paratuberculosis (john’s disease) is infectious and chronically progressive granulomatous disease which affects domestic and wild ruminants. the causative agent is mycobacterium avium paratuberculosis (map), a slow growing mycobactin dependent acid-fast bacillus. we investigated the detection and frequency of map in apparently healthy dromedary and bactrian camels by insertion sequence 900 (is9...

introduction: second national medical sciences olympiad was done in shiraz in august 2010 with aim of indentifying scientifically talented individuals, motivating students and orienting extracurricular activities. this olympiad was done in 3 areas, basic sciences, clinical sciences and management. in clinical sciences, we used tosce (team objective structured clinical examination). in this arti...

Gastrointestinal helminths challenge ruminants in ways that reduce their fitness. In turn, ruminants have evolved physiological and behavioral adaptations that counteract this challenge. Ruminants display anorexia and avoidance behaviors, which tend to reduce the incidence of parasitism. In addition, ruminants appear to learn to self-medicate against gastrointestinal parasites by increasing con...

Listeria (L.) monocytogenes is widely distributed in the environment, but also has the ability to cause serious invasive disease in ruminants and humans. This review provides an overview of listeriosis in ruminants and discusses our insufficient understanding of reservoirs and possible cycling ofL. monocytogenes between animal and human hosts, food and the environment. It indicates gaps in our ...

Ruminants live in various parts of land. Similar cloven hooves assist ruminants in adapting to different ground environment during locomotion. This paper analyzes the general terrain adaptability of the feet of ruminants using kinematics of the equivalent mechanism model based on screw theory. Cloven hooves could adjust attitude by changing relative positions between two digits in swing phase. ...

dear editor clinical environments encounter is an important part of studying medicine (1). patient contact as an integral part of medical education occurs in various formats in the clinical settings (2, 3). during clinical training, medical students may experience high levels of stress, and some may not deal with it well. the abruptness of students’ transition to the clinical setting generated ...

Border disease virus (BDV) is a pathogen primarily infecting sheep and goats; however, infections in cattle, pigs, wild ruminants have also been reported. Interspecies transmission of BDV occurs through close contact among infected animals. In this case report, we describe the detection tonsil, mesenteric ganglia, blood samples from piglets with severe clinical disease. Genetic characterization...

Responses to sugars in dry or liquid formvary from study to study. When fed in proper amounts, sugars should not depress ruminalpH, and there is some evidence that they actuallyhelp toprevent a drop in pH after consuming largemeals of concentrate by maintaining a highernumberoflactate-fermenting bacteria. Adding sugars doesprioritize the need for rumen degraded protein (RDP).we all know, sugars...
