Studies on Macroschizonts of Theileria parva

Research in Veterinary Science, 1961
SUMMARY A series of measurements was made of the schizonts of Theileria parva in the hope that these criteria might be used in the differential diagnosis of the theilerial species. Macroschizonts were found to have an average size of 4.8 μ, which was smaller than expected. They contained from 1 to 85 nuclei, with an average of 8.

Theileria parva: Significance of leukocytes for infecting cattle

Experimental Parasitology, 1978
Abstract Using an artificial feeding technique, infective particles of Theileria parva were harvested in bovine blood in capillary tubes from prefed female Rhipicephalus appendiculatus over a 2-hr period. Inoculations of this blood feed pool invariably resulted in the establishment of patent East Coast fever in autogeneic or syngeneic cattle, i.e.

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.

Aureomycin in Thieileria parva Infection

Nature, 1953
RECOGNITION of the selective action of quinine, atebrin and chloroquine on the haemotropic trophozoites of certain Plasmodium species, and that of plasmoquine on the exoerythrocytic trophozoites as well as on the gametocytes, forms the bases of modern chemotherapy of malaria in laboratory animals and in man.

The antitheilerial effects of Theileria parva parva reaction and recovery sera In vitro

International Journal for Parasitology, 1985
Abstract Peripheral blood leucocytes (PBL) of cattle were infected in vitro with the sporozoites of Theileria parva spp. The transformed cell lines were adapted to grow in sera from the PBL donors. The cattle were then infected with T. p. parva stabilate and either treated with parvaquone or the disease allowed to run its course. Sera harvested

Immunization of Cattle Against Theileria Parva

1977
Throughout its distribution in East and Central Africa, East Coast fever (ECF) is considered to be the most important of the tick-borne diseases which inhibit the development of the livestock industry. At present, the only method of controlling the disease is by close-interval application of acaricides to cattle, in dips or sprays, to kill the tick ...

Preliminary Experiments with Antigens of Theileria Parva (Theiler, 1904)

British Veterinary Journal, 1967
SUMMARY The agar gel precipitin test was used to study the antigens of Theileria parva. Fractions were prepared from pre- and post-infection blood and lymph glands from the same ox. Antisera were prepared on cattle by inoculating post-infection fractions prepared from blood and spleen in Freund’s adjuvant. At least four specific precipitin bands were

Bulk-freezing of Theileria parva stabilates for vaccine production

International Journal for Parasitology, 1996
The freezing and thawing characteristics of different volume samples of freezing medium and Theileria parva stabilates were studied in order to identify suitable conditions for freezing large volumes of stabilates for use in the preparation of vaccines.

Dose dependent responses of cattle to Theileria parva stabilate

International Journal for Parasitology, 1984
Abstract Dolan T. T. , Young A.S. , Losos G.J. , McMillan I. , Minder Ch.E. and Soulsby K. 1984. Dose dependent responses of Theileria parva stabilate. International Journal for Parasitology14: 89–95. A tick derived stabilate of Theileria parva (Maguga) was titrated in a large group of Boran (Bos indicus) cattle of the same age, sex and ...
