Post‐antibiotic effect of cephalexin against

The post‐antibiotic effect in vitro (PAE) of cephalexin was determined according to a broth dilution method against 5 isolates of Staphylococcus intermedius obtained from cases of canine pyoderma Two durations of exposure and 3 concentrations were tested The PAE increased when time of exposure or concentration increased The mean PAE ranged from 0 7 to 3 3 h

Antibiotics Facts for Kids

The term antibiotic was first used in 1942 by Selman Waksman and his collaborators in journal articles to describe any substance produced by a microorganism that is antagonistic to the growth of other microorganisms in high dilution This definition cut out substances which kill bacteria but are not produced by microorganisms (such as gastric juices and hydrogen peroxide)

MIC Method

From this example Tube C (with 0 1 ug/ml of antibiotic) did not inhibit bacterial growth Tubes A and B on the other hand did inhibit growth Tube B has the minimum inhibitory concentration because B is the lowest concentration of the antibiotic that inhibited cell growth Therefore the MIC for this bacterium is 1 g/ml Advantages
