The invention relates to a method and means for detecting microbial pathogens in a sample body fluid which is suspected to contain antimicrobial factors by incorporating in the sample fluid an effective amount of an antimicrobial factor deactivating system which is noncidal to the microbial pathogens.
The antimicrobial deactivating system includes aminoglycoside blocking agents, such as sodium polyanetholsulfonate and sodium amylosulfate; penicillin and cephalosporin deactivating agents, such as thioglycolate, glutathione, N-acetyl-cysteine and cysteine; a sulfa compound deactivating agent, such as p-aminobenzoic acid and enzymes which are specific to antibiotics.
The antimicrobial factor deactivating system may also contain other compounds depending on the usage of the systems, for example lysing agents and anticoagulants.
本发明涉及一种检测疑似含有抗菌因子的样本体液中微生物病原体的方法和手段,方法是在样本体液中加入有效量的抗菌因子失活系统,该系统对微生物病原体无杀灭作用。
抗菌剂失活系统包括氨基糖苷类阻断剂,如聚乙醇磺酸钠和氨基磺酸钠;青霉素和头孢菌素类失活剂,如硫代乙酸盐、谷胱甘肽、N-乙酰半胱氨酸和半胱氨酸;磺胺类化合物失活剂,如对氨基苯甲酸和抗生素特异性酶。
根据系统的用途,抗菌因子失活系统还可能含有其他化合物,例如裂解剂和抗凝剂。
