“…Results from the simulations done with randomized parameter values and subsequent regression analyses suggest that the model is consistent with previous reports that the incidence of both resistant and non-resistant strain colonization increases with increasing length of stay in the hospital [14], [15], [33]. As long as the number of patients already hospitalized is below the maximum capacity for the hospital, longer patient stays contribute to a higher number of hospitalized patients, leading to more interactions between patients, healthcare workers and transmission points.…”

“…Risk-based case control studies have shown that hospitalization is a serious risk factor for dogs becoming rectal carriers of multi-drug resistant (MDR) E. coli [14], [15]. Dogs staying for over 6 days experience an increased risk of carrying MDR E. coli while those patients who had been hospitalized previously and/or had been treated with fluoroquinolones previously had higher probability of carrying MDR E. coli on arrival to the hospital.…”

An Individual-Based Model of Transmission of Resistant Bacteria in a Veterinary Teaching Hospital

Veterinary nosocomial infections caused by antibiotic resistant bacteria cause increased morbidity, higher cost and length of treatment and increased zoonotic risk because of the difficulty in treating them. In this study, an individual-based model was developed to investigate the effects of movements of canine patients among ten areas (transmission points) within a veterinary teaching hospital, and the effects of these movements on transmission of antibiotic susceptible and resistant pathogens. The model simulates contamination of transmission points, healthcare workers, and patients as well as the effects of decontamination of transmission points, disinfection of healthcare workers, and antibiotic treatments of canine patients. The model was parameterized using data obtained from hospital records, information obtained by interviews with hospital staff, and the published literature. The model suggested that transmission resulting from contact with healthcare workers was common, and that certain transmission points (housing wards, diagnostics room, and the intensive care unit) presented higher risk for transmission than others (lobby and surgery). Sensitivity analyses using a range of parameter values demonstrated that the risk of acquisition of colonization by resistant pathogens decreased with shorter patient hospital stays (P<0.0001), more frequent decontamination of transmission points and disinfection of healthcare workers (P<0.0001) and better compliance of healthcare workers with hygiene practices (P<0.0001). More frequent decontamination of heavily trafficked transmission points was especially effective at reducing transmission of the model pathogen.

“…A recent study conducted in Netherlands reported a high prevalence of faecal carriage of Enterobacteriaceae resistant to third-generation cephalosporins in cats and dogs (Hordijk et al, 2013). Various risk-based case control studies reported that hospitalization is a major risk associated with the dogs to become multi-drug resistant (MDR) E. coli rectal carriers (Gibson et al, 2011;Hamilton et al, 2013). Enterobacter cloacae, also a nosocomial agent and particularly the multidrug resistant strains, are concerning (Wilberger et al, 2012).…”

“…Veterinary hospitals are the major source and accountable for increasing prevalence of a MDR E. coli in horses (Ahmed et al, 2012). Veterinary personnel and veterinary hospital environments are allegedly most important key factors in risk of gaining antibiotic resistant pathogens by hospitalized dogs (Hamilton et al, 2013;Heller et al, 2010;KuKanich et al, 2012). …”

| Nosocomial, or hospital-acquired, infections are well-thought-out to be the most common problem affecting hospitalized human patients as well as veterinary patients. These are of great consequence in veterinary medicine and can have considerable adverse effects on the individual patient as well as on the veterinary hospital as a whole. Different infectious agents like MRSA, Cl. difficile, MDR E. coli, Salmonella spp. and many more are of prodigious significance in causing NIs. A surveillance and control measure for these NIs in veterinary settings needs to be addressed in future. This review consolidates some Nosocomial infections and the strategy for its surveillance in veterinary practice.

“…Pour autant, les infections nosocomiales enzootiques ne devraient pas être sous-estimées et la réalité des infections nosocomiales en médecine vétérinaire est probablement sous-estimée (Morley, 2013). Par ailleurs, plusieurs études ont démontré une association significative entre l'hospitalisation et le portage de bactéries multi-résistantes chez l'animal (Gibson et al 2011;Nienhoff et al 2011;Hamilton et al 2013).…”

Probablement sous-estimées en médecine vétérinaire, les infections nosocomiales ont des consé-quences sanitaires mais aussi économiques ; en outre elles peuvent ternir la réputation des établisse-ments. Elles sont associées à des facteurs de risque variés, intéressant plusieurs aspects de la médecine vétérinaire. Elles peuvent être d'origine endogène ou exogène, et dues à des agents pathogènes ou opportunistes divers. La maîtrise des infections nosocomiales vise à interrompre la chaîne de transmission et à réduire la vulnérabilité de l'hôte. Elle repose sur une approche globale, intégrant l'ensemble de l'organisation de l'établissement vétérinaire. La maîtrise des risques d'infection d'origine exogène repose essentiellement sur l'isolement des animaux infectés ou colonisés, la gestion des flux, les pratiques d'asepsie adaptées et les mesures d'hygiène. Elle concerne également l'utilisation d'équipe-ments adaptés afin de limiter les infections liées aux contaminants de l'environnement. Le contrôle de la qualité de l'environnement permet la surveillance de points critiques et la recherche des sources de contamination. Des procédures doivent décrire les règles de biosécurité dans l'établissement. Mots-clés
