Cryptosporidiosis in Ball Pythons

Reptile · Python regius · typical adult weight 1.00–2.00 kg

3 cited drugs treat Cryptosporidiosis in ball pythons: Azithromycin, Paromomycin, Ponazuril.

Protozoal enteric infection caused by Cryptosporidium spp. — significant in calves, lambs, foals, reptiles (notably leopard geckos via C. saurophilum), and as a zoonotic concern. No reliably effective antiprotozoal in many species; supportive care remains the mainstay.

The overview above describes Cryptosporidiosis across species; the citations below are the ExoticRx dose rules scoped to ball pythons — a reference list, not new species-specific clinical guidance.
