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

Kinetics of the Antibody Response to Anaplasma Marginale Infection
Journal of Infectious Diseases, 1966A pattern of sequential synthesis of particular molecular species of immunoglobulins has been described in the response of several animal species to nonviable antigens such as proteins, polysaccharides, and inactivated bacteria. With few exceptions early, exclusive 7M globulin antibody synthesis is augmented or replaced by 7G antibody after periods ...

Recrudescence of Anaplasma marginale Induced by Immunosuppression with Cyclophosphamide
American Journal of Veterinary Research, 1981SUMMARY Eight doses of cyclophosphamide (5 mg/kg), at 2-day intervals between doses, were administered iv to Anaplasma-carrier splenectomized calves. Significant decreases in serum immunoglobulins, diminished complement-fixing antibody response, and transitory leukopenia were associated with the treatment.

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

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.

Veterinary Immunology and Immunopathology, 1991
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

Evaluation of the transmission of Anaplasma marginale by Amblyomma tonelliae
Veterinary ParasitologyThis study aimed to evaluate A. marginale transstadial (TST) and transovarial transmission (TOT) by Amblyomma tonelliae through vector competence assays and analysis of natural infection in free-living ticks. This three-host tick species was chosen as model because it is a usual parasite of cattle in all their parasitic stages, making them potential ...

Cryogenic Preservation of Anaplasma marginale with Dimethyl Sulfoxide
American Journal of Veterinary Research, 1972SUMMARY Different concentrations of dimethyl sulfoxide (dmso) were investigated to determine the optimal concentration which would prevent lysis of bovine erythrocytes when subjected to rapid freezing and thawing. Results indicated 4 M dmso was the optimal concentration.
