ABSTRACT

Background:

The presence of resistant and potentially virulent bacterial strains in a veterinary hospital environment is a neglected problem. Pseudomonas aeruginosa is an opportunistic microorganism present and circulating in the veterinary hospital environment, of clinical importance and zooanthroponotic transmission of P. aeruginosa has also been reported. The aim of this study was to characterize the population of P. aeruginosa present in a veterinary hospital environment by evaluating their resistance profile and biofilm production. Materials, Methods &

Results:

A total of 306 samples were collected from the veterinary hospital environment (swabs from consultation tables, surgical tables, door handles, hospitalization cages, stethoscopes, thermometers, and muzzles). The isolates were biochemically identified as belonging to the species Pseudomonas aeruginosa through nitrate to nitrite reduction, motility and oxidase test, growth at 42°C, pigment production, and alkalinization of acetamide. Antimicrobial resistance was tested using the minimum inhibitory concentration (MIC) test. Twenty seven isolates of P. aeruginosa were obtained, with a frequency of 8.8%. The detection of beta-lactamase production and biofilm formation genes by polymerase chain reaction (PCR). Two multidrug resistant (MDR) and 3 single-drug resistant (SDR) strains of P. aeruginosa were identified. Furthermore, it was observed that the strains carried genes related to beta-lactamase production (TEM and CTX-M group 25) and biofilm production (pelA, pslA, ppyR).

Discussion:

Pseudomonas aeruginosa is considered a major cause of opportunistic hospital infections, as it causes significant morbidity and mortality in immunosuppressed individuals, both in...
