Hospitals are breeding grounds for bacteria, because the use of
antibiotica there leads to the emergence of antibiotic-resistant
strains of bacteria. In a hospital one may get an infection that is much
worse than the ones one gets in normal surroundings where all bacteria
have to compete equally among each other. Small amounts of Pseudomonas 
may occur in healthy people, but they usually cannot increase in 
number because of the presence of other, harmless bacteria. If the later are 
killed by antibiotics, the Pseudomonas may increase to take their place.
Pseudomonas can be killed, but one has to culture the strain first to
see which antibiotic can kill this special variety. Best guesses would
be an acylureidopenicillin (e.g. piperacillin) or a carboxypenicillin.
