?DNA fingerprint analyses indicated that some E. coli strains may be naturalized, and
autochthonous members of the microbial community in the beach sand and sediments
were examined. However, multiplex PCR results indicated that <1% of the
E. coli strains at the DBC was
potentially pathogenic? How is the potential pathogenicity of e coli surviving
in sediments determined? I was not aware you could test sediment dwelling
bacteria for pathogenicity. Some of the literature says that virulence is an advantage for microbes surviving in secondary environments, other papers say that since the gene for virulence takes extra energy, it?s a disadvantage for survival. Looking forward to the day when we know whether bacteria coming out of a sewage outfall are more pathogenic than the subset bacterial species that have adapted to sediment survival. Thanks for this forum its very good.
Thanks
