Resumen

GARCIA-ELORRIAGA, Guadalupe et al. Microbiology of bronchoalveolar lavage in infants with bacterial community-acquired pneumonia with poor outcome. Bol. Med. Hosp. Infant. Mex. [online]. 2015, vol.72, n.5, pp.307-312. ISSN 1665-1146.  http://dx.doi.org/10.1016/j.bmhimx.2015.09.004.

Background:

Community-acquired pneumonia (CAP) is one of the most common infectious causes of morbidity and mortality in children <5 years of age. The aim of the study was to clarify the bacterial etiologic diagnosis in infants with CAP.

Methods:

A prospective, cross-sectional and descriptive study in patients 6 months to 2 years 11 months of age with CAP with poor outcome was conducted. Patients were admitted to the Pediatric Pneumology Service and underwent bronchoscopy with bronchoalveolar lavage (BAL), taking appropriate measures during the procedure to limit the risk of contamination.

Results:

Aerobic bacteria isolated were Moraxella sp. 23%, Streptococcus mitis 23%, Streptococcus pneumoniae 18%, Haemophilus influenzae 12%, Streptococcus oralis 12%, and Streptococcus salivarius 12%.

Conclusions:

In contrast to other reports, we found Moraxella sp. to be a major bacterial pathogen, possibly because of improved detection with bronchoscopy plus BAL.
