Summary Protostrongylids, small nematode lungworms, are an integral part of the wild ruminant helminth community, which can damage animals’ health when they are held in captivity or semi-captive conditions. The Sahelo-Saharan antelope species dorcas gazelle (Gazella dorcas), the scimitar-horned oryx (Oryx dammah), and the addax (Addax nasomacculatus), reintroduced to Souss-Massa National Park in Morocco, could be host to many species of Protostrongylids. This study was conducted from January to July 2015 to identify infecting parasite species, and determine their prevalence and abundance in all three antelope species. A total of 180 individual fecal samples were collected, morphologically examined by the Baermann technique, and molecularly identified by PCR amplification and sequencing of the second internal transcribed spacer region of the rDNA (ITS-2). Two parasite species were found in the three antelope populations: Muellerius capillaris and Neostrongylus linearis. The prevalence scores recorded for M. capillaris were 98.40 % in the addax, 96.70 % in dorcas gazelle, and 28.40 % in the oryx. The prevalence rates of N. linearis were 60 % in the addax, 23.40 % in dorcas gazelle, and 90 % in the oryx. Excreted larvae were quantified by LPG (larvae per gram) counting: for M. capillaris, the LPG mean values were 92.94 in the addax, 133.09 in dorcas gazelle, and 1.48 in the oryx; and for N. linearis, the LPG mean values were 6.02 in the addax, 1.37 in dorcas gazelle, and 32.81 in the oryx. These findings indicate that the three species of antelopes are infected with Muellerius capillaris and Neostrongylus linearis to varying degrees in intensity and prevalence.

苏斯-马萨国家公园（摩洛哥）羚羊原圆线虫感染的粪便学调查

摘要 原圆线虫是一种小型线虫肺虫，是野生反刍动物蠕虫群落的重要组成部分，当动物处于圈养或半圈养条件下时，会损害动物的健康。重新引入摩洛哥苏斯-马萨国家公园的萨赫勒-撒哈拉羚羊物种多卡斯羚羊 (Gazella dorcas)、弯角羚羊 (Oryx dammah) 和阿达克斯 (Addax nasomacculatus) 可能是许多原圆线虫物种的宿主。这项研究于 2015 年 1 月至 7 月进行，旨在识别感染性寄生虫物种，并确定其在所有三种羚羊物种中的流行率和丰度。总共收集了 180 份粪便样本，通过 Baermann 技术进行形态学检查，并通过 PCR 扩增和 rDNA 第二内转录间隔区 (ITS-2) 测序进行分子鉴定。在三个羚羊种群中发现了两种寄生虫：Muellerius capillaris 和 Neostrongylus Linearis。毛细血管菌的患病率在羚羊中为 98.40%，在羚羊中为 96.70%，在羚羊中为 28.40%。线状猪笼草的患病率在阿达克斯中为60%，在羚羊中为23.40%，在羚羊中为90%。通过LPG（每克幼虫）计数对排出的幼虫进行定量：对于M. capillaris，阿达克斯的LPG平均值为92.94，羚羊的LPG平均值为133.09，羚羊的LPG平均值为1.48；对于 N. Linearis，阿达克斯的 LPG 平均值为 6.02，多加羚羊为 1.37，羚羊为 32.81。这些发现表明，这三种羚羊都不同程度地感染毛细毛细线虫和线形新圆线虫。
