Klebsiella pneumoniae-associated pathology is largely mediated by neutrophilic inflammation. In this study, we administered Klebsiella pneumoniae to experimental guinea pig groups and the ELR-CXC chemokine antagonist CXCL8(3-72), ceftazidime, and dexamethasone to different groups, respectively. After 24 h, we assessed the animal's pulmonary inflammatory levels, including gross histopathology, a...

Enterobacteria, in particular Klebsiella spp., have been implicated in the aetiopathogenesis of ankylosing spondylitis. A comprehensive examination of the faecal flora of 82 patients with ankylosing spondylitis, either primary (67), or in association with inflammatory bowel disease (4), reactive arthritis (6) or psoriatic arthritis (5), was performed and compared with that of a control populati...

The Australian Group on Antimicrobial Resistance performs regular period-prevalence studies to monitor changes in antimicrobial resistance in selected enteric Gram-negative pathogens. The 2011 survey focussed on hospital-onset infections, examining isolates from all specimens presumed to be causing disease. In 2011, 1,827 Escherichia coli, 537 Klebsiella species and 269 Enterobacter species wer...

Klebsiella ozaenae is a Gram negative bacillus. It has been described as a colonizer of oral and nasopharyngeal mucosa and is a cause of atrophic rhinitis. Klebsiella ozaenae has seldom been isolated from serious infections. However, several reports have stated that Klebsiella ozaenae may cause invasive infections and even mortality. We report a 55-year-old man with Klebsiella ozaenae infection...

Molecular typing of Klebsiella species has become important for monitoring dissemination of β-lactamase-producers in hospital environments. The present study was designed to evaluate poly-trinucleotide (GTG)(5)- and rDNA intergenic transcribed spacer (ITS)-PCR fingerprint analysis for typing of Klebsiella pneumoniae and Klebsiella oxytoca isolates. Multiple displacement amplified DNA derived fr...

The antimicrobial resistance of Klebsiella species in the poultry industry is becoming a public concern. In support our recent publication "Characterization of antimicrobial resistance in Klebsiella species isolated from chicken broilers" (Wu et al., 2016) [1], multilocus sequence typing (MLST) and gyrA PCR-RFLP assays were conducted to identify the genetic relationships between and phylogeneti...

HLA B27 is associated with a number of forms of arthritis, including ankylosing spondylitis. It has been suggested that the disease is caused by Klebsiella pneumoniae and that the bacterium evokes an odd immune response because it cross-reacts with HLA B27. This proposed cross-reactivity was investigated in a number of ways. The results consistently failed to confirm evidence from cross reactio...

background and aims: recently it has been proved that some of enterobacteriacea like klebsiella pneumoniae, which carry pks islands, damage dsdna by encoding colibactin genotoxin; and finally they induce some apoptosis in damaged mucosal cells. this study aimed to isolating the clbn and clbb genes, which are the markers of the pks genomic island, from pks cluster in these bacteria materials and...
