Si·pho·vir·i·dae

(sī'fō-vir'i-dē),
A family of bacterial viruses with long, noncontractile tails and isometric or elongated heads, containing double-stranded DNA (MW 25-79 × 106); includes the λ temperate phage group and probably other genera.

coli phages, designated bacteriophages oEU-3 and oEU-4, showed that they belong to the family Siphoviridae and Myoviridae, respectively.
Dimensions and titration of the isolated phages Phage Prospected Head Tail Phage titer (PFU/ml) Family diameter length (mil) (mil) oEU-3 phage Siphoviridae 71.42 214.28 2 x [10.sup.7] oEU-4 phage Myoviridae 66.6 108.3 2 x [10.sup.5]
Results revealed that phages belonging to the Siphoviridae family (P-3, P-4, P-6, and P-7) had a very short latent period of 12-23 min.
The average burst size of tested phages was about 329 phages per infected cell, which is more than the typical range of 50-100 PFU [cell.sup.-1] for many Myoviridae and Siphoviridae phages [77, 78].
British scientists have isolated the virulent bacteriophage CTP1, which belongs to the Siphoviridae family of double-stranded DNA viruses that infect only bacteria.
The phage [PHI] SH-56 had an icosahedral head, about 70 nm in diameter, and a 100-nm long tail, thus morphologically similar to phages belonging to Siphoviridae family
Isolated phage is classified into order Caudovirales and since it possess a long noncontractile tail and icosahedral capsid head, thus is a member of the family Siphoviridae (28).
Here we established a classification scheme for staphylococcal prophages of the major Siphoviridae family based on integrase gene polymorphism.
