Numerous pathogens or, much more particularly, metabolites which they produce, Have got a ability to either break down or inactivate the drug compound.

The foremost supply of microbial contamination of controlled environments will be the staff. Contamination can arise in the spreading of microorganisms by individuals, specially People with active bacterial infections. Only healthful individuals really should be permitted entry to managed environments.
