The speckled kingsnake, Lampropeltis holbrooki Stejneger (=L. getula holbrooki) is a medium sized colubrid that ranges from southern Iowa south through to the Gulf of Mexico (Conant and Collins 1998). In Arkansas, L. holbrooki can be found statewide where it inhabits forested woodlands and rocky hillsides in the Interior Highlands (Ozark and Ouachita mountains) to floodplains and swampy wetland...

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...

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 were added...

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...

Fecal samples were collected from 655 passerine birds representing 190 species from 13 collection sites in Guyana, Ecuador, Peru, and Argentina from August, 1990 August, 1997. The fecal samples were stored in 2.5% K2Cr2O7 and examined for coccidian oocysts within six weeks after collection. The overall prevalence of coccidian parasites in the samples was 20.9% (137/655). The one-sample test of ...

intestinal parasitosis has been a major public health problem in iran. it is necessary to evaluate an up-date data in this regard to be used by local authorities. serum ige determinations and coproparasitological analyses were conducted on 1200 individuals in city of ghaemshahr, mazandaran province, northern iran. a total of 1200 subjects were taken stool samples for three days consecutively. t...
