Assess the correlation between Xpert Carba-R detection of carbapenemase gene types in bronchoalveolar lavage samples and rectal swab samples from non-colonized CRKP patients with lower respiratory tract infections, and evaluate the relationship between first-time lower respiratory tract infections and intestinal colonization of CRKP.

Inclusion Criteria:
* Aged 18 years and above
* CRKP is cultured from lower respiratory tract specimens in 15 days
* Lower respiratory tract infection based on at least two of the followings: abnormal temperature (body temperature greater than 38.5°C or less than 36.5°C), leucocyte count abnormality (leucocyte count greater than 10\*10\^9/L or less than 4\*10\^9/L), and the presence of purulent tracheal secretions.
Exclusion Criteria:
* There are other bacteria that can produce carbapenemases exist in lower respiratory tract specimens
* Infected with CRE before
Primary outcome measure(s)
The detection of the carbapenemase gene types produced by Klebsiella pneumoniae in rectal swabs and BALF by Xpert Carba-R — Up to 2 weeks after each enrollment The investigators use the Xpert Carba-R to detect the carbapenemase gene types produced by Klebsiella pneumoniae in rectal swabs and bronchoalveolar lavage fluid (BALF) . The investigators will compare the consistency of results between the two specimens.
