ABSTRACT
Objective To explore the non-bacteria etiology of pneumonia in children under 12 years old in southwest Shanghai,and investigate clinical characteristic of pneumonia caused by different pathogens.Methods The serum of 187 children with pneumonia from July 2002 to December 2004 in hospital were investigated for respiratory syncytial virus(RSV),adenovirus 3 influenza viruses(IFV) A and B,parainfluenza viruses(PIV)type 1,2,3,4 and coxsackievirus A 1.7,echovirus 7 by employing the indirect immunofluorescence assay(IFA)for the identification of nearly 8 different viruses,and 3 different enteroviruses.Based on the principle that sensitized particles were agglutinated by the pressence of antibodies to mycoplasma pneumonia in human serum.Results Examination for 8 kinds of conventional respiratory virus infected,a total of 90 positive results in 187 cases(48.13%),Firstly was RSV(19.79%),(secondly) was IFV B(16.58%).Out of these 1084 children,154 cases(14.21%)showed positive in anti-mycoplasma pneumonia.Conclusions RSV is still the leading cause of pneumonia in children during winter and spring in southwest in Shanghai.Mycoplasma pneumonia is having been the major pathogens of the school-aged children with pneumonia.
