Abstract(s)
As micobactérias não tuberculosas (MNTs) são agentes infeciosos emergentes
responsáveis por infeções diversas, nomeadamente infeções associadas
aos cuidados de saúde. Neste trabalho foi avaliada a capacidade
de formação de biofilmes por duas MNTs (M. smegmatis e M. chelonae).
Os biofilmes foram caracterizados utilizando microscopia eletrónica e a
eficácia de diversos desinfetantes foi avaliada contra MNTs recuperadas
de biofilmes. Os resultados obtidos demonstram que as MNTs são capazes
de formar biofilmes em materiais presentes em ambiente hospitalar e
de resistir à ação de diversos desinfetantes.
Non-tuberculous mycobacteria (NTMs) are emerging infectious agents responsible for various infections, namely, health-care-associated infections. In this work, biofilms assembly by two NTMs (M. smegmatis and M. chelonae) was assessed. Biofilms were characterized using electron microscopy and the ef ficacy of several disinfectants was determined against NTMs recovered from biofilms. The results obtained demonstrate that NTMs are able to assemble biofilms on materials present in a hospital environment and to resist the action of various disinfectants.
