Trematodes of Fish-Eating Birds of the Western Region of Azerbaijan
Abstract
In 2017-2020 in the Western region of Azerbaijan 94 fish-eating birds of 21 species were examined using the full helminthological autopsy method, 46 species of trematodes belonging to 3 orders, 12 families and 26 gender were identified. Of these, 1 species was recorded in 8 bird species, 2 species in 5 bird species, 4 species in 4 bird species, 8 species in 3 bird species, 20 species in 2 bird species and 11 species in only 1 bird species. Four species of trematodes found in the liver and bile ducts of birds, three in the kidneys and 1-2 in each of the other organs. Fourteen species of trematodes have been recorded in the common gull, 13 in the great egret, 12 in the little egret, 11 in the herring gull, 10 in the little tern, 9 in the great cormorant, 9 in the pygmy cormorant, 8 in the little tern, 7 in the cattle egret, 6 in the great egret, and 1 in the herring gull. Of the trematodes obtained, one species can parasitize the human intestine, cercariae of 2 species attack humans in water and cause nonspecific cercariosis, 2 species cause disease in birds, and 4 species cause disease in fish.
