title: Ceftazidime resistance in Hafnia alvei.
abstract: Two morphotypes of Hafnia alvei differed in their susceptibilities to beta-lactam antibiotics. Both produced an inducible Bush group 1 beta-lactamase. Hyperinducibility of this enzyme was associated with reduced susceptibility in one morphotype.
