Abstract

Cloacal swabs were collected from teal (Anas crecca, Anas cyanoptera, Anas discors), mottled duck (Anas fulvigula) and northern pintail (Anas acuta) in Brazoria County, Texas, USA, during February 2001, mottled ducks during August 2001, and blue-winged teal (A. discors) during February 2002. Prevalence of avian influenza virus (AIV) infections during each sampling period were 11, 0, and 15%, respectively. The hemagglutinin (H) subtypes H2 and H7 were detected in both years, while the H8 subtype was detected in 2001 and the H1 subtype was detected in 2002. Avian paramyxovirus type 1 (APMV-1) was isolated from 13% of mottled ducks sampled in August 2001 and 30.7% of teal in February 2002. The season of isolation of both viruses and the majority of the AIV subtypes detected in this study are not typical based on previous reports of these viruses from North American ducks.

摘要

2001年2月，在美国得克萨斯州布拉佐里亚县，从绿翅鸭（绿翅鸭、蓝翅鸭、赤膀鸭）、花脸鸭和针尾鸭采集泄殖腔拭子；2001年8月采集花脸鸭的拭子；2002年2月采集蓝翅鸭的拭子。每个采样期禽流感病毒（AIV）感染率分别为11%、0%和15%。两年均检测到血凝素（H）亚型H2和H7，2001年检测到H8亚型，2002年检测到H1亚型。从2001年8月采样的13%的花脸鸭和2002年2月30.7%的绿翅鸭中分离出1型禽副粘病毒（APMV-1）。根据此前北美鸭类这些病毒的报告，本研究中两种病毒的分离季节以及检测到的大多数AIV亚型并不典型。
