Antimicrobial resistance in sputum of patients with lower respiratory infections

Abstract

A study was performed to identify the germs present in the sputum samples and determine antimicrobial resistance in patients with symptoms and signs of lower respiratory infections, treated at the General Teaching Hospital “Dr. Agostinho Neto" of Guantánamo in 2013. The universe of study was 949 sputum samples for performing culture. Antimicrobial resistance was determined by standard clinical methods at Laboratory Standard Institute (CLSI). It was found predominance in sputum from admission rooms. The 29.2 % of    sputum tested positive at bacteriological culture, 4.2% in AFB or BAR sputum and 55.6 % in mycological culture. Gram-negative bacteria constituted the majority of isolates in patients with lower respiratory tract infections. The hemolytic Streptococcus was the gram-positive germ more identified. A high rate of resistance was obtained to ampicillin, ceftriaxone, cefepime, in most                
isolated bacteria.
