Project description:Hypervirulent Klebsiella pneumoniae (hvKp) causes invasive infections and severe systemic inflammation. In this study, outer membrane vesicles (OMVs) derived from clinically isolated hvKp and classical K. pneumoniae (cKp) strains were characterized using an integrated proteogenomic workflow combining whole-genome sequencing and label-free LC–MS/MS proteomics. The dataset includes quantitative proteomic profiles of OMVs and whole-cell lysates together with strain-specific protein annotations for comparative analyses of OMVs cargo composition, functional annotation, and pathogenicity.
Project description:Streptococcus (S.) pneumoniae is the most frequently isolated causative pathogen community-acquired pneumonia, a leading cause of mortality worldwide. We investigated the role of the inflammasome sensor NLRP3 and the inflammasome adapter ASC during S. pneumoniae pneumonia. Detailed analysis of the early inflammatory response in the lung by whole genome transcriptional profiling, we identified several mediators that were differentially expressed between Nlrp3-/- and Asc-/ - mice.
Project description:Klebsiella pneumoniae is a gram-negative bacterium that can cause lung disease in humans. Meanwhile, the contamination situation of Klebsiella pneumoniae in aquaculture environment is critical. In this study, we determined for the first time the growth of Klebsiella pneumoniae isolated from common edible aquatic products in different carbon sources.
