呼吸道病毒感染可以导致大面积人群致病1],近些年,临床上由于不明原因导致的小儿下呼吸道感染病例屡见不鲜,对于该类患儿一般采取抗生素混合治疗的方法,但是治疗效果不佳.尽管过去几年开展的多项研究已经鉴定到了很多的病原体,如腺病毒,鼻病毒属病毒,冠状病毒属病毒,呼吸道合胞体病毒,流感病毒,副流感病毒等.

Identification of KI Polyomavirus in Children with Lower Respiratory Tract Infections from Zhejiang Region of China

KI polyomavirus,which was firstly discovered in 2007,is a new human polyomavirus belonging to Polyomaviridae and containing circular double-strand genomic DNA.This study was based on identification assay of KI polyomavirus reported.Total 2293 clinical sputum specimens from children under 3 years old were collected and screened from Wenzhou Medical College affiliated Wenling Hospital,Zhejiang Province.A KI polyomavirus was detected and identified,the positive rate was 0.04%.The sequences of PCR products was identical to that of the viral capsid protein(VP1) gene derived from KI polyomavirus.The results strongly suggested that the KI polyomavirus was found firstly in Chinese children with acute lower respiratory tract infections from Zhejiang region.This study provided new information for further investigation of etiopathogenisis and diagnosis in children with lower respiratory tract infections.
