The putative functions of lysogeny in mediating the survivorship of Escherichia coli in seawater and marine sediment.

Escherichia coli colonizes various body parts of animal hosts as a commensal and a pathogen. It can also persist in the external environment in the absence of fecal pollution. It remains unclear how this species has evolved to adapt to such contrasting habitats.

Draft Genome Sequences of Three Escherichia coli Strains Investigated for the Effects of Lysogeny on Niche Diversification.

During the course of investigating the effects of lysogeny on niche diversification of Escherichia coli, we used the temperate phages induced from one E. coli strain to infect another and created an isogenic lysogen of the latter. The draft genome sequences of the three E.

Draft Genome Sequence of Escherichia coli E1728 Isolated from Marine Sediment in Hong Kong.

Recent findings of Escherichia coli persisting autochthonously in environmental matrices outside animal bodies have revealed largely unknown facets of the lifestyle and ecophysiology of the species that have yet to be explored. Here, we report the draft genome sequence of E. coli E1728 isolated from marine sediment.

Host-specific 16S rRNA gene markers of Bacteroidales for source tracking of fecal pollution in the subtropical coastal seawater of Hong Kong.

This study investigated the diversity of Bacteroidales communities in the feces of eight host species in Hong Kong (subtropical Asia), including human (in the form of sewage), cow, pig, horse, cat, dog, rabbit and rat. The analysis of terminal restriction fragment length polymorphism (TRFLP) in the 16S rRNA genes revealed significant differences in Bacteroidales communities among all host species, with the exception of dog and cat. Manual examination of TRFLP profiles resulted in six terminal restriction fragments (TRFs) that were potentially specific to the sewage (one TRF), cow (three TRFs) or pig (two TRFs) samples.
