Within-host evolution of *S.* Typhimurium may lead to pathovars adapted to specific hosts.
Enterohemorrhagic *Escherichia coli* (EHEC) strains, including the foodborne pathogen *E. coli* O157:H7, are responsible for thousands of hospitalizations each year. Various environmental triggers can modulate pathogenicity in EHEC by inducing the …
Enterohemorrhagic Escherichia coli (EHEC) strains, including E. coli O157:H7, cause severe illness in humans due to the production of Shiga toxin (Stx) and other virulence factors. Because Stx is coregulated with lambdoid prophage induction, its …
Twenty-seven Salmonella isolates were collected from four locations within an ecological wastewater treatment system located at The Pennsylvania State University and were subjected to whole-genome sequencing. The sequences obtained were used for in …
Most Group I Clostridium botulinum strains harbor botulinum neurotoxin (bont) genes on their chromosome, while some carry these genes (including bont/a, bont/b, and bont/f) on large plasmids. Prior work in our laboratory demonstrated that Group I …
Botulinum neurotoxins (BoNTs), produced by anaerobic bacteria, are the cause of the potentially deadly, neuroparalytic disease botulism. BoNTs have been classified into seven serotypes, serotypes A to G, based upon their selective neutralization by …
Resveratrol, a polyphenolic phytoalexin, is produced by plants in response to infection and has antibacterial activity. *Haemophilus ducreyi* is a Gram-negative bacterium that is the causative agent of the sexually transmitted disease chancroid. This …
