Using a real-time PCR assay specific for a mosaic penA allele that has been associated with oral cephalosporin resistance in Asia, 54 available Neisseria gonorrhoeae isolates collected in San Francisco, CA, from January to October 2008 were analyzed. Five isolates tested positive for the mosaic penA gene by real-time PCR. DNA sequencing revealed two mosaic penA alleles (SF-A and SF-B). Isolates...

The expression of resistance to cephalosporins is highly varied and due to various mechanisms. The greatest disadvantage of the cephalosporins is that they are inactivated by the array of beta-lactamases produced by bacteria. The high levels of chromosomal enzymes produced by these organisms are a major cause of cephalosporin resistance. Plasmid-mediated beta-lactamases (PMBLs) have also been i...
