Stool samples were collected during August 1994 from seventy rural Maasai children under the age of five years who were living in the Maasailand region of the Kenyan Rift Valley. Microbiological analysis was carried out on these samples to identify which intestinal pathogens were present among the infant population of the Maasai. Of the samples studied 54% were pathogen positive. The most common pathogen isolated was Giardia lamblia which was detected in 31% of the samples. Other pathogens that were detected include: Entamoeba histolytica (23%), Enteropathogenic Escherichia coli (13%), Strongyloides stercoralis (4%), Blastocystis hominis (3%) and Cryptosporidium sp (3%). Although all samples were screened for Campylobacter and rotavirus, neither pathogen was detected. Water samples were taken from all the water sources in the study area and analysed microbiologically. Results showed that all the sources were contaminated with the faecal E. coli whose populations ranged from 14 CFU/100 ml to greater than 1800 CFU/100ml.
1994年8月，从肯尼亚裂谷地区马赛兰地区70名5岁以下的农村马赛儿童中采集了粪便样本。对这些样本进行了微生物分析，以确定马赛婴儿群体中存在哪些肠道病原体。在所研究的样本中，54%呈病原体阳性。分离出的最常见病原体是蓝氏贾第鞭毛虫，在31%的样本中被检测到。检测到的其他病原体包括：溶组织内阿米巴（23%）、致病性大肠杆菌（13%）、粪类圆线虫（4%）、人芽囊原虫（3%）和隐孢子虫属（3%）。尽管对所有样本都进行了弯曲杆菌和轮状病毒筛查，但均未检测到这两种病原体。从研究区域的所有水源采集了水样并进行了微生物分析。结果表明，所有水源都被粪便大肠杆菌污染，其数量范围从14 CFU/100毫升到大于1800 CFU/100毫升。
