Klebsiella (K.) pneumoniae is a common cause of pneumonia-derived sepsis. Myeloid related protein 8 (MRP8, S100A8) and MRP14 (S100A9) are the most abundant cytoplasmic proteins in neutrophils. They can form MRP8/14 heterodimers that are released upon cell stress stimuli. MRP8/14 reportedly exerts antimicrobial activity, but in acute fulminant sepsis models MRP8/14 has been found to contribute t...

Klebsiella pneumoniae is a common cause of nosocomial pneumonia. Osteopontin (OPN) is a phosphorylated glycoprotein involved in inflammatory processes, some of which is mediated by CD44. The aim of this study was to determine the role of OPN during K. pneumoniae-induced pneumonia. Wild-type (WT) and OPN knockout (KO) mice were intranasally infected with 10⁴ colony forming units of K. pneumoniae...

AIM To isolate and characterize bacteriophage lytic for the opportunistic pathogen Klebsiella oxytoca and their formulation into a range of solid dosage forms for in-vitro testing. METHODS AND RESULTS We report the isolation, genomic and functional characterization of a novel bacteriophage lytic for Klebsiella oxytoca, which does not infect the closely related Klebsiella pneumoniae. This bact...

Klebsiella pneumoniae is ubiquitous in the environment and is a member of a three-species biofilm model. We compared the genome sequence of an environmental isolate, K. pneumoniae strain KP-1, to those of two clinical strains (NTUH-K2044 and MGH 78578). KP-1 possesses strain-specific prophage sequences that distinguish it from the clinical strains.

Klebsiella sp. cause a wide range of human infections, particularly nosocomial septicaemia, pneumonia and urinary tract infections. Like other Enterobacteriaceae, Klebsiella are likely to possess plastic genomes comprised of core regions interspersed with horizontally acquired genomic islands. As phenylalanine tRNA genes are known to be occupied by islands in other Enterobacteriaceae, we utiliz...

We present the draft genome of highly drug-resistant Klebsiella pneumoniae KGM-IMP216, isolated from a urine sample collected from a patient in Lebanon. The draft genome sequence consisted of 77 contigs, including a combined 5,731,500 bases with 57% G+C content.

Ankylosing spondylitis (AS) is a potentially disabling rheumatic disease for which no curative treatment has yet been discovered. An extensive computer-based and manual search was undertaken to evaluate the role of microbes in the pathogenesis of AS. All together 147 papers were scrutinised. A total of 24 studies carried out on 1330 AS patients and 1191 healthy controls involving 15 different c...

Urinary tract infections (UTIs) are among the most commonly encountered infections, both in the community and in hospitals. The study investigated the Prevalence of Klebsiella species among patients suspected of UTI in Murtala Muhammad Specialist Hospital, Kano, Nigeria. Two hundred urine specimens of patients comparing of 135(67.5%) outpatients and 65(32.5%) inpatients and classified into 125(...

OBJECTIVES Pyogenic liver abscess (PLA) is a significant, though uncommon, cause of morbidity in the United States. Recently, Klebsiella has emerged as an important cause of PLA. We analyzed the clinical course, microbiology, and treatment outcomes of patients discharged with PLA. In addition, we sought to examine the incidence of and risk factors for Klebsiella liver abscess (KLA). METHODS W...

INTRODUCTION Increase in extended-spectrum β-lactamases (ESBL) producing microbes in recent years has led to limitations of treatment options. This study aimed to assess the prevalence of ESBL producing E. coli and Klebsiella spp. at a tertiary hospital in Nepal. METHODS A total of 2209 non-repetitive mid-stream urine (MSU) samples were collected during the study period (March to September 20...
