Klebsiella pneumoniae can normally colonize the oropharynx and the gastrointestinal tract.

正常情况下，肺炎克雷伯杆菌是人体口咽部与胃肠道的定植菌。

Klebsiella pneumoniae is a multidrug resistant bacterium, which produces different enzymes that break down the structure of antibiotics.

肺炎克雷伯杆菌是一种多重耐药菌，它能产生多种分解抗生素的酶。

Finally, Klebsiella pneumoniae grows well on MacConkey agar, which is a medium that contains a pH sensitive dye and lactose.

最后，肺炎克雷伯杆菌可以在含有pH指示剂的MacConkey琼脂培养基上良好地生长。

First, Klebsiella pneumoniae is encapsulated, which means it's covered by a polysaccharide layer called a capsule.

首先，它被多糖成分的荚膜包裹。

For diagnosis, Klebsiella pneumoniae can be isolated in cultures from blood, sputum, or urine depending on the type of infection.

根据感染类型，从血液、痰液或者尿液中分离出肺炎克雷伯杆菌，即可诊断。

Alright, now Klebsiella pneumoniae is urease positive, which means it can produce an enzyme called urease that dissociates urea into carbon dioxide and ammonia.

肺炎克雷伯杆菌脲酶阳性，可以产生脲酶，将尿素分解成二氧化碳和氨。

Now, Klebsiella pneumoniae has a number of virulence factors that are like assault weaponry that help it attack and destroy the host cells and evade the immune system.

肺炎克雷伯杆菌具有多种毒力，可以攻击宿主细胞，并逃避免疫。

Now, Klebsiella pneumoniae can cause various hospital-acquired infections in people with underlying illnesses (like diabetes) and in the presence of foreign devices like central venous catheters, endotracheal tubes, or urinary catheters.

同时，肺炎克雷伯杆菌容易在患有基础疾病（如糖尿病）的人群和应用中心静脉导管、气管内插管或者导尿管的人群中，引起各种医院获得性感染。
