The Association between Resistance and Virulence of Klebsiella pneumoniae in High-Risk Clonal Lineages ST86 and ST101

Microorganisms
Klebsiella pneumoniae is an opportunistic pathogen known for two main pathotypes: classical K. pneumoniae (cKp), often multidrug-resistant and common in hospitals, and hypervirulent K.

Virus‐Induced Gene Silencing in Calendula officinalis (Pot Marigold)

Plant Direct, Volume 10, Issue 5, May 2026.
ABSTRACT Virus‐induced gene silencing (VIGS) is a method that exploits plant antiviral defense mechanisms to downregulate endogenous genes. The technique is versatile, rapid, and widely used for functional genomics studies. Here, we report a method for VIGS in the medicinal plant, Calendula officinalis (pot marigold).

Emergence and Genomic Characterization of a Hypervirulent Klebsiella pneumoniae Isolate From a New Clone in Brazil

Microbiology and Immunology, Volume 70, Issue 5, Page 261-267, May 2026.
ABSTRACT Hypervirulent Klebsiella pneumoniae (hvKp) has emerged globally as a major public health concern, often associated with severe community‐acquired and healthcare‐associated human infections. Despite alerts from PAHO/WHO on convergent hvKp strains with multidrug resistance in Latin America, comprehensive data from Brazil, the region's largest ...

Comparative Proteomic Profiling of Clinical Klebsiella pneumoniae Strains and the Corresponding Outer Membrane Vesicles

Journal of Extracellular Biology, Volume 5, Issue 4, April 2026.
ABSTRACT Klebsiella pneumoniae (K. pneumoniae) has become a global threat due to the convergence of carbapenem resistance and hypervirulence. Outer membrane vesicles (OMVs) play important roles in bacterial pathogenicity, yet their functional coordination with strains remains unclear.

A Case Series of Hypermucoid Klebsiella pneumoniae Liver Abscess in Caucasian Americans Without Travel History: An Epidemiologic Shift?

Clinical Case Reports, Volume 14, Issue 3, March 2026.
ABSTRACT Hypervirulent Klebsiella pneumoniae (hvKp) is an emerging cause of community‐acquired pyogenic liver abscess (PLA), classically described in East and Southeast Asia. We report two cases of hvKp‐associated PLA in Caucasian women of American origin with no history of international travel, animal exposure, or Asian food consumption. Both patients

Metastatic infection of hypervirulent Klebsiella pneumoniae

IDCases
Hypervirulent Klebsiella pneumoniae(hvKp) has a unique ability to cause organ or life-threatening tissue invasive infection in multiple sites. This case highlights that classical hvKp resulted in multiple abscesses in every body site, especially in the necrotizing fasciitis and osteomyelitis.

Conjugative Transfer of Disease‐Encoding Plasmid Variants in Serratia spp. Alter Production of Enzymes and Virulence Properties

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Analysis of plasmid transconjugants relative to plasmid‐free and plasmid‐carrying Serratia spp. demonstrates erratic disease phenotypes and reduced fitness. Transconjugants also show reduced ability to degrade substrates associated with virulence, supported by transcriptomic data.

Mixed Impacts of the Mycovirus Fusarium Culmorum Phenuivirus 1 on Fusarium culmorum: Laboratory and In Planta Investigations

Plant Pathology, Volume 75, Issue 1, January/February 2026.
Fusarium culmorum phenuivirus 1 caused no changes in laboratory‐based assays and shows mild hypovirulence in a susceptible wheat cultivar under semifield conditions. It is highly transmissible both via spores and hyphal contact. ABSTRACT The mycovirus Fusarium culmorum phenuivirus 1 (FcPV1) infects the wheat pathogen Fusarium culmorum, a causal agent ...
