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

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.

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 ...

Lyophilisation and resuscitation of sporozoites of Theileria parva: preliminary experiments

Vaccine, 2003
Lyophilisation of Theileria parva sporozoite stabilates used for immunisation of cattle against East Coast fever would greatly improve vaccine storage and delivery. We report three attempts to lyophilise and resuscitate the sporozoites of T. parva. Sporozoites survived lyophilisation and were effective for immunisation.

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.

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

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.

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.

Artificial infection of the tick Rhipicephalus appendiculatus with Theileria parva

Research in Veterinary Science, 1979
Methods for infecting Rhipicephalus appendiculatus ticks with Theileria parva by injection and by artificial feeding were confirmed and compared. The injection method proved simpler and at best as effective and suggested improvements are described.

Heterotransplantation of Theileria parva-infected cells to athymic mice

Nature, 1975
CONGENITALLY athymic (nude) mice have been used for the heterotransplantation and maintenance of human tumours1–6. In many cases aplasia of the thymus is sufficient to allow tumour growth and other immunosuppressive treatments are apparently unnecessary.
