A total of 610 strains of E. coli (235 from Japanese Blacks, 228 from imported cattle and 147 from F_1 hybrid) were isolated and antibiotic sensitivity tests to ABPC, CP, CTC, KM, SM, NA and SA were performed. Of the 610 isolates, 136 (22.3%) were resistant to one of the antibiotics tested. The antibiotic-resistant E. coli isolation rate was 30.6% in Japanese Blacks, 16.7% in imported cattle and 17.7% in F_1 hybrid. The overall antibiotic resistant rates were 12.8% and 10.2% for CTC and SA, respectively, and less than 5% for the other antibiotics. Fourteen antibiotic resistance patterns, ranging from single-agent to 4-agent resistance were detected : eleven patterns in imported cattle, 9 patterns in Japanese Blacks and 6 patterns in F_1 hybrid. While 62 to 71% of the strains isolated from imported cattle and F_1 hybrid were resistant to a single agent, over 50% of the strains from Japanese Blacks were resistant to 2 or more antibiotics. Transmissible R plasmid were examined in the antibiotic resistant E. coli strains. Of the 126 strains examined, 16 (12.7%) possessed transmissible R plasmids. They were found in 20% of the resistant strains from imported cattle, 11.5% of those from F_1 hybrid and 10% of those from Japanese Blacks. The type of transmissible resistance was all one-agent type.","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/20.500.12000/3743"}]},"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.
