PATHOGENIC MECH IN IDIOPATHIC CHRONIC DIARRHEA OF RH MACAQUES AT THE CNPRC

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 而子项目的主要调查员可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 慢性特发性腹泻（ICD）是圈养猕猴管理中的一个主要健康和经济问题。 除了在不存在公认的肠道病原体的情况下结肠炎性细胞浸润的组织学表征外，尚未充分研究这种疾病的致病机制。 该项目的目标是系统地研究潜在的发病机制，包括食物过敏，对正常肠道细菌的过敏，以及结肠微生物群组成的不规则性（生态失调），在这种情况下的发展。该项目还将研究膳食补充锌和/或可溶性纤维在治疗和预防ICD中的治疗潜力。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. Chronic idiopathic diarrhea (ICD) is a major health and economic problem in the management of rhesus monkeys in captivity. The pathogenic mechanism(s)underlying this condition have not been well studied beyond histological characterization of the colonic inflammatory cellular infiltrate in the absence of recognized enteric pathogens. The goal of this project is to systematically investigate potential pathogenetic mechanisms, including food hypersensitivity, hypersensitivity to normal gut commensal bacteria, and irregularities in composition of colonic microflora (dysbiosis), in the development of this condition. This project will also investigate the therapeutic potential of dietary supplementation with zinc and/or soluble fiber in the treatment and prevention of ICD.
