Therefore, the combination of these salivary biomarkers in a complete salivary panel, next to other salivary biomarkers such as ADA, S100A12 [17] or even the oxidative stress biomarkers [12,34], may enhance their diagnostic utility in practice to detect animals with gastric ulceration and even to distinguish between the clinical states of the EGUS. This evidence concerns the gene ADA and gastric ulcer.
