BACKGROUND Bovine theileriosis results from infection with obligate intracellular protozoa of the genus Theileria. The phylogenetic relationships between two isolates of Theileria annulata, and 36 Theileria spp., as well as 6 outgroup including Babesia spp. and coccidian protozoa were analyzed using the 18S rRNA gene sequence. METHODS The target DNA segment was amplified by PCR. The PCR produ...

Abstract Background Epidemiological surveys in Oman have revealed a high prevalence of the co-occurrence pathogenic Theileria lestoquardi and non-pathogenic ovis among sheep Barka region, Oman. Our most recent data illustrated an interaction reduced mortality risk animals co-infected with T. , suggesting that latter confers protection against pathogenicity . The present study extends above find...

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. ...

Theileria annulata, which is part of the Theileria sergenti/Theileria buffeli/Theileria orientalis group, preferentially infects cattle and results in high mortality and morbidity in the Mediterranean, Middle East, and Central Asia. The polypeptide Tams1 is an immunodominant major merozoite piroplasm surface antigen of T. annulata that could be used as a marker for epidemiological studies and p...

Malignant Ovine Theileriosis (MOT) is a tick borne disease of sheep and goats, caused by Theileria lestoquardi and is considered a major constraint for sheep production in many areas of the world. It has been reported to infect lymphocytes in vivo and in vitro and the schizonts differentiate into macro-schizonts and micro-schizonts. To date, little is known about the mechanisms involved in the ...

background: theileriosis is a blood protozoan disease with high mortality in cattle in tropical and subtropical regions of the world. several studies were conducted to identify theileria species in infected cattles and vector ticks by microscopic examination. however, microscopic technique has lower sensitivity compared to molecular method.                  objectives: this study was carried ou...

Malignant Ovine Theileriosis (MOT), caused by Theileria lestoquardi, is a major constraint for sheep production in many areas of the world including Sudan. Export sheep and sheep products are a major component of Sudan national economy and foreign income. Despite the importance of the disease, there is a considerable lack of detailed information regarding the postmortem and histological manifes...

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...
