A few-polyhedra mutant and wild-type nucleopolyhedrovirus remain as a stable polymorphism during serial coinfection in Trichoplusia ni

Research reveals that a genomic parasite in artificial nucleopolyhedrovirus cell cultures is maintained through cell propagation in insects. Results show that a few-polyhedra mutant of nucleopolyhedroviruses is able to persisit in equilibrium with the wild-type strain during serial rounds of infection.
