"While current ILTV live-attenuated vaccines are effective, some of the viruses used to make them can regain virulence--causing chickens to become chronically ill," says Yu.
Now, in a recent study, Yu used reverse genetics technology, which allowed him to generate new vaccines by inserting a gene from the ILTV virus into the NDV LaSota strain.
All vaccinated birds were protected against both ILTV and NDV, showing few or no clinical signs and no decrease in body-weight gain.
Adicionalmente la codificacion y la sintesis de glicoproteinas homologas como gB, gC, gH, gJ, gN, gM, gD, gE, gI, gG, gK y gL ocurren en la region especifica [U.sub.S] de genes conservados del ILTV (81).
Estos preparados son altamente eficaces pero poco seguros, debido al potencial de latencia del ILTV, por lo que se han asociado con una serie de efectos adversos, como es la diseminacion de cepas vacunales a galpones no vacunados (virulencia residual).
