Another temperature vary would depart from the USP method, however, you can normally use alternatives methods as described in the General Notices from the USP and USP.
Growth indicative properties shall be executed for your selective media as mentioned in Desk –I and history the observations in Annexure II.
28. If we have growth complications of S. aureus and inhibitory issues of E. coli with mannitol salt agar medium that is suggested from the harmonized method, exactly what is the lead to?
