The occurrence of decreased activity of the immune system was studied in a group of 66 dogs with various combinations of pyoderma and demodicosis. Our complex examination of the dogs included the following: leukocyte count, differential count, phagocytosis, blastogenic lymphocyte transformation and quantitation of total serum immunoglobulins, lysozyme and haemolytic complement. Immunosuppression was found in 19 (28.8%) cases. Immunosuppression was rare in dogs with demodicosis and did not appear without a concurrent pyoderma. An increase in the neutrophil counts and total serum immunoglobulin levels significant was found in dogs with demodicosis combined with pyoderma. On the contrary, marked immunosuppression was detected in dogs with deep pyoderma. A considerable immunosuppression was present in 7 of 10 German shepherds dog pyoderma (GSP). Significant depressions were found in phagocyte activity and lymphocyte activity. Immunosuppression was observed in 4 of 9 dogs in other breeds with uncomplicated deep pyoderma. All groups of dogs with pyoderma showed a significant increase in total serum immunoglobulins. Conclusion from these findings is that deep pyoderma more than Demodicosis was concerned with immunosuppression. German shepherds with deep pyoderma had more expressed immunosuppression than other breeds.
