Description

本発明は、レジオネラ除菌剤に関するものである。   The present invention relates to a Legionella sanitizer.

近年、温泉や風呂において、温水を循環させて使用することが一般的になってきた。それにつれ、公衆浴場、薬湯風呂といった、複数の人間が利用する水循環型施設において、風呂の循環水のレジオネラ、大腸菌などによるバイオハザードが深刻な問題となっている。また、空調や生産プロセス用の熱交換器に使用されているクーリングタワーでも、同様に冷却水のバイオハザード現象が報告されており、レジオネラに汚染されたエアロゾルを吸入することにより、人体に感染することが知られている。
In recent years, it has become common to circulate hot water in hot springs and baths. As a result, biohazard caused by Legionella, Escherichia coli, etc., which is circulating water in baths, has become a serious problem in water circulation facilities such as public baths and medicinal baths. Similarly, cooling tower biohazard phenomena have been reported in cooling towers used in heat exchangers for air conditioning and production processes, and infecting human bodies by inhaling aerosols contaminated by Legionella. It has been known.

レジオネラは0.3〜0.9×2.0〜20.0μmの好気性グラム陰性桿菌で、その発育至適温度が35−36℃と循環水や冷却水などの温度と合致している。また、藻類やアメーバ、従属栄養細菌などから栄養源を得る共生細菌であり、上述したような微生物類の繁殖しやすい循環水や冷却水においては絶好の生育環境となる。その症状は、肺炎と類似した性質を示し、レジオネラ肺炎、ポンティアック熱の2種類が知られており、場合によっては死をもたらす危険性もある。
Legionella is an aerobic gram-negative bacilli of 0.3-0.9 × 2.0-20.0 μm, and its optimum growth temperature is 35-36 ° C., which is consistent with the temperature of circulating water and cooling water. Moreover, it is a symbiotic bacterium that obtains a nutrient source from algae, amoeba, heterotrophic bacteria, and the like, and is a perfect growth environment in circulating water and cooling water in which microorganisms are easy to propagate. The symptoms are similar to those of pneumonia, and two types are known, Legionella pneumonia and Pontiac fever, and there is a risk of death in some cases.

従来、レジオネラの生育、増殖防止に、(A)pH調整剤やスライムコントロール剤、除菌剤の添加により、レジオネラの栄養物を取り除き、レジオネラの生育可能な環境を変化させ、間接的にレジオネラの増殖を防止する方法、(B)除菌剤を添加してレジオネラ自身を死滅させる方法、(C)過酸化水素、塩素等の化学洗浄剤で定期的に洗浄を行い、レジオネラの発生を防止する方法、などの対策がとられている。
Conventionally, to prevent the growth and proliferation of Legionella, (A) By adding a pH adjuster, slime control agent, and disinfectant, Legionella's nutrients are removed, Legionella's growth environment is changed, and Legionella's growth environment is changed indirectly. Method of preventing growth, (B) Method of killing Legionella itself by adding a disinfectant, (C) Periodic cleaning with chemical cleaning agents such as hydrogen peroxide and chlorine to prevent Legionella from occurring Measures such as methods are taken.

上記の中で(A)の方法は、積極的にレジオネラを排除するわけではなく、すでにレジオネラの発生した環境への適用は難しい。また、(C)の方法では、投与した時点で一時的に微生物の発生を防止することはできるが、その抗微生物作用に持続性が伴わないため、再び微生物に汚染されることがある。この場合、微生物が発生するたびに化学洗浄剤を投与することになり、手間とコストの問題や、化学洗浄剤が人体などに与える影響も大きくなる。やはり、(B)による解決方法が最も効果的で確実な手法と考えられている。
を吸入することにより、人体に感染することが知られている。

Among the above, the method (A) does not actively eliminate Legionella, and it is difficult to apply it to an environment in which Legionella has already occurred. In addition, in the method (C), the generation of microorganisms can be temporarily prevented at the time of administration, but the antimicrobial action is not accompanied by persistence, and may be contaminated with microorganisms again. In this case, the chemical cleaning agent is administered every time microorganisms are generated, and the problem of labor and cost and the influence of the chemical cleaning agent on the human body and the like are increased. After all, the solution by (B) is considered the most effective and reliable method.
It is known to infect the human body by inhaling.

