Carbapenemases of Chryseobacterium Flavobacterium meningosepticum: When these carbapenem non-susceptible strains are found, they may be submitted to phenotypic M b L detection test in the microbiology laboratory in order to help infection control practioners and prevent the M b L gene dissemination, once these genes are embedded in mobile genetic elements, which can spread rapidly to other Gram-negative species.


Site-specific deletion and rearrangement of integron insert genes catalyzed by the integron DNA integrase. Site-specific insertion of gene cassettes into integrons. Most of these isolates had 8 out of the 9 analysed virulence factors.
