Detection and characterization of avian influenza H9N2 in a broiler farm in mauritania; 2024.
In October 2024, a broiler farm located south of Nouakchott, Mauritania, reported respiratory symptoms, diarrhoea, and 10% mortality within a flock of 4500 birds. Pooled organ samples (n = 6) were collected and screened by real-time RT-PCR for H5 and H9 subtype avian influenza viruses, Newcastle disease virus, infectious bronchitis virus, and infectious laryngotracheitis virus. Six samples were positive for H9. Full genome sequencing of a representative sample revealed that the viruses were H9N2 and belonged to lineage G5.5. Several molecular markers associated with adaptation to mammalian hosts were identified indicating the virus' potential to infect humans. Analysis of the eight segments showed that the virus was not a reassortant and that it was similar to H9N2 viruses identified in Senegal. This is the first report of H9N2 in Mauritania, and the data generated will be of interest to national and regional veterinary and public health authorities.
期刊介绍：
Veterinary Research Communications publishes fully refereed research articles and topical reviews on all aspects of the veterinary sciences. Interdisciplinary articles are particularly encouraged, as are well argued reviews, even if they are somewhat controversial.
The journal is an appropriate medium in which to publish new methods, newly described diseases and new pathological findings, as these are applied to animals. The material should be of international rather than local interest. As it deliberately seeks a wide coverage, Veterinary Research Communications provides its readers with a means of keeping abreast of current developments in the entire field of veterinary science.
