ISOLAMENTO E IDENTIFICAÇÃO DE MICRORGANISMOS PRESENTES EM SUPERFÍCIES DE TECLADOS E MOUSES DE UMA UNIVERSIDADE DE TRÊS LAGOAS, MS

Abstract

Objects can be important vehicles for the transmission of microorganisms. We aimed to study the occurrence of microorganisms from keyboards and mouse computers of a Education Institution. Swab was rubbed on the surfaces of keyboards and mouse computers and used for isolation in specific culture media of bacteria and fungi. Observed a large number of bacterial isolates, mainly of the genera: Staphylococcus spp, Streptococcus spp, Enterococcus spp, Corynebacterium spp, Escherichia ssp, and others Gram negative bacillus. Interestingly, strains of Gardnerella spp and Legionella spp were isolated from one samples. Among the fungi, we observed 30 different species, mainly of the genera: Absidia sp, Acremonium sp, Aspergillus sp, Candida sp, Fusarium sp, sp Geotrichum, Malassezia spp, Microsporum sp, Pinicillum sp, Rhodotorula sp, Trichoderma sp, Trichophyton sp and Tricosporum sp. Therefore, we conclude that these objects can be important vehicles of transmission of microorganisms for humans.
