Comparative Survival of Faecal and Human Contaminants and Use of Staphylococcus aureus as an Effective Indicator of Human Pollution

摘要

Comparative survival tests of faecal coliforms (FC), faecal streptococci (FS), Salmonella spp. And Staphylococcus aureus grown in sea (35/100 of salinity) and brackish water (27/100 of salinity) were performed in the dark at room temperature (22±2 deg. C). In seawater T90 was; S. aure- us>FS>Salmonella spp.>FC. Survival in brackish water generally appeared to be higher than in seawater; in particular this increased from 48 to 72 h, from 88 to 104 h and from 56 to 80 h, respectively for FC, FS and Salmonella spp.
