Pf. Schneider et Tv. Riley, STAPHYLOCOCCUS-SAPROPHYTICUS URINARY-TRACT INFECTIONS - EPIDEMIOLOGICDATA FROM WESTERN-AUSTRALIA, European journal of epidemiology, 12(1), 1996, pp. 51-54
Epidemiological data from Western Australia regarding Staphylococcus s
aprophyticus urinary tract infections (UTIs) was collected over a 12 m
onth period. Eighty-four percent of S. saprophyticus UTIs occurred in
females 13-40 years of age and S. saprophyticus was the second most fr
equent cause of UTIs in this age group (15.2%) after Escherichia coli
(70.8%). Although the monthly incidence fluctuated, no seasonality of
S. saprophyticus UTIs could be demonstrated. The proportion of S. sapr
ophyticus UTIs in pregnant women (6.5%) compared with non-pregnant wom
en (15.2%) appeared reduced, however, this reduction was not statistic
ally significant. Finally, while S. saprophyticus was isolated at a fr
equency of 4.6% from the genital tract of females aged 13-40 years, it
could not be isolated from the genital tract of females aged > 40 yea
rs, nor from the genital tract of males aged 13-40 years, suggesting a
possible reservoir of infection. These data imply a relationship betw
een female hormonal status and S. saprophyticus UTIs which requires fu
rther investigation.
