The authors describe the course of an acute disease in a goose flock, affecting two age groups. The stocks were 2 and 3 weeks old geese, and five days after the appearance of the first clinical symptoms 99% of the animals died. The epidemiological investigation revealed inappropriate vaccination of the parent stock so the young geese were unprotected against exposure to the parvovirus, the causative agent of Derzsy's disease. This case draws attention to the importance of the proper vaccination programs in goose flocks and to the mass economical loss due to the failure of protection against the viral agent, which could have been avoided by following the rules of animal health.
