Abstract

Background: Siphoviridae virions often possess lytic domains facilitating host-penetration. Results: Tuc2009 and TP901-1 virions may contain full-length or truncated tail fibers, possessing or lacking a lytic domain, respectively. Conclusion: Phages with a lytic domain infect stationary phase cells better, whereas truncated derivatives have higher adsorption efficiencies. Significance: The heterogeneous phage population serves to most effectively infect bacteria where levels of cell wall crosslinkage differ.
