Competent Haemophilus influenzae bacteria were exposed to purified phage HP1 DNA and then plated for transfectants (PFU). When 32% (final concentration) glycerol was added before plating, between 10- and 100-fold more transfectants were observed. Glycerol had no significant effect on transfection with DNA from single or tandem double lysogens. It also had little effect on transformation with ch...

1. It has been shown that the ability of virulent S. influenzae to kill mice is enhanced by suspending the organism in mucin. 2. The occurrence of a true infection characterized by in vivo multiplication of the organism has been established. 3. The necessity for using a pure inbred strain of mice for this type of study has been confirmed. 4. The increase in mucin virulence of a strain of H. inf...
متن کاملEffect of antibiotics on adherence of Haemophilus influenzae type b.
During antibiotic therapy for serious Haemophilus influenzae type b infections in children, respiratory mucosal colonization with this organism is suppressed but not eradicated. To define possible mechanisms contributing to this suppression, the ability of six antibiotics to influence the adherence of H. influenzae type b to human epithelial cells was investigated. In assays in which the organi...
