Genetic Diversity of Paired Middle-Ear and Pharyngeal Nontypeable Haemophilus influenzae Isolates from Children with Acute Otitis Media▿

摘要

Pulsed-field gel electrophoresis was used to determine genetic diversities of multiple nontypeable Haemophilus influenzae isolates from throat and ear specimens of eight children with otitis media. From five children, all ear and throat isolates were identical. The bacterial populations in these specimens showed less diversity than populations in throat isolates of healthy children.
