Question and Answer

Does OE affect humans or pets?

Luckily, OE only affects a few butterfly species. It does not affect humans in any way and there is no chance that it could adapt to infect humans.  This pathogen is not closely related to any human pathogen and it has only been reported to infect insects.  The spores require a very precise pH shift to activate in larval guts, which our bodies fortunately do not have.  It is a very good question, though, as some insects vector medically important pathogens to humans.
