For those who claim to subscribe to the intelligent (sic) design notion, parasitism is always embarrassing and not something they will normally bring themselves to discuss.
Take the battles medical science is having with the zika virus, the ebola virus, the malaria parasites, antibiotic resistent in pathogens, etc., for instance. If we assume for a moment that resistance to the various treatments is by design, not evolution, then one has to conclude that the designer is on the side of the parasites and is actively trying to out-manoeuvre medical science's efforts.
This study serves as a proof of principle that amoebae can support prolonged survival of Y. pestis in the environment.
Now we have the example of one of the most devastating disease organisms ever to hit mankind - the Black Death-causing Yersinia pestis - has been 'designed' to take refuge in the common amoeba which is abundant in soil and so provides a ready safe haven for Y. pestis to hide in.Viveka Vadyvaloo, PhD, Co-author
