Methicillin-resistant Staphylococcus aureus (MRSA) has been one of the most prevalent microorganisms that cause hospitals infections worldwide. Several studies show that this microorganism is often found colonizing health professionals. MRSA can cause skin infections from the severe pneumonia, with high resistance to different antimicrobial agents. This study aimed to evaluate morphometric changes in MRSA isolated from the saliva of health professionals, through the use of different concentrations of oxacillin and sodium chloride. The identification of morphological changes was assessed by growing the isolates in the following concentrations of Sodium Chloride and oxacillin: 2&#956;g, 4&#956;g and 6&#956;g and 2%, 4%, 6% and 7.5% and using the means of computerized morphometry. This technique was tested by microscopic computed by employing the software Image J 1.38 (HIH USA). Statistical analysis was performed using the Sigma Stat, version 2.03, and the differences between the groups were compared using the nonparametric Kruskal-Wallis (p <0.05). The 20 MRSA analyzed showed no alterations. The present study showed that Sodium Chloride and oxacilin at concentrations did not alter the development and morphology of MRSA.
