Table 1 Modified scoring system for H. pylori density.
Density of H. pylori | Histological features |
|---|---|
0 | No Bacteria |
1 | Few bacteria (5 to 10) observed only under ×40 magnification |
2 | Patchy distribution (<50 of total surface crypts) with lower density (NCB<10) |
3 | Patchy distribution (<50 of total surface crypts) with higher-density (NCB>10) Or diffuse distribution (>50 of total surface crypts) with mixture of low-density (NCB<10) |
4 | Diffuse distribution (>20 of total surface crypts) with mixture of high (NCB>10) and low-density (NCB<10) |
5 | Diffuse distribution (>50 of total surface crypts) all with high density (NCB>10) |
