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...

Whole chromosomal DNA probes were used to identify clinical isolates of Mycobacterium tuberculosis, Mycobacterium avium complex, and Mycobacterium gordonae. The probe for M. tuberculosis was prepared from Mycobacterium bovis BCG, which has been shown to be closely related to M. tuberculosis. A probe for the M. avium complex was prepared from three strains representing each of the three DNA homo...

conclusions subcutaneous nodules in the absence of a local reaction at the site of bcg vaccination may be the sole manifestation of disseminated bcg disease. case presentation we report on an 11-months-old boy with prolonged fever and diffuse hyperpigmented subcutaneous nodules. due to lymphopenia, oral thrush and severe adverse reaction to bcg vaccination, the possibility of primary immunodefi...

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...

b a ckground: there is a little or no data available on the natural babesia bovis ( b . bovis ) infection in water buffaloes( buba l u s bubalis ) comparing to the available one for cattle. this study was conducted to investigate the natural b. bovis infection in water buffaloes in comparison to crossbred cattle under field conditions in egypt. m e t hods: a total of 35 buffaloes and cattle wer...

in most countries, tuberculosis caused by mycobacterium bovis is mainly a disease of cattle but can infect buffalos too. the disease can be controlled successfully by mean of a test-and-slaughter program. in iran test-and-slaughter program has started since 1971 and prevalence of bovine tuberculosis reduces from 5% to less than 0.12% in recent years. in western azarbaijan, north west of iran, t...

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...

mastitis, inflammatory disease of mammary glands, can be caused by various microorganisms. many antimicrobial agents have been evaluated to combat the causative agents. development of resistance in pathogens against conventional antibiotics may be high; hence at present study in vitro efficacy of a new fluoroquinolone antibiotic (marbofloxacin) against isolated pathogens from clinical mastitis ...
