Morphological characterization of nematodes of the genera Capillaria, Acuaria, Amidostomum, Streptocara, Heterakis, and Ascaridia isolated from intestine and gizzard of domestic birds from different regions of the temperate Kashmir valley.

During a random survey of parasitisation of poultry birds of Kashmir, conducted for 3 years more than 300 poultry birds were randomly collected from different parts of the Kashmir valley and were examined for the helminth parasites. The most dominant group of parasites which was parasitizing the poultry birds was found to be the Cestode, whose prevalence in the infected birds was 76.9 %. Nematodes were found to be the second dominant group of parasites after cestodes with the prevalence of 70 %. Among the different species of nematodes Heterakis gallinae were found infecting almost all the birds autopsied. The highest intensity of H. gallinae might be because of the fact that it requires cockroaches, beetles and grasshoppers as intermediate hosts in addition of having a direct life cycle. Nematodes which were recovered from the intestine and gizzard of the birds belong to the genera Capillaria, Acuaria, Amidostomum, Streptocara, Heterakis, and Ascaridia.
