[Studies on coagulase negative Staphylococci isolated from urine].
This study was conducted to invesitigate the relative frequency of Staphylocossus spp. and coagulase negative Staphylococci (CNS) isolates from urine at Juntendo University Hospital in Tokyo. The frequency of Staphylococci spp. was encountered in about 10% of the cases from 1984 to 1994 (except 1992 and 1993), and no significant annual changes were observed. The frequency of Staphylococcus aureus has been gradually increasing from 1986. The relative frequency of CNS (321 strains) from 1989 to 1994 were as follows; Staphylococcus epidermidis 36%, Staphylococcus saprophyticus 26%, Staphylococcus haemolyticus 22%, Staphylococus caprae 8%, and other CNS 8%. S. saprophyticus, most of which were isolated from female out-patients, were suggested to be the important pathogen of acute urinary tract infections. All of S. caprae were isolated from male patients. Most of S. epidermidis isolated from inpatients of urinary tracts with other bacteria.
