Abstract

Blastocystis is a ubiquitous intestinal protist of humans and animals. It is a genetically diverse organism whose part in the health and disease is still uncertain. This study provides information on Blastocystis STs in cattle, goats, and sheep in Perak, Malaysia, and the likely role of livestock animals in Blastocystis transmission to humans in Malaysia. Faecal samples from a total of 151 livestock animals consisting of cattle, goats, and sheep from Perak were examined by PCR analysis of the barcode region. Blastocystis ST10, ST14, and ST21 were identified in this study, and ST10 was common to all three ruminant livestock animal groups involved. Findings from previously published studies on Blastocystis in ruminant and non-ruminant livestock animals in Malaysia support indications that livestock animals may serve as reservoirs of human infections, being as one or more of the following Blastocystis subtypes: ST1, ST2, ST3, ST4, ST5, and ST6, have been isolated from both humans and livestock animals within similar regions of the country. Animal handlers are, therefore, advised to exercise proper hygiene to prevent possible transmission of Blastocystis from their animals, while further studies on the genetic variants of Blastocystis in farm animals and their keepers are required to better understand the role of these animals in human Blastocystis.

霹雳州反刍家畜囊虫亚型及马来西亚半岛家畜人畜共患病传播风险评估
囊虫是人类和动物普遍存在的肠道原生生物。它是一种基因多样化的生物,在健康和疾病中所起的作用仍不确定。本研究提供了马来西亚霹雳州牛、山羊和绵羊中囊虫STs的信息,以及牲畜在马来西亚囊虫传播给人类的可能作用。对霹雳州的牛、山羊和绵羊等151只家畜的粪便样本进行了条形码区域PCR分析。本研究鉴定出囊虫ST10、ST14和ST21,其中ST10在所有三个反刍家畜动物类群中都是常见的。先前发表的关于马来西亚反刍动物和非反刍牲畜中囊胚菌的研究结果表明,牲畜可能是人类感染的宿主,因为在该国类似地区,已从人类和牲畜中分离出以下一种或多种囊胚菌亚型:ST1、ST2、ST3、ST4、ST5和ST6。因此,饲养动物的人应保持良好的卫生习惯,以防止囊虫可能从他们的动物身上传播。同时,我们需要进一步研究农场动物及其饲养员的囊虫基因变异,以更好地了解这些动物在人类囊虫病中的作用。
