Theileria annulata, a protozoan parasite of cattle and domestic buffaloes, is transmitted by ticks of the genus Hyalomma, and causes a disease named Mediterranean or tropical theileriosis. In this research 50 cattle naturally infected with Theileria annulata were treated with the extract of the plant Peganum harmala. The treatment was continued for 5 days, the dose of the extract being 5 mg/kg ...

Cattle were infected with three isolates of Theileria parva and treated with halofuginone lactate during acute clinical disease. The health, weight gain and carrier state of the cattle were monitored for 15 months. Limited treatment rapidly reduced fever and parasitosis but parasite recrudescences occurred and 12 out of 21 treated cattle died. Persistent carrier states were identified with two ...

more than 185 species, strains and unclassified theileria parasites are categorized in the entrez taxonomy. the accurate diagnosis and proper identification of the causative agents are important for understanding the epidemiology, prevention and appropriate treatment. this study aims to discuss the importance of two genes of theileria annulata 18s ribosomal rna (18s rrna) and theileria annulata...

background: bovine theileriosis results from infection with obligate intracellular protozoa of the genus theileria . the phylogenetic relationships between two isolates of theileria annulata , and 36 theile­ria spp . , as well as 6 outgroup including babesia spp . and coccidian protozoa were analyzed using the 18s rrna gene sequence. methods: the target dna segment was amplified by pcr. the pcr...

For the evaluation of the epidemiology of Theileria equi and Babesia caballi in a herd of 510 horses in SW Mongolia, several mathematical models of the transmission dynamics were constructed. Because the field data contain information on the presence of the parasite (determined by PCR) and the presence of antibodies (determined by IFAT), the models cater for maternal protection with antibodies,...

Some characteristics of a strain of Theileria mutans (Theiler, 1906) isolated from cattle in the County of Kent, England and maintained in splenectomized calves. International Journal for Parasitology, 2: 265-271. A strain of T. mutans was isolated from British cattle and maintained by blood inoculation in splenectomized calves. The strain ...

Intracellular schizonts of the apicomplexans Theileria annulata and Theileria parva immortalize bovine leucocytes thereby causing fatal immunoproliferative diseases. Buparvaquone, a hydroxynaphthoquinone related to parvaquone, is the only drug available against Theileria. The drug is only effective at the onset of infection and emerging resistance underlines the need for identifying alternative...

The Theileria parva carrier-state in cattle on commercial farms on Zimbabwe was investigated using parasitological and serological methods. The proportion of cattle showing Theileria piroplasms on two farms, which had recent histories of disease outbreaks, were 64% (n = 106, total of heifers and weaned calves examined) and 71.5% (n = 60) while the proportion of T. parva antibodies for the same ...

This study was carried out to determine the presence and distribution of tick-borne haemoprotozoan parasites (Theileria and Babesia) in apparently healthy cattle in the East Black Sea Region of Turkey. A total of 389 blood samples were collected from the animals of various ages in six provinces in the region. Prevalence of infection was determined by reverse line blot (RLB) assay. The hypervari...
