title: A region of Haemophilus influenzae Rd hybridizes with repetitive human DNA.
abstract: A 17.7 kbp EcoR1 fragment of Haemophilus influenzae Rd (wild-type strain) DNA containing repeats has been cloned together with the DNA repair gene uvr3. The region containing repetitive DNA was subcloned on a 13 kbp EcoR1 fragment (pHi13). The insert hybridizes with restriction enzyme digests of H. influenzae Rd and H. parainfluenzae and exhibits a repetitive pattern. Discrete bands superimposed upon a polydisperse background were observed when pHi13 hybridizes with restriction digests of human DNA. The hybridization patterns indicate that H. parainfluenzae and human DNA contain cross-hybridizing sequences. The repeats of pHi13 are present on a 2.6 kbp PvuII fragment.
