Ode to Edith

Small viruses, we could not see And so relied on CPE To find them as they multiplied And thus they were identified. But Edith, who pursued the tracks Of polio, and saw its plaques Could tell them from Coxsackie B By Clinical Virology Which sorted out Pandora's Box From paraflu to chickenpox. Now, in this golden age of plastic Progress since has been fantastic Probes and RIA and kits Are quite enough to give one fits But only labs of dullest drones Now lack fluorescent monoclones! But lest we think that we're now wiser-Edith's better than ELISA*! (To find out what a virus is I'll pick our Edith over *Liz).
