due to virulence plasmid loss during subculturing
Because in culture outside of the host organism microbe or virus are not subject to immune response pressure, so their own genes that are responsible for virulence become not necessary and can be lost due to lack of selective pressure. Also, composition of the culture media can be such, that some important genes that are needed to pathogen's survival in its normal host stop being necessary. The whole thing is a lot like an atrophy of muscles when they are not used.
