Abstract: A survey was conducted in seven districts of upper Assam for a period of one year from June, 2016 to May, 2017 to study the prevalence of helminths parasites of domestic ducks in upper Assam. Examination of 724 faecal samples collected from different localities of upper Assam revealed 333 samples to be positive for helminths with overall prevalence of 45.99 per cent. Out of the positive samples, total 2 faecal samples were found positive for cestodes, 171 for trematodes and 160 for nematodes with incidence of 0.60 per cent, 51.35 per cent and 48.05 per cent. Post mortem examination of 774 carcasses of ducks from different localities of different districts in upper Assam revealed 518 carcasses to be positive for helminthic infections. The overall prevalence of helminths was recorded as 66.93 per cent. 232 carcasses were found positive for cestodes (44.79%), 241 for trematodes (46.52%) and 45 for nematodes (8.69%). On the basis of morphological studies, 7 different species of cestodes and 1 larval stage of cestode, 8 different species of trematodes and 5 different species of nematodes were identified and recorded. Highest incidence of cestodes was recorded with Hymenolepis collaris (35.78%) followed by Hymenolepis carioca (35.34%), Fimbriaria fasciolaris (22.41%), Hymenolepis lanceolata (1.74%), Raillietina tetragona (1.29%), Raillietina echinobothrida (1.29%) and Raillietina cesticillus (1.29%) and lowest with plerocercoid (0.86%). Highest incidence of trematodes was recorded with Echinostoma revolutum (24.07%), Hypoderaeum sp. (18.67%), Psiloritis sp. (18.67%), Echinostoma paraulum (16.60%), Paramphistomum sp. (10.79%), Prosthogonimus sp. (8.30%), Tracheophilus cymbius (2.07%) and Psilochasmus sp. (0.83%). Highest incidence of nematodes was recorded with Tetrameres sp. (57.78%), Heterakis gallinarum (17.78%), Heterakis dispar (17.78%), Strongyloides avium (4.44%) and Porrocaecum sp. (2.22%). Hymenolepis carioca, Hymenolepis lanceolata, Raillietina tetragona, Hypoderaeum sp., Echinostoma paraulum, Prosthogonimus sp., Psilochasmus sp. and Heterakis dispar were first time reported from Assam in duck.
