Bacterial Receptors but Not Anti-Phage Defense Mechanisms Determine Host Range for a Pair of Pseudomonas aeruginosa Lytic Phages

Dea M. Müller, Julie D. Pourtois, Minyoung Kevin Kim, Bobby Targ, Elizabeth B. Burgener, Carlos E. Milla, Maryam Hajfathalian, Hemaa Selvakumar, Joel Berry, Max Hopkins, Robert McBride, Jyot D. Antani, Paul E. Turner, Jonathan L. Koff, Paul L. Bollyky

The paper identifies bacterial receptor genes determining phage host range, showing defense mechanisms are not predictive of susceptibility.
