Use of GBS media for rapid detection of group B streptococci in vaginal and rectal swabs from women in labor.

In order to evaluate the differences in efficacy, three methods were used to detect group B streptococci (GBS) in women in labor. The recommended method for detecting GBS carriage in pregnant women is to culture vaginal and anorectal swabs in a selective broth medium and to subculture them onto blood agar. This method was compared with the use of GBS agar and GBS broth, both of which produce an orange pigment in response to GBS strains.

Review of the incidence and prognosis of Pseudomonas aeruginosa infections in cancer patients in the 1990s.

In an attempt to determine the actual relevance of Pseudomonas aeruginosa as a target of empiric antimicrobial first-line therapy in febrile cancer patients, 44 reports of clinical trials on antimicrobial treatment regimens and 53 reports on the epidemiology of microbiologically documented infections in cancer patients were reviewed. The incidence of infections due to Pseudomonas aeruginosa was 1-2.5% among all patients presenting with first fever during neutropenia, and 5-12% among patients with microbiologically documented infections.
