So, with Klebsiella, urease makes urea dissociate into carbon dioxide and ammonia.

肺炎克雷伯杆菌产生的脲酶使得尿素解成二氧化碳和氨。

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、痰或者尿离出肺炎克雷伯杆菌，即可诊断。

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病（如糖尿病）的人群和应用心静脉导管、气管内插管或者导尿管的人群，引医院获得性感染。

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毒力，可以攻击宿主细胞，并逃避免疫。

It's a multidrug resistant bacteria, and it can be treated with cephalosporins, aminoglycosides, fluoroquinolones, and carbapenems in case of beta-lactamase production; only with carbapenems in case of ESBL production; and with colistin, tigecycline or fosfomycin in case of carbapenemases production.

肺炎克雷伯杆菌也是一多重耐药菌，如果产生β-内酰胺酶，可以用头孢菌素、氨基糖苷类、氟喹诺酮类以及碳青霉烯类药物治疗；如果产生ESBL，可以只应用碳青霉烯类进行治疗；如果产生碳青霉烯酶，则应用多粘菌素、替加环素或磷霉素进行治疗。

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多重耐药菌，它能产生多解抗生素的酶。

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，将尿素解成二氧化碳和氨。

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。
