Theileria orientalis

Theileria orientalis (Apicomplexa: Piroplasmida) has caused clinical disease in cattle of Eastern Asia for many years and its recent rapid spread throughout Australian and New Zealand herds has caused substantial economic losses to production through cattle deaths, late term abortion and morbidity. Disease outbreaks have been linked to the detection of a pathogenic genotype of T. orientalis, genotype Ikeda, which is also responsible for disease outbreaks in Asia. Here, we sequenced and compared the draft genomes of one pathogenic (Ikeda) and two apathogenic (Chitose, Buffeli) isolates of T.

The present investigation was done for one year to record the prevalence of haemoparasite species in crossbred and domestic cattle along the four Indo-Bhutan border districts of Assam. Microscopic examination of blood smears from 533 cattle resulted in overall prevalence of 67.35% and detection of three species, viz.

Theileriosis is a tick borne haemoprotozoan disease caused by Theileria spp, Theileria annulata and Theileria orientalis most commonly. The disease has gained economic importance as it causes huge losses to farmers in the form of decrease milk production and expensive treatment of the disease.

The prevalence of bovine babesiosis and theileriosis in northern, middle and southern regions of Kerala was studied. A total of 246 apparently normal/healthy crossbred adult cattle blood smears were screened by microscopy after Giemsa’s staining.

The study revealed, benign theileriosis, which is caused by Theileria orientalis conformed by using the PCR/ Blood smear/ Lymph node aspiration smear examination. The incidence of theileriosis was 24.21% to the total cases recorded in the veterinary hospital. Based on the clinical suspicion the incidence rate is 90.91%. The incidence rates of theileriosis in female animals (85%) were higher than male (15%) animals. Age 3-4 years (34%) and 5-6 years (20%) higher the Theileria incidence rate than the younger animals (9%).

The study was carried out to assess the status of theileriosis in cattle and buffaloes using biochemical levels of serum calcium, phosphorous and adenosine deaminase. Cattle and buffaloes naturally infected with Theileria annulata and Theileria orientalis were examined through biochemical analysis and the estimates were correlated to determine the severity of infection, immunological responses and the extent of tissue damage. A total of 50 cattle and 50 buffaloes were sampled for the study which included both infected and noninfected group.
