Virulence plasmid-associated autoagglutination in Yersinia spp [PDF]

Journal of Bacteriology, 1984
The autoagglutination of Yersinia enterocolitica was dependent on the presence of the virulence plasmid and on the active growth of bacteria in tissue culture media at 37 degrees C. Cultures with a high initial concentration of bacteria failed to autoagglutinate , indicating that synthesis of new virulence plasmid-associated surface factors was ...

Genomic and functional characterization of a blaNDM-1 and tmexCD2-toprJ2 co-producing Klebsiella quasipneumoniae (KL159/ST1929) reveals plasmid-mediated suppression of virulence [PDF]

Microbiology Spectrum
Klebsiella quasipneumoniae has emerged as a multidrug-resistant (MDR) pathogen of growing clinical concern, driven by its capacity to acquire mobile genetic elements encoding carbapenemases and novel resistance determinants.

Shiga toxin-producing Escherichia coli plasmid diversity reveals virulence potential and control opportunities in animal hosts [PDF]

Scientific Reports
Shiga toxin-producing Escherichia coli (STEC) is a significant public health concern, with plasmids playing a key role in its pathogenicity. This study investigates the relationship between plasmid types, virulence genes, and host specificity in 96 STEC ...

A Siderophore-Encoding Plasmid Encodes High-Level Virulence in Escherichia coli

Microbiology Spectrum, 2022
A plasmid that harbored the virulence factors highly like those of the virulence plasmid commonly found in clinical hypervirulent Klebsiella pneumoniae strains was detected in a foodborne Escherichia coli strain EC1108 and designated p1108-IncFIB.

Does virulence assessment of Vibrio anguillarum using sea bass (Dicentrarchus labrax) larvae correspond with genotypic and phenotypic characterization? [PDF]

, 2013
Background: Vibriosis is one of the most ubiquitous fish diseases caused by bacteria belonging to the genus Vibrio such as Vibrio (Listonella) anguillarum. Despite a lot of research efforts, the virulence factors and mechanism of V. anguillarum are still

Transmission of Nonconjugative Virulence or Resistance Plasmids Mediated by a Self-Transferable IncN3 Plasmid from Carbapenem-Resistant Klebsiella pneumoniae

Microbiology Spectrum, 2022
Klebsiella pneumoniae poses a critical challenge to clinical and public health. Along with conjugative plasmids, nonconjugative resistance or virulence plasmids associated with carbapenem-resistant K. pneumoniae (CRKP), hypervirulent K. pneumoniae (hvKP),

Distribution of Virulence Plasmids within Salmonellae [PDF]

Microbiology, 1989
The virulence region of the Salmonella dublin 50 MDa plasmid shared homology with 678 of 1021 salmonellae tested in colony hybridization experiments. The majority of S. dublin, S. typhimurium and S. enteritidis isolates tested hybridized with the region whereas, with the exception of S. hessarek, S. pullorum and S.
