Number of laboratory reports per year from January 1995 to June 2015 separated by detection methodology. National reporting categories included are: antibody detection and antibody-detection rising titre. A rising titre is defined as a four-fold increase in detectable anti-Mycoplasma pneumoniae antibody level (methods not specified). Other indicates specimens for which M. pneumoniae infection was determined using antigen detection (method not specified), microscopy and unknown categories. Culture indicates cases from which specimens yielded isolates of M. pneumoniae and genomic detection those for which DNA of M. pneumoniae was detected by PCR.
