To confirm the effect of this control for incidences of drug resistant and R factors-carrying (R^+) E. coli strains, the present experiments were performed. A total of 2,455 E. coli strains isolated from rectal swabs from 40 piglets of 4 litters during first 60 days of their lives were tested for resistance to 6 antimicrobial drugs, i. e. APC, SM, TC, CP, KM, and SA. The experimental periods, for convenience, were divided into 6 stages as follows; stage I, 0 (the day of birth)-1 day after birth; stage II, 2-5 days; stage III, 6-10 days; stage IV, 11-20 days; stage V, 21-35 days and stage VI, 36-60 days. The results are summarized as follows : 1. A relatively high proportion (46.4%) of the strains of stage I was resistant to drugs, mainly to TC, and the proportion gradually increased until stage IV. At stage V, however, the percentage of resistant strains markedly increased up to 86.1% with sudden increase in those of KM resistant strains. This tendency continued until stage VI, when the percentage was 98.1. 2. Totally, of 2,455 strains, 1,568 (63.9%) were found to be resistant. The percentages of strains resistant to TC, SA, SM, KM, APC and CP were 46.6,33.2,29.2,16.4,3.3 and 0.9%, respectively. 3. Isolation frequencies of multiple resistant strains were increased with the lapse of days after birth of piglets from which the strains originated. At stage VI, 95.0% of strains tested were multiply resistance, of which patterns were mainly composed of SM, TC, KM and SA. 4. Of 1,568 resistant strains, 390 (24.9%) were found to carry R factors. The isolation frequencies of the R^+ strains among the reistant strains at stages I to VI were 3.6,6.0,8.4,27.2,48.2 and 38.5%, respectively. 5. Isolation frequencies of resistant and R^+ strains among 256 fecal E. coli strains isolated from 4 sows from which the piglets were derived were also tested and compared with those of piglets. No definite relations which may support a vertical contamination of resistant strains were obtained. 6. From the data obtained in the present experiments, it could be said that incidence of drug resistant strains was uncontrollable only by taking off the drugs from animal feeds. Therefore, clean up of already contaminated environments should be necessary.", "subitem_description_type": "Other"}, {"subitem_description": "\u7d00\u8981\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8"}]}, "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/20.500.12000/4172"}]}, "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": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8\u5b66\u8853\u5831\u544a"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "The Science Bulletin of the Faculty of Agriculture.
