From May to August 1999, we evaluated 401 patients from a pediatric hospital of Havana City. One group was composed of 113 patients with diarrhea admitted to the Gastroenterology ward and a second consisted of 288 patients without diarrhea, admitted for other reasons, and hospitalized within the same time period. Three stool samples were collected from each child and were examined using three parasitological techniques. When we compared the frequency of parasite species between both groups, we found Cryptosporidium spp. and Cyclospora cayetanensis, only in the group of children with diarrhea (P < 0.01). However, no significant differences were found in the occurrence of the other intestinal parasites (P > 0.05). In addition, in those children infected with Cryptosporidium, the diarrhea had a more prolonged duration (P < 0.01), while those infected with Cyclospora, the abdominal cramps or pain, and acute diarrhea were more frequently detected (P < 0.01). Our results showed that emerging intestinal coccidia are pathogens strongly associated in this group of children with diarrhea.
1999年5月至8月，我们对哈瓦那市一家儿科医院的401名患者进行了评估。一组由113名因腹泻入住胃肠病科病房的患者组成，另一组由288名无腹泻、因其他原因在同一时期住院的患者组成。从每个儿童身上采集了三份粪便样本，并使用三种寄生虫学技术进行检查。当我们比较两组之间寄生虫种类的频率时，我们发现隐孢子虫属和卡耶塔环孢子虫仅在腹泻儿童组中存在（P<0.01）。然而，在其他肠道寄生虫的发生率上未发现显著差异（P>0.05）。此外，在感染隐孢子虫的儿童中，腹泻持续时间更长（P<0.01），而在感染环孢子虫的儿童中，更频繁地检测到腹部绞痛或疼痛以及急性腹泻（P<0.01）。我们的结果表明，新出现的肠道球虫是这组腹泻儿童中密切相关的病原体。
