During 2 bathing seasons, 1978 and 1979, water samples were collected with intervals of 2 weeks from 17 marine bathing areas situated on the coast of the island of Fyn. Quantitative examinations for coliphages and fecal coliforms were carried out. Coliphages were present in approximately 50% of the samples. 75% of the positive samples contained less than or equal to 10 coliphages per 100 ml. 6 samples were found with greater than 100 coliphages per 100 ml. A positive correlation between coliphage and fecal coliform concentrations was demonstrated. The ratios of fecal coliforms to coliphages varied only little between individual sampling stations. The mean ratio was 1.9 and 2.0 for the 2 sampling periods. The mean concentration of fecal coliforms was gradually increasing from 2.4/100 ml in May to 7.2/100 ml in September. Conversely the coliphage concentrations were quite uniform during the bathing seasons. As a result of those 2 trends, the fecal coliform/coliphages ratio increased during the seasons from 0.86 to 3.13. Finally, the potential value of coliphages as an indicator of pathogenic microorganisms in marine bathing areas is discussed.
在1978年和1979年的两个游泳季节里,每隔两周从菲英岛海岸的17个海水浴场采集水样。对大肠杆菌噬菌体和粪大肠菌群进行了定量检测。约50%的样本中存在大肠杆菌噬菌体。75%的阳性样本中每100毫升含有的大肠杆菌噬菌体小于或等于10个。发现有6个样本中每100毫升的大肠杆菌噬菌体超过100个。结果表明大肠杆菌噬菌体与粪大肠菌群浓度之间存在正相关。各个采样点之间粪大肠菌群与大肠杆菌噬菌体的比例变化很小。两个采样期的平均比例分别为1.9和2.0。粪大肠菌群的平均浓度从5月的2.4/100毫升逐渐增至9月的7.2/100毫升。相反,游泳季节期间大肠杆菌噬菌体的浓度相当稳定。由于这两种趋势,粪大肠菌群/大肠杆菌噬菌体的比例在季节期间从0.86增至3.13。最后,讨论了大肠杆菌噬菌体作为海水浴场致病微生物指标的潜在价值。
