Finite Purification of Anaplasma marginale: Serologic Inactivity of the Anaplasma Body

American Journal of Veterinary Research, 1977
SUMMARY 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.

Infection capacity of Trypanosoma vivax experimentally inoculated through different routes in bovines with latent Anaplasma marginale.

Experimental parasitology, 2020
The aim of the present study was to compare the infection capacity of Trypanosoma vivax experimentally inoculated through different routes in calves naturally infected with latent Anaplasma marginale.

An Anaplasma centrale DNA probe that differentiates between Anaplasma ovis and Anaplasma marginale DNA

Veterinary Microbiology, 1991
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.

Identification of Anaplasma marginale in long-eared hedgehogs (Hemiechinus auritus) and their Rhipicephalus turanicus ticks in Iran.

Ticks and Tick-borne Diseases, 2020
Hedgehogs play a role in the eco-epidemiology of parasites, viruses and bacteria of veterinary and medical importance. In Europe, hedgehogs have been found infected with tick-transmitted Anaplasma phagocytophilum and A. marginale. In this study blood and

Antigenic variation in Anaplasma marginale

Trends in Parasitology, 2001
Many 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 Parasitology
The 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, 1968
SUMMARY 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.

Pentaplex PCR assay for rapid differential detection of Babesia bigemina, Theileria annulata, Anaplasma marginale and Trypanosoma evansi in cattle.

Biologicals (Print), 2019
A multiplex PCR (mPCR) assay for simultaneous detection and differentiation of four major haemoparasites in crossbred cattle was established using parasite specific genomic DNA and four sets of primer pairs targeting AMA-1, Tams1, MSP5 and VSG genes of ...

Development of a recombinant Anaplasma marginale DNA probe

Veterinary Microbiology, 1990
An Anaplasma marginale DNA probe has been developed by using an improved method for the isolation of genomic DNA. Purified genomic A. marginale DNA from the St. Croix isolate was partially digested with Sau 3A1 into fragments (greater than or equal to 5.0 kb). The restriction fragments were cloned using standard techniques in the pBR322 vector and used
