VIRULENCE GENE REGULATION INSIDE AND OUTSIDE

The Activities of Bacterial Pathogens In Vivo, 2000
Much knowledge about microbial gene regulation and virulence is derived from genetic and biochemical studies done outside of hosts. The aim of this review is to correlate observations made in vitro and in vivo with two different bacterial pathogens in which the nature of regulated gene ...

Hybrid Resistance and Virulence Plasmids in “High-Risk” Clones of Klebsiella pneumoniae, Including Those Carrying bla_NDM-5

Microorganisms, 2019
Virulence plasmids are associated with hypervirulent types of Klebsiella pneumoniae, which generally do not carry antibiotic resistance genes. In contrast, nosocomial isolates are often associated with resistance, but rarely with virulence plasmids. Here,

Genotypic virulence profiles and associations in Salmonella isolated from meat samples in wet markets and abattoirs of Metro Manila, Philippines

BMC Microbiology, 2022
Background Salmonella are pathogenic foodborne bacteria with complex pathogenicity from numerous virulence genes housed in Salmonella pathogenicity islands (SPIs), plasmids, and other gene cassettes.

Epigenetic memory at malaria virulence genes [PDF]

Proceedings of the National Academy of Sciences, 2007
During its red blood cell stage, the malaria parasite Plasmodium falciparum can switch its variant surface proteins ( P. falciparum erythrocyte membrane protein 1) to evade the host immune response.

The Viral Replication Complex Is Associated with the Virulence of Newcastle Disease Virus [PDF]

, 2010
Virulent strains of Newcastle disease virus ([NDV] also known as avian paramyxovirus type 1) can be discriminated from low-virulence strains by the presence of multiple basic amino acid residues at the proteolytic cleavage site of the fusion (F) protein.

Pseudomonas virulence factor controls expression of virulence genes in Pseudomonas entomophila

PLOS ONE, 2023
Quorum sensing is a communication strategy that bacteria use to collectively alter gene expression in response to cell density. Pathogens use quorum sensing systems to control activities vital to infection, such as the production of virulence factors and biofilm formation.

Novel insights into the epigenetic regulation of Plasmodium falciparum virulence genes [PDF]

, 2013
Plasmodium falciparum malaria still places a major health burden upon the developing world. The high virulence of this parasite is linked to the variegated expression of single P.

Coexistence of virulence genes in methicillin-resistant Staphylococcus aureus clinical isolates

Revista da Sociedade Brasileira de Medicina Tropical
INTRODUCTION: The pathogenic versatility of Staphylococcus aureus is attributed to various virulence genes, including enterotoxins and hemolysins. METHODS: Here, the virulence genes in 177 nosocomial MRSA strains in Porto Alegre, Brazil were detected ...

Phylogenomic analysis of natural selection pressure in Streptococcus genomes [PDF]

, 2007
In comparative analyses of bacterial pathogens, it has been common practice to discriminate between two types of genes: (i) those shared by pathogens and their non-pathogenic relatives (core genes), and (ii) those found exclusively in pathogens (pathogen-
