Abstract
The present invention discloses a mutant Neisseria having extensive membrane blebbing, both an indicium and a cause of virulence in the gonococcus and meningococcus. Methods are disclosed for making and characterizing the mutant, bmrRS. Methods are disclosed for isolating bmrRS membranes for use as a vaccine. Methods are also disclosed for the use of the mutant for determining the virulence of clinical samples of N. gonorrhoeae and N. meningitidis. Methods are also disclosed for the screening of antibiotics targeted to virulent Neisseria.
Claims5
A Neisseria bacterium comprising a mutant two-component regulatory (2CR) system that controls super-blebbing, wherein said system comprises DNA encoding a BmrR open reading frame (ORF) and a BmrS ORF, wherein the BmrR ORF or the BmrS ORF contains an insertion or a deletion as compared to corresponding wild-type BmrR ORF or BmrS ORF.
