Cyclospora spp. is a protozoan parasite responsible for significant gastrointestinal disease in patients infected with the human immunodeficiency virus. We report the clinical features of two patients with chronic diarrhea and intestinal cyclosporosis caused by Cyclospora cayetanensis. The average value for CD4 count in these patients was lower than or equal to 100 cells/mm3. The oocysts were detected in smears from stool samples stained with modified acid-fast or safranin technique. Light microscopy revealed parasites in the enterocytes and these parasites were associated with villous atrophy. Cyclospora cayetanensis infection might be an important cause of diarrhea in patients with AIDS in Argentina.
环孢子虫属是一种原生动物寄生虫，可导致感染人类免疫缺陷病毒的患者出现严重的胃肠道疾病。我们报告了两例由卡耶塔环孢子虫引起的慢性腹泻和肠道环孢子虫病患者的临床特征。这些患者的CD4细胞计数平均值低于或等于100个细胞/立方毫米。在用改良抗酸染色或番红染色技术染色的粪便样本涂片中检测到了卵囊。光学显微镜检查发现肠上皮细胞中有寄生虫，这些寄生虫与绒毛萎缩有关。在阿根廷，卡耶塔环孢子虫感染可能是艾滋病患者腹泻的一个重要原因。
