Protective immunity against the ehrlichial pathogen Anaplasma marginale has been hypothesized to require induction of immunoglobulin G2 (IgG2) antibody against outer membrane protein epitopes and coordinated activation of macrophages for phagocytosis and killing. In the present study, cell-mediated immune responses, including induction of IgG isotype switching, were characterized in calves immu...
BACKGROUND Babesia ovis and Theileria ovis are among the important and main etiological agents causing ovine babesiosis and ovine theileriosis, causing severe economic losses among sheep and goats. The aim of the present study was to determine the prevalence and molecular diagnosis of B. ovis and T. ovis in Lohi sheep at Livestock Experiment Station Bahadurnagar, Okara, Pakistan. METHODS The ...
During an 18-mo period (May 2002-November 2003), 10 animals in a herd of 19 reindeer (Rangifer tarandus) at the National Animal Disease Center (NADC) experienced episodes of anemia. Affected animals had histories of weight loss, unthriftiness, occasionally edema of dependent parts and moderate anemia characterized by microcytosis or macrocytosis, hypochromasia, schistocytosis, keratocytosis, ac...
This study aimed to evaluate protection induced by the vaccine candidate B. ovis ΔabcBA against experimental challenge with wild type B. ovis in rams. Rams were subcutaneously immunized with B. ovis ΔabcBA encapsulated with sterile alginate or with the non encapsulated vaccine strain. Serum, urine, and semen samples were collected during two months after immunization. The rams were then challen...
Wallace, W. R. (Louisiana State University, Baton Rouge), and G. T. Dimopoullos. Catalase activity in Anaplasma marginale. J. Bacteriol. 91:309-311. 1965.-Extracts of erythrocytes infected with Anaplasma marginale were found to contain more catalase activity than normal erythrocytic preparations. The increase in catalase activity appeared concurrently with increases in the number of erythrocyte...
Although diverse tick-borne pathogens (TBPs) are endemic to East Africa, with recognized impact on human and livestock health, their diversity and specific interactions with tick and vertebrate host species remain poorly understood in the region. In particular, the role of reptiles in TBP epidemiology remains unknown, despite having been implicated with TBPs of livestock among exported tortoise...
