title: Ampicllin sensitivity and biotypes of recent Danish isolates of Haemophilus influenzae.
abstract: Among 148 strains of Haemophilus influenzae isolated in 1975 from different localities in Denmark, none was found to be resistant to ampicillin. A majority of the strains belonged to biotypes I, II and III and the presence of a partial correlation between biotype and origin was confirmed.
