Table 2 Histopathological classification of bacterial translocation through the intestinal wall

From: Influence of two different levels of intra-abdominal hypertension on bacterial translocation in a porcine model

Bowel wall translocation score Histopathological appearance (bacterial count in 10 HPF)
Grade 0 No bacteria detectable (neither in mucosa nor in submucosa)
Grade 1 Few bacteria in the mucosa (up to five findings in 10 HPF)
Grade 2 Many bacteria in the mucosa (more than five findings in 10 HPF)
Grade 3 Bacteria in mucosa as well as in submucosa
