Abstract
【課題】
薬剤耐性を持った菌による免疫力のない患者の日和見感染や、手術後の感染など重大な院内感染問題を軽減することを課題とする。
【解決手段】
抗菌性物質存在下に、405nmをピークとする400−410nmの波長を有するLEDを照射して、薬剤耐性を有する病原性微生物の当該抗菌性物質に対する感受性を増強する方法、および高濃度の抗菌性物質存在下にLEDを照射して、高度薬剤耐性を有するMRSA等の病原性微生物の出現を予防する方法を提供する。
【選択図】なし【Task】
The objective is to alleviate serious nosocomial infection problems such as opportunistic infections in patients without immunity due to drug-resistant bacteria and infections after surgery.

現在先進諸国においては、細菌やウイルスなどの多くの病原性微生物に対して有効な抗生剤が開発されており感染症の驚異は低下している。しかし、特定の病原性微生物に対して特定の薬剤を投与し続けると、やがて微生物は当該薬剤に対して耐性を獲得するようになる。近年、このようにして薬剤耐性を持った菌が出現し、日和見感染症や、菌交代症、新規な多剤耐性菌の出現による院内感染症が克服すべき問題となってきている。 In developed countries, antibiotics effective against many pathogenic microorganisms such as bacteria and viruses have been developed, and the wonder of infectious diseases is decreasing. However, if a specific drug is continuously administered to a specific pathogenic microorganism, the microorganism will eventually acquire resistance to the drug. In recent years, bacteria with drug resistance have emerged in this way, and opportunistic infections, fungal substitutions, and nosocomial infections due to the emergence of new multidrug-resistant bacteria have become problems to be overcome.
セフェム系抗生剤を含むベータ・ラクタム剤の多用に対して耐性を獲得したメチシリン耐性黄色ブドウ球菌(MRSA)が発現して社会問題となった後、さまざまな対策研究がなされた。MRSA感染症に対する新規な薬剤組成物として、抗生剤や抗菌剤、例えばアミノグリコシド系抗生剤、グリコペプチド系抗生剤、マクロライド系抗生剤、クロラムフェニコール、フォスホマイシンおよび/またはキノロン系抗菌薬に、フラボノイドを含有させた製剤を開示している(特許文献1)。多剤耐性結核菌による結核感染症の治療や予防効果については、薬剤耐性原生生物感染症患者より採取した血液中のリンパ球を、インターロイキン2等によって増殖・活性化させて主成分とした製剤が有効であることが開示されており(特許文献2)、バンコマイシン等の薬剤耐性菌保菌乃至感染している家畜・家禽・魚介類の感染防除剤としては、乳酸菌、特にエンテロコッカス・フェカリス(Enterococcus faecalis)、エンテロコッカス・フェシウム(Enterococcus faecium)、またはその死菌体、その処理物を有効成分とする薬剤が開示されている(特許文献3)。また、光照射によるMRSA耐性菌の殺菌方法としては、室内にフェオフォーバイドのナトリウム塩を含む水溶液を噴霧、散布又は清拭した後、室内に600〜700nmの波長を含む光を照射する室内の消毒方法が明かにされている(特許文献4)。光ダイオードによる殺菌方法に関しては、青色発光ダイオードアレイから閃光パルスを発生させて殺菌対象物に照射して殺菌する方法が開示されているが、光源が466nmをピークとする419−519nmの範囲の波長を持つものである(特許文献5)。
しかしながら、薬剤耐性を有する病原性微生物にLEDを照射して、病原性微生物の薬剤感受性を回復し、増強する方法は知られていなかった。本発明は、薬剤耐性を持った菌による免疫力のない患者の日和見感染や、手術後の患部からの感染など重大な院内感染問題を軽減することを課題とし、薬剤耐性を有する病原性微生物の当該抗生剤に対する感受性を増強する方法、および高度薬剤耐性を有する病原性微生物の出現を予防する方法を提供することをその主な課題とする。 However, there has been no known method for irradiating a pathogenic microorganism having drug resistance with an LED to restore and enhance the drug sensitivity of the pathogenic microorganism.

A diode having a near-ultraviolet wavelength (350-410 nm) is effective, and a near-ultraviolet diode having a wavelength of 400-410 nm with a peak at 405 nm (hereinafter referred to as 405 nm LED) is most appropriate when considering the influence on the human body and the environment.

薬剤感受性試験は、次のように行う。図1に示すように、検査対象菌を適切な固形培地上に塗布し、その上に試験する薬剤を含む濾紙を定着させる。カバーをした後、適切な培養温度で菌を増殖させる。このとき、薬剤の濾紙に近い培地には高濃度の薬剤が滲出し、濾紙から遠くになるに従いその薬剤濃度は低下する。検査対象菌の増殖不可能な薬剤濃度のところで、成育阻止円が形成される。その成育阻止円の半径により、検査対象菌のその薬剤に対する感受性(耐性)度が計測される。また、このときにLED光を照射すると、LED光による薬剤感受性変化を比較・測定することが出来る。 The drug sensitivity test is performed as follows. As shown in FIG. 1, the test bacteria are applied on a suitable solid medium, and a filter paper containing the drug to be tested is fixed thereon. After covering, the bacteria are grown at an appropriate culture temperature. At this time, a high concentration of the drug oozes out from the medium close to the filter paper for the drug, and the drug concentration decreases as the distance from the filter paper increases. A growth inhibition circle is formed at a drug concentration at which the test bacteria cannot grow. The degree of sensitivity (resistance) of the bacterium to be tested to the drug is measured by the radius of the growth inhibition circle. Moreover, when LED light is irradiated at this time, the drug sensitivity change by LED light can be compared and measured.
