Theileria parva: Expression of a sporozoite surface coat antigen
A monoclonal antibody specific for the Theileria parva sporozoite, which recognizes a determinant on the surface coat and blocks sporozoite infectivity, was used to investigate the presence of the determinant on other stages of the parasite lifecycle. Immunofluorescence techniques did not demonstrate this determinant on the kinete, schizont, merozoite,

DNA probes detect genomic diversity in Theileria parva stocks
Different stocks of Theileria parva were analysed for restriction fragment length polymorphisms by agarose gel electrophoresis, orthogonal-field-alternation gel electrophoresis (OFAGE) and Southern hybridization with DNA probes. Polymorphisms seen with DNA from purified piroplasms of different T.

Cycle of bovine lymphoblastoid cells parasitised by Theileria parva
The events were studied which occurred during different stages of the cell cycle of bovine lymphoblastoid cells infected with the parasite Theileria parva. The mean number of nuclei in macroschizonts was about 16 for cells in interphase and 30 for those in metaphase.

A pathogenic Theileria stock was isolated from control cattle during an East Coast Fever (ECF) field immunization trial at Kasoba near Karonga town in northern Malawi. A stabilate of this stock caused severe fevers and prolonged parasitosis in Theileria parva naive cattle, resulting in the death of 5 out of 12 cattle despite treatment.

Organisation and informational content of the Theileria parva genome
When compared with other Apicomplexan organisms, Theileria parva has an exceptionally small, 10-12 Mbp, genome. There are only 4 chromosomes, each in the Mbp range, and a complete physical map, based on SfiI linking data, is available for each one. A number of genes and cDNAs have been mapped to specific SfiI fragments.

Cell-mediated immune responses of cattle to Theileria parva
Theileria parva is a protozoan parasite that infects lymphocytes of cattle and African buffalo. As is the case with certain viruses, the parasite causes antigenic changes on the cell surface against which the host mounts cytotoxic T-cell. Precise definition of the cells participating in these response and their specificity has been facilitated by the ...

Theileria parasites invade and transform bovine leukocytes causing either East Coast fever (T. parva), or tropical theileriosis (T. annulata). Susceptible animals usually die within weeks of infection, but indigenous infected cattle show markedly reduced
