Bacteriophages active towards pathogenic microflora are usually acquired from the material obtained from a given patient (urine, faeces, pus, etc.).
The other alternative which further gained wide spread was the isolation of virulent phage isolates from sewage waters (normally from the clinic)
Bacteriophages (Cell lysis video) available for therapy applications belong
to the Order Caudovirales divided into three families:
Myoviridae
Podoviridae
Siphoviridae
This is the list from ITCV(International Committee on Taxonomy of Viruses) with Order, family and genus names.
