Antimicrobial Resistance and Biofilm Formation in Bacterial Species Isolated from a Veterinary Hospital

Microorganisms are abundantly dispersed in nature and can also be found in hospital environments, causing high rates of infections. This study aims to identify bacteria isolated from a veterinary hospital as well as carry out antimicrobial susceptibility testing, biofilm production tests, and genetic analysis of the ica operon of the isolates. Three collections were carried out on 11 surfaces and objects from general areas and the hospital’s operating room, totaling 33 samples, with 66 different bacterial species isolated, 77% (51/66) of them gram-positive and 23% (29/66) gram-negative. MDR, MRSA, MRS and ESBL resistance profiles were found, as well as biofilm production rates of 57% (38/66) of the isolates. Analysis of operon genes for Staphylococcus sp. demonstrated divergence in some samples when compared to the phenotypic test performed. In summary, there is a high presence of microorganisms with resistance and virulence factors spread throughout the various facilities of the veterinary hospital.
