"In silico"
From Wikipedia
If the target host* of a phage therapy treatment is not an animal the term "biocontrol" (as in phage-mediated biocontrol of bacteria) is usually employed, rather than "phage therapy".
In silico
From:"Genomics,Proteomics and Clinical Bacteriology",N.Woodford and Alan P.Johnson
Phrase that emphasizes the fact that many molecular biologists spend increasing amounts of their time in front of a computer screen, generating hypotheses that can subsequently be tested and (hopefully) confirmed in the laboratory.
Phage Therapy is influenced by:
Phage therapy is influenced by:
Country : the epidemiological situation is different from country to country in terms of circulating bacteria and bacteriophages. Example: lytic phages from Italy may be no active on the same bacteria (genus and species) isolated from another country and vice versa.
Temporariness
Mutation rate
Phenotypical delay
Phage cocktail

Phage therapy conditions
Phage therapy must be used in those conditions where the therapeutic success is elevated a priori.
Why?
a-Because Phage Therapy must maintain its best advantage : the RAPIDITY "GO, KILL and DISAPPEAR".
b- Because Phages must be Lytic and not modified by genetic engineering.
c-Because when we use the natural lytic phages in this SHORT TIME IS IMPOSSIBLE to have:
- a bacterial resistance that stops a phage attack ( 12 generations are necessary after a mutation of phage receptor in one bacterium for one phage and for this raison we use a minimum of two phages in the cocktail).
- an active immunological reaction ( two weeks are necessary).
- a bacterial resistance that stops a phage attack ( 12 generations are necessary after a mutation of phage receptor in one bacterium for one phage and for this raison we use a minimum of two phages in the cocktail).
- an active immunological reaction ( two weeks are necessary).
d-Because it is hard now to select phages and to prepare a phage cocktail by natural phages we can imagine how this will be with transformed phages.
e-Because with recombinant phages it is impossible to predict what will happen regarding the therapy and also the phage preparation is complicated and the use of these phages do not avoid the appearance of Phage Resistance.
f-For impeding the effect of the Endotoxin it is possible to use the Polimixina B.
If the abovementioned points are not adequately covered we must not use Phage Therapy .
