title: Identification of gram positive cocci isolated from urine.
abstract: A total of 195 strains of Gram positive cocci isolated from urine, in pure culture and in counts of > 10(3) colony forming units/ml, during January-September 1992, were speciated using schema recently described by Facklam and Washington, and Kloos and Lambe. Seventy three (85%) of the 86 enterococci were identified as Enterococcus faecalis while 11 (13%) were E. faecium. Eighteen (29%) of the 62 staphylococcal isolates were Staphylococcus aureus; 20 (45%) of the 44 coagulase negative staphylococci were speciated as Staph. haemolyticus. Of the 47 strains of beta haemolytic streptococci isolated, 45 (96%) were group B; one was group G and the other group F. Our results show the diverse species of Gram positive cocci associated with bacteriuria and the need to speciate them in a diagnostic laboratory. In the context of a larger number of tests required for the speciation of Gram positive cocci, we recommend a simplified scheme which we found feasible on a routine basis.
