Multiplex PCR for rapid differential diagnosis of co-prevalent species of Theileria (Theileria annulata and Theileria orientalis) in cattle

Parasitology Research, 2023
Theileriosis is a tick-borne disease that causes enormous losses in the dairy industry. There are several species of Theileria that can infect bovines. Generally, more than one species are prevalent in any geographical area; thus, chances of co-infections are high.

Molecular epidemiology and genetic characterization of Theileria orientalis in cattle

Tropical Animal Health and Production, 2022
Theileria orientalis (T. orientalis) is a benign species of Theileria that is found all throughout the world, including Egypt. The purpose of this work was to determine the current status of T. orientalis infection in cattle, as well as to define T. orientalis genetic diversity using the major piroplasm surface protein (MPSP) genes.

Theileria orientalis outbreak in an organized cattle breeding farm

Veterinary Parasitology: Regional Studies and Reports, 2021
Theileriosis is an important tick borne disease of cattle caused by a haemoprotozoan of genus Theileria. Clinical bovine theileriosis is mainly caused by T. annulata or T. parva but the clinical disease due to T. orientalis is rare. T. orientalis mainly infect RBCs and causes "Oriental theileriosis" or Theileria-associated bovine anaemia in cattle and ...

Theileria orientalis : a review

New Zealand Veterinary Journal, 2015
Theileria orientalis (also known historically as T. sergenti and T. buffeli) is responsible for benign or non-transforming theileriosis, and exerts its major effect through erythrocyte destruction. The life cycle of T. orientalis is essentially similar to that of other Theileria species, except that the schizonts do not induce transformation and fatal ...

Investigation of Theileria spp. in Livestock in Northern Algeria and Identification of a Novel Haplotype of Theileria orientalis

Acta Parasitologica
Theileria species are tick-borne, intracellular apicomplexan protozoan parasites that pose a significant threat to livestock health and productivity. Theileria orientalis, the etiological agent of oriental theileriosis, is a benign Theileria species with worldwide distribution, including Algeria, where investigations on its prevalence and genetic ...

Theileria orientalis in cattle in Ethiopia

Research in Veterinary Science, 1983
The occurrence of Theileria orientalis in cattle in western Ethiopia was confirmed on morphological and serological grounds. The local vector remains unknown.

Theileria orientalis occurs in Central Africa

Research in Veterinary Science, 1986
An outbreak of bovine theileriosis in Burundi was investigated and the occurrence of Theileria orientalis in Central Africa was confirmed for the first time. Its identity was established on morphological and serological grounds. The parasite was associated with clinical signs and further complicates the disease picture of bovine theileriosis in Africa.

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.

Theileria orientalis Ikeda in host-seeking Haemaphysalis longicornis in Virginia, U.S.A.

Ticks and Tick-borne Diseases, 2020
The Asian longhorned tick, Haemaphysalis longicornis, has recently become established in the United States. In East Asia, Australia, and New Zealand, the native and previously introduced ranges, this tick is a vector of an important pathogen of cattle, Theileria orientalis. In 2017, the pathogenic Ikeda genotype of T.
