# For 2005, all strains submitted to the National
Reference Laboratory for Pathogenic Neisseria, Örebro,
Sweden and to the Karolinska
University Hospital Huddinge, Stockholm, Sweden are presented.
* Minimum inhibitory concentration (MIC) in mg/L.
** PPNG strains are not included; 1998 (n=266), 2000 (n=83), 2001
(n=89), 2002 (n=73), 2003 (n=102),
2004 (n=110), and 2005 (n=384).
*** For ciprofloxacin, different SIR breakpoints are
used at the two laboratories. Consequently, strains with
decreased susceptibility or
resistance are compiled.
