Antimicrobial susceptibilities of Aeromonas spp. isolated from environmental sources

Article Abstract:

A study isolated a total of 282 Aeromonas pure cultures from both urban and rural playa lakes in the vicinity of Lubbock, Texas, and several rivers in West Texas and New Mexico. The highest levels of antibiotic resistance detected in Aeromonas spp. from polluted water environments point to the existence of a threshold level of heavy metals necessary to select for populations of Aeromonas isolates that contain multiple resistance plasmids.

Survival of mycobacterium avium, Legionella pneumophila, Escherichia coli, and Caliciviruses in drinking water-associated biofilms grown under high-shear turbulent flow

Article Abstract:

The studies of the survival of Mycobacterium avium, Legionella pneumophila, Escherichia coli, and canine calicivirus (CaCV) by employing propella biofilm showed that pathogenic bacteria entering water distribution systems could survive in biofilms for at least several weeks, even under conditions of high-shear turbulent flow.

Ubiquity and persistence of Escherichia coli in a midwestern coastal stream

Article Abstract:

Research has been conducted on Escherichia coli in a coastal stream of Lake Michigan. The authors have investigated the sources of elevated E. coli levels in the stream, and they have concluded that the ditching of the stream, increased drainage and loss of wetlands may be the cause of chronically high E. coli levels.
