Objective: To investigate seasonal prevalence of parasitic infection of yak in two yak rearing\uddistricts (West Kameng and Tawang) of Arunachal Pradesh, India. Method: Study was based\udon identification of parasitic ova/oocysts through coproscopy and isolation and identification\udof organisms on necropsy. During the period under report a total of 895 faecal samples were\udcollected and samples were examined both by floatation and sedimentation techniques. Results:\udOut of 895 sample faecal samples, 5.47% samples were positive for protozoa and helminth\udinfections. Infection was the highest during spring followed by rainy, autumn and winter seasons.\udThe highest prevalence was of Strongyle (51.02%) followed by Eimeria (34.69%), Trichuris globulosa\ud(14.28%), Strongyloides (10.20%), Dicrocoelium and Mammomonogamus laryngeus (8.16% each)\udamphistome and Toxocara vitulorum (6.12% each) and Fasciola gigantica (4.08%). On necropsy\udunilocular cysts of Echinococcus granulosus and adult worms of Fasciola gigantica were isolated\udand identified. Conclusions: Analysis of data revealed that, infection was more in unorganised\udherd compared to organised herd. In this communication report of Mammomonogamus laryngeus\udseems to be the first report from India
