Molecular characterization of Anaplasma marginale based on the msp1a and msp1b genes.
Veterinary Microbiology, 2021Anaplasma marginale is an intracellular rickettsial bacterium causing anaplasmosis in ruminants. A. marginale is transmitted biologically by ticks and mechanically by blood-sucking vectors.

A Study of the Immunological Relationship of Anaplasma Marginale and Anaplasma Centrale
Research in Veterinary Science, 1967SUMMARY A total of 112 experimental cases of anaplasmosis using Anaplasma marginale (from 3 sources) and Anaplasma centrale, in splenectomized calves, non-splenectomized calves, yearlings and adult cattle, have been studied to measure the immunological relationship of these anaplasms.

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.

Anaplasma marginale is the rickettsial agent of anaplasmosis, a tick-borne disease, which affects cattle and other ruminants in tropical and subtropical areas of the world, and causing huge economic losses because of decreasing meat and milk production ...

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.

Abstract Objective—To determine whether sequelae of infection differed among single versus double infection with Anaplasma phagocytophilum or Anaplasma marginale, with and without tick salivary extract, in cattle. Animals—Eighteen 13-month old steers. Procedures—Treatment groups of 3 cattle each included A marginale inoculated ID followed on day 35 by ...

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

Development of a recombinant Anaplasma marginale DNA probe
Veterinary Microbiology, 1990An 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
