Paratuberculosis, a chronic and sometimes fatal disease of ruminants, is caused by Mycobacterium avium subsp. paratuberculosis (MAP). In this study, we examined paratuberculosis cases among 2-4-year-old dairy cows at farms in Shandong Province, China. Paratuberculosis cases were
A paired feeding experiment was conducted to investigate if reduced food intake is a reason for the body weight loss previously observed in severe combined immunodeficient beige (SCID bg) mice infected with Mycobacterium paratuberculosis. Mice were paired on the basis of age, litter and sex. One of
The effect of infection with Mycobacterium avium ssp. paratuberculosis (MAP) on slaughter weight and slaughter value of dairy cows was evaluated. Two data sets were analyzed: 1) recordings from 1,031 cows from herds in a pilot study to control MAP infections, and 2) recordings from 36,455 cows from
Paratuberculosis in ruminants is characterized by oral ingestion of Mycobacterium avium subsp. paratuberculosis (MAP), followed by a long incubation period during which time MAP is able to survive within the host’s macrophages. Initially the infection is held in check by the host’s cell-mediated
Crohn's disease is a chronic enteritis of humans that affects the gastrointestinal tract, especially the terminal ileum, cecum and colon. The etiology of this disease is still unknown but seems to be multifactorial. There are reports about the potential link between Crohn's disease in This article describes the histopathology of grossly normal mesenteric lymph nodes (MLNs) of New Zealand farmed red deer (Cervus elaphus). Eighty MLNs were sourced from 10 deer from 5 North Island herds and 5 South Island herds classified as low risk and high risk of Mycobacterium avium subspecies
Four cattle had chronic diarrhea and had lost weight but were not anorectic or dehydrated. A diagnosis of eosinophillic enteritis was made on the basis of a combination of clinical and histopathologic findings and exclusion of other diseases. Eosinophilia and hypoalbuminemia were not detected in CBC
