Microbiological
quality control of pharmaceutical water systems is of importance in ensuring
that trends in contamination are detected and responded to. This is not least
because water is a niche environment for many types of microorganisms and a
vector for their transfer. Trending relates to actual microbial counts
recorded, incidents and the types of species recovered. To facilitate species
identification, microorganisms need to be subcultured from the isolation medium
(R2A agar in Europe). Transfer onto the wrong media can result in the
microorganism not growing. This paper describes research into three different
media for subculturing: low nutrient (R2A); highly nutritious (TSA) and medium
nutrient (R3A) and concludes that a higher recovery is obtained where R3A agar
is used.
