B complex vitamins play an important role in the metabolism of carbohydrates, proteins and fats. The aim of this study was to determine the effects of B complex vitamins administered by exogenous route on rumen protozoa, hematological and blood biochemical parameters in clinically healthy cattles. Thirty cattles aged between 6 to 18 months, and breeding in Afyonkarahisar Province and surroundin...

Charon ventriculi comprised over 30% of the total protozoa observed in rumen contents of a Flamenga cow fed Rhodes grass hay (Chloris gayana). Both percentage of composition and concentration decreased markedly when concentrate was added to the ration or the animal was fed in pasture. Although C. ventriculi is classified as a holotrich, concentrations of this species in the rumen appear to foll...

The Formosan subterranean termite; Coptotermes formosanus is nutritionally dependent on the complex and diverse community of bacteria and protozoa in their gut. Although, there have been many studies to decipher the taxonomic and functional diversity of bacterial communities in the guts of termites, their bacteriophages remain unstudied. We sequenced the metavirome of the guts of Formosan subte...

T HE role of rumen protozoa in ruminant metabolism has received increasing attention during the past few years. Increased rates of gain by lambs containing protozoa compared to protozoa-free lambs were reported by Abou Akkada and el-Shazly (1964) and Yoder et al. (1964), who demonstrated that certain rations are more readily digested by faunated than by defaunated lambs. Greater rumen ammonia c...

Recent studies have identified a phenomenon in which ciliated protozoa engulf Salmonella and the intra-protozoal environment hyperactivates virulence gene expression and provides a venue for conjugal transfer of antibiotic resistance plasmids. The former observation is relegated to Salmonella bearing the SGI1 multiresistance integron while the latter phenomenon appears to be a more generalized ...
