Helminth Infections in Chickens from Tennessee

Abstract

BY MEANS of a survey, initiated in 1945, an effort is now being made to establish the nature and the number of helminth infections in chickens in Tennessee. In 1946 the survey was extended from East Tenessee to cover the entire State, although no collections have been made from the south-western counties. As in 1945, chickens examined were those which actually appeared on the various poultry markets, and an effort was made to collect all the worms of each species in an infected bird.It has been recorded (Todd, 1946, Poultry Sci. 25:424–432) that 390 chickens were examined in 1945, and of this number 370 (95 percent) were infected by 1 or more of 17 species of helminths. A total of 33,018 worms were collected, an average of 89.2 worms in an infected bird. The smallest number of worms found in one chicken in 1945 was 1; the largest .
