Effect of Infection on Metabolism of Dietary Protein in Intestine.

Dietary proteins are linked to the pathogenic Escherichia coli (E. coli) through the intestinal tract, which is the site where both dietary proteins are metabolized and pathogenic E. coli strains play a pathogenic role.

[Construction of ecological security pattern in the agro-pastoral ecotone based on surface humid index: A case study of Hangjin Banner, Inner Mongolia Autonomous Region, China.].

The construction of regional ecological security pattern can effectively protect regional ecological security and achieve regional sustainable development, which has become one of the key topics in landscape ecology. The construction of regional ecological security pattern is particularly important for the Inner Mongolia Plateau, which is characterized by relatively fragile ecological environment and single land cover type. Considering regional natural environment characteristics, five typical ecosystem services, such as food supply, carbon fixation and oxygen release, soil conservation, water yield and habitat conservation, were selected to assess the importance of natural habitats with Hangjin Banner of Inner Mongolia Autonomous Region as a case study area.

High prevalence of Eimeria infection in dairy goats in Shaanxi province, northwestern China.

A survey of dairy goats for infection with Eimeria species of coccidia was conducted in the Shaanxi province, northwestern China between December and November 2010, including Saanen and Guanzhong breeds. A total of 584 fecal samples (250 and 334 from Saanen and Guanzhong dairy goats, respectively) in six farms were collected. Eimeria oocysts were seen in 568 (97.

Seroprevalence of Toxoplasma gondii infection in dairy goats in Shaanxi Province, Northwestern China.

Background: Toxoplasma gondii is an important zoonotic pathogen causing significant human and animal health problems. Infection in dairy goats not only results in significant reproductive losses, but also represents an important source of human infection due to consumption of infected meat and milk. In the present study we report for the first time seroprevalence of T.
