National Reference Center for Neisseria Gonorrhoeae (NRCNG)

The Unit

The National Reference Center for Neisseria gonorrhoeae (NRCNG) at the Laboratory of Bacteriology of the H.P.I. was officially established in 1987 upon authorization by the Greek Ministry of Health (Α1/5755/15-6-1987). Research on N. gonorrhoeae has actually been an ongoing project in this laboratory since 1981. The NRCNG aims to achieve continuous surveillance of the epidemiological and antibiotic resistance trends of gonococcal infection in Greece.

Sample supply: 155 isolates annually (average for the yars 2005-2009).

Activities

The NRCNG:

  • Conducts a regular data collection of gonorrhea cases recorded in venereal hospitals or other medical care units throughout Greece.
  • Receives gonococcal isolates, performs detailed typing and antibiotic susceptibility testing. Gonococcal collection of the NRCNG enumerates today more than 3.000 well characterized strains.
  • Analyzes the underlying mechanisms responsible for resistance in gonococci presenting resistance patterns newly appearing or widely disseminated in Greece.
  • Educates scientists and technologists and supervises PhD students on research projects relative to gonorrhea epidemiology and gonococcal resistance to antibiotics.
  • Evaluates data and reports to the Greek Ministry of Health, while keeping up to date the Greek and international scientific community with data ensued from this evaluation. The main findings of the annual reports of the NRCNG are also presented in the website of H.P.I. (see Proceedings 2009)
