“…Eight tick species of the genera Dermacentor, Hyalomma and Rhipicephalus are known to be vector ticks for T. equi parasite in Afro-Eurasian countries (Friedhoff and Soulé 1996). Hyalomma anatolicum ticks have been identified as natural potential vector for transmission of T. annulata parasite among Indian cattle population (Tiwari et al 2013;Haque et al 2010), but no molecular evidences are available on harbouring T. equi infective stage in H. anatolicum ticks infested on Indian equine field population.…”

A sizeable Indian equine population is considered to be pre-immune carrier of Theileria equi infection. In this study we confirmed the presence of T. equi specific DNA in Hyalomma anatolicum ticks which were infested on sero-positive horses. Fifty two Indigenous horses were randomly selected from endemic areas and their blood and tick samples were collected. Tick salivary glands and blood samples were processed for separation of DNA and serum, respectively. Serum samples were analyzed by EMA-2ELISA and nine horses were found positive for T. equi specific antibodies. Species-specific primers were designed from EMA-2 gene of T. equi, so as to amplify 398 bp fragment in PCR. The gene fragment was amplified in PCR on the DNA samples (from blood) from these nine sero-positive horses. Corresponding six tick's DNA samples collected from these nine seropositive animals were observed positive in PCR. Further, qPCR assay demonstrated presence of T. equi DNA in infected tick's salivary glands, which was also confirmed by microscopic examination of infected acinar. This study concluded that Hyalomma anatolicum ticks infested on T. equi seropositive horses have sporozoite developmental stage in their salivary glands, which is an evidence for transmitting potential of these tick among Indian horse population.

An epidemiological survey of Theileria annulata infection was undertaken in a cattle population in Rajshahi Division, Bangladesh. The local cattle breeds from the area (North Bengal Gray and Deshi) and crosses between the local breeds and Holstein cattle were predominantly screened. In total, 192 cattle serum samples were collected in two areas of Rajshahi Division, the Rajshahi District (n=147) and Natore District (n=45). The samples were screened with an enzyme-linked immunosorbent assay using T. annulata surface protein (TaSP) as the antigen. The seroprevalence was 80.0% (36/45) in Natore and 20.4% (30/147) in Rajshahi. A logistic regression analysis showed that the sampling location was significantly associated with seropositivity, whereas age, sex and breed were not. Although the logistic regression analysis did not show a linear dependence on age, we considered age-specific seroprevalence separately in the two districts. Seroprevalence did not differ significantly among age categories in the Natore District. In contrast, all the cattle <1 year old in the Rajshahi District were seronegative (11/11). Seroprevalence in the 1- and 2-year-old cattle was significantly lower in the Rajshahi District than in the Natore District. In the older age categories (3, 4 and >5 years), seroprevalence did not differ significantly between the Natore and Rajshahi Districts. These results suggest that the cattle in the Rajshahi District were sporadically exposed to T. annulata, whereas most cattle in the Natore District became infected during an early phase of life.
