The emergence of ‘hypervirulence’ in Clostridium difficile
International Journal of Medical Microbiology, 2010 The impact of Clostridium difficile-associated disease (CDAD) in healthcare settings throughout the developed world is considerable in terms of mortality, morbidity, and disease management. The incidence of CDAD has risen dramatically since the turn of this century, concomitant with the emergence of so-called hypervirulent strains which are thought to ...

Klebsiella species: Taxonomy, hypervirulence and multidrug resistance
EBioMedicine, 2022 Members of the genus Klebsiella have rapidly evolved within the past decade, generating organisms that simultaneously exhibit both multidrug resistance and hypervirulence (MDR-hv) phenotypes; such organisms are associated with severe hospital- and community-acquired infections.

Hypervirulence and pathogen fitness
Trends in Microbiology, 2003Historically, pathogenesis research has focused on the identification and characterization of virulence factors. More recently, 'anti-virulence' genes have been discovered. Mutations in these loci result in a hypervirulent phenotype, as measured by a lower lethal dose, a colonization advantage, reduced clearance or decreased survival time of the host ...

Presence of hypervirulence-associated determinants in Klebsiella pneumoniae from hospitalised patients in Germany [PDF]
International Journal of Medical MicrobiologyBackground: Klebsiella (K.) pneumoniae is a ubiquitous Gram-negative bacterium and a common coloniser of animals and humans. Today, K. pneumoniae is one of the most persistent nosocomial pathogens worldwide and poses a severe threat/burden to public ...

Hypervirulent Klebsiella pneumoniae detection methods: a minireview
Archives of Microbiology, 2023Hypervirulent Klebsiella pneumoniae (hvKp), characterized by high virulence and epidemic potential, has become a global public health challenge. Therefore, improving the identification of hvKp and enabling earlier and faster detection in the community to support subsequent effective treatment and prevention of hvKp are an urgent issue. To address these

Biodiversity and hypervirulence of Listeria monocytogenes
Nature Genetics, 2016The integration of large, well-sampled collections of bacterial isolates with genomics and experimental methods provides opportunities for 'top-down' discovery of the genetic basis of phenotypes of interest. In a new report, the authors apply this approach to investigate the heterogeneity in manifestations of disease caused by Listeria monocytogenes ...

Getting hypervirulent Klebsiella pneumoniae on the radar screen
Current Opinion in Infectious Diseases, 2018Purpose of review Two pathotypes of Klebsiella pneumoniae cause human infections, classical (cKp) and hypervirulent (hvKp) K. pneumoniae. The present understanding of genetic elements, the need for an accurate test to identify hvKp, the clinical implications of infection, the knowledge gap on how and why hvKp colonization ...

Hypervirulent Klebsiella Pneumoniae Osteomyelitis in a Child
Pediatric Infectious Disease JournalAn 18-month-old boy presented with septic arthritis and osteomyelitis caused by Hypervirulent Klebsiella pneumoniae harboring cardinal virulence genes. The condition necessitated several surgical interventions, and a prolonged course of antibiotic therapy to effectively manage the severe infection and prevent complications, highlighting the challenges ...
