Abstract

The purpose of this investigation was to study the changes of isolated strains between monomicrobial and polymicrobial isolation from urinary tract in patients of Tsukuba University Hospital from 1980 to 1982.
1) In the monomicrobial isolation of the inpatient, E.coli was the most common isolate (583 strains, 18.3%).S.marcescens was the second (463 strains, 14.5%) and P. aeruginosa the third (403 strains, 12.6%).
2) In the polymicrobial isolation, Enterococcus group was the most common isolate (975 strains, 47.1%).P.aeruginosa was the second (458 strains, 28.7%) and E.coli the third (405 strains, 25.4%). Enterococcus group had a tendency to increase through three years.
3) E.coli was isolated more frequently in 20 to 40 years old age group and P.aeruginosa was isolated less in 10 to 40 years age group.
4) E.coli was isolated more frequently from the female than the male while S.marcescens was isolated more frequently from the male than the female in both monomicrobial and polymicrobial isolation.
5) The most frequent combination of bacteria in polymicrobial isolation was that of Enterococcus group and P.mirabilis.
