Essais de dosage d'antibiotiques dans le lait


Laboratoire des Fermentations de l'Institut Pasteur de Lille

Abstract - The method described permits knowledge in twelve hours of the quantity of aureomycin and penicillin contained in whole or skim milk, to the exactitude of 0,5. It can be used on a concentration up to 5 units per mL, without necessitating recourse to numerous dilutions which are used in acidimetric methods, which may be more rapid, and which are described by certain authors for the determination of concentrations lower than one unit per mL.
In order to be valid, the determinations should be done under strictly identical conditions of insemination and titration, using only species whose acclimatization capacities and acidifying powers have been carefully verified and tested in the presence of increasing quantities of antibiotics
