隐孢子虫。引起暴发性腹泻和慢性感染的免疫力低下者,尤其是人类免疫缺陷病毒感染者。缺乏体外培养和合适的动物模型,限制了有效治疗的发展。我们描述了两种新的慢性症状性隐孢子虫病小鼠模型,分别发生在成年无菌小鼠和T细胞亚群耗尽的小鼠中。大多数成年裸鼠发生进行性感染,在4个月内死亡;少数发展为稳定感染。症状包括脱水、体重减轻、间歇性腹泻和黄疸。在稳定期感染中,病变和微生物局限于肠道,而在其他感染中,病变累及肝胆树和胰腺。来自组织相容、隐孢子虫免疫的小鼠的淋巴细胞治愈了感染的裸鼠。在新生儿感染的BALB/c小鼠中,单独使用抗CD4单抗或同时使用抗CD8单抗均可发生相同的感染;当停止单抗治疗时,小鼠被治愈。这些模型将在定义允许慢性隐孢子虫病发展的免疫缺陷和评估治疗方式方面有用。
Cryptosporidium sp. causes fulminant diarrhea and chronic infection in immunocompromised, particularly human immunodeficiency virus-infected, persons. The lack of in vitro cultivation and a suitable animal model has limited development of effective treatment. We describe two new mouse models of chronic symptomatic cryptosporidiosis in adult athymic mice and in T-cell subset-depleted mice. A progressive infection, fatal within 4 months, occurred in most adult athymic mice; a few developed stable infections. Symptoms included dehydration, weight loss, intermittent diarrhea, and jaundice. Pathologic abnormalities and organisms localized in the intestine in stable infections but involved the hepatobiliary tree and pancreas in others. Lymphoid cells from histocompatible, Cryptosporidium sp.-immune mice cured infected nude mice. Identical infections occurred in neonatally infected BALB/c mice treated with anti-CD4 monoclonal antibodies alone or also with anti-CD8 monoclonal antibodies; the mice were cured when the monoclonal antibody treatments were stopped. These models will be useful in definition of the immune defects that permit chronic cryptosporidiosis to develop and in assessment of treatment modalities.
