Abstract

Macrocysts of a protozoan parasite, Sarcocystis sp., were found in 28 of 173 American black ducks (Anas rubripes) examined during winters 1984-1985, 1985-1986 and 1986-1987 in south coastal New Jersey (USA). No macrocysts were detected in 80 juvenile black ducks. In adults, the prevalence of macrocysts increased from 3% (1 of 37) in 1984-1985, to 36% (12 of 33) in 1985-1986, and 65% (15 of 23) in 1986-1987. This increase could result in a greater number of harvested birds being discarded, or a change in the attitudes of waterfowl hunters towards black ducks.

摘要

1984 - 1985年、1985 - 1986年和1986 - 1987年冬季，在美国新泽西州南部沿海对173只美洲黑鸭（Anas rubripes）进行检查时，发现其中28只感染了一种原生动物寄生虫——肉孢子虫属的大囊。在80只幼年黑鸭中未检测到任何大囊。在成年黑鸭中，大囊的感染率从1984 - 1985年的3%（37只中有1只），上升到1985 - 1986年的36%（33只中有12只），以及1986 - 1987年的65%（23只中有15只）。这种感染率的上升可能会导致更多被捕获的黑鸭被丢弃，或者使水禽猎人对黑鸭的态度发生改变。
