The Genome Sequence of Avian Pathogenic Escherichia coli Strain O1:K1:H7 Shares Strong Similarities with Human (2006)

Extraintestinal Pathogenic, E. Genomes, Timothy J. Johnson, Subhashinie Kariyawasam, Yvonne Wannemuehler, Paul Mangiamele, ...

Escherichia coli strains that cause disease outside the intestine are known as extraintestinal pathogenic E. coli (ExPEC) and include human uropathogenic E. coli (UPEC) and avian pathogenic E. coli...

DNA Sequence and Comparative Genomics of pAPEC-O2-R, an Avian Pathogenic Escherichia coli Transmissible R Plasmid

Johnson, Timothy J., Siek, Kylie E., Johnson, Sara J., Nolan, Lisa K.

In this study, a 101-kb IncF plasmid from an avian pathogenic Escherichia coli (APEC) strain (APEC O2) was sequenced and analyzed, providing the first completed APEC plasmid sequence. This plasmid,...

DNA Sequence of a ColV Plasmid and Prevalence of Selected Plasmid-Encoded Virulence Genes among Avian Escherichia coli Strains

Johnson, Timothy J., Siek, Kylie E., Johnson, Sara J., Nolan, Lisa K.

ColV plasmids have long been associated with the virulence of Escherichia coli, despite the fact that their namesake trait, ColV production, does not appear to contribute to virulence. Such plasmids...

Complete DNA Sequence of a ColBM Plasmid from Avian Pathogenic Escherichia coli Suggests that It Evolved from Closely Related ColV Virulence Plasmids†

Johnson, Timothy J., Johnson, Sara J., Nolan, Lisa K.

Avian pathogenic Escherichia coli (APEC), an extraintestinal pathogenic E. coli causing colibacillosis in birds, is responsible for significant economic losses for the poultry industry. Recently, we...

Johnson, Timothy J., Wannemeuhler, Yvonne M., Scaccianoce, Jennifer A., Johnson, Sara J., Nolan, Lisa K.

We have sequenced a large plasmid that occurs among avian pathogenic Escherichia coli isolates. This plasmid, pAPEC-O1-R, is a 241,387-bp IncHI2 plasmid which is cotransmissible via bacterial...

Plasmid Replicon Typing of Commensal and Pathogenic Escherichia coli Isolates▿

Johnson, Timothy J., Wannemuehler, Yvonne M., Johnson, Sara J., Logue, Catherine M., White, David G., Doetkott, Curt, ...

Despite the critical role of plasmids in horizontal gene transfer, few studies have characterized plasmid relatedness among different bacterial populations. Recently, a multiplex PCR replicon typing...
