Introduction:

Community-acquired pneumonia (CAP) is a major health problem worldwide and in Cuba. Its incidence and lethality make this desease a real challenge for healthcare services.

Objective:

to identify the incidence of Klebsiella pneumoniae isolated from sputum samples in patients with community-acquired pneumonia.

Method:

a descriptive and cross-sectional study was carried out in the microbiology laboratory of the Provincial Hygiene, Epidemiology and Microbiology Center of Guantanamo from January to June 2016. The universe of study consisted of 88 patients. The laboratory procedure proposed by Expósito et al.

Results:

72 samples of productive sputum were identified, of which 56 samples were positive for bacterial culture, Klebsiella pneumoniae was isolated in 34, which resulted in the study sample, showing marked resistance to amoxicillin and ceftriaxone. This microorganism was framed as a pathogen that emerged as responsible for the etiology of respiratory infections acquired in the community.

Conclusions:

Klebsiella pneumoniae, due to its frequency of isolation, due to its pathogenic and resistance mechanisms, is considered an opportunistic pathogen that emerges as responsible for the etiology of respiratory infections acquired in the community.
