The fowl pox is a severe and common viral disease of the canary birds. In the following report both cutaneous and respiratory shapes from a Fife and Gloster canary breeding were observed. The disease was responsible of conjunctivitis, vesciculae and pustulae all around the eyes and the beak; after, a distribution of the lesions as scabs on the toes was registered too. The diagnosis was confirmed by viral isolation on CAM of chicken embryos; characteristic viral pox particles were identified from scabs with electron microscope. All the canary breeders (a total of 20 couples) were immunized using a commercial vaccine (Poulvac® canary pox FOI, Fort Dodge Animal Health). The first group of 10 couples was also treated with Isoprinosine, while the other 10 couples were used as control group. For each couple of both groups, the number of laid eggs, the number of fertilized eggs, the number of chicks born and the number of chicks weaned were evaluated during the first (December-January) and second (February-March) brood period. None of the canaries showed effects after vaccination and treatment with isoprinosine. The reproductive performances and particularly the number of weaned chicks, improved significantly during the second brood period in both groups; nevertheless the group treated with isoprinosine showed an higher number of weaned chicks.

Abstract
The fowl pox is a severe and common viral disease of the canary birds. In the following report both cutaneous and respiratory shapes from a Fife and Gloster canary breeding were observed. The disease was responsible of conjunctivitis, vesciculae and pustulae all around the eyes and the beak; after, a distribution of the lesions as scabs on the toes was registered too. The diagnosis was confirmed by viral isolation on CAM of chicken embryos; characteristic viral pox particles were identified from scabs with electron microscope. All the canary breeders (a total of 20 couples) were immunized using a commercial vaccine (Poulvac® canary pox FOI, Fort Dodge Animal Health). The first group of 10 couples was also treated with Isoprinosine, while the other 10 couples were used as control group. For each couple of both groups, the number of laid eggs, the number of fertilized eggs, the number of chicks born and the number of chicks weaned were evaluated during the first (December-January) and second (February-March) brood period. None of the canaries showed effects after vaccination and treatment with isoprinosine. The reproductive performances and particularly the number of weaned chicks, improved significantly during the second brood period in both groups; nevertheless the group treated with isoprinosine showed an higher number of weaned chicks.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
