Análise microbiológica de superfícies em banheiros, computadores e livros didáticos em uma universidade em Realeza - Paraná

Abstract

All environments of our everyday are fit to be contaminated by microorganisms. Surfaces as computer keyboards of collective use, taps for public restrooms and library are constantly exposed to contamination. The objective of the study was to evaluate microbial contamination in the different spaces used by the academic community, verifying the presence of potentially pathogenic bacterial microorganism. The collect was done using swabs soaked in Nutrient Broth, rubbed surfaces, and transported to the microbiology laboratory. Were analyzed the presence of coliforms, Staphylococcus spp and aerobic mesophiles. The analysis showed that of the three areas analyzed, the restrooms taps presented higher mean contamination by coliforms, succeed from computer keyboards, and the books surfaces. As to aerobic mesophiles microorganism, the higher mean contaminations were in the books surfaces, succeed from restooms taps and computer keyboards. It was not evidenced growth of microorganism of the genus Staphylococcus spp, leading to the conclusion that microorganisms were not present in the sample. It was observed that the microbiological quality of surfaces presented unsatisfactory hygiene conditions. With the results it is expected that the surfaces receive more attention on the question of asepsis, and that the users are sensitize as hand hygiene.
