Ticks and tick-borne diseases, including theileriosis, constitute a major constraint to livestock production. Two species, known as Theileria lestoquardi and Theileria ovis, are suspected to contribute to ovine theileriosis in Iran. However, the epidemiological aspects of ovine theileriosis are poorly understood in this country. In a survey, designed to identify Theileria species in sheep, 52 (...

In this study, the prevalence of piroplasms in sheep and goats was assessed with Giemsa-stained blood smear examination, PCR and nested PCR-restriction fragment length polymorphism (RFLP) to identify Babesia and Theileria species, respectively, in 338 small ruminants (172 sheep and 166 goats) from three sites in North-West Tunisia during the 2011 summer season. The overall infection prevalence ...

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...

A molecular study was undertaken to detect Theileria ovis, Theileria lestoquardi and Theileria annulata in sheep and tick vectors. Investigation was conducted from 2010 to 2011 in the south of Khorasan Razavi Province, Iran. A total of 150 blood samples were collected from 30 different sheep flocks. In addition, ixodid ticks were sampled from the same flocks. The stained blood smears were micro...

BACKGROUND Ovine babesiosis is the most important haemoparasitic tick-borne disease of small ruminants in Iran caused by Babesia ovis, B. motasi, and B. crassa. The aim of this study was to characterize the species of ovine Babesia species isolated from different geographical region of Iran. METHODS One hundred fifty four blood samples collected from animals, which demonstrated the pale mucou...

A total of 200 whole blood samples along with thin blood samples smears and 100 samples of ticks from 20 flocks of sheep from different localities of district Lahore with a history of tick infestation , relapse of fever and anemia were screened for the prevalence of Theileria species during spring and summer seasons in 2007. On microscopic examination 44/200 (22%) samples were positive for Thei...

background: babesia ovis and theileria ovis are among the important and main etiological agents causing ovine babesiosis and ovine theileriosis, causing severe economic losses among sheep and goats. the aim of the present study was to determine the prevalence and molecular diagnosis of b. ovis and t. ovis in lohi sheep at livestock experiment station bahadurnagar, okara, pakistan. methods: the ...

A molecular survey was performed for identification Theileria spp in sheep and ticks during from 2010-2011 in Fasa and Kazeroun areas, Fars province, Iran. A total of 100 sheep from different flocks were clinically examined and blood samples with ixodid ticks collected. The prepared blood smears from capillary vein of ear were stained with giemsa methods and examined by using light microscope. ...
