DNA fragments of Cn and Cc/Cl isolates obtained after multiplex PCR amplification of LAC1 and CAP64 genes. Lanes 1, 2, 9 and, 10, Cn serotype A profile. Lane 3, isolate of Cl and lanes 4–7 and 8, isolates of Cc. M, molecular weight marker. The Cc/Cl isolates thus gave DNA bands of different sizes and numbers from the reference profiles. While the Cn isolates had given the characteristic major band of serotype A of about 760 bp and a small band of 420 bp, the Cc isolates had the first band of about 1100 bp and a second of 800 bp, and the Cl isolates had a band of about 900 bp and another of about 600 bp, profiles that don’t match with those of different serotypes of the Cn/Cg complex
