The development of antibiotic-resistant bacterias inside
hospitals is a main menace for the health of the patients.
Viruses too seem to develop. They are generally not dangerous
for healthy persons but can kill weak persons in a few days.
Some hospitals have become so infested they've been closed by
the authorities and destroyed using napalm. If most infections
due to those resistant bacterias are not lethal, they are
nevertheless a curse for the patients and a threat to the
hospital's reputation.
One solution could be the following: use well-chosen
unicellulars and bacterias to be sprayed inside the chambers, or
directly into the patients cloths and bandage. Their role would
be to swallow and digest every organic body they encounter,
including the dangerous bacterias and viruses.
Those unicellular and bacterias should have some qualities:
They should not attack the patient himself. Or be easily curable.
Cause no allergy reaction with the substances they produce. Or
those allergies should be handleable.
Be no vehicle for the pathogenic bacterias and viruses,
nor be a way for them to multiply.
Produce no bad smell or smudge, anyway for those intended for the
walls.
Such inoffensive unicellular and bacterias can be found in
forests or the like. They can be selected and mass produced in
factories just like brewer's yeast or milk ferments are.
Best is probably to continuously inject fresh cultures into
the hospital chambers, maybe through the ventilation. The
metabolites they produce and their dead bodies or spores will be
wiped away through the normal cleaning procedures.
In some cases, a chamber can be closed, its temperature and
its hygrometric level risen, and massive quantities of
unicellulars and/or bacterias injected so they will be able to
move around and scour every possible interstice.
The materials on the ground and walls can be chosen to allow
the unicellulars and bacterias to proliferate. Usually,
non-porous materials are preferable because they make
cleaning and disinfection easier. Now on the contrary highly
porous or fibrous materials could be used, perhaps even earth
for plants. Some very small insects, spiders and worms could
become part of the system too.
I heard viruses are used to fight pathogenic bacterias in wounds.
