The authors supposed that the fact might be resulted from prevalence of antibiotic resistant strains of Erysipelothrix insidiosa. The present study, therefore, examined for sensitivity to 6 antibiotics by means of plate dilution method using 48 strains of E. insidiosa which isolated from different forms of swine erysipelas. 1. All the strains tested were sensitive to penicillin (PC) of which average minimum inhibiting concentration (MIC) was 0.384 units. Erythromycine (EM) was the most effective and its MIC was 0.030μg, followed by oxytetracycline (TC) 1.723,chloramphenicol 7.162,and streptomycine 29.817. All the strains except one were resistance to kanamycine (KM). 2. There were no differences in sensitivity to PC among the strains isolated from acute and chronic forms and also among stock cultures which supposed to be not exposured to PC and recently isolated strains. 3. Artificial induction of PC resistant strain in vitro was difficult to make any of the resistant strain. 4. From the above results, PC was consistently found to be more effective antibiotic against E. insidiosa. The possibility of the erysipelas organism becoming resistance to PC was negated. 5. One strain of which patterns of sensitivity to EM, TC and KM were different from others was isolated from endocarditis form. This character may possibly be used as one of genetical markers of E. insidiosa.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学農学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/4442"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0370-4246"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250548"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学農学部学術報告"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
