Abstract
Two bacteriophages isolated onEnterobacter cloacae (C2, C2F) and three isolated onErwinia herbicola (E3, E16P, E16B) were purified by D2O gradient centrifugation. Phage-containing fractions were negatively stained and examined by electron microscopy. Phages C2, C2F, E3, and E16P showed an elongated head 153×51 nm and a short noncontractile tail 12 nm long terminated by at least two short fibers. These phages correspond to the rate taxonomic group C3. Big capsomeres composing the phage head were evidenced when phage suspensions in D2O were stained. Phage E16B showed an elongated head 97×40.5 nm, and a contractile tail 89 nm long. This phage corresponds to the extremely rate group A3.
