| In this explorative study, M. pneumoniae will be quantified in nose- and throat swabs/aspirates of children aged 0-16 years with mild to severe symptoms of respiratory tract infection, and in a control group consisting of children without respiratory tract infection. The quantity of M. pneumoniae (in copies/ml or copies/swab) will be related to clinical disease in order to differentiate asymptomatic carriership from infection. To investigate the role of co-colonization or -infection, the presence of other bacteria or viruses in the respiratory tract will be analyzed as well. To study the age distribution in relation to M. pneumoniae infection, a precalculated number of patients of either = 5 years of age will be included. Genotyping of M. pneumoniae will be performed, and related to severity of disease and/or colonization. Prevalence of colonization and/or infection with M. pneumoniae will be calculated. | — |
