Comparative evaluation of antibody positive titer by ELISA and IFA in Theileria annulata vaccinated cattle in Iran.

Complement-fixing antibodies in cattle experimentally infected with Theileria annulata or vaccinated with tissue cultures

Theileria annulata: cross-reactions between a cell culture schizont antigen and antigens of East African species in the indirect fluorescent antibody test.

BURRIDGE, M. J., BROWN, C. G. D., AND KIMBER, C. D. 1974. Theileria anndata: Cross-reactions between a Cell Culture Schizont Antigen and Antigens of .East African Species in the Indirect Fluorescent Antibody Test. Experimental Parasitology 35, 374380. A schizont antigen for the indirect fluorescent antibody test was prepared from an in &TO culture suspension of lymphoid cells infected with Thei...

In silico analysis of Ta9 gene polymorphism in an Iranian Theileria annulata schizont-infected cell line S15 vaccine strain and native isolates

Bovine theileriosis is a tick-borne disease caused by obligate intracellular parasites related to the genus Theileria. Cellular immune responses protect cattle against pathogens through the activation of immune cells. Nowadays, live, attenuated vaccine of Theileria annulata (T. annulata) is being produced in Iran and is recommended for active cattle immunization. Detection of the immunogenic  a...

Detection of Native Carrier Cattle Infected with Theileria annulata by Semi-Nested PCR and Smear Method in Golestan Province of Iran

Theileria annulata, as a pathogenic agent of tropical theileriosis, gives rise annually to serious economic losses in cattle industry of Iran. The carrier cattle, harbouring the latent forms of Theileria annulata, play a major role in infecting tick vectors and in disseminating the infection. The aim of this study was determining the carrier cattle, infected with Theileria annulata in Golestan ...

Single dilution ELISAs using soluble piroplasm, cellular schizont and soluble schizont antigens for the detection of antibodies against Theileria annulata.

Single dilution ELISAs were standardised for the determination of antibody titres against Theileria annulata using three antigens namely soluble piroplasm, cellular schizont or soluble schizont antigens. Antibody titres of 20 cattle serum samples of known identity were determined by multi-dilution ELISA using the three antigens. The ratio of the optical density (OD) of known positive and known ...
