Under the poor hygienic conditions, tick-borne pathogens cause severe economic losses to the cattle industry. The current study investigated the presence of Theileria annulata, Babesia bigemina, and Anaplasma marginale, the most relevant tick-borne ...

Ultrastructure of Anaplasma marginale After Freeze-Fracture
American Journal of Veterinary Research, 1975SUMMARY Stained thin sections and freeze-fractured replicas of Anaplasma marginale-infected bovine erythrocytes were examined by electron microscopy. Freeze-fracture replication not only verified basic Anaplasma ultrastructure, but also allowed visualization of structures not previously reported. Because of the partial 3-dimensional views obtained with

Radioimmunoassay for Anaplasma marginale antibodies in cattle
American Journal of Veterinary Research, 1988SUMMARY A radioimmunoassay is described for use in the detection of Anaplasma marginale antibodies in cattle sera. Optimal sensitivity and specificity were obtained by using 2 antigens, an A marginale antigen and a rbc antigen (obtained before infection was established) from the same calf. In addition, sera were preabsorbed with rbc from healthy cattle

High titered antibody from rabbits immunized with Anaplasma centrale or from cattle recovered from A. centrale infection bound predominantly to several 33-36 kDa polypeptides present in both A. centrale and the Israel-NT isolate of Anaplasma marginale. High titered bovine antibody against the Israel-NT isolate of A. marginale also reacted predominantly

Finite Purification of Anaplasma marginale: Serologic Inactivity of the Anaplasma Body
American Journal of Veterinary Research, 1977SUMMARY Anaplasma bodies finitely purified by affinity chromatography to eliminate all traces of erythrocytic stromata were not agglutinated by serum from calves having acute anaplasmosis. The stromata which were associated with the anaplasma bodies were also finitely purified and agglutinated with such serum.

An Anaplasma centrale genomic library was constructed in pUC13. Two clones pAC5 and pAC137 hybridising to A. centrale and A. marginale DNA were isolated from this library. One of these, pAC5, also hybridised to DNA from A. ovis. The total insert of pAC5 was subcloned into pBR322. This subclone, pAC5-12, could detect 1 ng A.

Antigenic variation in Anaplasma marginale
Trends in Parasitology, 2001Many parasitic organisms use antigenic variability to evade specific immune responses of the host. Antigenic diversity and genotypic differences between parasite clones, antigenic variation and phenotypic variation within a single clone are the most prominent mechanisms that have evolved during evolution.

Analysis of management factors influencing Anaplasma marginale transmission
Veterinary ParasitologyThe aim of this study was to identify factors that play a key role in the epidemiology of bovine anaplasmosis by adapting a model primarily developed for cattle babesiosis. A cross-sectional observational study was conducted to study the proportion of calf herds in endemic stability/instability for A. marginale in a semi-arid area of Argentina.

Chemotherapy of Experimental Anaplasma Marginale Infections
British Veterinary Journal, 1968SUMMARY α-ethoxyethylglyoxal dithiosemicarbazone effectively inhibited multiplication of Anaplasma marginale in experimentally infected splenectomized calves and intact, susceptible steers. Mortality in splenectomized calves, treated during the patent rise of acute infection with 50 mg./kg. orally or 10 mg./kg.
