Technical Abstract: Five overlapping cosmid clones were constructed that contain the entire genome of a very virulent strain (Md5) of Marek's Disease Virus (MDV). Transfection of chicken or duck embryonic fibroblasts with the five cosmids resulted in the production of infectious MDV. Generation of recombinant MDV using cosmid DNAs will be useful for studying the function of viral genes in MDV replication and transformation. Furthermore, manipulation of the MDV genome might allow one to produce deletion mutant vaccines or a virus that encodes foreign antigens for use as a polyvalent live virus vaccine.
