Abstract

The inhibition of Staphylococcus aureus growth and enterotoxin and thermonuclease production by various concentrations of garlic (Allium sativum) was studied in BHI broth. The growth of Staph. aureus was inhibited by dehydrated garlic at levels of 1.5% (w/v) and over. Enterotoxins A, B and C1 were only detectable in broth containing < 1% of garlic while enterotoxin D was produced at a level of 2%. Garlic also inhibited thermonuclease (TNAse) production, complete inhibition being observed at levels > or = 1.5%. TNAse was not always detected when enterotoxin was present.

脱水大蒜对葡萄球菌生长、肠毒素(A-D)和热酶合成的影响。
研究了不同浓度大蒜对BHI肉汤中金黄色葡萄球菌生长、肠毒素和热酶产生的抑制作用。葡萄球菌的生长。脱水大蒜对金黄色葡萄球菌有1.5% (w/v)及以上的抑制作用。肠毒素A、B和C1仅在大蒜含量< 1%的肉汤中检测到,而肠毒素D在大蒜含量为2%的肉汤中产生。大蒜还抑制了热核酸酶(TNAse)的产生,在含量>或= 1.5%时观察到完全抑制。当肠毒素存在时,TNAse并不总是被检测到。
