Description
(1)酵素基質、酸化還元試薬および亜テルル酸塩を含有することを特徴とするカンジダ鑑別用発色培地。
(2)亜テルル酸塩が亜テルル酸カリウムおよび/または亜テルル酸ナトリウムである(1)記載のカンジダ鑑別用発色培地。
(3)亜テルル酸塩の含有量が0.0005〜0.015g/Lの範囲である(1)または(2)記載のカンジダ鑑別用発色培地。
(4)酵素基質が5−ブロモ−4−クロロ−3−インドリルホスフェート.2Na(以下、x−phos.2Naという)および/または5−ブロモ−4−クロロ−3−インドリル−N−アセチル−β−D−ガラクトサミニド(以下、x−galactosaminideという)である(1)〜(3)のいずれか1項に記載のカンジダ鑑別用発色培地。
(5)酵素基質の含有量が0.01〜0.1g/Lの範囲である(1)〜(4)のいずれか1項に記載のカンジダ鑑別用発色培地。
(6)酸化還元試薬がテトラゾリウム塩である(1)〜(5)のいずれか1項に記載のカンジダ鑑別用発色培地。
(7)テトラゾリウム塩がテトラゾリウムバイオレット(以下、TTVという)および/またはテトラゾリウムブルー(以下、TTBという)である(6)記載のカンジダ鑑別用発色培地。
(8)酸化還元試薬の含有量が0.001〜0.01g/Lの範囲である(1)〜(7)のいずれか1項に記載のカンジダ鑑別用発色培地。
(9)培地1Lあたり、ペプトン10〜30g、酵母エキス1〜10g 、白糖1〜20g、ブドウ糖1〜10g、TTV0.001〜0.01g、x−phos.2Na0.01〜0.1g、亜テルル酸カリウム0.0005〜0.015gおよび寒天3〜20gを含有する(1)〜(8)のいずれか1項に記載のカンジダ鑑別用発色培地。
本発明のカンジダ鑑別用発色培地の特徴は、培地中に酵素基質、酸化還元試薬および亜テルル酸塩を含有させることにある。
表1に示した培地成分51.3gを秤量し、1000mLの精製水に溶解した。溶解後、pHを6.0±0.2に調整し、121℃で高圧滅菌した。冷却後、表2に示した所定量でx−phos.2Na、TTVおよび亜テルル酸カリウムを濾過滅菌して加えた後、20mLずつシャーレに分注して固形化した。亜テルル酸カリウムを添加していないものを比較例とした。
