Adsorption experiments of phage K5-2. Preincubation of phage K5-2 with its host the K5 reference or Co39 (K30) strain and determination the viral titers on the reference K5 and Co39 (K30) strains, respectively. Negative reactions were observed on the reference K8 strain. The data represent the means of three independent trials; the error bars represent the standard deviations. **P < 0.01 by Student’s t test (compared to the viral titer of the respective host before incubation).
