Multidrug-Resistant and Hypervirulent Klebsiella pneumoniae from Invasive Clinical Samples: Evidence from a Tertiary-Care Hospital in India

Microbiology Research
The rise in multidrug resistance in Klebsiella pneumoniae is an alarming issue, especially in invasive infections among patients with co-morbidities. With the gain of hypervirulence traits, multidrug-resistant K.

Monocyte inflammation and adaptive immune dysfunction in severe Klebsiella pneumoniae pneumonia

iMeta, EarlyView.
Severe Klebsiella pneumoniae pneumonia combines intense inflammation with failure to control infection, yet the cellular basis is unclear. Using a severity‐focused single‐cell atlas of 708,894 peripheral blood mononuclear cells from 100 individuals, complemented by plasma protein measurements and flow cytometry, we show that disease severity redirects ...

Mycobacterium intracellulare M.i.198—A Promising Strain for Studying Pathogenesis of Nontuberculous Mycobacterial Pulmonary Disease (NTM‐PD)

Microbiology and Immunology, EarlyView.
ABSTRACT In this review, we introduce a promising strain for studying pathogenesis of nontuberculous mycobacterial pulmonary disease (NTM‐PD), Mycobacterium intracellulare M.i.198. M.i.198 was isolated from a patient with progressive Mycobacterium avium‐intracellulare complex pulmonary disease (MAC‐PD) in whom surgical operation was required to ...

Hypervirulent strains of Clostridium difficile [PDF]

Postgraduate Medical Journal, 2007
Abstract North America has seen increasing numbers of hospitalised patients and others in nursing homes and the community, with more severe Clostridium difficile associated diarrhoea. This is also described in Northern Europe and surveillance systems are being developed or improved to monitor the situation.

Emergence of KPC-2 and NDM-13-coproducing carbapenem-resistant hypervirulent Klebsiella pneumoniae with high-risk sequence type ST11

Frontiers in Microbiology
BackgroundCarbapenem-resistant hypervirulent Klebsiella pneumoniae (CR-hvKp) co-producing KPC and NDM poses serious threats to public health. This study aimed to elucidate the molecular mechanisms underlying the resistance and virulence of a clinical CR ...

Molecular Diagnostics for WHO Priority Bacterial Pathogens: A Bibliometric Mapping of Diagnostic Platforms, Resistance Markers, and Antimicrobial Resistance Research Trends

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
This bibliometric mapping of 1746 publications (2000–2025) charts molecular diagnostics for WHO priority bacterial pathogens across platforms, targets, and resistance markers. Conventional PCR/NAAT and whole‐genome sequencing emerge as complementary core platforms, and the field evolves from targeted pathogen detection into an AMR‐centered ...

Sputum Gram stain of hypervirulent Klebsiella pneumoniae

Journal of General and Family Medicine, 2023
Hypervirulent Klebsiella pneumoniae has virulence genes relevant to capsule overproduction, which could lead to the finding of thick transparent area ("halo") in Gram stain. In sputum Gram stain, observation of a large Gram-negative rod with a thick capsule may not only indicate that it is K. pneumoniae but also that it is a highly virulent strain.
