Project description:The increasing antibiotic resistance of Klebsiella pneumoniae poses a serious threat to global public health. To investigate the antibiotic resistance mechanism of Klebsiella pneumonia, we performed gene expression profiling analysis using RNA-seq data for clinical isolates of Klebsiella pneumonia, KPN16 and ATCC13883. Our results showed that mutant strain KPN16 is likely to act against the antibiotics through increased increased butanoate metabolism and lipopolysaccharide biosynthesis, and decreased transmembrane transport activity.
Project description:Klebsiella pneumoniae poses significant threat to global health. Detailed investigation to the nature of its interaction to human epithelial cells is still lacking. OmpR is an important regulator to the expression of major outer membrane protein genes, ompF and ompC. Here, we exploited the recently described dual RNA-seq to simultaneously measure genome-wide expression of host and pathogen two hours into infection. By comparing OmpR deleted strain to its wildtype parental strain, we, simultaneously, reconstructed OmpR regulon and deletion effect to host response.
