摘要

目的 调查泸州地区2011年小儿肺炎感染病原谱.方法 选取2011年1-12月泸州医学院附属医院儿内科住院治疗的小儿肺炎1500例,用间接免疫荧光法检测血清呼吸道病毒、支原体、衣原体IgM抗体,痰培养检测细菌.结果 1500例患儿中,阳性总检出率为720例(48.00％),其中病毒感染324例(21.60％),支原体感染102例(6.80％),衣原体感染85例(5.60％),嗜肺军团菌感染15例(1.00％),细菌感染132例(8.80％),白色念珠菌感染12例(0.90％),混合感染62例(8.50％)；其中呼吸道合胞病毒(RSV)感染、白色念珠菌、混合感染均易发生在小于3岁的婴幼儿.结论 泸州地区的小儿肺炎中,其主要的病原体为病毒,其次是支原体、细菌；而年龄较小(小于3岁)的婴幼儿更易出现RSV病毒、细菌、白色念珠菌和混合感染.%Objective To investigate the etiology of pediatric pneumonia in Luzhou area in 2011.Methods 1500 children with pneumonia admitted in Department of Pediatric Internal Medicine, the Affiliated Hospital of Luzhou Medical College in 2011 were investigated.The serum IgM antibodies of respiratory virus, mycoplasma and chlamydia were detected by indirect immunofluorescence, bacteria was detected by sputum culture.Results The total positive detection rate was 720 cases (48.00%), in which the virus positive was 324 cases (21.60%), mycoplasma 102 cases (6.80%), chlamy dia in 85 cases (5.60%), legionella pneumophila 15 cases (1.00%), bacterial 132 cases (8.80%), Candida albicans 12 cases (0.90%), mixed infection 62 cases (8.50%).The infection of RSV, Candida albicans and mixed infection occurred much more in children less than 3 years old.Conclusion The main pathogens caused pediatric pneumonia in Luzhou area were virus, mycoplasma and bacteria.The infection of RSV, bacteria, Candida albicans and mixed infection were much more common in children less than 3 years old.
