Molecular detection of Theileria annulata, Theileria mutans and Theileria velifera but no evidence of Theileria parva infected or vaccinated cattle in Nigeria despite extensive transboundary migrations

Veterinary Parasitology: Regional Studies and Reports, 2023
The extensive livestock management system predominant in Nigeria necessitates active disease surveillance for the early detection and prompt control of transboundary animal diseases. Theileriae are obligate intracellular protozoa which infect both wild and domestic bovidae throughout much of the world causing East Coast Fever (Theileria parva ...

Theileria secretes proteins to subvert its host leukocyte

Biology of the Cell, 2020
Theileria parasites are classified in the phylum Apicomplexa that includes several genera of medical and veterinary importance such as Plasmodium, Babesia, Toxoplasma and Cryptosporidium.

Theileria ovis discovered in China

Experimental Parasitology, 2011
A polymerase chain reaction (PCR) using 989/990 primers was conducted to identify a newly isolated Theileria sp. in Xinjiang Province of China. The target DNA fragments of the complete 18S rRNA gene were cloned and sequenced. The phylogenetic relationship of newly isolated Theileria spp. was inferred based on the 18S rRNA gene.

Chemotherapy of Theileria parva infection

Nature, 1976
EAST coast fever (ECF), the most important tick-borne disease of cattle in eastern and central Africa, is caused by the protozoan parasite Theileria parva. No successful therapy is available and mortality can reach 96% (ref. 1), although large doses of tetracyclines have some prophylactic effect2.

Theileria parya: Kinetics of replication

Experimental Parasitology, 1969
Abstract The kinetics of replication of Theileria parva (Muguga) in the bovine host were studied using infections produced by 10 1 , 10 2 , and 10 3 ticks. It was found that the growth of the organism was exponential from at least days 11–21 and probably from the start of growth in the bovine host.

Transient transfection of Theileria annulata

Molecular and Biochemical Parasitology, 2001
We have developed a method to transiently transfect infective, uninucleate, Theileria annulata sporozoites. Transfection vectors have been constructed using a number of T. annulata 5' gene flanking sequences linked to the enhanced green fluorescence protein (eGFP) reporter gene.

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 ...

Isolation of a Bovine Theileria

American Journal of Veterinary Research, 1975
SUMMARY Dual infections of Anaplasma marginale and a Theileria, resembling Theileria mutans, occurred in splenectomized calves inoculated with pooled blood samples from eastern Texas cattle. Theileria was obtained in pure form by treating dually infected cattle with gloxazone and imidocarb which selectively eliminated Anaplasma.

Infection of bovine monocyte/macrophage populations with Theileria annulata and Theileria parva

Veterinary Immunology and Immunopathology, 1989
Infection and transformation of cells of the bovine immune system by Theileria annulata and T. parva were compared. Preliminary experiments with mammary gland macrophages indicated that they were permissive to infection by T. annulata but only to a limited extent by T. parva.

Chemoprophylaxis of Theileria annulata and Theileria parva infections of calves with buparvaquone

Veterinary Parasitology, 1998
A clinical trial testing the prophylactic effect of a 5 mg kg-1 dose of buparvaquone on either Theileria annulata or Theileria parva experimental infections of calves demonstrated its efficacy for periods of at least seven days. The drug given 1 h or seven days before 50% lethal T.
