ABSTRACT
Avian influenza virus is a new recombinant virus , which can cause severe respiratory symptoms ,such as short course,acute disease,and a high mortality rate.The purpose of this paper was to summarize the current status of this virus in terms of its epidemiology ,genetic evolution and virulence .By introducing the advancement in the research of this subtype virus, we hope to provide data and evidence ,for effective surveillance and prevention of this virus .
ABSTRACT
Detection of pathogenic microorganisms has been a hot research field of microbiology.Conventional detection methods,such as isolation and culture, PCR technology, ELISA and genomic sequencing,are all time-consuming and com-plex.Because of the advantages of quick-testing, accuracy, safety and efficiency, spectroscopy has become a new non-inva-sive testing technology and has witnessed rapid development in pathogen detection and disease diagnosis.This article intro-duces three types of common spectroscopy technologies ( laser excitation fluorescence spectroscopy, infrared spectroscopy and Raman spectroscopy) , and also explains how they work in the detection of pathogenic microorganisms.
