“…In our study, calving signi cantly increased ADA1 isoenzyme in both serum and saliva. An increase of ADA in serum after calving had been previously described [4], and therefore ADA has been proposed to be a marker of a proin ammatory status of the animal due to calving [45]. To the authors' knowledge, this is the rst report in which salivary ADA has also been reported to increase after calving in cows, being this change of higher magnitude of that reported in serum.…”

Background: Measurement of adenosine deaminase (ADA) can provide information about cell-mediated immunity. This report’s objetive was to study the enzymatic activity of total ADA (tADA) and its isoenzymes ADA1 and ADA2 in canine, equine, porcine, and bovine serum and saliva and their changes in different inflammatory situations in each species. Besides, an automated method for ADA2 measurement was developed and validated.Results: tADA was present in serum and saliva of healthy animals of the four species. Erythro-9-(2-hydroxy-3-nonyl) adenine (EHNA) concentration of 0.47mM was needed for ADA1 inhibition in canine and porcine samples (serum and saliva) and bovine saliva, whereas for equine saliva 0.94mM was needed. ADA2 activity was not detected in bovine serum and was very low or absent in equine serum and bovine saliva. An automated procedure to measure ADA2 consisting of adding EHNA to a commercial reagent for tADA measurement provided repetitive (coefficients of variation <8.8% in serum and <10% in saliva) and accurate (linearity under dilution approaches gave R 2 >0.90) results, being equivalent to a manual incubation of the sample with EHNA at a similar concentration. Salivary tADA, as well as ADA1 and ADA2, were higher in dogs with leishmaniosis, horses with acute abdominal disease and pigs with lameness than in healthy animals. ADA showed significant correlation with serum ferritin in dogs ( r = 0.602, P <0.01; r = 0.555, P <0.05; and r = 0.632, P <0.01; respectively for tADA, ADA1 and ADA2) and serum C-reactive protein in pigs ( r = 0.700, P <0.01, for both tADA and ADA1; r = 0.770, P <0.001, for ADA2), whereas salivary ADA2 significantly correlated with serum amyloid A in the horse ( r = 0.649, P <0.01). In the cow, salivary tADA and ADA1 significantly increased after calving, correlatingd with total white blood cell count ( r = 0.487, P <0.05, both).Conclusions: ADA activity, as well as its isoenzymes, can be measured in serum and saliva of different animal species. The salivary levels of these analytes could potentially be inflammatory biomarkers in these species.

An automated procedure to measure ADA2 consisting of adding EHNA to a commercial reagent for tADA measurement provided repetitive (coefficients of variation < 8.8% in serum and < 10% in saliva) and accurate (linearity of serial sample dilutions with R2 > 0.90) results, being equivalent to a manual incubation of the sample with EHNA at a similar concentration. Salivary tADA, as well as ADA1 and ADA2, were higher in dogs with leishmaniosis, horses with acute abdominal disease and pigs with lameness than in healthy animals. tADA and isoenzymes in saliva showed a positive significant correlation with serum ferritin in dogs (r = 0.602, P < 0.01; r = 0.555, P < 0.05; and r = 0.632, P < 0.01; respectively for tADA, ADA1 and ADA2) and serum C-reactive protein in pigs (r = 0.700, P < 0.01, for both tADA and ADA1; r = 0.770, P < 0.001, for ADA2), whereas salivary ADA2 significantly correlated with serum amyloid A in horses (r = 0.649, P < 0.01). In cows, salivary tADA and ADA1 significantly increased after calving, correlating with total white blood cell count (r = 0.487, P < 0.05, for both tADA and ADA1). Conclusions The activity of total ADA and its different isoenzymes, can be measured in serum and saliva of dogs, horses, pigs and cows by a simple and fast procedure described in this report. When measured in saliva, these analytes correlated with other biomarkers of inflammation and it could potentially be used as a biomarkers of inflammation and immune activation in the species of this study.

The isoenzyme ADA1 is mainly present in lymphoid
