hi,i would like know why we test only E.coli,Salmonella,Pseudomonasand Staph.aureus alone for testing of pathogens.
We analyze four pathogens only because in pharma major source of contamination is water and human beings. E.coli, Salmonella and Pseudomonas are most common water contaminants if these are absent then we are confindent enough to say that rest of the contaminants will also be absent. As far as S. aureus is concerned it comes form human intervention.
thankyou for your information.
