The etiology of Crohn's disease in humans is largely unknown. Clinical signs of Crohn's disease partly resemble the clinical picture of Johne's disease in ruminants caused by Mycobacterium avium subsp. paratuberculosis. Because of the high prevalence of these bacteria in (products of) ruminants and their remarkable thermostability, concern has been raised about the possible role of these bacter...

background and purpose: basic medical sciences, not only in its traditional form as basic sciences, but also in its modern forms like biotechnology and genetics has indicated a highly applicable potential in the prevention, diagnosis, and treatment of illnesses. therefore it is essential to improve basic sciences education quality, and because clinical students are in direct contact with medica...

introduction: lack of coordination between academic education and their application in the workplace is a common gap between theory and practice. this issue of concern has been discussed among planners of medical education. in this study, the attitude of medical students, externs and interns, was evaluated about the clinical applications of bacteriology. methods: one hundred and fifty four medi...

Pestiviruses infect a wide range of domestic, captive and free-living ruminants. Among domestic livestock, Border disease virus is a well recognised cause of an important congenital disease of sheep in virtually all sheep-rearing countries of the world. The clinical signs, pathogenesis, diagnosis, epidemiology and control of this disease are described in detail. One natural outbreak of Border d...

background: ticks are the main vectors for transmission of different pathogens to human and animals. this survey was performed to find out distribution of ticks, which infested the domestic ruminants in yazd province, central iran during year 2008-2009. methods: a total number of 30 villages from both mountainous (20%) and plateau (80%) regions of the province were selected randomly. ticks were...

Peste des petits ruminants (PPR) is a viral disease which primarily affects small ruminants, causing significant economic losses for the livestock industry in developing countries. It is endemic in Saharan and sub-Saharan Africa, the Middle East and the Indian sub-continent. The primary hosts for peste des petits ruminants virus (PPRV) are goats and sheep; however recent models studying the pat...

background and purpose: future generalists require in depth exposure to primary care practice and the opportunity to work with successful generalist role models.changes in hospital practice, patient availability, increased student numbers and their expectations and a redefinition of expected learning outcomes are changing the emphasis of clinical teaching away from traditional inpatient setting...

Several distinct molecules involved in maternal-conceptus interactions have been discovered in ruminants. Among these are two families of immunoregulatory molecules that represent genes that have undergone evolution to perform a function distinct from that of the ancestral gene. Interferon-tau (IFN-tau) is a product of the trophoblast that retains its antiviral activity and other functions char...

Following a request from the European Commission, a scientific opinion was prepared by EFSA‘s Animal Health and Welfare Panel to determine the magnitude, distribution, impact and significance of infection and disease in domestic ruminants and humans, risk factors for the maintenance (in domestic ruminant populations) and spillover (from these populations to humans) of Coxiella burnetii (the cau...
