Both of those of our approaches inoculate in two different types of media for detection of aerobic and anaerobic microorganisms. We test bulk and remaining drug products, in addition to raw resources. We also carry out bacteriostasis/fungistasis tests to evaluate if microorganism expansion is inhibited.
The focus of this article is surely an OOS investigation; even so, the principles are relevant to all analytical laboratory investigations.
Initial time and refresher coaching and awareness about simple microbiology to operators Doing the job within an aseptic environment makes sure that operators are continually produced aware of the criticality of aseptic operation.
