H7N6 highly pathogenic avian influenza in Mozambique, 2023.
On 13 October 2023, the National Directorate for Livestock Development in Mozambique was notified of a suspected outbreak of avian influenza in commercial layers. Samples were screened by real-time and conventional RT-PCR and were positive for both H7 and N6. Full genome sequences were obtained for three representative samples. Sequence analysis of the H7 cleavage site confirmed that the viruses were highly pathogenic (i.e. 333- PEPPKGPRFRR/GLF-346). In addition, the H7 and N6 sequences were highly similar (from 99.4-99.5% and 99.6-99.7% for the HA gene and the NA gene, respectively) to the sequences of a H7N6 virus identified in the Republic of South Africa in May 2023 indicating a similar origin of the viruses. The identification of H7N6 HPAIV in Mozambique has important implications for disease management and food security in the region.
期刊介绍：
Emerging Microbes & Infections is a peer-reviewed, open-access journal dedicated to publishing research at the intersection of emerging immunology and microbiology viruses.
The journal's mission is to share information on microbes and infections, particularly those gaining significance in both biological and clinical realms due to increased pathogenic frequency. Emerging Microbes & Infections is committed to bridging the scientific gap between developed and developing countries.
This journal addresses topics of critical biological and clinical importance, including but not limited to:
- Epidemic surveillance
- Clinical manifestations
- Diagnosis and management
- Cellular and molecular pathogenesis
- Innate and acquired immune responses between emerging microbes and their hosts
- Drug discovery
- Vaccine development research
Emerging Microbes & Infections invites submissions of original research articles, review articles, letters, and commentaries, fostering a platform for the dissemination of impactful research in the field.
