Alkaline phosphatase (ALP) is an enzyme present in intestinal mucosa, bile, bone and renal tubule cells. Bile acids have been shown to decrease ALP activity from bone and kidney but not those from intestinal origin. This action can be mimicked in serum and peritoneal fluid samples by the use of...
The digestion responses and degradation of ergovaline and production of
lysergic acid in the rumen of sheep offered Neotyphodium coenophialum-infected
tall fescue straw at two ergovaline levels was investigated. Six crossbred wethers
(56 +1- 3 kg BW) were randomly assigned to one of two treatment groups in a
cross-over design....
Mycobacterium avium is a ubiquitous environmental organism found in water and soil. It can cause disease in patients with pre-existing pulmonary conditions, immunocompromised patients with the most prevalent being AIDS patients, as well as apparently healthy people. Studies have indicated that, upon macrophage uptake, Al. avium prevents phagosome-lysosome fusion, thus...
Suspensory apparatus breakdown and hyperextension of the metacarpophalangeal and metatarsophalangeal (fetlock) joints is a common condition in the llama and has been observed in llamas of all ages. Llama breeders refer to the condition as "down in the pasterns" or "down in the fetlocks." The condition can result in debilitating...
Recent developments in the field of clinical echocardiography allow the ultrasonographer to objectively quantify both regional and global myocardial function. Regional deformation (Strain) and deformation rate (Strain Rate) are novel indices of ventricular function that can be estimated non-invasively by ultrasonographic interrogation of the heart. Deformation Imaging (DI)represents a family...
Bovine respiratory syncytial virus (BRSV), bovine viral diarrhea (BVD) and bovine parainfluenza virus Type 3 (BPI3) are ubiquitous respiratory pathogens of cattle, which contribute to causation of bovine respiratory disease complex. As these respiratory viral pathogens cause very similar clinical symptoms, differential diagnosis of the pathogens is required in one...
