The presence of Salmonella and its relationship with indicators of faecal pollution was investigated in aquatic habitats. The highest frequency was obtained in rivers (58.7% of samples) followed by freshwater reservoirs (14.8%) and sea water (5.9%). The sporadic presence of Salmonella (< 30%) on beaches with low concentrations of faecal streptococci (mean 25 CFU (100 ml)-1) may represent a potential risk for bathers in agreement with data found in previous epidemiological studies. Absence of Salmonella was observed only on beaches with very low densities (CFU (100 ml)-1) of indicator organisms (25 total coliforms, 13 faecal coliforms and 17 faecal streptococci).
在水生栖息地调查了沙门氏菌的存在情况及其与粪便污染指标的关系。河流中的检出频率最高（占样本的58.7%），其次是淡水水库（14.8%）和海水（5.9%）。在粪便链球菌浓度较低（平均25 CFU(100 ml)-1）的海滩上偶尔出现沙门氏菌（<30%），这可能对游泳者构成潜在风险，这与之前流行病学研究的数据一致。仅在指示生物密度极低（CFU(100 ml)-1）（25个总大肠菌群、13个粪大肠菌群和17个粪便链球菌）的海滩上未观察到沙门氏菌。
