A selective identification medium for Neisseria gonorrhoeae was devised by incorporating antibiotics and a mixture of sugars into a yeast extract agar. The results were compared with those using a standard combined selective/non-selective blood agar medium. Recovery rates of N gonorrhoeae from specimens from 208 patients cultured on both media were comparable, but the selective descriptive medi...

ABSTRACT Current knowledge about microbial injury was derived mostly from studies with bacteria associated with processed foods. Demonstration of injury and repair in phytopathogenic bacteria and its implication on pathogen detection and disease ecology have not been reported. The objective of this study was to investigate the lethal and sublethal effects of acetic acid (AA) on soft-rot Erwinia...

A recently described semisolid blood-free selective motility medium (SSM) (J. Goossens, L. Vlaes, I. Galand, C. Van den Borre, and J. P. Butzler, J. Clin. Microbiol. 27:1077-1080, 1989) was compared with two charcoal-based selective media (charcoal-based selective medium [CSM] and modified charcoal cefoperazone deoxycholate agar [CCDA]), two blood-based media (Skirrow medium [SKM] and CampyBAP)...

Three selective media for differentiation of Klebsiella pneumoniae from Enterobacter aerogenes on the basis of colonial morphology were evaluated. Using methyl violet 2B as a selective agent, strains of K. pneumoniae isolated from urine, fresh water, and fresh produce were tested against other members of Enterobacteriaceae in addition to strains of Aeromonas hydrophila and Pseudomonas aeruginos...

A tetracationic imidazolium-based catenane is reported which selective for bromide over other halides in aqueous media.

In the course of a survey during growing seasons of 2002-04, various fields and pastures in 23 Iranian provinces were sampled. Some 1200 isolates of Fusarium from root, crown, stem and spike of various plants belonging to the family Poaceae were recovered using Nash-Snyder selective medium and purified on potato dextrose agar (PDA). Based on morphological characters, 35 Fusarium species were id...

New and selective Rlk and SA media, combined with cold enrichment at 4 to 5 degrees C, allowed isolation of Mobiluncus species from patients with bacterial vaginosis at higher rates than with conventional cultivation methods. Rlk medium consists of Columbia CNA agar supplemented with peptone, yeast extract, 5% laked rabbit or sheep blood, nalidixic acid, and tinidazole. SA medium consists of Co...

The voltammetric characteristics of bismuth(III)-oxinate in chloroform at the mercury electrode were investigated and a quasi-reversible behavior for Bi(III) oxinate reduction was confirmed. Preceded by the extraction of Bi(III) oxinate in chloroform, differential pulse polarography was developed in the extracts for determination of the trace-bismuth. The linear range of the calibration gra...
