Bacteriological profile of lower respiratory tract infections in patients admitted to the pulmonology ifirmary at a Tertiary Hospital for Reference in Lung Diseases in the State of Pernambuco

Abstract

Introduction: respiratory tract infection is responsible for high morbidity and mortality, and lead to frequent use of
antibiotics. It is important to know the bacteriological profile according to the evaluated base location and condition of the patient,
since, on many occasions, the treatment of these infections is initiated empirically. Objective: It is to identify the bacteriological profile
of sputum cultures and bronchoalveolar lavage and verify the underlying lung disease of hospitalized patients in pulmonology ward.
Methods: The study consisted of a retrospective series of cases, where the cultures of sputum and / or bronchoalveolar lavage fluid of 70
patients were analyzed. Results: The most prevalent pathogens in sputum cultures were Pseudomonas sp. and Klebsiella sp.,
respectively, in 17 (24%) and 15 (21%) patients. There was no predominance of any pathogen in the cultures of bronchoalveolar lavage.
Bronchiectasis was the most prevalent pulmonary disease with pulmonary tuberculosis after-effects, there was a significant
relationship between their presence and the infection by Pseudomonas sp. (P <0.05). Conclusion: The finding of Pseudomonas sp. as
the most common bacteria, particularly in patients with bronchiectasis by pulmonary tuberculosis after-effects, as well as the finding of
Klebsiella sp. as the second most common pathogen, although not associated with any underlying lung disease, may assist in the choice
of empirical therapy of patients admitted to the pulmonology ward of the Hospital.
