Current Opinion in Microbiology, 2020 For ∼30 years, two distinct groups of clinical isolates of Klebsiella pneumoniae have been recognized. Classical strains (cKp) are typically isolated from patients with some degree of immunocompromise and are not virulent in mouse models of infection whereas hypervirulent strains (hvKp) are associated with community acquired invasive infections and are

A Klebsiella variicola Plasmid Confers Hypermucoviscosity-Like Phenotype and Alters Capsule Production and Virulence [PDF]
Frontiers in Microbiology, 2020 Hypermucoviscosity (hmv) is a capsule-associated phenotype usually linked with hypervirulent Klebsiella pneumoniae strains. The key components of this phenotype are the RmpADC proteins contained in non-transmissible plasmids identified and studied in K. pneumoniae. Klebsiella variicola is closely related to K.

Genetic diversity of siderophores and hypermucoviscosity phenotype in Klebsiella pneumoniae
Microbial Pathogenesis, 2021Siderophore is a group of low molecular weight compounds with high affinity for ferric iron, facilitating bacterial iron consumption, especially when competing with the host. Genetic diversity of the siderophore-encoding loci largely contributes to the intricacy of siderophore production and regulation in K. pneumoniae.

The aim of this study is to document the isolation of a hypermucoviscosity (HMV) phenotype of Klebsiella pneumoniae from 25 cases of suppurative pneumonia and pleuritis and two cases of abscesses in California sea lions (Zalophus californianus) from the central California coast, representing the first report of this zoonotic pathogen from the marine ...

Journal of the Japanese Association for Infectious Diseases, 2011 A 70-year-old man with diabetes mellitus seen for fever, right chest pain, and right-lung field consolidation on chest X-ray was found in thoracoabdominal computed tomography (CT) to have variable-sized nodules in both lung fields and multiple low-density hepatic areas.

Due to the strong pathogenicity of hypervirulent Klebsiella pneumoniae (hvKP), its performance against disinfectants in water should be understood to protect public health and ecological environment. Unfortunately, the disinfectant tolerance of hvKP with a hypermucoviscosity (HMV) phenotype is a critical underexplored area.

Invasive Klebsiella pneumoniae with hypermucoviscosity phenotype (HMV K. pneumoniae) is an emerging human pathogen that, over the past 20 y, has resulted in a distinct clinical syndrome characterized by pyogenic liver abscesses sometimes complicated by bacteremia, meningitis, and endophthalmitis. Infections occur predominantly in Taiwan and other Asian
