Pneumonia, bronchitis, pharyngitis, sinusitis

The spectrum of clinical symptoms caused by Chlamydophila pneumoniae includes pharyngitis, sinusitis, bronchitis and atypical pneumonias (approximately 10 % of all pneumonias). The frequency of the mainly mild courses of illness increases during childhood and reaches its peak in young adults. Endemic infection in adults is 25 – 45 %. Human-to-human transmission through aerosols and smear infection. Epidemic increase approximately every 6 – 7 years with a duration of 2 – 3 years. Outbreak often localized. Species-specific antibodies against Chlamydophila pneumoniae only increase slowly after infection; it may take up to 3 weeks until IgA antibodies are detectable and up to 6 weeks for IgG antibodies to be seen.
