Giardia muris
Affect mice; trophozoites on a wet mount; tx with metronidazole; not the same disease but practically speaking may as well be

Syphacia obvelata & Aspic spp (like mice)
Also Syphacia mura
Gerbils are listed as getting “pinworms” but no species given

secondary to penicillin, lincomycin, cephalosporins, bacitracin
dx via PCR to identify pathogenic strain
Clostridium piliforme diarrhea hamsters
Tyzzer’s disease
depressed, dehydrated, diarrhea, dull/dirty coat
opportunistic in stressed animals
Clostridium piliforme/bacillus piliforme gerbils
They get it a lot and also die from it a lot
