2005年1月，泰国中部一所小学进行了肠道寄生虫感染调查。在 675 个粪便样本中，芽囊原虫的患病率为 18.9%。芽囊菌的遗传特征显示为亚型 1 (77.9%) 和亚型 2 (22.1%)。对这所学校的供水系统进行了研究，以寻找芽囊菌的可能来源。一份水样中的芽囊菌被鉴定为亚型 1，其小亚基 (SSU) 核糖体 RNA (rRNA) 基因的核苷酸序列与学童感染的芽囊菌的核苷酸序列 100% 相同。我们的信息支持了该人群中存在水传播的证据。
In January 2005, a survey of intestinal parasitic infections was performed in a primary school, central Thailand. Of 675 stool samples, Blastocystis was identified with a prevalence of 18.9%. Genetic characterization of Blastocystis showed subtype 1 (77.9%) and subtype 2 (22.1 %). Study of the water supply in this school was performed to find the possible sources of Blastocystis. Blastocystis from one water sample was identified as subtype 1, which had a nucleotide sequence of small subunit (SSU) ribosomal RNA (rRNA) gene that was 100% identical to that of Blastocystis infected in schoolchildren. Our information supports the evidence of water-borne transmission in this population.
