Hypervirulent Klebsiella pneumoniae [PDF]
Open Forum Infectious Diseases, 2014 Abstract Hypervirulent strains of Klebsiella pneumoniae are associated with abscess formation, commonly hepatic, and metastatic spread, even in healthy patients. We describe a case of this clinical syndrome, genotypic and phenotypic features of the isolate, and briefly review epidemiology, clinical manifestations, and pathogenesis of ...

Pathogenesis of Hypervirulent Group A Streptococcus [PDF]
Japan Journal of Medicine, 2018 Group A Streptococcus (GAS) causes common pharyngitis and skin infections and occasional severe invasive infections. This review describes the recent progress on the pathogenesis of hypervirulent GAS. CovRS mutations are frequent among invasive GAS isolates and lead to hypervirulence. GAS CovRS mutants can be selected in vivo by neutrophils.

The making of hypervirulent Klebsiella pneumoniae
Journal of Clinical Laboratory Analysis, 2022 AbstractKlebsiella pneumoniae is a notorious bacterium in clinical practice. Virulence, carbapenem‐resistance and their convergence among K. pneumoniae are extensively discussed in this article. Hypervirulent K. pneumoniae (HvKP) has spread from the Asian Pacific Rim to the world, inducing various invasive infections, such as pyogenic liver abscess ...

The case for hypervirulence through gene deletion in Mycobacterium tuberculosis.
, 2008 Deletion of genes in a pathogen is commonly associated with a reduction in its ability to cause disease. However, some rare cases have been described in the literature whereby deletion of a gene results in an increase in virulence.
