Resumo
Background: This study aimed to assess the level of bacterial contamination in the Small Animals Sector of the VeterinaryMedical Teaching Hospital (HCV) of the Universidade Federal do Rio Grande do Sul (UFRGS). Firstly, a committee wasinvited to complete a questionnaire and to list critical sample sites for collection. With the identification of the places to besampled, collections were made with sterile swabs on different surfaces of environments of the HCV. The identification ofimportant bacteria in the veterinary area, in the different sampled environments, raises the concern for hygiene proceduresin the veterinary hospital environment.Materials, Methods & Results: Sixteen samples were collected from these different areas, and microbiological analyses wereperformed. Standard counts of viable and strictly aerobic mesophilic microorganisms were realized. Collections were madeto assess ambient air quality. With the microbiological analysis performed, bacteria of clinical importance were identified.To assess the resistance profile of the bacteria, the susceptibility test to antimicrobials was performed. MALDI-TOF/MSmeasurement identified 29 bacteria at the genus level and 10 bacteria at the species level and the antimicrobial susceptibility test was realized. Most of the isolates identified (60%) were bacteria of the genus Staphylococcus spp. Regardingantimicrobial susceptibility analysis the 10 bacteria identified at the species level were assessed. Test results showed thatthe isolates S. aureus, S. epidermidis and S. haemolyticus - collected from treatment room 2 - and S. haemolyticus, whichhad been isolated from samples from treatment room 2 of the cattery, presented multiresistance. Pantoea ananatis isolatesfrom room 5 also showed a multiresistant profile for erythromycin, cephalothin, vancomycin and ampicillin. Micrococcusluteus isolates from the x-ray room and the kennel showed resistance to ceftazidime. Staphylococcus equorum isolates...(AU)
