[Problems of variability of Mueller-Hinton medium for sensitivity testing. Some parameters and an attempt to standardize sensitivity of Salmonella typhi].
The incidence of some so-called "Mueller-Hinton Medium" for sensitivity testing on the growth of bacteria (especially S. typhi) and on the drug activity are evaluated here. The role of the quality and amount of ingredients : peptone, agar and starch are emphasized. An improved medium is proposed : tryptophane is added to compensate the casein hydrolysate deficiency for S. typhi growth.
