Population-Based Surveillance for Hypermucoviscosity Klebsiella pneumoniae Causing Community-Acquired Bacteremia in Calgary, Alberta

Canadian Journal of Infectious Diseases and Medical Microbiology, 2013
The characteristics of hypermucoviscosity isolates among Klebsiella pneumoniae causing community-acquired bacteremia were investigated. The hypermucoviscous phenotype was present in 8.2% of K pneumoniae isolates, and was associated with rmpA and the K2 ...

Gross necropsy lesions and clinical presentations in New Zealand sea lion pups consistent with causes of mortality other than hypermucoviscous K. pneumoniae infection.

, 2019
(A) Hyperinflation of the lungs in a case of drowning, note the lung lobes overlapping and obscuring the heart. (B) A subadult male harasses a pup, a situation that can result in crushing and asphyxiation of the pup.

Primary liver abscess due to CC23-K1 virulent clone of Klebsiella pneumoniae in France

, 2012
Since the mid-1980s, Klebsiella pneumoniae hypermucoviscous isolates have emerged in Taiwan and other Asian countries. We reported the first autochthonous European liver abscess due to an ST57 isolate, which belongs to virulent clonal complex CC23-KI ...

The New Klebsiella pneumoniae ST152 Variants with Hypermucoviscous Phenotype Isolated from Renal Transplant Recipients with Asymptomatic Bacteriuria—Genetic Characteristics by WGS

, 2020
Klebsiella pneumoniae (Kp) is one of the most important etiological factors of urinary tract infections in renal transplant (RTx) recipients. We described the antimicrobial susceptibility phenotypes and genomic features of two hypermucoviscous (HM) Kp ...

Comparative genetic analysis of the antimicrobial susceptibilities and virulence of hypermucoviscous and non-hypermucoviscous ESBL-producing Klebsiella pneumoniae in Japan

Comparative genetic analysis of the antimicrobial susceptibilities and virulence of hypermucoviscous and non-hypermucoviscous ESBL-producing Klebsiella pneumoniae in Japan
Background: Hypermucoviscous (HMV) Klebsiella pneumoniae produces large amounts of capsular polysaccharides, leading to high mortality. Since extended spectrum beta-lactamase (ESBL)-producing HMV K. pneumoniae strains have increased in Japan, we investigated and compared the antimicrobial susceptibilities and genetic characteristics of HMV and non-HMV ...

Pyogenic liver abscess caused by an atypical hypervirulent Klebsiella pneumoniae K1-ST23 in Mexico

IDCases
Hypervirulent K. pneumoniae infection has been raising worldwide and is one of the major causes of community-acquired pyogenic liver abscess. We described a case report of pyogenic liver abscess caused by an atypical hypervirulent (non-hypermucoviscous ...

Insights into the recognition of hypermucoviscous Klebsiella pneumoniae clinical isolates by innate immune lectins of the Siglec and galectin families [PDF]

Klebsiella pneumoniae is an opportunistic bacterium that frequently colonizes the nasopharynx and gastrointestinal tract and can also cause severe infections when invading other tissues, particularly in immunocompromised individuals.
