IS1311 PCR-restriction endonuclease analysis profiles for DNA extracted from tissues. Lanes 1, 2, and 4 are IS1311 PCR products from DNA extracted from gut tissues restricted with Mse I and Hinf I enzymes. Lanes 3 and 5 are IS1311 PCR products from DNA extracted from lymph node tissues restricted with Mse I and Hinf I enzymes. Lane 6 is negative control. Lane 7 is IS1311 PCR product from S strain restricted with Mse I and Hinf I enzymes. Lane 8 is the unrestricted IS1311 PCR product from S strain. Lane 9 is the molecular size markers (Number VIII).
