Feces samples, inoculated with 10(6) Escherichia coli resistant to streptomycin and nalidixic acid and with 10(5) Salmonella typhimurium per g, were buried at five mountain field sites ranging from 2,005 to 2,730 m in elevation. Counts of each bacterium rose initially and then declined to 10(3) or 10(4) per g of feces in 8 weeks. The survival pattern was similar at all sites regardless of marked differences in elevation, soil, moisture, exposure, and vegetation. S. typhimurium numbers were consistently higher than E. coli numbers after week 3. The test encompassed most of the time that the area is snow-free and accessible for hiking. The results were judged to discredit the recommendation for shallow burial of feces and to indicate a potential health hazard under intensive use.
将每克粪便样本接种10⁶对链霉素和萘啶酸耐药的大肠杆菌以及10⁵鼠伤寒沙门氏菌,埋于海拔2005至2730米的五个山地现场。每种细菌的数量最初上升,然后在8周内降至每克粪便10³或10⁴。无论海拔、土壤、湿度、暴露情况和植被存在显著差异,所有现场的存活模式都相似。第3周后,鼠伤寒沙门氏菌的数量始终高于大肠杆菌的数量。该测试涵盖了该地区大部分无雪且可供徒步旅行的时间。结果被判定为不支持粪便浅埋的建议,并表明在高强度使用下存在潜在的健康危害。
