Molecular study on infection rates of Anaplasma ovis and Anaplasma marginale in sheep and cattle in West-Azerbaijan province, Iran
This study was carried out to determine the presence and frequency of Anaplasma ovis and Anaplasma marginale in sheep and dairy cattle in West-Azerbaijan province, Iran. A total number of 200 blood samples were randomly collected via the jugular vein from apparently healthy cattle (100) and sheep (100). The extracted DNA from blood cells was screened using genus-specific (Anaplasma...
متن کاملCyclic rickettsemia during persistent Anaplasma marginale infection of cattle.
Submicroscopic levels of Anaplasma marginale rickettsemia in persistently infected cattle were determined by using nucleic acid hybridization. Within individuals, the rickettsemia levels steadily increased from less than 10(4) infected erythrocytes per ml to a peak of more than 10(6) infected erythrocytes per ml and then rapidly declined. This logarithmic variation parallels the variation of th...
متن کاملHigh Genetic Diversity of Anaplasma marginale Detected from Philippine Cattle
A total of 658 cattle in 6 provinces in the Philippines were screened for Anaplasma marginale infection by using a diagnostic heat-shock operon (groEL) gene-PCR assay. The screening-positive samples were further tested using the major surface antigen protein 1a (Msp1a) gene-PCR assay. Screening PCR results showed 130 cattle (19.8%) were positive for the A. marginale infection. Subsequent amplif...
متن کاملDiagnostic accuracy of methods for detecting Anaplasma marginale infection in lactating dairy cattle of Puerto Rico.
Bovine anaplasmosis (BA) is a hemoparasitic disease of great importance in cattle within the tropical and subtropical regions of the world. Control programs for BA require accurate diagnostic assays but validation can be challenging because the true disease status of all animals is frequently not known with certainty. The objective of this study was to estimate the accuracy of assays for detect...
