The potential of tannins from 21 medicinal and aromatic plant leaves as antimethanogenic additives in ruminant feeds was investigated. The effect of tannin from these leaves on rumen fermentation parameters, protozoa population and methanogenesis was studied by incubating the samples [200?mg dry matter (DM)] without and with polyethylene glycol (PEG)-6000 (400?mg DM) as a tannin binder during 24-h incubation in the in vitro Hohenheim gas method.

This study investigates the effects of Terminalia chebula Retz. meal supplementation on rumen fermentation and methane (CH4 ) production by using an in vitro gas technique. The experimental design was a completely randomized design (CRD) and the dietary treatments were T. chebula supplementation at 0, 4, 8, 12, 16 and 20?mg with 0.5?g of roughage and concentrate ratio at 60:40. The results revealed that cumulative gas production (96?h of incubation) were higher (P?<?0.01) with T. chebula supplementation at 12, 16 and 20?mg than other treatments.

Using nonperoxidic analogs of artemisinin and OZ277 (RBx11160), the strong in vitro antiplasmodial activities of the latter two compounds were shown to be peroxide bond dependent. In contrast, the weak activities of artemisinin and OZ277 against six other protozoan parasites were peroxide bond independent. These data support the iron-dependent artemisinin alkylation hypothesis.

The present study was carried out to determine the factors causing the disappearance of introduced Salmonella enteritidis, Staphylococcus aureus, and Vibrio cholerae in natural river water. When large numbers of the above organisms (final level 10(7)-10(8) CFU per ml) were added to river water, the decline of their numbers coincided with increasing numbers of protozoa. Furthermore, their survival was improved dramatically if the river water was amended with a eucaryote inhibitor.
