Abstract

The bexA genes of 36 Haemophilus influenzae isolates were sequenced to reveal their nucleotide sequence diversity, which divided them into two groups, similar to clonal divisions I and II. This sequence diversity may lead to false-negative PCR results for H. influenzae infections if bexA is the chosen gene target.
