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...

Gram stains were performed on strains of Actinomyces bovis, Actinomyces viscosus, Arthrobacter globiformis, Bacillus brevis, Butyrivibrio fibrisolvens, Clostridium tetani, Clostridium thermosaccharolyticum, Corynebacterium parvum, Mycobacterium phlei, and Propionibacterium acnes, using a modified Gram regimen that allowed the staining process to be observed by electron microscopy (J. A. Davies,...

Abstract The main etiologic agent of tuberculosis (TB) in livestock is Mycobacterium bovis; human TB cases caused by M. bovis are rare. Analysis a outbreak polyresistant involving and sympatric sheep Spain suggests local circulation drug-resistant strains among livestock.

background and objectives: mycobacterium tuberculosis complex is consisted of homogenous organisms. they are slowly growing mycobacteria and their isolation and identification are difficult and time consuming. differentiation of mycobacterium bovis, causative mammalian tuberculosis, from other members of mycobacterium tuberculosis complex is very important in epidemiology and control of disease...

Quarter milk samples from 51 purebred (Angus, Polled Hereford, and Simmental) and 69 crossbred (Angus x Simmental x Charolais three-way cross) beef cows were collected aseptically at three times during lactation to determine the prevalence of intramammary infection, milk somatic cell counts (SCC), and effects of infection on calf weight gain. Quarter infection prevalence was 13.1, 14.9, and 27....

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 ...

A longitudinal study was undertaken in infants living in the Maela refugee camp on the Thailand-Myanmar border between 2007 and 2010. Nasopharyngeal swabs were collected monthly, from birth to 24 months of age, with additional swabs taken if the infant was diagnosed with pneumonia according to WHO clinical criteria. At the time of collection, swabs were cultured for Streptococcus pneumoniae and...

The recently described property of bacteria to bind to human lymphocytes was used to distinguish between normal and chronic leukemic lymphocyte (CLL) populations. Strains of the following bacteria were used in this study: Arizona hinshawii, Escherichia coli strains 1 and 2, Bacillus globigii, Brucella melitensis, Corynebacterium diphtheriae strains 1 and 2, Corynebacterium xerosis, Sarcina lute...

PhoP is part of the two-component PhoPR system that regulates expression virulence genes Mycobacteria. The goal this work was to elucidate role in mechanism Mycobacterium bovis, causative agent bovine tuberculosis, displays upon stress. An analysis gene and acidic growth curves indicated M. bovis neutralized external environment by inducing secreting ammonia. We found essential for ammonia prod...

chorioptes bovis is a mite found on the skin of cattle , horse, sheep, goat , camel and wild ruminant. in cattle the root of tail is frequently affected and if untreated the condition may spread to the other parts of the body. c. bovis isolated for the first time from eight dairy cattle 3-7 years old around sharifabad , tehran province.
