Abstract

A PCR-based survey of hemoprotozoa parasites detected Babesia bigemina, Theileria orientalis and Trypanosoma theileri among cattle and water buffalo in Vietnam, and a new Babesia sp. closely related to Babesia ovata was detected in cattle only. In addition, Theileria annulata and Trypanosoma evansi ...

Abstract

Bovine babesiosis is a serious threat to the cattle industry. We prepared blood DNA samples from 13 cattle with clinical babesiosis from the Badulla (n=8), Jaffna (n=3), and Kilinochchi (n=2) districts in Sri Lanka. These DNA samples tested positive in PCR assays specific for Babesia bovis (n=9), ...

Abstract

Species of Theileria are tick-borne hemoprotozoan parasites of ruminants that can cause severe clinical disease. In this study, blood samples were obtained from 91 wild sika deer in various districts in Hokkaido, Japan. Samples were tested using a PCR assay designed to amplify a full-length major...

Abstract

East Coast fever, babesiosis, and anaplasmosis are the major tick-borne diseases affecting cattle productivity in Uganda. The emergence of acaricide-resistant ticks is suspected to have caused a rise in hemoparasites. This study sought to detect and characterize hemoparasites among farms in...

Abstract

Background: Bovine babesiosis, mainly caused by Babesia bovis and B. bigemina, is a huge threat to the livestock industry. In Indonesia, the current distribution of the disease is unknown due to a lack of scientific study. Methods: In the present study, 487 blood samples were collected from cattle...

Abstract

Trypanosoma theileri is a hemoprotozoan parasite that infects various ruminant species. We investigated the epidemiology of this parasite among cattle and water buffalo populations bred in Sri Lanka, using a diagnostic PCR assay based on the cathepsin L-like protein (CATL) gene. Blood DNA samples...

Abstract

Theileria orientalis often causes clinical anemia in cattle. In the present study, the red blood cell (RBC) indices of cattle, as measured in T. orientalis-endemic regions of Hokkaido, Japan, were analyzed. In comparison with the non-infected animals, the mean values for RBC counts, hematocrit, and ...

Abstract

The genes that encode merozoite surface antigens (MSAs) in Babesia bovis are genetically diverse. In this study, we analyzed the genetic diversity of B. bovis MSA-1, MSA-2b, and MSA-2c genes in Vietnamese cattle and water buffaloes. Blood DNA samples from 258 cattle and 49 water buffaloes reared in ...
