Does colonization with MRSA, ESBL - producing Enterobacteriaceae, and/or Acinetobacter baumannii - increase the risk for postoperative surgical site infection?

Objective: Evaluation of the role of indicator pathogens in equine surgical site infection (SSI) and other infection-promoting factors.

Study Design: Cross-sectional study.

Animals: Horses presenting with an open injury or surgical colic during 1.

Molecular Characterization of Equine Isolates Exhibiting Reduced Oxacillin Susceptibility.

The detection of borderline oxacillin-resistant (BORSA) represents a challenge to both, veterinary and human laboratories. Between 2015 and 2017, 19 equine with elevated minimal inhibitory concentrations for oxacillin were detected in routine diagnostics. The aim of this study was to characterize these isolates to identify factors possibly associated with the BORSA phenotype.

Equine Methicillin-Resistant Sequence Type 398 (MRSA) Harbor Mobile Genetic Elements Promoting Host Adaptation.

Continuing introduction of multi-drug resistant, zoonotic pathogens such as methicillin-resistant (MRSA) in horse clinics challenges the biosafety of employees and animal patients. This study was aimed to determine the occurrence of mobile genetic elements facilitating survival in the early stages of invasive infection in different host species, including humans and horses, in MRSA carried by equine patients admitted to a large horse clinic. A total of 341 equine patients were investigated for carriage of MRSA by hygiene screening directly at hospital admission.

Extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli and Acinetobacter baumannii among horses entering a veterinary teaching hospital: The contemporary "Trojan Horse".

Pathogens frequently associated with multi-drug resistant (MDR) phenotypes, including extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae (ESBL-E) and Acinetobacter baumannii isolated from horses admitted to horse clinics, pose a risk for animal patients and personnel in horse clinics. To estimate current rates of colonization, a total of 341 equine patients were screened for carriage of zoonotic indicator pathogens at hospital admission. Horses showing clinical signs associated with colic (n = 233) or open wounds (n = 108) were selected for microbiological examination of nostril swabs, faecal samples and wound swabs taken from the open wound group.
