These evaluations need considerable teaching and encounter in microbiology. get more info Knowledge the methodology, plus more importantly, knowing the limitations of the test current the tougher problems. For instance, a maker identified higher counts of Enterobacter cloacae within their oral dosage type solution derived from a organic material. Because they did not isolate E. coli, they produced the products. FDA analysis uncovered E. cloacae for most samples with the batch and in many cases E. coli in a single sample. In cases like this management failed to acknowledge that microbiological contamination may not be uniform, that other organisms may well mask the presence of specified organisms when identification procedures are done, and that microbiological testing is way from absolute.
