Schistosoma nasale

Schistosoma nasale was identified in 1933 by Dr MAN Rao at Madras Veterinary College, Tamil Nadu, India as a casuasative agent for snoring disease in the cattle. The parasite and the disease has been reviewed by Dr MC Agrawal and Dr VS Alwar in 1992 in Helminthological Abstracts (Volume 61, page 373 to 384). Indoplanorbis exutus is the intermediate host for the parasite. The disease is affecting almost whole cattle population in the endemic area. The clinical symptoms include cauliflower like growth or granuloma in the nasale cavity associated with snoring sound and profuse mucopurulent discharge. Anthiomaline was the drug of choice but leading to relapse of the symptoms after two months of the treatment. Recently Dr MC Agrawal has successfully treated cases of nasal schistosomiasis by administering triclabendazole per os @ 20 mg/Kg body weight.
