Abstract
The efficiency of three commercially available blood culture systems for isolatingCampylobacter sp. was investigated. Thirteen of 189,688 blood cultures from patients seen at the Mayo Clinic from 1984 through 1990 were positive forCampylobacter sp. Eleven out of 13 blood cultures positive forCampylobacter sp. were part of a complete three bottle set of cultures (Isolator from Du Pont, Roche Septi-Chek from Hoffman-La Roche, and non-vented Tryptic Soy Broth from Difco), none of them providing a specific microaerophilic mileu. The aerobic Roche Septi-Chek seems to be more efficient for the detection ofCampylobacter sp. in blood cultures than either the anaerobic Tryptic Soy Broth (Difco) or the Isolator (Du Pont) using the incubator condition of 5% CO2. Drei kommerzielle Blutkultursysteme wurden auf ihre Eignung für den Nachweis vonCampylobacter sp. untersucht. In den Jahren 1984 bis 1990 waren 13 von 189.688 Blutkulturen von Patienten der Mayo Clinic positiv fürCampylobacter sp. Elf dieser 13 Blutkulturen bestanden aus einem Set von drei gleichzeitig beimpften Systemen (Isolator von Du Pont, Roche Septi-Chek von Hoffman-La Roche und unbelüftete Tryptic Soy Broth von Difco); keines dieser Systeme bietet dezidiert ein mikroaerophiles Milieu. Das aerobe System von Hoffman-La Roche (Roche Septi-Chek) erwies sich im Hinblick auf den Nachweis vonCampylobacter-Bakteriämien sowohl der anaeroben Tryptic Soy Broth von Difco als auch dem Isolatorsystem von Du Pont mit Bebrütung der Platten in 5% CO2 als überlegen.Keywords
