What animal has the most powerful digestive enzymes? - Quora Given the lack of data on pathogens infecting lions in the greatest percentage of lion populations, the consequences of infection upon the host species, the alterations to transmission and virulence of these diseases through combination of the viruses and their subtypes in a single host or how these combined pathogens respond to stochastic disease outbreaks, it should be considered that using any extant wild populations as a source for reintroduction programs should involve extreme caution.
