Isolated resistant bacteria from inanimate surfaces in a public hospital

Abstract

Objective: to describe the antimicrobial resistance profile of microorganisms present on inanimate surfaces. Method: a descriptive study, conducted between February and June 2018. Forty microbiological samples were collected from surfaces of the Medical Clinic and Intensive Care Unit for Adults in a hospital located in Mato Grosso, Brazil. Microbial identification and sensitivity were performed by means of VITEK 2. The analysis of the resistance results was assessed according to the Clinical Laboratory Standards Institute guidelines. Results: a total of 32 microorganisms were isolated from the 22 contaminated samples, the following among them: 14 (43.8%) Coagulase-Negative Staphylococcus, seven (21.9%) Acinetobacter baumanni complex, and three (9.4%) Enterobacter aerogenes. Of the Coagulase-Negative Staphylococcus, 11 (78.6%) presented multi-drug resistance to antimicrobial agents, and three (42.9%) of the Acinetobacter baumanni complex isolates were extremely resistant. Conclusion: this study evidenced the need for education with emphasis on proper and frequent disinfection of surfaces and on hand hygiene after touching patients and surfaces close to them.
