Between 2002 and 2003 the Authors analyzed stool specimens of 1,989 subjects, 966 children (1-14 years old) and 1,023 adults, to investigate for intestinal protozoa too: 380 children and 656 adults with intestinal aspecific troubles, 546 children and 291 adults with acute diarrhoea, 40 children and 76 adults with prolonged diarrhoea. G. duodenalis prevailed in 1.8% of all cases (0.2% among children and 3.2% among adults), D. fragilis in 4.1% (0.6% and 7.3% respectively). Other pathogenic parasites were very rare. Only B. hominis (opportunistic/saprophytic protozoon) or other commensal protozoa were observed, also associated with D. fragilis and/or G. duodenalis. Among subjects suffering from intestinal aspecific troubles, G. duodenalis prevailed in 3.7% and D. fragilis in 8.7% of adults; both protozoa were observed in 0.5% of children each one. Among acute diarrhoeas G. duodenalis was observed in 1.7% of adults and never in children, D. fragilis in 4.5% and 0.4% respectively. Among prolonged diarrhoeas, G. duodenalis was observed in 5.3% of adults and never in children, D. fragilis in 6.6% of adults an in 5.0% of children. The Authors emphatyze the clinical importance of D. fragilis and the diagnostical importance of a permanent stain, like Giemsa, for a good and sure diagnosis.
2002年至2003年间，作者分析了1989名受试者的粪便样本，其中包括966名儿童（1至14岁）和1023名成年人，以调查肠道原生动物：380名患有肠道非特异性疾病的儿童和656名成年人，546名患有急性腹泻的儿童和291名成年人，40名患有持续性腹泻的儿童和76名成年人。十二指肠贾第虫在所有病例中占1.8%（儿童中为0.2%，成年人中为3.2%），脆弱双核阿米巴占4.1%（分别为0.6%和7.3%）。其他致病寄生虫非常罕见。仅观察到人芽囊原虫（机会性/腐生性原生动物）或其他共生原生动物，也与脆弱双核阿米巴和/或十二指肠贾第虫有关。在患有肠道非特异性疾病的受试者中，十二指肠贾第虫在成年人中占3.7%，脆弱双核阿米巴在成年人中占8.7%；两种原生动物在儿童中各占0.5%。在急性腹泻患者中，十二指肠贾第虫在1.7%的成年人中被观察到，儿童中未观察到，脆弱双核阿米巴分别在4.5%和0.4%的患者中被观察到。在持续性腹泻患者中，十二指肠贾第虫在5.3%的成年人中被观察到，儿童中未观察到，脆弱双核阿米巴在6.6%的成年人和5.0%的儿童中被观察到。作者强调了脆弱双核阿米巴的临床重要性以及吉姆萨等永久性染色剂对准确可靠诊断的诊断重要性。
