Infection occurs throughout the year, often resulting in a small-scale epidemic. In recent years, MP infection shows a trend of increasing year by year [1]. MP not only affects the respiratory tract, but also can lead to multiple system, multiple organ damage, its pathogenesis and more think that the formation of immune complexes, is now our hospital pediatric January 2007 to May 2008 admitted 50 cases of MP infection Children’s clinical data are as follows.
