A total of twenty Strdins of Escherichia coil isolatu3 from pigs was examined for sensitivity in vito of Carindox and other antibacterial drugs under aerobic and anbicconditions. The results obtainal axe summarilas follows (Table 1): With aerobic condition, it was shown that the growth of B coil was inhibit! with Carbadox at 25- 1CO.tghnl, The activity of the drug, however, was extemely enhanced die to the

On the other hand, the sensitivity of the other antilnrial drugs as aminokenzyl rtnidl]in and furatrizin were abcut as same result in both aerobic and anaerobic conditions.
