Anaplasma marginale is an etiologic agent of bovine anaplasmosis. This study aimed to molecularly detect and characterize A. marginale that is prevalent in Mongolian cattle populations. A highly specific and sensitive nested PCR (nPCR) method based on the Msp5 gene was developed to detect A. marginale (Msp5 nPCR). The method detected A. marginale from the(More)
Here we report on an epidemiological study regarding the molecular prevalence of different genotypes of Theileria orientalis present among domestic cattle and water buffalo populations bred in Thailand. A phylogenetic analysis based on the parasitic gene encoding a major piroplasm surface protein revealed the presence of 5 genotypes (Types 1, 3, 5, 7, and(More)
We conducted a molecular epidemiological study on Babesia bovis in Mongolia. Three hundred blood samples collected from cattle grazed in seven different districts were initially screened using a previously established diagnostic polymerase chain reaction (PCR) assay for the detection of B. bovis-specific DNA. Positive samples were then used to amplify and(More)
We developed a new nested PCR (nPCR) assay based on the Babesia bigemina apical membrane antigen-1 (AMA-1) gene sequence for parasite-specific detection. The primers were designed to amplify 738-bp and 211-bp fragments of the AMA-1 gene by primary and nested PCRs, respectively. The assay was proven to be specific for the B. bigemina, whereas the previously(More)
In the present study, we have surveyed the presence of a bovine Theileria protozoan, Theileria orientalis, in Mongolian cattle and engorging tick populations from selected provinces and districts in Mongolia. The percentages of infection in the cattle and ticks ranged from 8.8 to 66.6 and from 3.7 to 73.3, respectively, on a per district basis. The genetic(More)
A truncated fragment of the gene encoding the 200-kDa protein (P200) of Babesia bigemina was cloned into a plasmid vector, pGEX-4 T-1 and expressed in Escherichia coli as a glutathione-S-transferase fused protein. An indirect enzyme-linked immunosorbent assay (ELISA) using the rp200/CT detected specific antibodies in cattle experimentally infected with B.(More)
