A Study on Production and Sensitivity of Local Strains of M. morganii to Morganocins

In the present study, 20 types of morganocins were prepared from 19 isolates of Morganella morganii isolated from infantile diarrhoea patients in addition to one standard strain (Cod No. A236).
The activity effects of morganocins showed variations on the isolates used. Some had a wide spectrum (inhibited 68.4% of the isolates) while the others had a narrow spectrum effect (inhibited 5.3% of the isolates).
Variations in the activity were also observed in the sensitivity of isolates to the different morganocins. One strain only showed resistance to all morganocins, therefore the percentage of the sensitivity of strains was 95%.
