This details serves to point the post is not likely to generally be contaminated With all the specified species of microorganism. Monitoring should be continued to be able to determine the spectrum of inhibition and bactericidal activity with the report.
At the same time, the poisonous metabolites of microorganisms and many pathogenic microorganisms may result in adverse reactions or secondary infections to people. Hence, microbial limit testing for non-sterile drug products is among the significant measures to ensure the standard, basic safety and efficiency of medication.
