'In the particular instance what was involved was the role and importance of the host organism. Microbes altered their forms in response to environmental stress. Disease microbes responded in this way to unfavorable or hostile conditions in the host organism. Pleomorphism meant that the host was an active participant in infection and disease- in contrast to Koch and the monomorphists who held the microbe to be all-powerful, the host organism a passive victim. Pleomorphism meant downgrading the microbe, since the host, by resisting the latter’s onslaught, could alter its characteristics.'
