“…The results showed that H. a. anatolicum is the major tick species of cattle in the West and North-West Iran (P<0.05). The prevalence of T. annulata infection was higher in H. a. anatolicum, than in H. a. excavatum and H. a. asiaticum as reported by Sangwan et al (1989) and Aktas et al (2004) (Bhattacharyulu et al 1975, Samish andPipano 1983). In general, ticks found in the present study were the same as described previously in the region Telmadarraiy et al (2004).…”

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.

“…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 prevalence rate of Theileria infection was higher in female ticks than in males as has been earlier reported by several workers (Walker et al 1983;Buscher and Tangus 1986;Sangwan et al 1989;Haque et al 2010). The female ticks play a more important role in the transmission of Theileria infection as they have more abundance of type III acini than male ticks and Theileria parasites were only detected in type III acini (Irvin et al 1981).…”

The prevalence of Theileria infection in tick vector Hyalomma anatolicum anatolicum collected from healthy animals of Ludhiana district, Punjab was recorded to assess the natural infection level of theilerial parasite in the field condition. A total of 60 semi-engorged H. a. anatolicum were collected from cattle and their salivary glands were dissected out. One half of the salivary gland was stained with methyl green pyronin (MGP) and the other half was utilized for DNA isolation for molecular detection of Theileria infection. A PCR and nested PCR assays were standardized for the detection of T. annulata infection in salivary gland of H. a. anatolicum. The prevalence of T. annulata infection was recorded as 8.3, 20.0 and 60.0 % by MGP staining, primary PCR and nested PCR, respectively. Further, the prevalence was higher in female ticks (8.8 %) than male ticks (6.6 %). The results demonstrated that both primary and nested PCR assays are a valuable technique for detection of T. annulata infection in vector tick under field conditions.

“…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).…”

Prevalence of Theileria annulata infection in Hyalomma anatolicum anatolicum in Punjab state, India

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.
