[Microarray-based transcriptome analyses in infectious diseases. A new diagnostic method].

The complex interaction between a pathogen and a host is the molecular basis of infectious diseases. Microarray technology is a powerful tool to investigate the crosstalk between pathogen and the host as it assesses whole genome expression profiles in response to disease. Deciphering the molecular details on both sides of the host-pathogen interaction will increase our understanding of the pathogenesis of infectious diseases and offer improvements in their diagnosis, treatment, prognosis, and prevention.
