Prevalence of Dog Erythrocyte Antigen 1 in 7,414 Dogs in Italy

الملخص EN

The study aim was to establish the prevalence of DEA 1, the most immunogenic and clinically important blood group in canine blood transfusion, in 7,414 dogs from Italy.

The potential sensitization risk following a first transfusion and the acute reaction risk following a second transfusion given without a cross-matching and blood typing test were also calculated.

Dogs tested were purebred (4,798) and mongrel (2,616); 38.8% were DEA 1 negative and 61.2% were DEA 1 positive.

High prevalence for DEA 1 positive blood type was found in Ariegeois and English Setter, whereas German Shepherd and Boxer had higher DEA 1 negative blood type.

Breeds with blood type never reported before included French Brittany Spaniel and Pug showing a high prevalence of DEA 1 positive type, while French Bulldog and West Highland White Terrier were more often DEA 1 negative.

Just 48.8% of purebred and 13.9% of mongrel dogs were considered as prospective blood donors based upon their blood type.

Most of the breeds had a sensitization risk of 20.0–25.0%.

Rottweiler and Ariegeois had less risk of sensitization (9.4 and 4.2%) and the minor risk of an acute transfusional reaction (0.9–0.2%).

The prevalence of DEA 1 positive and negative dogs in Italy agrees with most of the data already reported in the literature.
