Phase contrast microscopy illustrating MR/K agglutination. Parental wild-type strains C. koseri M546, E. coli ECOR15, K. oxytoca M126, K. pneumoniae M692 and C. freundii M46 demonstrated strong agglutination of tannic acid treated human erythrocytes, while their corresponding mrk deletion mutants, M546mrk, ECOR15mrk, M126mrk, M692mrk and M46mrk were negative for agglutination.
