Discussion of all aspects of biological molecules, biochemical processes and laboratory procedures in the field.
Because it is a bacterial virus? Because it thus won't find any surface receptor adapted to trigger DNA injection? And because probably it wouldn't then be able to replicate?
Many reasons, don't you think?
does a bacteriophage have RNA or DNA? or maybe the proteins on the surface of a bacteriophage would pobably not match the suface molecules of a human cell?
hmm...Also i suppose if bacteriophages are heterotrophs they could infect a human cell. Any thoughts?
If it would infect a human cell, would it still be a bacteriophage?
Um, E.coli is a bacteria located inside our body also...would Bacteriophage infection to these bacteria can be called infection to human?
Q: Why are chemists great for solving problems?
A: They have all the solutions.
Bacteriophages are safe to human since they do not enter eukaryotic cell, they can even be picky about which bacteria they infect... In fact phage typing is a method used to differntiate between strains of a same bacterial species (or subspecies as in Salmonella enterica Typhimurium DT 104, DT stands for "Definitive Type" and is defined as a pattern of resistance and sensibility to some phages...). In fact some people even suggest that phage therapy could be a good way to cure bacterial infections, but there are still too many problems for it to reach bedside yet.
As for the deleterious effect of a phage to our gut, in theory it could be true, but since we ingest plenty of phages all the time, the experience proves that they are not all that potnt in term of bactericidal effect and that our flora is diverse and rich enough to fill in every gap that may be created. In this respect the wide spectrum of antibacterial activity of antibiotics is probably much more deleterious.
Hmm... I don't think so... I can't imagine any scenario like that...

Any bacteriophage causing the production of harmful compound? No. Yet...
Yet some bacteriophages can cause transduction of genes, and those genes can be resistance genes or pathogenic islands, and thus can be considered harmful! SO the scenario is not absurd at all...
