Genomic and transcriptomic studies in Mycobacterium avium subspecies paratuberculosis.
Microarray technology is an important tool in functional genomic research. It has enabled a deeper analysis of genomic diversity among bacteria belonging to the Mycobacterium avium complex (MAC). In addition, the expression of thousands of genes can be studied simultaneously in a single experiment. With the complete genome sequence of a bovine isolate of M. avium subspecies paratuberculosis, and the independent construction of DNA microarrays in our laboratories, transcriptomic studies for this veterinary pathogen are now possible. Furthermore, the bovine genome sequence project is completed and bovine arrays have been developed to examine host responses to infection with M. avium subsp. paratuberculosis. Collectively, genomic and transcriptomic data has yielded novel insights surrounding the genetic regulation and biology of Johne's disease.
