Incidence of bacteria from clean-catch and catheterized urine of nursing home residents.
Urine cultures from 1990 through 1992 were analyzed to determine the incidence of common isolates in residents from over 50 nursing homes in Oklahoma. Of all 11,480 isolates in clean-catch and catheterized specimens, the most common were: Escherichia coli (24% of all isolates), Pseudomonas aeruquinosa (11%), Proteus mirabilis (10%), Enterococcus faecalis (8%), Klebsiella pneumoniae (7%), Providencia stuartii (5%), and Staphylococcus aureus (4%). The most striking findings of this study were the similarities in frequencies of isolates from clean-catch and catheterized urines, the common occurrence of P. stuartii, and the low proportion of urea-splitting P. stuartii isolates from catheterized specimens.
