本文研究目的是:试图通过对婴幼儿支气管肺炎的咽试子病毒分离、鉴定和血清学诊断,初步了解该病的病毒病因,特别是合胞病毒的分布情况以及新分离合胞病毒株在多种细胞培养基上产生的细胞病理形态改变的特性。一、病毒分离:从221份患儿咽试子标本中分离到合胞病毒29株,阳性率占13.1％。腺病毒42株,占19.0％。单纯疱疹病毒8株,占3.6％,未能定型的血球吸附病毒2株,占0.9％。 The purpose of this study is to try to understand the etiology, especially the distribution of syncytial virus, and the new isolated syncytial virus in nasopharyngeal bronchopneumonia by the isolation, identification and serological diagnosis of pharyngitis virus Characteristics of cell pathological morphological changes produced on seed cells. First, virus isolation: From 221 children with pharyngeal specimens isolated from syncytial virus 29 strains, the positive rate accounted for 13.1%. 42 strains of adenovirus, accounting for 19.0%. Herpes simplex virus 8, accounting for 3.6%, failed to stereotypes 2 hemoglobin virus, accounting for 0.9%.
