In order to study the epidemiology of TEM-1 genes of Neisseria gonorrhoeae (Ng) in Wuxi area. In the light from foreign literature that positive Ng strains of beta-lactamase contain plasmid sequences of TEM-1 genes, heminested PCR for TME-1 genes of Ng detection was self-designed. Ng of 195 strains were detected, that were isolated in Wuxi area from Jan to the Oct, 2002. There were 138 TEM-1 genes positive in 195 isolated strains with a positive rate of 70.8%. There was one case of heminested PCR product of TEM-1 genes which showed the homogeneity was 99% in Wuxi area, when comparing with pFA7 sequences of positive Ng plasmid of beta-lactase from register GenBank. Data showed that the Ng strains with TEM-1 genes were the prevalent ones in Wuxi area.
