ABSTRACT
The objective of this study was to evaluate the morphological changes in methicillin-resistant staphylococcus aureus (MRSA) cultured in different concentrations of sodium chloride and oxacillin. In a previous study on the prevalence of MRSA and methicillin-susceptible staphylococcus aureus (MRSA) un the saliva of health workers, 12 samples of MRSA were isolated and identified using conventional techniques and polymerase chain reaction (PCR). Morphological and morphometric analyses showed that the culture of methicillin-resistant S. aureus in different concentrations of sodium chloride (2 percent, 4 percent, 6 percent and 7.5 percent) and oxacillin (2µg, 4 µg and 6µg/mL) had effect on the morphology of the bacteria.
RESUMO
Este estudo teve como objetivo avaliar alterações morfológicas em staphylococcus aureus resistente à meticilina (MRSA) após o cultivo em meios contendo diferentes concentrações de cloreto de sódio e oxacilina. Em um estudo prévio sobre a prevalência de MRSA e de staphylococcus aureus susceptível à meticilina (MSSA) na saliva de profissionais de saúde, 12 amostras de MRSA foram isoladas e identificadas por técnicas convencionais e pela reação em cadeia da polimerase (PCR). Análises morfológicas e morfométricas mostraram que a cultura de S. aureus em diferentes concentrações de cloreto de sódio (2 por cento, 4 por cento, 6, por cento, 7.5 por cento) e oxacilina (2µg, 4 µg e 6µg/mL) não promoveu qualquer efeito sobre a morfologia das bactérias.
