Abstract
Objective: To analyze the prevalence of Pseudomonas aeruginosa strains in two laboratories in the city of Governador Valadares, Minas Gerais in 2018. Methods: Descriptive study, retrospective, with quantitative approach. Results: They had 148 positive samples for P. aeruginosa. The predominant age group for Laboratory 1 was 81–90 years (28%), and for Laboratory 2 the age group with highest significance was 41–50 years (29%). As for sites, three stand out with the highest prevalence of positivity: blood (2.2%) and (71.5%) in Laboratory 1 and 2, respectively; secretions in Laboratory 1(25.4%) and Laboratory 2(7.1%). For urine, in Laboratory 1 (42.5%) and in Laboratory 2(21.4%). As for the resistance factor, it was found that P. aeruginosa showed resistance to Amicacine antimicrobials, only in Laboratory 1(17.4%); Cefeprime, Laboratory 1(34.1%) and Laboratory 2(14.2%); Ciprofloxacino, Laboratory 1(38.1%) and Laboratory 2 (21.4%); Gentamicine, Laboratory 1(35.6%) and Laboratory 2(21.4%); Meropenem, only Laboratory 1(27.7%) and, Piperacillin / Tazobactam, only Laboratories 1(12.5%). Conclusion: Further comparative studies are suggested using laboratory samples with longer period to verify the prevalence of these samples and the evolutionary flow of resistance rates.
