WebWhat is host specificity of a virus? Viruses are host-specific because they only can attach to and infect cells of certain organisms. Cells that a virus may use to replicate are called permissive. The virus attacks the host cell by first attaching to a specific receptor site on the membrane of the host cell. What is meant by narrow host range? Webprecipitation. The validation exercise successfully passed all criteria for specificity, linearity, accuracy, repeatability, intermediate precision, range and LOQ. Residual host-cell DNA is a process impurity in recombinant biotherapeutic products. Levels of host cell DNA needs to be monitored during process development and validation.

This explains why most pathogens are only capable of infecting a limited range of host organisms. Researchers can classify pathogenic organisms by the range of species and cell types that they exhibit host tropism for.
