Of 152 pig isolates, only 5 (3.3%) were sensitive to all 6 drugs (APC, TC, SM, CP, KM and SA) used, and other 147 (96.7%) were resistant to one or more drugs. Out of the 147 resistant strains, 65,or 44.2%, were found to transfer all or a part of their resistance patterns to the drug sensitive recipient strain. The resistance patterns of R factors were classified into 16 different patterns, in which 2 patterns, APC-SM-KM and TC, comprised more than 50% of all R factors identified. On the other hand, of 221 strains isolated from chickens, 209 or 94.6%, were drug resistant strains. Seventy-six of the 209 (36.4%) were found to carry R factors, and a total of 9 different patterns of R factors were identified. The most commonly occurring resistance patterns of R factors were patterns of TC, SM, and TC-SM. These 3 patterns of resistance accounted for 76.3% of all R factors detected in chicken isolates. In regard to data of drug resistance and distribution of R factors, there were some differences between strains isolated from pigs and chickens. However, it could be concluded that a high incidence of resistant strains did exist in these animals in Okinawa, and that R factors were widespread among these resistant strains.","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":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/4388"}]},"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.
