Objective – Investigate the prevalence of the bacteria Pseudomonas aeruginosa in water samples and surface collected earlier in a private company, located in the northwest of the state of São Paulo and determine the susceptibility of this microorganism to different antimicrobials. Methods – Water samples and swabs were collected from surface in a hatchery located in the northwestern state of São Paulo. For isolation, seeding techniques were performed to identify the pigment pyocyanim by ultraviolet light. Regarding the resistance profile, the strains were submitted to antibiotic susceptibility test with antibiotics enrofloxacin, ciprofloxacin, norfloxacin, colistin, sulfametazol and trimethoprim, fosfomycin, gentamicin, neomycin, streptomycin, tetracycline, doxycycline, amoxicillin, ceftiofur. Results –A total of 402 samples were analyzed, and 21 of them were positive for P. aeruginosa. The samples showed resistance or intermediate resistance to at least one class of antimicrobial tested. Conclusions – The results obtained in this study show the ability of Pseudomonas aeruginosa has to survive in humid, with minimum conditions of nutrients, even when subjected to constant cleaning, in addition to broad resistance profile seen across the various drugs used in the treatment of infections caused by this pathogen.
