Figure 1From: Characteristics of β-lactamases and their genes (blaA and blaB) in Yersinia intermedia and Y. frederikseniiTypes of restriction profiles of blaA with NciI (Lanes 1–2) and HaeIII (Lanes 3–5), and blaB with HaeIII (Lanes 6–7) and RsaI (Lanes 8–9). PCR amplification and restriction analysis were carried out for 49 strains of Y. intermedia and Y. frederiksenii. M, molecular weight DNA marker (100 bp DNA ladder)Back to article page
