Gonorrhea is one of the most common venereal diseases in the world. Antibioticresistance development has been an issue with the penicillinase-producing Neisseria gonorrhoeae(PPNG) development. It is possible for PPNG to be resistant to other medications. Therefore, it is significant to determine its frequency rate and its disposition.

In this surveillance, we examined overall development frequency of PPNG from 1981 ti 1998. Comparing current five years' frequency rate with that of previous five year, we predicted possible development rate and described the procedures the physicians must take into account in gonorrhea treatment.

We examined the development frequency of PPNG in male patients of the venereal disease clinic of Jung-gu Community Health Center in Seoul from 1981 to 1998. Also, we analyzed the overall tendency with time series analysis using statistics package, SPSS 7.5.Grouping the years in five-year units, development frequency of PPNG of current five years (1994-1998) was compared with that of previous years.

For the result of monthly analysis of frequency rate of PPNG development from 1981 to 1998, the rate tendency came out with a sligh rise (slope : 0.15). And for the result of comparison of grouped years, in current five years, its rate was 51.6%, marking a significant decline from that of the previous five years, which was 57.2% (p-value : <0.0001).

The rate of current five years was reported to have declined from the previous years. However, the rate is still over 50%. Therefore, the government should continue the PPNG surveillance with test of sensitivity of the medications in use. Moreover, to eliminate gonorrhea, the education on high risk groups should continue and physicians should use a dose of adequate antibiotics in treatment.
