Replication deficient viruses have been used widely for replacing, repairing, and deleting target genes. These recombinant viruses are tested on research animals or patients in clinical trials. Although viral vectors distribute in the body, they are also disseminated into the environment through secretion and excretion processes. By studying the extent of shedding, a proper risk assessment can be performed and appropriate biocontainment can be achieved. Adenoviral and lentiviral vectors were produced from commercially available kits. The transgene present in both vector systems was the lacZ reporter gene encoding for β-galactosidase. Primers and probes were designed for the encapsidation region of …
