Relation between Aeromonas and faecal coliforms in fresh waters.
A possible correlation between the presence of mesophilic aeromonads and the number of faecal coliforms present in three fresh-water habitats subject to differing levels of faecal pollution was investigated. Concentration of Aeromonas spp. between 10(2)-10(9) cfu/100 ml and faecal coliforms of between 9-10(7) cfu/100 ml were found in the waters. In water free from faecal pollution there was no correlation but in polluted waters there was a significant relationship between the numbers of aeromonads, faecal coliform and the concentration of organic matter measured by biological oxygen demand.
