Abstract: | Hemagglutination of human type A and guinea pig erythrocytes showed that both mannose-sensitive and mannose-resistant adhesive mechanisms (pili) were detectable in broth cultures ofEscherichia coli while only a mannose-sensitive mechanism (type 1 pili) was noted withKlebsiella pneumoniae. The degree of hemagglutination was shown to be related to differences in erythrocytes, bacterial concentration, and growth media constituents.Escherichia coli grown in human urine produced both types of hemagglutinins, whileK. pneumoniae cultured in urine continued to express only a mannose-sensitive hemagglutinin. |
