In a preliminary study, the addition of antibiotics was shown to reduce bacterial concentrations in Entodinium exiguum cultures by more than 99% in 4 h, whereas the protozoal population was apparently unaffected. Using this procedure, the growth and amylolytic capability of Entodinium exiguum, in the presence or absence of live bacteria, was studied in vitro. Treatments for Trial 1 were protozo...

The present experiment was designed to estimate the quantitative contribution of rumen protozoa to the total N, conjugated linoleic acid (CLA) and vaccenic acid (VA; trans-11-18 : 1) flow to the duodenum of steers fed two silage diets: control silage (CS) and silage high in water-soluble carbohydrates (HS). Protozoal duodenal flows were estimated using a real-time PCR assay to quantify the gene...

this epidemiological review was carried out to display the magnitude and the geographic distribution of scorpion envenomation in iran with focus on the southwestern region of iran, particularly. the iranian recognized scorpions belonging to two families, including buthidae and scorpionidae. buthidae family consists of 14 genuses, 26 species, and 18 sub-species, while scorpionidae family has thr...

The sharing of habitat by wild and domestic animals may result in pathogen transmission, notably via ectoparasite vectors such as ticks. Interfaces between protected and communal lands constitute sharp transitions between areas occupied by host communities that are extremely contrasted in terms of composition, diversity and density. Empirical characterizations of tick communities and of their v...
