title: Effects of atmosphere of incubation on recovery of bacteria and yeasts from blood cultures in Tryptic soy broth.
abstract: A comparison was made of the results of blood cultures between 1974 and 1981 in unvented and transiently vented bottles of Tryptic soy broth under vacuum with CO2. A total of 14,646 isolates were available for statistical analysis. Significantly more isolates of Staphylococcus epidermidis, Staphylococcus aureus, Bacillus, Escherichia, Pseudomonas, Klebsiella, Serratia, Acinetobacter, Alcaligenes, Neisseria, and Candida were recovered from the vented bottle. Significantly more isolates of Corynebacterium, Haemophilus, Flavobacterium, Moraxella, Bacteroidaceae, and Peptostreptococcus were recovered from the unvented bottle.
