S TUDIES by Appleby et al. (1956), Gutierrez and tlungate (1957), Eadie et al. (1959) and Eadie and Hollson (1962) indicated that ciliate protozoa normally inhabiting the rumen exerted considerable influence upon end products of rumen fermentation and upon tureen bacterial populations. The full significance of protozoa to the nutrition of cattle and sheep is not clear. However, Christiansen et ...

introduction: intestinal parasites have world wide prevalence and are considered to be as one of the leading hygienic and economic problems in the world. it can be said that there is nowhere in the world without parasitic infestations. the present study was conducted to determine the prevalence of intestinal parasites in patients referring to yazd central laboratory in 2000-2002. methods: the p...

A study of diseases of the bovine lungs was carried out in Akwa Ibom State Niger a between (1999 – 2002). A tota of 5,369 cattle were slaughtered with n the study period out of wh ch, 459 (8.5 %) lungs were condemned. Tuberculosis accounted for 183(39.921), represent ng 3.4 % of the to al cat e popu at on. This was closely followed by Pneumonia, which was 180(39.2 %), represent ng 3.4 % of th s...

The major aim of this study was to compare the morphology and activity of rumen protozoa of Khuzestan water buffalo and Holstein cow using in vitro digestibility and gas production parameters of steam treated sugarcane pith. Rumen fluid obtained from two buffalo and cow steers fed the same diet, 30:70 concentrate: forage. To separate rumen protozoa, antibiotic solution and fungicides w...

A previously described mathematical model, that stimulates the metabolic activities of rumen bacteria and protozoa, was used to examine the contribution of protozoa to neutral-detergent fibre (NDF) degradation in the rumen of cattle. Comparisons between predicted and experimentally observed NDF degradation showed general agreement. Further simulations were performed with diets containing variab...

Protozoan programmed cell death or apoptosis is an important factor in the survival of the parasite and its pathogenicity. The most amazing aspect of protozoan cell death is in its molecular architecture. To date, protozoa lack most of the components of the highly complex cell death machinery studied in multicellular organisms. Hence the unique apoptotic machinery in protozoa can be exploited f...

Two rumen protozoa vaccine formulations containing either whole fixed Entodinium or mixed rumen protozoa cells were tested on Merino sheep with the aim of decreasing the number and/or activity of protozoa in the rumen. Negative control (no antigen) and positive control (Tetrahymena corlissi antigens) treatments were also included in the experiment. Blood and saliva were sampled to measure the s...
