Journal of Microbiology, Immunology and Infection, 2020 Background: Zoonotic Salmonella enterica serovar Choleraesuis (S. Choleraesuis), causing paratyphoid in pigs and bacteremia in humans, commonly carry a virulence plasmid and sometimes a separate antimicrobial-resistant plasmid or merging together.

Virulence-associated plasmids in Rhodococcus equi [PDF]
Journal of Clinical Microbiology, 1993 Twenty-three strains of Rhodococcus equi from independent clinical cases were analyzed for the presence of virulence plasmid DNA. Of the clinical isolates, 19 contained an 85-kb plasmid and the remaining 4 contained a 90-kb plasmid. All of the isolates expressed 15- to 17-kDa antigens and were virulent in mice.

Plasmid-associated virulence of Salmonella typhimurium [PDF]
Infection and Immunity, 1987 We investigated the role of the 100-kilobase (kb) plasmid of Salmonella typhimurium in the virulence of this organism for mice. Three strains, LT2-Z, SR-11, and SL1344, which possessed 100-kb plasmids with identical restriction enzyme digestion profiles, were cured of their respective 100-kb plasmids after Tnmini-tet was used to label plasmids.

The Multifaceted Activity of the VirF Regulatory Protein in the Shigella Lifestyle [PDF]
, 2016 Shigella is a highly adapted human pathogen, mainly found in the developing world and causing a severe enteric syndrome. The highly sophisticated infectious strategy of Shigella banks on the capacity to invade the intestinal epithelial barrier and cause ...

The Salmonella typhimurium virulence plasmid encodes a positive regulator of a plasmid-encoded virulence gene [PDF]
Journal of Bacteriology, 1991 The 90-kb virulence plasmid of Salmonella typhimurium is necessary for invasion beyond the Peyer's patches to the mesenteric lymph nodes and spleens of orally inoculated mice. Two Tn5 insertions located on the left side of a previously identified 14-kb virulence region (P. A. Gulig and R. Curtiss III, Infect. Immun.

Virulence Plasmids of Spore-Forming Bacteria
Microbiology Spectrum, 2014 ABSTRACT Plasmid-encoded virulence factors are important in the pathogenesis of diseases caused by spore-forming bacteria. Unlike many other bacteria, the most common virulence factors encoded by plasmids in Clostridium and Bacillus species are protein toxins ...

Characterization of an emergent clone of enteroinvasive Escherichia coli circulating in Europe [PDF]
, 2016 Enteroinvasive Escherichia coli (EIEC) cause intestinal illness indistinguishable from that caused by Shigella, mainly in developing countries. Recently an upsurge of cases of EIEC infections has been observed in Europe, with two large outbreaks ...

Journal of Global Antimicrobial Resistance, 2020 Objective: We investigated the pathogenesis of a patient with severe acute pancreatitis by comprehensively analysing a rare carbapenem-resistant hypervirulent K1/ST1265 Klebsiella pneumoniae (CR-HvKP) strain. Methods: We conducted virulence and multidrug-
