Identification of anaerobes recovered from clinical samples is complicated by the fact that certain gram-positive anaerobes routinely stain gram negative; Peptostreptococcus asaccharolyticus, Eubacterium plautii, Clostridium ramosum, Clostridium symbiosum, and Clostridium clostridiiforme are among the nonconformists with regard to conventional Gram-staining… (More)
Methanol fixation of Gram-stained smears was compared to heat fixation. Smears were prepared in duplicate from direct clinical specimens, blood culture bottles, and bacterial colonies. Results from this study show that methanol fixation is superior in every instance to heat fixation. The morphology of bacteria and tissue cells was not distorted, little or… (More)
Table 1. Average colony size of the six quality control strains: Anaerobic chambers and anaerobic jars are used to provide ancomparison of four methods for cultivating anaerobic bacteria. aerobic conditions required to cultivate anaerobic bacteria. All operations and manipulations of cultures can be carried out inside Setup: incubation the anaerobic… (More)
A 5-laboratory study was performed that used the National Committee for Clinical Laboratory Standards (NCCLS) reference agar dilution method with 3 media formulations to determine whether the use of different media would affect minimum inhibitory concentration (MIC) results. Wilkins-Chalgren, Brucella-based blood agar (BRU), and Wilkins-Chalgren agar plus… (More)
A rapid Tween 80 hydrolysis test for mycobacteria utilizing gas-liquid chromatography is described. The test requires 1 h of incubation followed by simple extraction and chromatography of nonderivatized oleic acid.
A multilaboratory study compared the growth of 30 fastidious anaerobes, using 5 different agar media: Wilkins-Chalgren (WC), WC with either whole or laked sheep blood, and Brucella supplemented with vitamin K(1) and hemin and either laked or whole sheep blood. The media were compared for quality and quantity of growth. Experiments were conducted either… (More)
A rapid and sensitive urease test for mycobacteria utilizing a cumulative radiometric technique is described. Definitive results were obtained within a 30-min incubation period. The procedure is simple and economical. Technical time involved is no greater than in conventional procedures.
A liquid scintillation procedure for the catabolism of D-[1-14C]glucose and [U-14C]maltose by pathogenic Neisseria was tested. Definitive results were obtained within a 30-min incubation period.
The investigation demonstrates the usefulness of a radiometric urease test in the rapid detection of Haemophilus influenzae in cerebrospinal fluid specimens. The test is simple and economical to perform and results are obtained within a one hour incubation period.
A small portable chamber for the recovery of anaerobic bacteria is described. This rigid chamber is constructed of clear acrylic with dimensions of 30 inches (ca. 76.2 cm) wide, 18 inches (ca. 44.7 cm) deep, and 18 inches (ca. 44.7 cm) high. Conventional bacteriological techniques can be used inside the chamber to efficiently isolate strict anaerobic… (More)
