IOWA CITY —
One final note — while we often consider humans the victims of such pandemic events, that's not always the case. Zoonoses are a two-way street, and humans can also spread our own native microbes to other species. Recent studies have shown that humans have spread antibiotic-resistant strains of Staphylococcus aureus to many different species, including domestic chickens, pigs and even chimpanzees and dolphins. We, too, are a walking biohazard.
