Gunshot or other trauma preventative antibiotics

[Fentonite]

You can get gram negative coverage by using a broader agent but in most cases it won't be necessary although it depends on whether you were infected from the object, from post contamination or from your own flora which was what I was covering for.

For most "civilian" wounds, I would agree with you. However, combat-related wounds have a higher incidence of soil and vegetation contaminants, and should be prophylaxed accordingly. Just my two cents.
