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...

BACKGROUND We used the PCR technique based on the abovementioned primer pair and sequencing to demonstrate the Theileria infection in the sheep samples collected from Sultanate of Oman. METHODS According to the frame work of "integrated control of ticks and tick borne diseases in globalized world managed by EU-ICTTD-3 project, the samples from blood, liver, spleen, lymph node and lung were se...

This study was aimed to determine the infection rate and vectors of Theileria lestoquardi in goats from West Azerbaijan province, Iran. A total of 400 blood samples were collected from 40 randomly selected flocks in the study area from June to September, 2014. Out of 400 blood samples examined using microscopic examination, a number of 14 goats (3.50%) were positive for Theileria</...

As part of an international effort to develop vaccines for Theileria lestoquardi, we undertook a limited screen to test T. lestoquardi orthologues of antigens recognised by CD8+ T lymphocyte responses against T. annulata and T. parva in cattle. Five MHC defined sheep were immunized by live T. lestoquardi infection and their CD8+ T lymphocyte responses determined. Thirteen T. lestoquardi ortholo...

Theileria species are common in tropical and subtropical regions and cause great economical losses inruminants. Two species, T. lestoquardi and T. ovis, are suspected to cause ovine theileriosis in Iran. Theepidemiological aspects of ovine theileriosis in Iran are poorly understood and further investigations bysensitive and precise techniques are required. In a previous study, a sensitive and s...

Little is known about tick-borne diseases in Saudi Arabia, particularly regarding the prevalence of theileriosis in small ruminants. This survey studied the potential vectors of malignant theileriosis in Saudi Arabian sheep. Blood, lymph node and tick samples were collected from animals being treated or necropsied at the Veterinary Diagnostic Laboratory in Jeddah, Makkah (western region), and B...

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 (...

Hyaloma spp. has been described as the most abundant species that transmitted ovine piroplasms in Fars province. The traditional methods of diagnosis infected ticks vectors are based on morphological characteristics that have some problems. The best methods for detection and characterization of the protozoan parasites in ticks are the molecular biological methods. The aim of this study was to s...