レジオネラに有効とされている除菌剤として、イソチアゾリン系化合物(特開平10−218710号公報)、ブロノポール系化合物などが挙げられるが、これらの薬剤は、毒性やpH、温度感受性、化学安定性、生分解性、適合性などの点で制限があり、すべてに対応可能というわけではない。例えば、上記化合物の場合、臭気や金属腐食を引き起こす問題がある。また、微生物だけでなく人体にも影響を与える可能性があるため、至適使用量を添加することができず、その結果、微生物や藻類の発生を十分に抑えることがないという欠点があった。
特開平10−218710号公報
Examples of the disinfectant effective for Legionella include isothiazoline compounds (Japanese Patent Laid-Open No. 10-218710), bronopol compounds, etc. These drugs are toxic, pH, temperature sensitive, chemical stability, There are limitations in terms of biodegradability, compatibility, etc., and not all can be accommodated. For example, in the case of the said compound, there exists a problem which causes an odor and metal corrosion. In addition, since there is a possibility of affecting not only microorganisms but also the human body, the optimum amount of use cannot be added, and as a result, there is a disadvantage that generation of microorganisms and algae cannot be sufficiently suppressed. .

For example, the amount left by heating in a 100 ° C. oven for 60 minutes Is divided by the amount before heating. Therefore, when the Sasa extract is solid, it is diluted with water, and when the Sasa extract is a dilute solution, it is concentrated to adjust the heating residue to 40 to 60% by weight. Since sugars serve as a nutrient source for Legionella, it is preferable that the content of sugars is limited. The Sasa extract used in the present invention preferably has a small amount of saccharides and a large presence index of sterilizing compounds such as phenylpropanoids.
In addition, phenylpropanoid, acetic acid, formic acid, and 3-hydroxypyridine can be quantified by liquid chromatography, gas chromatography, or the like. Saccharides can be quantified by ion chromatography.

細菌類への殺菌試験は、次のように行った。試験菌は、α寒天培地に接種して35℃で4日間培養後の発育集落を抜き取り、滅菌蒸留水に懸濁後、約105CFU/ml(CFU:Colony Forming Unit(集落形成単位)の略。1mlの試料から50個の集落が検出された場合、50 CFU/mlと 表示する。)濃度に調整して試験菌液とした。この試験菌液1mLをササ抽出物エキス(0%、0.1%、1%、5%)溶液100mlに接種し、これを試験溶液として試験菌数を約103CFU/ml濃度とし、常温下(25℃孵卵器内)で0時間、1時間、3時間、24時間の暴露を行なった。
所定時間経過後の試験液を採取して、滅菌生理食塩水で10倍段階希釈を行い、その各段階の0.1mlをα寒天培地表面上に塗布し、35℃で4日間培養を行い、培地上に発育した試験菌集落数を算定した。
その結果を表1に示した。



The sterilization test for bacteria was performed as follows. The test bacteria were inoculated into an α agar medium, and the growth colonies after culturing at 35 ° C. for 4 days were extracted, suspended in sterilized distilled water, and about 10 5 CFU / ml (CFU: Colony Forming Unit). Abbreviation: When 50 colonies are detected from a 1 ml sample, it is displayed as 50 CFU / ml. 1 ml of this test bacterial solution is inoculated into 100 ml of Sasa extract extract (0%, 0.1%, 1%, 5%), and this is used as a test solution with a test bacterial count of about 10 3 CFU / ml. Under exposure (in a 25 ° C. incubator), exposure was performed for 0 hour, 1 hour, 3 hours, and 24 hours.
Collect the test solution after the lapse of a predetermined time, perform 10-fold serial dilution with sterilized physiological saline, apply 0.1 ml of each step on the surface of the α agar medium, and culture at 35 ° C. for 4 days. The number of test colonies grown on the medium was calculated.
The results are shown in Table 1.

表1に示した結果は、浴槽水中でのレジオネラ属菌数を想定し、試験溶液中での初発菌数をおおよそ
103CFU/mlと設定した。本試験での試験溶液0hr後の試験菌数は5.8〜6.6×103CFU/mlであった。
もっとも高濃度のササ抽出物溶液(5%)では、1時間後に検出限界未満値に減少した。また、低濃度のササ抽出物溶液(0.1%及び1%)についても時間に比例して試験菌の減少を認めた。以上の結果が示すように、本発明のササ抽出物は、レジオネラに対して微量濃度で効果を示すことが確認された。
The results shown in Table 1 assume the number of Legionella in the bath water, and set the initial number of bacteria in the test solution to approximately 10 3 CFU / ml. The number of test bacteria after 0 hr of the test solution in this test was 5.8 to 6.6 × 10 3 CFU / ml.
The highest concentration of Sasa extract solution (5%) decreased to a value below the detection limit after 1 hour. In addition, a decrease in the test bacteria was observed in proportion to time for the low concentration Sasa extract solution (0.1% and 1%). As the above result showed, it was confirmed that the Sasa extract of this invention shows an effect with respect to Legionella at a trace concentration.

上記結果を見る限り、本発明のレジオネラ除菌剤は、従来の除菌剤で解決できなかった種々の問題をクリアする、安全性の高い優れた除菌剤であることを証明するものである。
