The vast majority of these are caused by the streptococcus pneumoniae.

其绝大部分是由肺炎链球菌引起的。

In adults, bacterial causes include streptococcus pneumoniae, haemophilus influenzae, and staphylococcus aureus.

Bacteria that thrive in a low pH, like mutans streptococci and Lactobacillus, begin to dominate.

适宜在低pH值生存的细菌，例如变形链球菌和乳酸杆菌，将会占据主导地位。

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

我们可以利用这一特来区分腐生葡萄球菌和其他革兰氏阳球菌，如链球菌和肠球菌这一类过氧化氢酶阴的细菌。

The major genera with the largest representation in the oral cavities include: streptococcus, prevotella, haemophilus, rothia, veillonella, neisseria, fusobacterium, and porphyromonas.

口腔的微生物主要包括以下几个大属：链球菌属、普氏菌属、嗜血杆菌属、罗氏菌属、韦荣氏球菌属、奈瑟氏菌属、梭杆菌属与卟啉单胞菌属。

Normally, there's a layer called the pellicle that covers the tooth, and bacteria in the mouth, like viridans group streptococci, settle on that pellicle layer.

正常情况下，齿被薄膜包裹，口腔的细菌，例如草绿色链球菌，定植在这层薄膜上。

Streptococci is one of the most common bacteria found in our mouth and it's normally not harmful until it metabolizes sugar or protein from food debris.

链球菌是我们口腔最常见的细菌之一，通常无害，直到它从食物残渣代谢糖或蛋白质。

That environment favors bacteria like mutans streptococci and Lactobacillus, which demineralize enamel and the dentin beneath it, and if untreated, it can eventually result in a cavitated caries lesion.

酸下的优势菌例如变形链球菌和乳酸杆菌，可以食釉质及其下层的本质脱矿，如果不加以治疗，最终会形成空洞型龋齿。

His sore throat was actually a very bad infection caused by a certain kind of bacteria called " streptococcus, " or more commonly " strep (strep) throat."

他的喉咙痛实际上是一种非常严重的感染， 由一种叫做“链球菌” 或更常见的“链球菌（链球菌）咽喉炎” 的细菌引起。

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，因为红葡萄酒含有一种有机酸混合物可以有效抑制导龋齿的口腔链球菌属以及导咽炎的化脓链球菌。
