- Rodent (NSAID enteropathy)
- Reproducible barrier damage, short study duration
- Rodent microbiome differs significantly from human. No Bacteroides, higher Lactobacillus baseline
- 10–50 µg/kg IP or oral
- Plasma LPS, zonulin, lactulose/mannitol ratio
- Best for mechanistic studies. NOT for human microbiome translation
- Porcine (ischemia-reperfusion)
- GI anatomy closer to human, similar SCFA metabolism
- Expensive, requires surgical facilities, limited microbiome sequencing databases
- 50–200 µg/kg IV
- Histological tight junction staining, FITC-dextran flux
- Ideal for barrier function. Microbiome data interpretation still developing
- Human organoid (ex vivo)
- Uses human tissue, allows mechanistic control
- No live microbiome, can't assess systemic effects, expensive
- 1–10 µM in culture medium
- Transepithelial electrical resistance (TEER), permeability assays
- Perfect for tight junction mechanism. Zero microbiome relevance
- Germ-free rodent (colonised)
- Complete microbiome control, defined bacterial introduction
- Requires specialised facilities, expensive, microbiome development differs from conventional animals
- 10–30 µg/kg IP
- 16S sequencing, SCFA quantification, barrier histology
- Gold standard for causality. Proves microbiome changes are direct, not secondary
