A prospective study was carried out to investigate the prevalence of Blastocystis hominis among random sample of apparently healthy food handlers. A total of 250 non Saudi males over 21 years of age were examined. Ninety (36%) had pathogenic and non pathogenic intestinal parasites. A total of 143 parasites were detected in their stool specimens. Twenty were B. hominis (13.99%) while other parasites were 123 (86.01%). B. hominis was found in 20 positive cases (22.22%) with an overall rate of 8%. Of these twenty cases, two had B. hominis as a sole parasite, twelve as a double infection and six as a triple infection. Other intestinal parasites were found, Giardia lamblia (16.8%), Entamoeba histolytica (10%), E. coli (6.4%), Chilomastix mesnili (5.6%), Trichomonas hominis (1.2%), and Endolimax nana (0.8%). The helminths were represented by Ascaris lumbricoides (4%), Hymenolepis nana (3.2%), Enterobius vermicularis (1.2%) and Trichocephalus trichiura (0.8%). No doubt, B. hominis should be in mind of parasitologists and physicians when dealing with patients with gastrointestinal troubles.
开展了一项前瞻性研究，以调查表面健康的食品处理人员随机样本中人体芽囊原虫的流行情况。共检查了250名21岁以上的非沙特男性。90人（36%）感染了致病性和非致病性肠道寄生虫。在他们的粪便标本中总共检测到143种寄生虫。其中20种为人体芽囊原虫（13.99%），其他寄生虫为123种（86.01%）。在20例阳性病例中发现了人体芽囊原虫（22.22%），总体感染率为8%。在这20例病例中，2例仅感染人体芽囊原虫，12例为双重感染，6例为三重感染。还发现了其他肠道寄生虫，蓝氏贾第鞭毛虫（16.8%）、溶组织内阿米巴（10%）、大肠埃希菌（6.4%）、梅氏唇鞭毛虫（5.6%）、人毛滴虫（1.2%）和微小内蜒阿米巴（0.8%）。蠕虫包括蛔虫（4%）、微小膜壳绦虫（3.2%）、蛲虫（1.2%）和鞭虫（0.8%）。毫无疑问，在处理胃肠道疾病患者时，寄生虫学家和医生应考虑到人体芽囊原虫。
