البرتغالية. Este trabalho descreve un surto de Doença Infecciosa Bursal (DIB) ocorrendo em frangos de corte oriundos de reprodutoras imunizadas, alojadas em quatro granjas vizinhas e vacinadas ou nio vacinadas com vírus da DIB. Mortalidade elevada, mau desempenho e ocorrência de infecções múltiplas foram os principais achados de campo. A DIB foi reproduzida experimentalmente em galinhas SPF e comerciais através de inoculaçBo do homogenato de Bursa de Fabricius. Anticorpos contra vírus da DIB e partículas virais (33 a 38 nm) foram detectadas nas aves experimentalmenteinoculadas.
