绵羊和山羊住肉孢子虫流行病学及分型研究进展

Epidemiology and classification of Sarcocystis in sheep and goat

动物住肉孢子虫病可引起畜牧养殖业的经济损失,影响食品质量安全,威胁人类健康。国际上已确定的绵羊(Ovis aries)住肉孢子虫有4种:S.tenella、S.arieticanis、S.gigantea、S.medusiformis,山羊(Capra hircus)住肉孢子虫有3种:S.capracanis、S.hircicanis、S.moulei。本文综述绵羊和山羊住肉孢子虫的生活史、国内和国际的流行情况、致病性、形态学特点和诊断方法,以期为中国绵羊和山羊住肉孢子虫的生物学特征研究及其诊断分型提供有力基础依据。

Sarcocystis could cause significant economic losses of animal husbandry, and threaten to public health and the quality of food safety. S. tenella, S. arieticanis, S. gigantea and S. medusi formis are four species Sarcocystis in sheep （Ovis aries）. While S. capracanis, S. hircicanis and S. moulei are three species of Sarcocystis in goat （Capra hircus）. The life cy cle, epidemiological, pathogenicity, morphological characteristics and diagnostic methods of sheep and goats were reviewed in this paper. The research of biological characteristics of Sarcocystis provides a powerful basis for diagnosis in sheep and goat in China.
