Efficiency of viral entry determines the capacity of murine erythroleukemia cells to support persistent infections by mammalian reoviruses.

abstract：:Six phages were isolated from sewage and from a lysogenic strain. Three of them, belonging to a new morphological group, had contractile tails and elongated heads with axial ratios of 2.4:1. Two phages, possessing short tails and very long heads with axial ratios of 3.5:1, were new isolates of an extremely rare group....
