Isolation of three different bacteriophage from mesophilic Aeromonas sp. that use different types of monopolar flagella as their primary receptor.

Bacteriophage PM4, PM5 and PM6 were isolated on different mesophilic Aeromonas strains. These bacteriophage use the flagellum as their primary bacterial receptor since purified flagella from these strains are able to inactivate these bacteriophages, independently, and the phage-resistant mutants are aflagellate and nonmotile. Furthermore, we showed that these bacteriophage may be useful to initiate the serotyping of mesophilic Aeromonas for the H-antigen (flagellum).
