Helminths were examined from 145 scaled quail (Callipepla squamata) collected during the 2012-2013, 2013-2014 and 2014-2015 hunting seasons from a semi-arid region of Texas that spans four ecoregions. Helminth infracommunities were species poor, averaging 1.7 (range 1-4) species. Six species occurred within the component community of which one (Oxyspirura petrowi) is known to be pathogenic to quail. Aulonocephalus pennula was most abundant (9991 individuals, 95% of total) followed by O. petrowi (391 individuals, 4%). Each of the remaining four species was rare (≤21% prevalence) and contributed few individuals (<1%). In the High Plains ecoregion, prevalence of O. petrowi was higher in host collections made during the 2013-2014 hunting season than either hunting seasons 2012-2013 or 2014-2015 and was higher in the High Plains ecoregion than the Edwards Plateau ecoregion during the 2013-2014 hunting season. Mean abundance of A. pennula and O. petrowi was higher in scaled quail from the High Plains ecoregion than the Edwards Plateau ecoregion. Our results provide new information about helminth fauna in scaled quail, persistence of indirect lifecycle helminth species within a semi-arid region, and the occurrence of pathogenic helminth species within this host species.
在2012 - 2013年、2013 - 2014年和2014 - 2015年狩猎季节，从德克萨斯州一个跨越四个生态区的半干旱地区收集了145只鳞斑鹑（Callipepla squamata），并对其体内的蠕虫进行了检查。蠕虫群落物种较少，平均有1.7种（范围为1 - 4种）。在组成群落中有六种物种，其中一种（彼得罗维尖旋尾线虫）已知对鹌鹑具有致病性。羽冠异刺线虫最为丰富（9991只，占总数的95%），其次是彼得罗维尖旋尾线虫（391只，占4%）。其余四种物种均很罕见（患病率≤21%），个体数量很少（<1%）。在高平原生态区，2013 - 2014年狩猎季节收集的宿主中彼得罗维尖旋尾线虫的患病率高于2012 - 2013年或2014 - 2015年狩猎季节，并且在2013 - 2014年狩猎季节，高平原生态区的患病率高于爱德华兹高原生态区。高平原生态区鳞斑鹑体内羽冠异刺线虫和彼得罗维尖旋尾线虫的平均丰度高于爱德华兹高原生态区。我们的研究结果提供了有关鳞斑鹑体内蠕虫动物群、半干旱地区间接生命周期蠕虫物种的持久性以及该宿主物种内致病性蠕虫物种出现情况的新信息。
