[Gumboro's disease continues to claim attention: a case report].
An outbreak of Gumboro disease occurred at the end of 1988 on a broiler farm having four houses and birds of two different age groups. The infection 'lingered' in the subsequent flocks, a striking feature consisting in the fact that the pattern of disease was identical in almost every case. Symptoms of Gumboro disease were not observed in the compartment housing the oldest broilers. The birds in this house continued to show low titres at the close of the fattening period. Gumboro disease was observed on the 19th and 20th days of life or on the 29th-33rd days of life in the other houses. Mortality was highest in the latter case. The final conclusion is that the difference in age between the houses probably makes the high pressure of infection possible. Consistent vaccination reduced the problem of Gumboro disease on the farm.
