Cloacal and tracheal swabs were collected from 1,409 hunter-killed ducks in Cameron Parish, Louisiana, during the 1986 and 1987 waterfowl seasons. Thirty avian paramyxoviruses (PMV's) were isolated from 605 blue-winged teal (Anas discors), 75 mottled ducks (A. fulvigula), 375 gadwalls (A. strepera), 334 green-winged teal (A. crecca), and 20 mallards (A. platyrhynchos). Prevalence of PMV decreased (P = 0.042) from September (4%) through November (2%) to December and January (1%). Juveniles had a higher prevalence of PMV (P less than 0.0001) than adults. An isolate from resident mottled ducks documents transmission of PMV's on the coastal wintering areas of Louisiana. The four serotypes isolated, PMV-1, PMV-4, PMV-6, and PMV-8, were typical of PMV's commonly associated with free-living waterfowl.
1986年和1987年水鸟季节期间，从路易斯安那州卡梅伦教区1409只被猎人捕杀的鸭子身上采集了泄殖腔和气管拭子。从605只蓝翅鸭（绿翅鸭）、75只花脸鸭、375只赤膀鸭、334只绿翅短颈鸭和20只绿头鸭中分离出30株禽副粘病毒（PMV）。PMV的流行率从9月（4%）到11月（2%）再到12月和1月（1%）呈下降趋势（P = 0.042）。幼鸭的PMV流行率高于成年鸭（P < 0.0001）。从当地花脸鸭中分离出的一株病毒证明了PMV在路易斯安那州沿海越冬地区的传播。分离出的四种血清型，PMV-1、PMV-4、PMV-6和PMV-8，是通常与野生水鸟相关的PMV典型类型。
