title: Multilocus enzyme analysis of African type penicillinase-producing Neisseria gonorrhoeae (PPNG) strains isolated in Spain.
abstract: Variability among 38 penicillinase-producing and non-producing Neisseria gonorrhoeae (PPNG and non-PPNG) strains that were isolated in Spain was investigated by multilocus enzyme electrophoresis. Based on the results of the analysis at six enzymes loci, the strains were separated into three closely related electrophoretic types (ETs). The average number of alleles by enzyme locus was 1.33, and the mean genetic diversity by locus was 0.235. This group of gonococcal was genetically uniform.
