Antibody levels toMycoplasma pneumoniaein sera collected from healthy blood donors of Wellington, New Zealand, during 1976–80

Abstract
SUMMARY: The sera of healthy blood donors from the Wellington area of New Zealand, collected between 1976 and 1980, were analysed by the complement fixation test for antibody toMycoplasma pneumoniae. A high prevalence of antibody to this organism was demonstrated and the occurrence of anM. pneumoniaeepidemic in New Zealand within the survey period was shown to be reflected i the immune status of this healthy adult population. This would suggest that during an epidemic many people within the Wellington community may haveM. pneumoniaeinfections involving littl overt illness.
