[Sensitivity of different strains of E. coli and Shigella to the inhibitory action of Ploskirev's bactoagar].

A study was made of the sensitivity of 190 strains of E. coli and 107 strains of Shigellae of different serological types to the inhibitory action of Ploskirev's bactoagar on the capacity of these bacteria to form colonies. The strains under study proved to be nonhomogenous in this respect: between different strains of E.
