A total of 12R^+ strains were treated with sublethal concentration of each drug for 18 hrs. Then, cells were streaked on the heart infusion agar plate and drug resistance of each colony was tested. Thus, a total of 4,310 colonies were investigsted. The frequencies of elimination were very low, such as 0.98% in FZ, 0.80% in FM and 0.75% in PFS. These values were rather low as compared with 2.92% in acriflavin and 1.27% in SDS which were obtained as control. 2. To investigate whether the specific action of the drugs on R^+ strains could be obtained, the average minimum inhibitory concentration (MIC) of 108 R^+ and 193 R^- strains was calculated and was compared. As control, MIC of 193 susceptible (S) strains for AB-PC, SM, TC, CP, KM and SA was also obtained. There were no differences between average MICs of the R^+ and R^- in any drugs, however, the average MIC of the S strains was significantly lower than those of the R^+ or R^- strains. From the results obtained, the author could not conclude that the 3 drugs, FM, PFS and FZ, have eliminatory action on R factors and also specific action on R^+ strains of E. coli.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"琉球大学農学部","subitem_publisher_language":"ja"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/4308"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0370-4246","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AN00250548","subitem_source_identifier_type":"NCID"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_source_title":"琉球大学農学部学術報告","subitem_source_title_language":"ja"},{"subitem_source_title":"The Science Bulletin of the Faculty of Agriculture.
