The natural history of Anaplasma marginale

Veterinary Parasitology, 2010
The intracellular pathogen Anaplasma marginale (Rickettsiales: Anaplasmataceae), described by Sir Arnold Theiler in 1910, is endemic worldwide in tropical and subtropical areas. Infection of cattle with A. marginale causes bovine anaplasmosis, a mild to severe hemolytic disease that results in considerable economic loss to both dairy and beef ...

In vivo Endothelial Cell Infection by Anaplasma marginale

Veterinary Pathology, 2007
Anaplasma marginale has recently been shown to infect endothelial cells in vitro, but it remains unknown as to whether endothelial infection also occurs in vivo.

Bovine Fetal Response to Anaplasma marginale

American Journal of Veterinary Research, 1971
SUMMARY Blood contaning 70% erythrocytes infected with Anaplasma marginale was inoculated into a 100-day-old bovine fetus in utero. At 41 days after inoculation, the fetus was removed from the cow by cesarean section. The fetal serum reacted positively (4+) to the complement-fixation test.

Anaplasma marginale in tick cell culture

American Journal of Veterinary Research, 1989
SUMMARY Anaplasma marginale was propagated in a tick cell line derived from Dermacentor variabilis embryos. The rickettsial organism was identified and monitored in culture by transmission electron microscopy and the indirect immunofluorescence technique, using specific monoclonal antibodies.

Differential extraction of antigens of Anaplasma marginale

American Journal of Veterinary Research, 1988
SUMMARY Strain-, group-, and genus-specific antigens of the Florida isolate of Anaplasma marginale had different solubilities in zwitterionic, nonionic, and anionic detergents. On the basis of their solubility in nonionic detergent, antigens were grouped into 3 classes: (i) a 108-kilodalton (kD) group-specific antigen and a series of poorly defined ...

Radioimmunoassay for Anaplasma marginale antibodies in cattle

American Journal of Veterinary Research, 1988
SUMMARY 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

Anaplasma marginale in Bovine Erythrocyte Cultures

American Journal of Veterinary Research, 1980
SUMMARY Bovine erythrocytes infected with Anaplasma marginale were standardized with normal bovine erythrocytes at 1.4% and 3.5% parasitemia and cultured under low oxygen pressure at 37 C. The number of erythrocytes infected by A marginale appeared to increase 3.3-fold by day 11 and 4.5-fold by day 3, as determined by microscopic examination of Giemsa ...

Genetic diversity of Anaplasma marginale in Argentina

Veterinary Parasitology, 2009
Bovine anaplasmosis caused by Anaplasma marginale is a worldwide major constraint to cattle production. The A. marginale major surface protein 1 alpha (msp1alpha) gene contains a variable number of tandem repeats in the amino terminal region and has been used for the characterization of pathogen genetic diversity.
