background: l-glutamic acid is one of the major amino acids that is present in a wide variety of foods. it is mainly used as a food additive and flavor enhancer in the form of sodium salt. corynebacterium glutamicum (c. glutamicum) is one of the major organisms widely used for glutamic acid production. methods: the study was dealing with immobilization of c. glutamicum and mixed culture of c. g...

objective: erythrasma is a chronic superficial infection of the intertriginous areas. most laboratories use methylene blue stain and 10% koh smear to identify corynebacterium minutissimum (c. minutissimum) by direct observation of filamentous bacilli. occasionally atypical forms can be seen that create problems in diagnosis. this study aims to use the polymerase chain reaction (pcr) method in o...

Ten isolates each of two different bacterial species isolated from the surface of a smear-ripened cheese were found to exhibit many characteristics of the genus Corynebacterium. The isolates were Gram-positive, catalase-positive, non-spore-forming rods that did not undergo a rod/coccus transformation when grown on complex media. Chemotaxonomic investigation revealed that the strains belonged un...

The genus Corynebacterium represents one of the earliest described bacterial genera. Recently, we can observe an increasing number of publications describing different incidents of infections, where species of Corynebacterium are isolated as the etiological factor[1-6]. This genus was originally proposed for the causative organism of Corynebacterium diphtheriae (Lehmann and Neumann, 1896) for d...

The in vitro activities of ABT-773 were evaluated against 15 Listeria monocytogenes strains and 196 coryneform bacteria isolated from clinical samples. One hundred percent of the L. monocytogenes strains were inhibited by </=0.015 micro g of ABT-773/ml. MICs of ABT-773 ( micro g/ml) at which 50% of the isolates tested were inhibited (MIC(50)s) and MIC(90)s for other organisms were 0.125 and 0.5...

Corynebacterium jeddahense sp. nov., strain JCB(T), is the type strain of Corynebacterium jeddahense sp. nov., a new species within the genus Corynebacterium. This strain, whose genome is described here, was isolated from fecal flora of a 24-year-old Saudi male suffering from morbid obesity. Corynebacterium jeddahense is a Gram-positive, facultative anaerobic, nonsporulating bacillus. Here, we ...

Three glutamic-acid-producing coryneform strains were isolated from soil and vegetable samples. Chemotaxonomic investigations indicated that these strains belonged to the genus Corynebacterium. Phylogenetic studies, based on 16S rDNA analysis, demonstrated that the three strains formed a distinct cluster within the genus Corynebacterium and that their nearest relatives were Corynebacterium glut...

In an attempt to screen out new potent antimicrobial substances producing bacteria, Corynebacterium kutscheri NB-1 and Corynebacterium xerosis NB-2 were isolated and were found antagonistic to bacteria and fungi. Antimicrobial substances production of the bacterial strains was greatly influenced by variation of carbon sources. Galactose and glucose strongly enhanced the antimicrobial activity o...

The susceptibilities of 265 strains of Corynebacterium species and other non-spore-forming gram-positive bacilli to 18 antimicrobial agents were tested. Most strains were susceptible to vancomycin, doxycycline, and fusidic acid. Corynebacterium jeikeium and Corynebacterium urealyticum were the most resistant organisms tested. Resistance to beta-lactams, clindamycin, erythromycin, azythromycin, ...
