Abstract:
The typing set includes 27 tailed phages belonging to three families, the Myoviridae (contractile tails, 4 phages), Siphoviridae (long, non-contractile tails, 21 phages) and Podoviridae (short tails, 2 phages). Heads are isometric or elongated. The phages fall into 10 morphological groups, seven of which correspond to known enterobacterial phage species (Jersey, N4, T5, T7, ZG/3a, chi, 16-19) and one to a Rhizobium phage species (CM1). T5-type and T7-type phages are for the first time reported in salmonellae. Two phages produce large amounts of abnormal mottled heads.
