We can use this to differentiate Staph saprophyticus from other gram positive cocci, like streptococci and enterococci, which are catalase negative.

You might have a lobar pneumonia, for example, and they could give you an antiserum, an injection of rabid antibodies to the bacterium streptococcus, if the intern sub-typed it correctly.

比如说，你患有大叶性肺炎，医生可以对你进行抗血清治疗，为你注射狂犬病抗体以此对抗链球菌，前提是实习医生分类正确。

However, moderate consumption of red wine may enhance oral health, because it contains a mixture of organic acids that are active against oral streptococci responsible for caries development and streptococcus pyogenes responsible for pharyngitis.

不过，适量饮用红葡萄酒可能会增进口腔健康，因为红葡萄酒中有一种有机酸混合可以有效抑制导致龋齿的口腔链球菌属以及导致咽炎的化脓性链球菌。
