Abstract

abstract: The eyes, breast muscle, and internal organs of 128 hunter-shot northern bobwhites (Colinus virginianus) from the Rolling Plains ecoregion of Texas, U.S.A., were examined for helminths. Six species of nematodes, 1 acanthocephalan, and 1 cestode were found in 120 bobwhites, representing 18,205 helminth individuals. Aulonocephalus pennula was the most common (91% prevalence) and numerically abundant (91% of all individuals) species, followed by Oxyspirura petrowi (66% prevalence and 7% of all individuals). Each of the remaining 6 species was rare (<24% prevalence). Species richness was low compared to studies from the southeastern United States. Of the species found, Tetrameres pattersoni, Cheliospirura spinosa, and O. petrowi are known to cause pathology in quail. Prevalence and mean abundance of O. petrowi were higher in adults than juveniles. Host age did not influence prevalence of A. pennula, and host sex did not influence prevalence or mean abundance of A. pennula or O. petrowi.
美国德克萨斯州起伏平原北部山齿鹑(Colinus virginianus)的蠕虫调查
对美国德克萨斯州滚动平原地区128只猎猎北长齿白鲨(Colinus virginianus)的眼睛、胸部肌肉和内脏器官进行了蠕虫检查。120只山齿鲨共检出线虫6种、棘头虫1种、囊虫1种,共18205只。冠状黄头藻(Aulonocephalus pennula)是最常见的物种(占总个体的91%),数量最多(占总个体的91%),其次是尖螺旋藻(Oxyspirura petrowi)(占总个体的66%和7%)。其余6种均罕见(患病率<24%)。与美国东南部的研究相比,物种丰富度较低。在发现的物种中,已知会引起鹌鹑病理的有斑纹四目鼠、棘足螺和O. petrowi。成虫的患病率和平均丰度高于幼虫。寄主年龄不影响圆甲的流行度,寄主性别不影响圆甲的流行度和平均丰度。
