Comparative frequency of identification of pathogens in elderly and young patients in European studies that have contemporaneously applied the same methodology to both groups. Results of four studies totalling 2193 patients (566 elderly patients defined as >60, >65 and >79 years) [II] [II] [II] [II] For each organism, the frequency (±95% confidence intervals) in elderly patients is shown in the left bar and in young patients in the right bar. Sp, Streptococcus pneumoniae; Hi, Haemophilus influenzae; Lp, Legionella spp; Sa, Staphylococcus aureus; Mcat, Moraxella catarrhalis; GNEB, Gram-negative enteric bacilli; Mp, Mycoplasma pneumoniae; Cp, Chlamydophila pneumoniae; Cpsi, Chlamydophila psittaci; Cb, Coxiella burnetii; allV, viruses; Flu, influenza viruses; oth, other organisms; none, no pathogen identified.
