewardship program in veterinary practice is not readily available. In 2015, The Ohio State University College of Veterinary Medicine began developing a veterinary antimicrobial stewardship program modeled on existing programs in human health-care institutions and the 7 core elements of a successful hospital antimicrobial stewardship program, as defined by the CDC. The program includes comprehensive antimicrobial use guidelines, active environmental surveillance, and enhanced infection control procedures in The Ohio State University Veterinary Medical Center, along with routine monitoring and reporting of antimicrobial prescribing practices and antimicrobial susceptibility patterns of common pathogens isolated from patients and the hospital environment. Finally, programs have been developed to educate clinicians, staff, and students on antimicrobial resistance and appropriate antimicrobial prescribing practices. The antimicrobial stewardship program has been designed to help clinicians and students confidently make judicious antimicrobial use decisions and provide them with actionable steps that can help them act as strong stewards while providing the best care for their patients. This report describes our program and the process involved in developing it, with the intent that the program could serve as a potential model for other veterinary medical institutions.

RESUMEN

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.

RESUMEN

OBJECTIVE: To describe characteristics of intrahousehold interdog aggression (IDA) and dog and pair factors associated with a poor outcome (permanent separation, rehoming, or euthanasia of dogs). ANIMALS: 305 pairs of dogs (610 dogs) with IDA. PROCEDURES: The record database of a referral veterinary behavioral clinic was searched to identify pairs of dogs that were evaluated for IDA (IDA pairs) between September 2007 and September 2016. A standardized form was used to extract data for each IDA pair, including signalment and acquisition order of both dogs, history of IDA, behavioral interventions implemented, and outcome. Descriptive data were generated. Univariable logistic regression was used to identify factors associated with a poor outcome. RESULTS: Most IDA pairs included at least 1 female dog (214/305 [70%]) and dogs of the same sex (188/305 [61.6%]). Resource guarding was the most common fight trigger (222/305 [72.8%]). Possessive aggression (guarding of physical resources) was the most common comorbidity for individual dogs (216/610 [35.4%]). The aggressor was acquired after the recipient in 181 of 305 (59.3%) pairs. Aggressors were a mean of 16 months younger and 1.5 kg (3.3 lb) heavier than recipients. Factors associated with a poor outcome included pairs of the same sex, history of bites that broke the skin, and aggression on sight of the recipient. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that behavior intervention should be provided quickly for IDA pairs with a history of bites that break the skin or uninhibited attacks on sight owing to the high risk for a poor outcome.

RESUMEN

INTRODUCTION: Ingestion of buprenorphine by young children is on the rise and can lead to life-threatening consequences and death. Exposure most often occurs when a child acquires the medication intended for adult use. However, buprenorphine is also prescribed by veterinarians and may be sent home, typically in non-child-resistant packaging, to be administered to the family pet. CASE: A previously healthy 2-year-old girl weighing 11.36 kg was found with a 1-mL syringe containing 0.6 mg/mL of buprenorphine in her mouth. The syringe had been in a plastic bag provided to the family by their veterinarian for the family dog. She was hospitalized for 24 hours but remained asymptomatic and was discharged healthy. This type of exposure to buprenorphine has not previously been described in the literature. CONCLUSIONS: Having this unsecured medication in the home increases the potential risk of exposure for young children and associated health consequences. Pediatricians should be aware of the potential dangers that veterinary pharmaceuticals can pose and educate parents about proper storage of medications. In addition, veterinarians should take extra precautions when dispensing these medications to pet owners with children.

RESUMEN

BACKGROUND: Canine leptospirosis is a reemerging zoonotic disease concern in North America, and a better understanding of its epidemiology is needed. Wide-scale use and subsequent analyses of polymerase chain reaction (PCR) testing may provide additional insight into leptospirosis. This study aimed to describe temporal trends, to descriptively map, and to identify environmental, dog, and human-level factors associated with positive canine leptospirosis PCR test results in the United States. RESULTS: Data obtained from IDEXX Laboratories, Inc. on 40,118 canine leptospirosis PCR tests run in the United States between 2009 and 2016 were evaluated. Climate and socioeconomic (e.g. urban influence, income) data were obtained from public databases. Choropleth maps were created to identify high test-positive proportion areas and a cross-sectional analysis was completed with generalized (univariable, followed by multivariable) mixed logistic regression models accounting for county within state to identify significant predictors for a positive test. Overall test-positive proportion was 5.4% across the United States, with the regional point estimate highest in the southwest (8.1%). In the final multivariable model, the odds of a positive test were greater for male dogs (Odds Ratio [OR] = 1.28) and dogs 0-4 years of age (ORs ranged from 0.35-0.71 for the other age groups). The odds of a positive test were greater for dogs living in areas with wet environmental conditions (OR = 1.24). Season and temperature, as well as the interaction between them, were significant predictors of a positive test. Dogs had a greater probability of testing positive during cool temperatures (< 4 °C) compared to the other temperature categories in the fall season. CONCLUSIONS: These findings based on PCR testing allow for an improved understanding of factors influencing a positive canine leptospirosis PCR test and will assist targeted education and prevention efforts.

