ISOLATED RESISTANT BACTERIA FROM INANIMATE SURFACES IN A PUBLIC HOSPITAL

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.

BACTERIAS RESISTENTES AISLADAS DE SUPERFICIES INANIMADAS EN UN HOSPITAL PÚBLICO RESUMEN: Objetivo: describir el perfil de resistencia de microrganismos presentes en superficies inanimadas a agentes antimicrobianos. Método: estudio descriptivo realizado entre febrero y junio de 2018. Se recolectaron 40 muestras microbiológicas de superficies de la Clínica Médica y de la Unidad de Cuidados Intensivos para Adultos de un hospital de Mato Grosso, Brasil. Los procesos de identificación y sensibilidad microbiana se realizaron a través del dispositivo VITEK 2. El análisis de los resultados de resistencia se evaluó conforme a las directrices del Clinical Laboratory Standards Institute. Resultados: se aislaron 32 microrganismos de las 22 muestras contaminadas; entre ellos, hubo 14 (43,8%) Staphylococcus coagulasa negativa, siete (21,9%) Acinetobacter baumanni complex y tres (9,4%) Enterobacter aerogenes. Entre los Staphylococcus coagulasa negativa, 11 (78,6%) presentaron multi-resistencia a agentes antimicrobianos y tres (42,9%) de los aislados bacterianos de Acinetobacter baumanni complex fueron extremamente resistentes. Conclusión: se hizo evidente la necesidad de instrucción con énfasis en la correcta y frecuente desinfección de superficies y en el lavado de manos después de entrar en contacto con el paciente y con las superficies próximas al paciente.
