ANÁLISE MORFOMÉTRICA DE STAPHYLOCOCCUS AUREUS RESISTENTE À METICILINA ISOLADO DA SALIVA DE PROFISSIONAIS DE SAÚDE

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 (MSSA) in 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%, 4%, 6% and 7.5%) and oxacillin (2 µg, 4 µg and 6 µg/ml) had no effect on the morphology of the bacteria
