Experimental ancylostomiasis in chickens: effect of various dose of infective Ancylostoma caninum larvae on their migration and distribution.
White leghorn chickens, when infected with repeated doses of Ancylostoma caninum larvae, expel the larvae at a faster rate than when infected with a single dose. This suggests that the initial dose induces some resistance in the host. An initial dose of 1000 and 2000 larvae, followed by a 2nd dose of the same order, induces resistance in the alimentary tract causing the entire larval burden either to migrate to other tissues (organs) or to be expelled in 24 h.
