要旨 | 【目的】 【方法と結果】イオン交換樹脂を備えた軟水器を用いて、Ca++とMg++をNa+に置換したUPSWを得た。蒸留水(DW)又はUPSWの中でStaphylococcus aureus(Staph. aureus)、Staphylococcus intermedius(Staph. intermedius)、Staphylococcus pseudintermedius(Staph. pseudintermedius)を各種脂肪酸塩と反応させた後、ブドウ球菌数を測定した。各種脂肪酸の中で、オレイン酸塩及びリノール酸(LA)塩はブドウ球菌数を減少させた。また、UPSWはブドウ球菌属に対するLAの抗菌作用を促進した。痒みを伴う皮膚炎を自然発症した伴侶犬において、10% LAを含む液体石鹸とUPSWを併用したシャンプー療法は皮膚のコンディションを向上させた。 【結論】 【本研究の重要性と影響】 (原文) Methods and Results: UPSW, in which Ca++ and Mg++ were replaced with Na+, was generated using a water softener with cation-exchange resin. Staphylococcus aureus (Staph. aureus), Staphylococcus intermedius (Staph. intermedius), and Staphylococcus pseudintermedius (Staph. pseudintermedius) were incubated with various fatty acid salts in distilled water (DW) or UPSW and the number of bacteria was counted. Among the fatty acids, oleic acid salt and linoleic acid (LA) salt reduced the number of these bacteria. Also, UPSW enhanced the antibacterial effect of LA on Staph. spp. In spontaneously developed itchy dermatitis in companion dogs, shampoo treatment with liquid soap containing 10% LA in UPSW improved skin conditions. Conclusions: LA salt showed antibacterial activity against Staph. spp. Treatment with soap containing LA with UPSW reduced clinical conditions in dogs with dermatitis. Significance and Impact of the Study: Because colonization of Staph. spp. on the skin exacerbates dermatitis, the use of LA-containing soap in UPSW may reduce unpleasant clinical symptoms of the skin. |
