RESUMO
A total of 165 strains of coagulase positive staphylococci (CPS) and 39 strains of coagulase negative Staphylococci (CNS) isolated from various clinical specimens studied for biochemical and enzyme profile showed overlapping of the key characters of pathogenicity. Anaerobic mannitol fermentation (69.20%), phosphatase (58.97%) and penicillinase (58.97%) production was remarkable amongst CNS. Both CPS and CNS showed increased resistance to penicillin and other antimicrobials. Besides increased frequency of isolation of CNS from pathological specimens, they elaborate singly or in combination, the recognized virulence factors.

Two hundred patients in the first trimester of pregnancy presenting with complications were evaluated both clinically and by ultrasonography. The ultrasonographic interpretations were classified as either confirmatory, diagnostic or misleading based on their correlation with the clinical diagnosis. It was observed that in 51% cases sonography was confirmatory, in 41% diagnostic and in 8% misleading. Used judiciously, ultrasonography provides a reliable aid in management of early pregnancy complications.
