Haemagglutination inhibition antibody responses of pullet and broiler chickens (<i>Gallus gallus domesticus</i>) to Newcastle disease virus LaSota vaccination

Abstract: Newcastle disease outbreaks still occur sporadically in commercial vaccinated flocks and remains a constant threat to poultry producers despite advances in vaccination against the disease. Another aspect that can be a complementary control strategies or that is well recognized but is often neglected is the differences in immune response due to genetic or breed/type variation. This study investigated the immune responses to LaSota vaccination in light weight type or breeds of chickens (pullets) and heavy weight… Show more

“…Newcastle Disease (ND) continues to negatively impact poultry farmers and poultry-producing nations by infecting birds worldwide, despite the advances made in diagnosis and vaccination since it was rst discovered in 1926 (Mahamud et al, 2022;Moustapha et al, 2023). An aspect that can be part of complementary control strategies but is often neglected is the differences in immune response due to genetic variation (Igwe et al, 2018). In Zimbabwe, vaccination against Newcastle Disease is one of the main control measures of Newcastle Disease Virus (NDV) with its endemic occurrence in poultry farms.…”

“…For this purpose, live vaccines containing apatogenic, lentogenic, or asymptomatic intestinal NDV strains, or inactivated vaccines are used [3][4][5]. Although currently available commercial vaccines prevent the morbidity and mortality of ND, they are unable to prevent infection with, replication, and shedding of virulent NDV strains [6][7][8]. Furthermore, Life 2022, 12, 72 2 of 12 prevalent contemporary circulating velogenic NDV strains are viscerotropic in nature, which makes widely used commercial vaccines based on pneumotropic strains inadequate to protect animals.…”
