The spectrum of community-acquired pneumonia (CAP) due to Chlamydophila psittaci ranges from mild, self-limited CAP, to acute respiratory failure. We performed a retrospective study of 13 consecutive patients with CAP due to C. psittaci and 51 patients with legionellosis admitted in one intensive care unit (ICU) (1993–2011). As compared to patients with legionellosis, patients with psittacosis were younger (median age 48 [38–59] vs. 60 [50–71] years, p  = 0.007), less frequently smokers (38 vs. 79 %, p
