METHOD FOR PREPARING STABLE BETA-LACTAM-TYPE-ANTIBIOTIC SUSCEPTIBILITY TEST DISCS

摘要

Discks which can be used to determin susceptability of phathogenic microorganisms to the absorbed antibiotic, were prepd. by suspending crystals of β-lactam type antibiotic in isopropanol, absorbing the suspension on the absorbant materials as α-cellulose paper which did not affect susceptibility of phathological microorganisms and which was stable under storage conditions, and evaporating isopropanol.
