Bronchoscopic Direct Drainage of a Treatment‐Resistant Lung Abscess via Endoscopic Balloon Dilation in a High‐Risk Patient

Respirology Case Reports, Volume 14, Issue 5, May 2026.
Bronchoscopic direct drainage after balloon dilation can be a viable treatment option for patients with a severe, treatment‐resistant lung abscess who have comorbidities and are not eligible for percutaneous transthoracic drainage or surgery. ABSTRACT A 49‐year‐old man presented with a cough, hemoptysis and fever.

Co-occurrence of ST412 Klebsiella pneumoniae isolates with hypermucoviscous and non-mucoviscous phenotypes in a short-term hospitalized patient

mSystems
Hypermucoviscosity (HMV) is a phenotype that is commonly associated with hypervirulence in Klebsiella pneumoniae. The factors that contribute to the emergence of HMV subpopulations remain unclear. In this study, eight K. pneumoniae strains were recovered

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 ...

Correlation between Phenotypic Hypermucoviscosity and Antibiotic Resistance in Klebsiella pneumoniae

The Journal of Medical Research
Abstract Introduction: Klebsiella pneumoniae is a Gram-negative opportunistic pathogen increasingly associated with multidrug resistant (MDR) and hypervirulence. The hypermucoviscous (HMV) phenotype, detected via the string test, is a surrogate marker for hypervirulent strains.

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

Clinical Epidemiological Analysis of the Genotypic Spectrum and Mortality Risk in Carbapenem‐Resistant Klebsiella pneumoniae (CRKP) Infections

Canadian Journal of Infectious Diseases and Medical Microbiology, Volume 2026, Issue 1, 2026.
Background Carbapenem‐resistant Klebsiella pneumoniae (CRKP) has become a global public health threat, with significantly increased morbidity and mortality among high‐risk inpatients. High‐risk genotypes of CRKP, primarily including K. pneumoniae carbapenemase (KPC), oxacillinase‐48–like (OXA‐48–like), New Delhi metallo‐β‐lactamase (NDM), imipenemase ...
