Molecular characterisation of the Theileria buffeli/orientalis group

International Journal for Parasitology, 2000
Benign bovine Theileria parasites known as either Theileria buffeli, Theileria orientalis or Theileria sergenti are classified on basis of their morphology, vector specificity, pathogenicity and 18S small subunit ribosomal RNA or major piroplasm protein (MPSP) sequences. Since most isolates have been characterized on only some of these criteria and the

Genetic diversity of Theileria orientalis from cattle in Turkey

Comparative Immunology, Microbiology and Infectious Diseases, 2019
Theileria orientalis is usually a benign parasite but some genotypes cause infection and economic losses to the cattle industry. This study was carried out to determine T. orientalis genotypes in cattle. T. orientalis positive 63 sample were analyzed by amplifying the MPSP gene region by PCR.

Evaluation of the natural vertical transmission of Theileria orientalis

Veterinary Parasitology, 2018
Bovine theileriosis, caused by Theileria orientalis, is endemic from East Asia to Oceania. Even though the disease is mainly transmitted by Haemaphysalis ticks, the T. orientalis parasite can also be transmitted vertically. To develop proper control measures, the frequency of each transmission route must be elucidated.

Genetic diversity and phylogeography of the global Theileria orientalis isolates inferred from MPSP gene sequences.

Parasitology international
BACKGROUND/OBJECTIVE Theileria orientalis is a non-transforming Theileria species infecting cattle and water buffaloes. Several outbreaks of oriental theileriosis accompanied by considerable economic loss were documented in Asia, Australia, and New ...

The first survey of Theileria orientalis infection in Mongolian cattle

Veterinary Parasitology, 2011
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.

Detection of Theileria orientalis in Iran by semi-nested PCR

Parasitology Research, 2011
In order to identify and differentiate Theileria orientalis in cattle which may be infected with Theileria annulata simultaneously, a semi-nested PCR was performed. Thus, 160 blood samples were collected from apparently healthy native cattle in Golestan province of northern Iran, during 2009 to 2011. The Tbs-S/Tbs-A primer set derived from the 18S rRNA

Phylogenetic, pathotyping and haplotype analysis of Theileria orientalis in crossbred cattle of northern Kerala, India.

Microbial Pathogenesis
Theileria orientalis, previously considered non-pathogenic, has recently been associated with clinical outbreaks of theileriosis in India, posing a significant threat to the dairy industry.

Detection and response to Haemaphysalis longicornis and Theileria orientalis Ikeda on a cow-calf farm in Tennessee (USA).

Medical and Veterinary Entomology
Bovine theileriosis is a vector-borne disease poised to become one of the most economically significant diseases of cattle in the United States. The hemoparasite Theileria orientalis Ikeda genotype causes bovine theileriosis (Piroplasmida: Theileriidae),

A novel colourimetric Loop-Mediated Isothermal Amplification (LAMP) assay for rapid field-level detection of Theileria orientalis.

Experimental parasitology
Theileria orientalis, the causative agent of oriental theileriosis is a globally distributed protozoan parasite affecting livestock. Rapid and accurate parasite detection is crucial for effective disease management and evaluating therapeutic ...
