A cross-sectional study of isolates from sputum samples from bacterial pneumonia patients in Trinidad

Abstract

We determined the frequency of Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus, and Gram-negative enteric bacteria (GNEB) in pneumonia patients, determined the antibiograms of these pathogens, and investigated the relationship between pneumonia and selected risk factors. Sputum and demographic data were collected from 124 pneumonia patients. Sputum was cultured for S. aureus, GNEB, H. influenzae and S. pneumoniae. The disc diffusion method was used to determine resistance to eight antimicrobial agents. Among the 124 sputum samples, eight (6.5%) were positive for S. aureus, 15 (12.1%) for GNEB, two (1.6%) for S. pneumoniae and one (0.8%) for H. influenzae. Hospitals, gender, ethnicity, co-morbidities and symptoms did not significantly (p > 0.05; chi2) affect the prevalence of these bacteria. GNEB infection was most prevalent (47%) in patients over 70 years old. Gentamicin and levofloxacin were the most effective against these bacteria.

Bacterial Etiology of Acquired Community Pneumonia Among Yemeni Patients Whose Diagnosed Clinically as A Pulmonary Tuberculosis Patients

“…Our results were different from the result reported from Finland and Spain in which arthritis, diabetes mellitus (DM), liver disease or renal insufficiency found to be significant risk factors of contracting bacterial pneumonia (Lim, et al, 2001;Nagalingam, at al., 2005;and Arancibia, et al, 2002).…”

“…Entre las bacterias Gram positivas cabe resaltar como streptococo pneumonie solo se presentó en proporción menor al stafilococcus aureus. Estos resultados son diferentes a lo reportado en otro estudio en el que encontraron una prevalencia entre el 30 y el 50% (16) como responsable de neumonías y bacteriemia.…”

Respiratory Infections

“…(GNEB) infection was prevalent (47%) over 70 years old. Gentamicin and levofloxacin were the most effective against these bacteria (Nagalingam et al, 2005) Smoking is a risk factor for a number of pulmonary infections, probably because of its adverse effects on respiratory defences. It is associated with increased morbidity and mortality from pneumonia and influenza, as well as more days lost from work from lower respiratory infections.…”
