“…As reported by Sangwan et al (1989), the prevalence of Theileria infection was not significantly different between female and male ticks, whereas Büscher and Tangus (1986) and Sayin et al (2003) emphasized on the role of the tick sex in Theileria prevalence stating a higher intensity of Theileria infection in female ticks than in males.…”

The presence of potential vectors, ticks, and susceptible hosts of bovine malignant theileriosis in all parts of Iran pose a real threat to food animal industry. The present study was conducted to determine the infection rate of ticks collected from naturally occurring bovine theileriosis in West and North-West Iran. Two hundred and thirty seven cattle suspected of suffering from theileriosis were investigated for the presence of Theileria annulata in the blood smears and any tick species on their body. In this study, 402 ticks were obtained from 99 cattle. The examination of 402 ticks by polymerase chain reaction (PCR) using primers derived from the gene encoding heat shock protein70 (Hsp70) revealed that 39.9% of Hyalomma anatolicum anatolicum, 3.5% of H. asiaticum asiaticum, and 18.2% H. anatolicum excavatum, were infected with T. annulata. The results suggest that H. a. anatolicum may play a major role in transmission of T. annulata infection in Iran. Finally, digestion of the PCR products of T. annulata with two different restriction enzymes produced only a single pattern.

“…The mean intensity of Theileria infection in female and male ticks of H. a. anatolicum species was different with female ticks having higher intensity than the male. The role of the sex of the tick in Theileria transmission has previously been emphasized and it has been reported that both the prevalence and the intensity of Theileria infection were significantly higher in female ticks than in male ticks (Walker et al 1983;Buscher and Tangus 1986;Sangwan et al 1989;Sayin et al 2003;Aktas et al 2004). The female ticks play a more important role in the transmission of Theileria infection as they had more abundance of type III acini than male ticks and Theileria parasites were only detected in type III acini (Irvin et al 1981;Pipano et al 1982;Young et al 1983).…”

The study was conducted to assess the prevalence of Theileria infection in tick vectors collected from healthy animals to record the natural infection level of theilerial parasite in the field condition. A total of 156 male and 110 semi-engorged female of Hyalomma anatolicum anatolicum were collected from cattle and buffaloes of two different agro climatic zones of Punjab, dissected and their salivary glands were stained with Methyl Green Pyronin (MGP) stain. The prevalence, intensity and abundance of Theileria annulata infection were higher in female ticks (15.45%, 5.08 and 32.88, respectively) than male ticks (8.97%, 1.69 and 18.86, respectively). The ticks collected from cattle had a higher prevalence, abundance and intensity (15.15%, 5.38 and 35.53, respectively) of T. annulata infection than the ticks collected from buffaloes (9.58%, 1.74 and 18.13, respectively). Hot and dry climate favored the development of T. annulata sporozoites in H. a. anatolicum ticks as the prevalence, abundance and intensity of T. annulata infection were higher in ticks collected from Western semi arid zone of Punjab as compared to those collected from the central plain zone with hot and humid climate.

Tropical theileriosis is a progressive bovine lymphoproliferative disease caused by the intracellular protozoan parasite Theileria annulata. In this study 138 blood samples and 289 ticks were collected and examined from cattle that belonged to 10 randomly selected flocks. The Tbs-S/Tbs-A primer set was used for PCR amplification of Theileria spp. and the Ta-S/Tbs-A specific primer set was used in semi-nested PCR technique for detection of T. annulata. Blood smears of each case were examined by Giemsa staining method. The semi-nested PCR accurately revealed 22 (15.94 %) positive samples; whereas Giemsa staining method could detect 15 (10.86 %) out of 138 blood samples. The examination of 289 ticks by semi-nested PCR revealed that, 32.86 % of Hyalomma anatulicum anatulicum, 26.47 % of Hyalomma anatulicum excavatum and 22.42 % of Hyalomma asiaticum asiaticum, were infected with T. annulata. The results suggest that H. anatulicum anatolicum may play a major role in transmission of T. annulata infection in Iran. The results indicated that the Giemsa staining method, having low sensitivity, while the semi-nested PCR technique can be used as a gold standard method for this purpose.
