Among these bacteria, 196 strains of Staphylococcus (Sta.) epidermidis the most frequent, followed by Sta. aureus (80 strains), Streptococcus (Strep.) (62 strains), Corynebacterium (Coryne.) (45 strains) and finally Pseudomonas (Pseudo.) (13 strains) were cultured. Drug sensitivity test was performed in these 396 strains, employing PCG, SP, CP, CTC, KM and SM. Minimum inhibitory concentration (MIC) was measured. Resistance against and antibiotic was defined as growth against the concentration of 1.56u/ml PCG (25u/ml for Pseudo.). In 5 other drugs, resistance was defined as growth against the concentration of 12.5μg/ml (25μg/ml for Pseudo.) or above. The rate of appearance of strains resistant to one of the 6 drugs was 100% for Pseudo, 62.9% for Strep, 29.6% for Sta. epidermidis, 22.5% for Sta. aureus and 22.2% for Coryne. The resistance pattern in the resistant bacteria was mostly to PCG alone in Sta. aureus. With Sta. epidermidis, resistance pattern was SM alone, followed by double resistance of CTC-SM. With Strep., most of the bacteria showed resistance pattern of KM-SM. A few strains showed resistance in Coryne., but resistance to drugs other than PCG was noted. Some strains were resistant to 3 or 4 drugs. All 13 strains of Pseudo. were resistant to 3∿4 drugs, and a tendency for resistance to multiple drugs.","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/20.500.12000/3971"}]},"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.
