Newcastle disease virus genotype VII.1.1 identified from backyard chickens with low antibody titer: Jimma Zone, Southwest Ethiopia.
BMC Vet Res
January 2025
College of Agricultural and Veterinary Medicine, Jimma University, Jimma, Ethiopia.
Background: Newcastle disease significantly impacts the global poultry industry and is prevalent in many African countries, including Ethiopia. The objective of this research is to determine the humoral immune response to Newcastle Disease Virus (NDV), identify the circulating NDV genotype, and evaluate the correlation between the diagnostic tests used in backyard chickens in the Jimma Zone, southwest Ethiopia.
Methods: A total of 90 swab and blood samples were purposively collected from symptomatic backyard chicken in the period between February and April 2022.

Following two human infections with the H10N3 avian influenza virus (AIV) in 2021 and 2022, a third case was discovered in Yunnan, China, in 2024, raising concerns about the potential for future pandemics. Recent studies have indicated that novel H10N3 viruses are highly pathogenic in mice and can be transmitted between guinea pigs via respiratory droplets without prior adaptation. However, the biological characteristics of novel H10N3 in poultry have not been fully elucidated.

Article Synopsis
- The transition of the highly pathogenic H5 avian influenza virus in Northern Europe led to significant deaths among wild birds and affected raptors that hunt or scavenge infected birds.
- Surveillance indicated that avian raptors not only carry the virus but also suffer from it, exemplified by the recorded deaths of white-tailed sea eagles in Germany.
- Despite initial concerns about the virus's impact on bird of prey reproduction, the stable breeding success of WTSEs in 2022 suggests potential resilience or evolving immunity may mitigate long-term effects.
