No, you are right and I did not intend to imply that wormers had any effect
on gut bacteria. I just relayed it as an analogous situation where
medication may make room for more problems even though it may solve some. I
was thinking more along the lines of using wormers causing the horses not to
develop their own arsenal of weapons to fight worms off themselves. Or
side effects from basically overdosing wormers. Things like that.

Agreed.
