在坦桑尼亚Dodoma Rural(5)和Bagamoyo(1)地区的6个村庄对水、牛和人类中水生人畜共患病病原体的流行情况进行了研究。在水源中筛选粪便大肠菌群、嗜热弯曲杆菌、沙门氏菌、隐孢子虫和贾第鞭毛虫。还对牛和人的粪便样本进行了上述特定病原体分析。结果表明，70.8% （n = 48）的水源被粪便大肠菌群污染。Dodoma农村和Bagamoyo地区的两个村庄的水源也受到了贾第鞭毛虫的污染。两个研究区牛空肠弯曲杆菌总体流行率为2.3% (n = 942)，每个村至少有一头牛感染空肠弯曲杆菌。在Dodoma区的3个村庄，在0.5% （n = 942）接受检查的牛中检出细小隐孢子虫。在Dodoma农村地区Chalinze村，沙门氏菌仅在1.4% （n = 144）的牛中检出，而在Bagamoyo地区Chamakweza村，仅在1.5% （n = 202）的牲畜中检出兰布拉氏杆菌。在研究地区的三个卫生中心进行筛查的人中，有9人（1.9%）感染了C型空肠，3.7% （n = 484）的人患有C型幼卵囊。在巴加莫约区Chalinze卫生中心接受筛查的202人中，有2.5%的人发现了兰螺旋体。二级数据分析显示，在这两个地区，与肠道疾病相关的临床主诉全年都很普遍，5岁患者的患病率从1%到25%不等。总之，这项研究强调了可能存在的公共卫生风险，这可能与饲养动物和人类与动物共享水源有关。(c) 2005 Elsevier Ltd版权所有。
A study on the prevalence of water-borne zoonotic pathogens in water, cattle and humans was conducted in six villages in Dodoma Rural (5) and Bagamoyo (1) districts, Tanzania. Water sources were screened for faecal coliform organisms, thermophilic Campylobacter, Salmonella, Cryptosporidium and Giardia. Faecal samples from cattle and humans were also analysed for the above specific pathogens. Results indicate that 70.8% (n = 48) of the water sources screened were contaminated with faecal coliform organisms. Water sources in two villages, one each in Dodoma Rural and Bagamoyo districts were also contaminated with Giardia lamblia. The overall prevalence of Campylobacter jejuni in cattle in the two study areas was 2.3% (n = 942) and at least one animal in each village was infected with C jejuni. Cryptosporidium parvum was detected in 0.5% (n = 942) of the cattle examined in three villages in Dodoma district. Salmonella spp. was demonstrated in only 1.4% (n = 144) of the cattle in Chalinze village in Dodoma Rural district while G. lamblia was only detected in 1.5% (n = 202) of the animals examined in Chamakweza village in Bagamoyo district. Nine (1.9%) of the people screened at three heath centres in the study areas were infected with C jejuni while 3.7% (n = 484) of the people had C parvurn oocysts. G. lamblia was detected in 2.5% of the 202 people screened at the Chalinze health centre in Bagamoyo district. Analysis of the secondary data revealed that clinical complaints related to enteric diseases were prevalent in humans in the two areas throughout the year and the prevalence varied from about 1% to 25% in both = 5 years patients. In conclusion, this study has highlighted the possible public health risks, which may be associated with keeping of animals and sharing of water sources between humans and animals.
