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.

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].
Los 24 fagos tenian un peso molecular de 90kb y, segun sus caracteristicas morfologicas, 22 pertenecen a la familia Myoviridae, uno a la familia Podoviridae y uno a la familia Siphoviridae (Frampton et al.

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
Los colifagos somaticos son virus con ADN de cadena doble o sencilla, con capsides cubicas o complejas que tienen cabeza y cola; existen cuatro familias: la Myoviridae que se caracteriza por presentar un ADN de cadena doble con capsides de hasta 100 nm con colas largas no contractiles; la Podoviridae, presenta ADN de cadena doble con colas cortas no contractiles; la Microviridae: tiene ADN de cadena sencilla, con una capside de 30 nm sin colas y la Siphoviridae, es semejante a la familia Podoviridae, pero a diferencia de esta es la familia mas resistente junto con la familia Myoviridae, encontrandose la primera con mayor frecuencia en aguas localizadas lejos del sitio de polucion, mientras que la segunda se localiza en aguas recientemente contaminadas.
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.
