Three cases of muscular sarcocystosis from West Malaysia are reported. The morphological features of the parasites from these three cases are similar to the eight cases previously reported from this country. A review of this total of eleven cases of muscular sarcocystosis showed that they were all incidental findings, where man acted as intermediate hosts of as yet unknown Sarcocystis spp. These cases of muscular sarcocystosis were probably zoonotic in origin and associated with close contact with definitive hosts (both domestic and wild animals) thus permitting the contamination of food and drink with sporocysts shed by these definitive hosts. These infections were probably acquired locally as most of the subjects were born in Malaysia and none had ever left the country to stay elsewhere. Eight of the eleven cases reported were associated with malignancies, especially of the tongue and nasopharynx.
报告了来自马来西亚西部的3例肌肉肉孢子虫病病例。这3例病例中寄生虫的形态特征与该国先前报告的8例病例相似。对这总共11例肌肉肉孢子虫病病例的回顾表明，它们均为偶然发现，其中人类作为尚未明确的肉孢子虫属的中间宿主。这些肌肉肉孢子虫病病例可能起源于动物传染，与与终末宿主（包括家畜和野生动物）密切接触有关，从而使食物和饮料被这些终末宿主排出的孢子囊污染。这些感染可能是在当地获得的，因为大多数受试者出生在马来西亚，且没有人曾离开该国前往其他地方居住。报告的11例病例中有8例与恶性肿瘤有关，尤其是舌和鼻咽癌。
