Abstract

Gizzard helminths were examined in 100 (50 adult, 50 juvenile) female northern pintails ( Anas acuta). Sixty-three individual helminths, representing 5 species ( Amidostomum acutum, Echinuria uncinata, Epomidiostomum uncinatum, Streptocara crassicauda, and Gastrotaenia cygni) were found. Twenty-seven northern pintails were infected with 1-3 helminth species and averaged 1.4 species. Overall, A. acutum and G. cygni were the most prevalent and abundant species (20%, n = 31 and 10%, n = 25, respectively), followed by S. crassicauda (5%, n = 5), E. uncinata (1%, n = 1), and E. uncinatum (1%, n = 1). Intensity of infection for A. acutum, E. uncinata, E. uncinatum, S. crassicauda, and G. cygni was 1.6 ± 0.3 [SE], 1.0 ± 0, 1.0 ± 0, 1.0 ± 0, and 2.5 ± 0.6, respectively. Our findings represent new information about gizzard helminth infections in northern pintails wintering along the Texas coast.

摘要

对100只（50只成年、50只幼年）雌性针尾鸭（Anas acuta）的肌胃寄生虫进行了检查。发现了63条个体寄生虫，分属5个物种（尖锐中殖孔吸虫、有钩棘头虫、钩状后殖孔吸虫、粗尾链体吸虫和天鹅胃带绦虫）。27只针尾鸭感染了1至3种寄生虫，平均感染1.4种。总体而言，尖锐中殖孔吸虫和天鹅胃带绦虫是最常见且数量最多的物种（分别为20%，n = 31和10%，n = 25），其次是粗尾链体吸虫（5%，n = 5）、有钩棘头虫（1%，n = 1）和钩状后殖孔吸虫（1%，n = 1）。尖锐中殖孔吸虫、有钩棘头虫、钩状后殖孔吸虫、粗尾链体吸虫和天鹅胃带绦虫的感染强度分别为1.6 ± 0.3 [标准误]、1.0 ± 0、1.0 ± 0、1.0 ± 0和2.5 ± 0.6。我们的研究结果代表了关于在得克萨斯州海岸越冬的针尾鸭肌胃寄生虫感染的新信息。
