Immunosuppressive potential and pathogenicity of recent of isolate of infectious bursal disease virus in commercial broiler chickens
At 15 days of age and in the presence of measurable levels of maternal antibody against infectious bursal disease virus serotype I (1:170 virus-neutralization geometric mean titer), a recent isolate (U-28) and a prototype virulent isolate (Edgar) of the same virus caused subclinical infections in co...

| description | At 15 days of age and in the presence of measurable levels of maternal antibody against infectious bursal disease virus serotype I (1:170 virus-neutralization geometric mean titer), a recent isolate (U-28) and a prototype virulent isolate (Edgar) of the same virus caused subclinical infections in commercial broiler chickens. Isolate U-28 caused a significant reduction in the size of the bursa of Fabricius, whereas the Edgar isolate produced splenomegaly. Both isolates reduced the serological response to Newcastle disease virus. The experimental immunosuppressive potential and pathogenicity of isolate U-28 in broiler chickens confirms the role of this virus in recent infectious bursal disease outbreaks. /// Una cepa recientemente aislada del virus de la enfermedad infecciosa de la bolsa (Gumboro) designada como U-28 y una cepa virulenta prototipo del mismo virus conocida como cepa Edgar causaron infección subclínica en pollos de engorde infectados a los 15 días de edad. El promedio geométrico de los niveles de anticuerpos maternales contra Gumboro medidos en la prueba de virus neutralización era de 170. La cepa U-28 causó una reducción significante en el tamaño de la bolsa de Fabricio, mientras que la cepa Edgar causó esplecnomegalia. Ambas cepas redujeron la respuesta serológica contra el virus de la enfermedad de Newcastle. El potencial inmunosupresor y la patogenicidad de la cepa U-28 confirma el papel de este virus en los brotes recientes de la enfermedad infecciosa de la bolsa. |
