Figure 1: Agarose gel (0.8%) indicating identification of amplified gene of penicillinase-producing plasmid of various clinical isolates using primers according to Dillon et al. (1999). Lane1represents Asian-type plasmid (isolated from WHO N strain), Lane 3 represents African-type plasmid (isolated from WHO M strain), Lane M is 1 Kb marker and Lane 4–6 represents various clinical isolates. All three clinical isolates showed a band of 3.1 kb indicating the presence of African-type plasmid.
