Because of their ability to infect bacterial cells, bacteriophages or phages (viruses
that infect and kill bacteria) show promise in treating diseases caused by
multidrug resistant bacteria like the Burkholderia cepacia complex (Bcc). In order
to carry out their lifecycle, phages must recognize, adsorb to, and inject their
genetic material into the host. Host recognition is a crucial stage during phage
infection and is divided in two main stages: a) reversible binding, characterized by
low affinity binding of the phage to a secondary receptor in the outermost
membrane of the host, and b) irreversible binding, characterized by a high affinity
binding of the phage to its primary receptor. A wide variety of phage receptors
have been characterized including lipopolysaccharide, pili, flagella, porins,
capsules, and ligand-gated porins. Two random plasposon insertion libraries were
screened against a collection of Bcc specific phages. Bacterial mutants resistant to
phage infection were then isolated and the disrupted genes and proteins involved
in phage adherence were characterized. -