RESUMEN

Swine are known reservoirs for Clostridioides difficile, formerly known as Clostridium difficile, and transmission from swine to human farm workers is strongly suggested by previous studies. This cross-sectional study evaluated the potential role of farm environmental surfaces, including those in worker breakrooms and swine housing areas, in the possible transmission of C. difficile from swine to farm workers. Environmental surfaces and piglet faeces at 13 Ohio swine farms were sampled in 2015. Typical culturing techniques were performed to isolate C. difficile from samples, and amplification of toxin genes (tcdA, tcdB and cdtB) and PCR-ribotyping were used to genetically characterize recovered isolates. In addition, sequencing of toxin regulatory gene, tcdC, was done to identify the length of identified deletions in some isolates. A survey collected farm-level management risk factor information. Clostridioides difficile was recovered from all farms, with 42% (188/445) of samples testing positive for C. difficile. Samples collected from all on-farm locations recovered C. difficile, including farrowing rooms (60%, 107/178), breakrooms (50%, 69/138) and nursery rooms (9%, 12/129). Three ribotypes recovered from both swine and human environments (078, 412 and 005) have been previously implicated in human disease. Samples taken from farrowing rooms and breakrooms were found to have greater odds of C. difficile recovery than those taken from nursery rooms (OR = 40.5, OR = 35.6, p < .001 respectively). Farms that weaned ≥23,500 pigs per year had lower odds of C. difficile recovery as compared to farms that weaned fewer pigs (OR = 0.4, p = .01) and weekly or more frequent cleaning of breakroom counters was associated with higher odds of C. difficile recovery (OR = 11.7, p < .001). This study provides important insights into the presence and characterization of C. difficile found in human environments on swine farms and highlights how these areas may be involved in transmission of C. difficile to swine farm workers and throughout the facility.

RESUMEN

BACKGROUND: The influenza A virus (IAV) binds to α-2,3- and α-2,6-linked sialic acid (SA) receptors expressed by Madin-Darby canine kidney (MDCK) cells. The receptor distribution may therefore be important in regulating IAV propagation. Serum-free medium (SFM) avoids variability in conventional culture medium containing fetal bovine serum (FBS), which can have variable composition and may contain endotoxins. However, little is known about the distribution of SA receptors on cells maintained in SFM. OBJECTIVES: We assessed the influence of culture media on MDCK cell SA receptor distribution along with the effect of SA receptor distribution on IAV recovery. We hypothesized that SFM would increase the proportion of α-2,6-linked SA receptors present and alter isolate recovery. METHODS: Madin-Darby canine kidney cells were cultured in medium containing FBS and two SFMs. Cell surface distribution of α-2,6- and α-2,3-linked receptors was determined using flow cytometry. Recovery of swine- and avian-lineage IAVs from MDCK cells maintained in each medium was quantified as TCID50 . RESULTS: Madin-Darby canine kidney cells cultured in UltraMDCK SFM expressed both SA receptors and supported the growth of both swine- and avian-lineage IAVs. Cells maintained in other medium inconsistently expressed each receptor and the avian IAV grew to lower titers in cells cultured with FBS. CONCLUSIONS: Medium conditions altered the distribution of SA receptors present on MDCK cells and affected IAV recovery. Culture in UltraMDCK SFM resulted in cells expressing both receptors and IAVs grew to higher titers than in the other culture condition, indicating that this medium may be useful for culturing IAV from multiple species.

RESUMEN

Canine and feline infectious diseases are constantly changing in frequency and location. Numerous drivers or determinants of these changes are suspected, including emergence of new pathogens; change in virulence and resistance of existing pathogens; change in land use, climate, and weather; travel and trade; habitat destruction and urbanization; change in animal-animal contact networks; host susceptibility; availability and uptake of prevention measures; and change in ability to detect pathogens and track diseases. This article explores each of these proposed drivers and examines examples of feline and canine diseases likely to be influenced by them.
