  1. Seasonal occurrence of mesophilic Aeromonas spp. as a function of biotype and water quality in temperate freshwater lakes.

    Article - En anglais

    Densities of mesophilic aeromonads were compared in Virginia freshwater lakes with trophic classifications ranging from mesotrophic to hypereutrophic.

    Aeromonad concentrations were independent of trophic status and did not correlate statistically with water quality parameters used to measure trophic state (total phosphorus, chlorophyll a and Secchi depth).

    Bacterial indicators (fecal coliforms and Escherichia coli) used to assess the public health safety of recreational waters correlated with mesophilic aeromonads only when sewage pollution occurred.

    Overall (n=101-107) there were small negative correlations of aeromonad densities with dissolved oxygen (r=-0.30, P=<0.05), and total dissolved nitrogen (r=-0.30, P=0.05).
