• To evaluate the relationship among immune status and increased morbidity and mortality, peripheral blood lymphocytes (CD3+, CD4+, CD8+ and CD21+ cells) from 32 healthy dogs over 8 years of age were analyzed. Twenty-five of the 32 dogs were followed-up for 3 years after the analysis; and 14 dogs were found to be diseased, and nine dogs died. There was no notable difference between the ages of the dogs that died compared with the ones that survived. The relative percentage of CD4+ and the CD4+:CD8+ ratio decreased notably in dogs falling ill compared with healthy dogs. The relative percentage of CD3+ lymphocytes showed a notable decrease in dogs that died within 3 years in comparison with dogs that survived. In a discriminant analysis of morbidity and mortality, most patients were correctly classified as diseased or not and surviving or dead, respectively. These results indicate that the immunophenotypes of peripheral blood lymphocytes in older dogs offer promise as parameters for evaluating mortality and morbidity.
