Pathogen identification plays a key role in the diagnosis, treatment and control of infections. Sequence-based techniques for identifying pathogens have appeared rapidly following the large-scale availability of genome nucleotide sequences. A DNA microarray is one such technique with multiplex properties in that they have the capability to screen all the known pathogens and also yet to be identified pathogens. The DNA microarray uses oligonucleotide probes, which are unique to a pathogen with respect to all other pathogens and nonpathogen genomes. Considering the importance of this technique, this article reviews microarray chips used for diagnosis of the viral pathogens and evaluates their performance and future prospects.
