Abstract

Bovine anaplasmosis is an infectious, non-contagious disease caused by the rickettsial pathogen Anaplasma marginale (A. marginale). The organism has a global distribution and infects erythrocytes, resulting in anemia, jaundice, fever, abortions and death. Once infected, animals remain carriers for life. The carrier status provides immunity to clinical disease, but is problematic if infected and naïve cattle are comingled. Knowledge of infection prevalence and spatial distribution is important in disease management. The objective of this study was to assess A. marginale infection in-herd prevalence in Texas cattle using both molecular and serological methods. Blood samples from 11 cattle herds within Texas were collected and analyzed by reverse transcription quantitative real-time PCR (RT-qPCR) and a commercial competitive enzyme-linked immunosorbent assay (cELISA). Samples from experimentally infected animals were also analyzed and RT-qPCR detected A. marginale infection up to 15 days before cELISA, providing empirical data to support the interpretation of herd prevalence results. Herds with high prevalence were located in the north Texas Rolling Plains and west Trans-Pecos Desert, with RT-qPCR prevalence as high as 82% and cEL...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
