An economic evaluation of various control programmes against Theileria annulata infection was conducted on a sample of 49 Tunisian dairy farms where clinical cases of tropical theileriosis had been recorded during the summer. Indicators of morbidity and the prevalence of infection, as well as production and demographic indicators (recorded in the present survey ortaken from secondary sources), ...

Theileria parva-naïve Friesian (Bos taurus), Boran (Bos indicus) and Maasai Zebu steers (B. indicus) were infected with a T. parva sporozoite stabilate dose which had previously been shown to induce an estimated 50% mortality rate in Boran cattle. All the cattle developed patent infections with no significant differences in the length of the prepatent period to development of macroschizonts (P ...

background: the present study was carried out to investigate the accurate status of ovine theileria infection in sheep from ahvaz and surrounding region, a tropical area southwest iran. methods: a pcr-rflp method based on 18s ribosomal rna gene was designed which could detect and differentiate theileria and babesia spp. and also differentiate main theileria species in sheep at the same time. 11...

Theileriosis, caused by Theileria protozoa and infected by ticks, is a disease with high mortality rate. The most common species found in tropical and subtropical regions are T. annulata and T. parva. Theileriosis is often seen in cattle in the Eastern Anatolia Region, especially in the Van region. Clinical symptoms such as high fever, anaemia and haemoglobinuria are detected with this disease....

This study was performed to investigate the prevalence of theileriosis and to compare the prevalence of this disease in Korean native cattle reared under different environmental conditions, namely, in a grazing area and a non-grazing area by polymerase chain reaction. Three hundred and one Korean native cattle (276 cows and 25 bulls) that had not received prior treatment or been vaccinated to p...

an 8-day-old newborn female twin holstein calves with a history of weakness, anorexia, emaciation and convulsion were presented to tabriz university veterinary teaching hospital. on admission, the calves were febrile and recumbent. physical examination revealed many ticks from the external body surface of the animals, right and left prescapular lymphadenopathy, severe opisthotonos, nystagmus, p...

Aim The objective of this study was to examine the carrier status of theileriosis among apparently healthy cross-bred jersey cattle population of Odisha using conventional blood smear examination and polymerase chain reaction (PCR). Materials and Methods A total of 34 apparently healthy cross-bred Jersey lactating cows were considered in this study. Blood samples were subjected to microscopic...

background: in this study, the pilot production of aerobic bioreactor tropical theileriosis vaccine was optimized with the aim of immunological assays for further mass production. methods: we have shown earlier the delayed type hypersensitivity (dth) assay could be used for evaluating the immunity and memory cells against specific theileria antigen in vaccinated animals. in addition, tnf-α is t...

Received: Revised: Accepted: Published online: June 18, 2016 October 13, 2016 October 14, 2016 November 17, 2016 The word-wildly spread Theileria, is an economical important parasite to sheep and goats production. However, a little is known about whether goats in Hubei province are exposed to Theileriosis. Therefore, a survey was conducted to investigate the prevalence of Theileria infection in...
