Investigation of lectin activity in Theileria annulata piroplasms

Acta Veterinaria Hungarica, 2005
Adhesion to target cells is an essential step in the pathogenesis of many protozoal infections. Some protozoa have been reported to have a lectin activity involved in their attachment to the cell surface. The ligand-receptor interaction involved in Theileria annulata infection is unclear at present, in spite of the fact that some aspects of the process

In vivo evidence for the resistance of Theileria annulata to buparvaquone

Veterinary Parasitology, 2010
The present study describes an outbreak of tropical theileriosis cases refractory to buparvaquone treatment, which occurred in a small-size dairy farm in Tunisia. Out of seven treated cows, four died in spite of repeated buparvaquone injections (2.5 and 5 mg kg(-1)) and the monitoring of the affected cows showed no improvement of the course of the ...

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.

Common and stage-specific antigens of Theileria annulata

Veterinary Immunology and Immunopathology, 1992
Western blot analysis of Theileria annulata antigens was carried out using sera collected from cattle which had been immunised and challenged with either T. annulata sporozoites or schizont-infected cells. Three antigens between 71 and 73 kDa proved to be common to the three stages of parasite studied: sporozoites, schizonts and piroplasms.

Naturally occurring infections of cattle with Theileria lestoquardi and sheep with Theileria annulata in the Sudan

Veterinary Parasitology, 2013
Theileria annulata is endemic in northern Sudan, hindering all efforts at upgrading cattle for milk production. T. lestoquardi clinical cases occur throughout the year and causes annual outbreaks that result in substantial losses in sheep. In the northern Sudan both cattle and small ruminants are frequently raised together and/or share common grazing ...

First molecular evidence of the transplacental transmission of Theileria annulata

Tropical Animal Health and Production, 2015
Bovine tropical theileriosis (BTT) is a serious hindrance in the cattle upgradation programme using the exotic germplasm. There is a wide range of variations in the pathobiology alongside clinical symptoms of the animals suffering from BTT. The present paper communicates the first report about the transplacental transmission of T.

Growth of Theileria annulata and T. parva in tissue culture

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1958
1. 1) Theileria annulata was grown in tissue culture for over 59 days from implants of infected spleen, lymph node or liver. Multiplication of the parasites occurred and the cultures were infective for cattle when tested after 17 and 42 days. This confirms earlier work by TsUR (Tchernomoretz), 1945. 2. 2) T.

Developmental expression of a Theileria annulata merozoite surface antigen

Molecular and Biochemical Parasitology, 1990
Culture of a lymphoblastoid cell line infected with the macroschizont stage of the protozoan parasite Theileria annulata at 41 degrees C induces differentiation to the next stage, the merozoite. We have demonstrated that this development results in the loss of monoclonal antibody epitopes associated with the macroschizont stage, and the appearance of ...

Elimination of the gametocytes of Theileria annulata of cattle by primaquin phosphate

Veterinary Parasitology, 1987
Calves were experimentally infected with Theileria annulata and five drugs were administered in an attempt to exterminate the gametocytes of the parasite. The results of the experiment proved that primaquin phosphate is an effective parasiticide. The gametocytes from 30 calves treated with primaquin phosphate were exterminated completely.
