Quantitative and qualitative analyses of the intestinal bacterial flora of Canada geese and whistling swans were carried out with the finding that wild birds harbor significantly more fecal coliforms than fecal streptococci. The reverse was typical of captive and fasting birds. Neither Salmonella spp. nor Shigella spp. were isolated from 44 migratory waterfowl that were wintering in the Chesapeake Bay region. Enteropathogenic Escherichia coli were detected in seven birds. Geese eliminated 10(7) and swans 10(9) fecal coliforms per day. Results of in situ studies showed that large flocks of waterfowl can cause elevated fecal coliform densities in the water column. From the data obtained in this study, it is possible to predict the microbial impact of migratory waterfowl upon aquatic roosting sites.
对加拿大鹅和啸天鹅的肠道菌群进行了定量和定性分析,结果发现野生鸟类携带的粪大肠菌群明显多于粪链球菌。圈养和禁食鸟类的情况则相反。在切萨皮克湾地区越冬的44只迁徙水禽中,均未分离出沙门氏菌属和志贺氏菌属。在7只鸟类中检测到了肠致病性大肠杆菌。鹅每天排出10⁷个粪大肠菌群,天鹅每天排出10⁹个粪大肠菌群。原位研究结果表明,大量水禽会导致水柱中粪大肠菌群密度升高。根据本研究获得的数据,可以预测迁徙水禽对水生栖息地点的微生物影响。
