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

Trypanosoma (Megatrypanum) theileri is a cosmopolitan, usually non-pathogenic, trypanosome of cattle transmitted by blood-sucking arthropods, mainly tabanid flies. Several T. theileri strains isolated from domestic and wild ruminants via co-culturing with mammalian feeder cells or blood cells have...

Abstract

Mongolia is an agriculturally rich country with large livestock populations that contribute significantly to its national economy. However, the export market for live animals and livestock products is often constrained for various reasons including infectious diseases. Babesia bovis and B. bigemina...

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

Oriental theileriosis caused by Theileria orientalis is an economically significant disease in cattle farming. The lack of laboratory animal models and in vitro culture systems is a major obstacle in the drive to better understand the biology of this parasite. Notably, research on the sporozoite...

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

We screened cattle and goats from the districts of Chama, Monze and Mumbwa in Zambia for animal African trypanosomes, Babesia bigemina and Theileria parva using PCRs; 38.1% of the samples tested positive for at least one of the parasite species. The most common parasite was Trypanosoma vivax...
