Theileria infection in bullfighting cattle in Thailand

Background and Aim: An apicomplexan protozoan parasite, namely, Theileria, primarily causes theileriosis in cattle worldwide. The virulence of the disease has been neglected because of it's low pathogenicity. However, the disease can have a substantial effect, depending on the virulence of the species, low host immunity, and coinfection. In Thailand, the molecular detection of Theileria infection in bullfighting cattle and its hematological alterations have not been reported. Thus, this study aimed to identify Theileria species in bullfighting cattle in Thailand. Materials and Methods: Blood samples were collected from bullfighting cattle presented at the Prince of Songkla University Animal Hospital and were determined on the basis of hematological evaluation and DNA extraction. Molecular detection using the 18s rRNA and merozoite surface antigen genes was conducted for Theileria spp. and Theileria orientalis, respectively. In addition, bidirectional sequencing of the positive samples was performed. Hematological alterations between Theileria infected and uninfected groups were statistically evaluated. Results: The levels of Theileria spp. and T. orientalis infection in bullfighting cattle were 44.62% (58/130) and 41.54% (54/130), respectively. Theileria orientalis, Theileria sinensis, and Theileria spp. infections were identified in bullfighting cattle samples. Hematological evaluation indicated that the red blood cell (RBC) level was significantly lower in Theileria-infected cattle. Conclusion: This study was the first to use molecular techniques in the identification of Theileria infection in bullfighting cattle in Thailand, with nearly one-half of the study population infected. Theileria infection in bullfighting cattle altered the RBC level, resulting in anemia. Therefore, tick control measures should be promoted.

“…The prevalence study revealed the dominance of T. orientalis over T. annulata. The higher presence of T. orientalis could be due to the possible role of the most abundant tick vector in India, Rhipicephalus sp in transmission (Patial et al 2021). Parasitemia of T. orientalis assessed through real time PCR in lactating cows of Odisha by RT PCR targeting MPSP gene from T. orientalis cloned into pUC57 estimated the parasitic load to be ranging from 6.9-16.8  10 3 /µl of blood (Sahoo et al 2020).…”

Background: Theileriosis is a haemoprotozoan illness that poses severe economic loss to dairy farmers due to its negative impact on mortality and productivity, especially in tropical and subtropical areas of the world. Methods: The present study was conducted for a period of one year (June 2020 to July 2021) during which 55 blood samples of cattle showing clinical signs suggestive of theileriosis were examined and quantified by using multiplex real time PCR for Theileria orientalis and Theileria annulata using Taq-Man probe. Result: Prevalence of theileriosis in three Theileria-endemic districts of Odisha due to Theileria annulata and Theileria orientalis were 26.11 per cent (11/42) and 57.14 per cent (24/42), respectively. Mixed infection were reported in 16.6 percent (7/42) cases. Parasite load for T. annulata in clinically affected cases ranged from 2.85 x 103 to 1.51 x 105 parasites per ml of blood while for T. orientalis, it ranged from 1.94 x 104 to 5.88 x 105 parasites per ml of blood. Ten cattle positive for T. orientalis were administered two doses of buparvaquone (Butalex) @2.5 mg/kg b.w. at an interval of 48 hours after which degree of parasitemia were quantified ten days post treatment. The parasitic load in blood ten days post treatment decreased significantly from 4.04 x 104 to 2.21 x 102 per ml of blood.

“…On the contrary, T. orientalis, T. sergenti and T. buffali are regarded as non-lymphoproliferative benign theileriosis [14], infecting a wide variety of hosts globally [15]. Although T. orientalis is known to be benign, disease outbreak has been reported from several countries [16][17][18][19][20].…”

Piroplasmosis, caused by Babesia spp. and Theileria spp., poses significant constraints for livestock production and upgradation in Bangladesh. Besides examining blood smears, few molecular reports are available from some selected areas in the country. Therefore, the actual scenario of piroplasmosis in Bangladesh is deficient. This study aimed to screen the piroplasms in different livestock species by molecular tools. A total of 276 blood samples were collected from cattle, gayals (Bos frontalis) and goats in five geographies of Bangladesh. Thereafter, screening was conducted through a polymerase chain reaction, and species were confirmed by sequencing. The prevalence of Babesia bigemina, B. bovis, B. naoakii, B. ovis, Theileria annulata and T. orientalis was 49.28%, 0.72%, 1.09%, 32.26%, 6.52% and 46.01%, respectively. The highest prevalence (79/109; 72.48%) of co-infections was observed with B. bigemina and T. orientalis. The phylogenetic analyses revealed that the sequences of B. bigemina, B. bovis, B. naoakii, B. ovis and T. annulata were included in one clade in the respective phylogram. In contrast, the sequences of T. orientalis were separated into two clades, corresponding to Type 5 and 7. To the best of our knowledge, this is the first molecular report on piroplasms in gayals and goats in Bangladesh.
