Incidence of lower respiratory tract infections caused by Mycoplasma, Chlamydia and Legionella: an Italian Multicenter Survey.

Author information

Institute of Microbiology, University of Genoa, Chieti, Italy.


A collaborative retrospective study based on serologic diagnosis was conducted to assess the etiological role sustained by privileged pathogens in Italy. The results obtained indicate the Mycoplasma, Chlamydia and Legionella are important etiologic agents of lower respiratory tract infections in Italy since they account for about 31% of the cases taken into consideration in this survey. We found a high incidence of M. pneumoniae (12.3%), C. pneumoniae (10.5%) and L. pneumophila (8.3%). These results are in line with similar figures reported in the recent literature. While the data gathered in our survey do not allow us to clarify the nature of the agents involved in the etiology of the majority (70%) of the respiratory infections occurring in Italy, it seems safe to assume that after Streptococcus pneumoniae and Haemophilus influenzae, the privileged pathogens represent the most common cause of lower respiratory tract infections.
