要旨
A new medium containing 5-bromo-4-chloro-3-indolyl-beta-D-glucuronide cyclohexylammonium salt (Glu agar) for Escherichia coli and a new medium containing 5-bromo-3-indolyl-beta-D-galactoside (Gal agar) for beta-galactosidase-positive members of the family Enterobacteriaceae were compared with MacConkey agar in a diagnostic trial with 3,562 urine specimens. The isolation rates of E. coli and beta-galactosidase-positive Enterobacteriaceae were increased 8.4 and 19.5%, respectively. The sensitivities and specificities of Glu agar and Gal agar were 98.5 and 100% and 99.2 and 99.5%, respectively.
