Host cell science meaning
WebHost tropism. Host tropism is the infection specificity of certain pathogens to particular hosts and host tissues. 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.
