    First report on the occurrence of Microphallus indicus in the Sartoriana spinigera freshwater crab in Bangladesh
    (Паразитология, 2024-09) Wasef, Al; Adhikary, Anup Kumar; Abdullah, S. M.; Mohanta, Uday Kumar
    Sartoriana spinigera is an edible freshwater crab species that plays an important role as an intermediate host of Microphallus indicus and Paragonimus westermani. P. westermani, the lung fluke, has been reported from northeastern India bordering Bangladesh and other parts of India. Nonetheless the existence of P. westermani in Bangladesh is yet to investigate. Therefore, the objective of the study was to estimate the prevalence of lung flukes in Bangladesh. During the survey, the metacercariae of food-borne trematodes were investigated from a total of 261 fresh-water crabs collected from different locations in Bangladesh. Only the metacercariae of M. indicus were recovered. The overall prevalence of M. indicus metacercariae was 26% with intensity of 1–63 per crab. The highest prevalence was recorded from Naogaon district (83.33%), followed by Sirajgonj (57.5%), Rajshahi (40%), Brahmanbaria (16%), Narsingdi (15%), Faridpur (10%), and Sunamgonj (7%). None of the crabs from Rangpur, Thakurgoan, Jashore, Meherpur, Magura, Barguna, Sylhet, Kishorgonj, Cox’sBazar, and Bandarban were infected. Among the water bodies, the highest number of infected crabs was found in the rivers (56%) followed by haor, canal, and ditches (5%). To the best of our knowledge, this study reports M. indicus for the first time from Bangladesh.

    Molecular Detection of Theileria ovis, Anaplasma ovis, and Rickettsia spp. in Rhipicephalus turanicus and Hyalomma anatolicum Collected from Sheep in Southern Xinjiang, China
    (Pathogens, 2024-08) L, Yongchang; Li, Jianlong; Xieripu, Gulaimubaier; Rizk, Mohamed Abdo; Macalanda, Adrian Miki C.; Gan, Lu; Ren, Jichao; Mohanta, Uday Kumar; El-Sayed, Shimaa Abd El-Salam; Chahan, Bayin; Xuan, Xuenan; Guo, Qingyong
    The Xinjiang Uygur Autonomous Region (Xinjiang) borders eight countries and has a complex geographic environment. There are almost 45.696 million herded sheep in Xinjiang, which occupies 13.80% of China's sheep farming industry. However, there is a scarcity of reports investigating the role of sheep or ticks in Xinjiang in transmitting tick-borne diseases (TBDs). A total of 894 ticks (298 tick pools) were collected from sheep in southern Xinjiang. Out of the 298 tick pools investigated in this study, Rhipicephalus turanicus (Rh. turanicus) and Hyalomma anatolicum (H. anatolicum) were identified through morphological and molecular sequencing. In the southern part of Xinjiang, 142 (47.65%), 86 (28.86%), and 60 (20.13%) tick pools were positive for Rickettsia spp., Theileria spp., and Anaplasma spp., respectively. Interestingly, the infection rate of Rickettsia spp. (73%, 35.10%, and 28.56-41.64%) was higher in Rh. turanicus pools than in H. anatolicum pools (4%, 4.44%, and 0.10-8.79%) in this study. Fifty-one tick pools were found to harbor two pathogens, while nineteen tick pools were detected to have the three pathogens. Our findings indicate the presence of Rickettsia spp., Theileria spp., and Anaplasma spp. potentially transmitted by H. anatolicum and Rh. turanicus in sheep in southern Xinjiang, China.
