Purpose. Up to 30% of international travelers are affected by travelers' diarrhea (TD). Reliable data on the etiology of TD is lacking. Sufficient laboratory capacity at travel destinations is often unavailable and transporting conventional stool samples to the home country is inconvenient. We evaluated the use of Hemoccult cards for stool sampling combined with a multiplex PCR for the detectio...

in this expriment, the effect of different levels of ziziphus zizyphus(zz) (0, 30 or 60 mg) on fermentation parameters, total protozoa population  and three sub family of protozoa  entodiniinae, ophryscolecinae, diplodiniinae and family of isotrichdaeandmethane gas production was assessed using in vitro method and a completely randomized design. the rate of gas production for the insoluble frac...

eight male lambs each aged approximately 11 months and having a body weight of 32.5 ± 2.5 kg were selected as experimental samples in the ongoing experiment. for the supplemented group, monensin was fed at 22 mg/lamb per day. relationships between dietary characteristics and fecal as well as urinary nitrogen losses were examined using data from the two treatments. microbial n production was est...

Myocarditis has been described during and after a wide variety of infectious agents: viral, rickettsial, bacterial, protozoal, and metazoal diseases may cause cardiac inflammation. We report a case of toxoplasma myocarditis in a young healthy man.

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...

Protozoa-associated methanogens (PAM) are considered one of the most active communities in the rumen methanogenesis. This experiment investigated whether methanogens are sequestrated within rumen protozoa, and structural differences between rumen free-living methanogens and PAM. Rumen protozoa were harvested from totally faunated sheep, and six protozoal fractions (plus free-living microorganis...

Based on our previous finding that certain cembranoid diterpenes possess selective toxicity against protozoan pathogens of tropical diseases such as Trypanosoma and Plasmodium, we have subjected a series of 34 cembranes isolated from soft corals living in the Vietnamese sea to an in vitro screening for anti-protozoal activity against Trypanosoma brucei rhodesiense (Tbr), T. cruzi (Tc), Leishman...
