Adenovirus Type 7 Genomic-Type Variant, New York City, 1999
Figure 2. DNA fragment patterns obtained with selected restriction enzymes of representative outbreak (1) and community (2) Ad7 isolates resolved by gel electrophoresis with ethidium bromide staining. DNA markers III (λHindIII/EcoRI) and VI (pBR328 BglI/HinfI) were run simultaneously to facilitate fragment size estimates. Arrows highlight loss of 2,500- and 12,700-bp fragments and corresponding appearance of a new 15,200-bp fragment for the outbreak strain (1) as compared with the expected pattern for Ad7b (2).
