7日間にわたって(日別試験を繰り返した)PHMBを含む本発明の発泡体被覆材試料について3重法で抗菌活性を評価した。PHMBを含まない発泡体被覆材を陽性対照として用いた。アメリカンタイプカルチャーコレクション(ATCC)#27853のPseudomonas aeruginosa(Pseudomonas aeruginosa)、ATCC#12228のStaphylococcus epidermidis(Staphylococcus epidermidis)、ATCC#25923のStaphylococcus auereus(Staphylococcus aureus)、ATCC#25922のEscherichia coli(Escherichia coli)、ATCC#29212のEnterococcus faecalis(Enterococcus faecalis)およびATCC#10231のCandida albicans(Candida albicans)の6つの一般的な創傷病原体に対して別々に被覆材を試験した。各試験生物の懸濁液を調製した。直径が25mmの被覆材試料をトリプシン大豆寒天(TSA)床上に置いて水分および構造を保持した(被覆材を反らせない)。被覆材試料に体積0.5mlの試験微生物または標的微生物の懸濁液(6‐log cfu/ml)を接種し、37℃でインキュベーションした。接種後24時間のインキュベーションの後、3つの被覆材試料の1組を取り出し、15mlのDey−Engley (DE)中和ブロス中でボーテクス混合した。各試験管から1.0mlの試料を取り出し、DEブロスを希釈剤として用いて標準逐次希釈液を調製した。逐次希釈プレートを調製し、37℃で24時間からインキュベーションし、その時点から全生菌数の定量化プレート計数を実行した。試験試料と対照試料との生菌数を比較し、微生物の数のlog減少によって効力を評価し、記録した。表2および作図中に報告する値は、毎日微生物活性を分析した3つの試料の計数値の平均を表す。残っている被覆材試料に試験生物を再接種し、24時間インキュベーションし、次の組の3つの被覆材試料を引き上げ、ボーテクス混合し、上記で説明したように計数した。この手順を7日間繰り返した。
PHMBを含む本発明の発泡材料の25mmの円板、およびPHMBを含まない本発明の発泡体から作られた円板を無菌法で調製した。適切にラベルを貼ったキャップ付きの滅菌50ml試験管中に被覆材を無菌法によって移した。アッセイを3重法で7日間行った。
