- Abstract
Mycoplasma pneumoniae (M. pneumoniae) isolates can be classified into two major genetic groups, P1 type 1 (MP1) and P1 type 2 (MP2), based on the DNA sequence of the P1 adhesion protein gene. The aim of our study was to determine if M. pneumoniae P1 genotype is associated with disease manifestation and severity of acute M. pneumoniae infection. We compared epidemiological and clinical data of children infected with either MP1 or MP2. In addition, we separately analysed data of patients presenting with individual manifestations of M. pneumoniae infection. Data of 356 patients infected with MP1 were compared with those of 126 patients infected with MP2. MP2-infected children presented with higher median baseline C-reactive protein levels and were admitted to the hospital more often. The distribution of P1 genotype varied among groups of patients with different manifestations of M. pneumoniae infection. MP2 was more common than MP1 among patients with neurological and cardiovascular manifestations, whereas MP1 was more prevalent in other manifestations. The results from our large cohort indicate that the two P1 subtypes may have different pathogenic potential and that infections with MP2 strains could be more virulent than those with MP1 strains.
