Article Synopsis
- * Eleven strains were isolated from wild birds and domestic poultry, revealing two main genotypes (S and A) with distinct shedding patterns and pathogenic impacts on ducks.
- * Findings indicate ongoing interspecies transmission of H9N2 in Yunnan, emphasizing the need for further epidemiological research to understand its spread among bird populations.
Article Synopsis
- - Fowl adenoviruses (FAdVs) are found worldwide in poultry and are linked to various health issues, with a new strain identified in black-necked cranes, classified as serotype 4 (BNC2021).
- - The genomic analysis of BNC2021 revealed specific gene deletions and mutations associated with increased viral pathogenicity.
- - A study demonstrated that this strain can infect mallard ducks, causing hepatitis-hydropericardium syndrome and widespread viral replication in multiple organs, emphasizing the need for monitoring FAdVs in wild bird populations.
The seasonal migration of wild aquatic birds plays a critical role in the maintenance, transmission, and incursion of the avian influenza virus (AIV). AIV surveillance was performed during 2020-2021 in two national nature reserves with abundant wild bird resources in Yunnan, China. Four H5N8 AIVs isolates from the common crane were identified by next-generation sequencing.

In this study capillary zone electrophoresis (CZE) was used to analyze the poly(ethylene glycol)-modified bovine hemoglobin(PEG-bHb). The results show that CZE separated the subunit of bovine hemoglobin based on the number of PEG conjugating to the protein surface, which makes it possible to evaluate the degree of modification of hemoglobin subunit; meanwhile, it also reflected the stability of PEG attaching to hemoglobin after incubating with hydroxylamine, which makes it successful to detect the distribution of attachment site and evaluate the stability of PEG on the surface of hemoglobin. As a simple, fast and accurate method, CZE is suitable to monitor the production procedures and quality control of the final products of the PEG-bHb.
