Immunoelectrophoresis revealed in phenol extracts from S. faecalis and S. faecium a mixture of free and lipid-bound teichoic acids, both reactive with Group D antisera. In phenol extracts from S. suis only lipid-bound teichoic acid, also reactive with Group D antiserum, was seen. This difference probably accounts for the low yield of Group D antigen from S. suis as compared with S. faecalis and...

The results of four field surveys in Senegal are reported. 1. A snail survey in various parts of the Senegal River Basin, including the Senegal River, temporary rain-fed pools, swamps, irrigation canals and drains, ricefields and Lac de Guier was carried out. Three species of snails were commonly found: Bulinus guernei was the most common, occurring in permanent habitats, Bulinus senegalensis o...

PURPOSE The aim of this report is to present a previously unreported causative organism associated with brown-pigmented hypopyon in a patient with endophthalmitis. METHODS This is a retrospective case report which includes clinicopathologic correlations. RESULTS Vitreous cultures demonstrated Streptococcus bovis infection resulting in a brown-pigmented hypopyon, with uveal pigment found int...

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.

A prospective study was conducted to evaluate the radiometric detection of group D and viridans streptococci in blood, using three media preparations, Bactec 6A and 6B isotonic media and 8B hypertonic medium. All enterococci tested were detected by the 6A and 6B media. However, the 6A medium failed to detect 76% of the Streptococcus bovis isolates and 57% of the viridans streptococci, whereas a...

Streptococcus equinus (Streptococcus bovis) HC5 is a bacteriocinogenic lactic acid bacterium with simple growth requirements. The draft genome sequence of S. equinus HC5 consists of 1,846,241 bp, with a G+C content of 37.04%. In silico analysis indicated that S. equinus HC5 might be useful to control bacteria that are detrimental to livestock animals.

The economic importance of the trematode Schistosoma bovis in African livestock has justified the development of a specific vaccine. Administered preventively to sheep, rSb28GST--the only molecule cloned from S. bovis which has demonstrated vaccine potentialities in goats and cattle--reduced the mean worm burden in vaccinated animals and improved their health status compared with that of non-va...

anaplasma bovis is a leukocytotropic agent of bovine anaplasmosis and there is no available information about molecular study on this agent in cattle of iran. in this study a total 150 cattle blood samples were collected from central part of iran. the presence of a. bovis examined using light microscopic detection and species-specific nested polymerase chain reaction (nested-pcr) based on 16s r...
