[Autoradiographic study of a bacterial colony. Application to the effects of polymyxin on Pseudomonas aeruginosa colonies].

The autoradiograph of a colony of Ps. a. which has been transferred, during growth, on a medium added with polymyxin and tritiate leucin makes it possible to locate an upper zone with a high metabolic activity and a basal zone with no metabolic activity. The latter, which consists of lysed cells, acts probably as a selective filter against the drug.

[Resistance to association of antibiotics (polymyxin and penicillin) in relation to cell concentration of two bacterial species in the same inoculum. Complementary inoculum effect].

Dense suspensions of Sa. typhi (Polys Penr) and of St. aureus (Polyr Pens) proliferate on gelose medium added with the two antibiotics only if the inoculum is mixed. The growth is probably due to the partial neutralization of the antibiotics following the formation of complexes between these antibiotics and some constituents of the two strains.
