Scientists in Britain have utilized CRISPR-Cas9 <\/a>to curb the multiplication of avian flu virus in poultry. This is even as bird flu, traditionally associated with Asia, continues to spread to Europe, Africa and North America.<\/p>\n\n\n\n

News of the breakthrough were published on the journal Nature Communications on October 10, 2023. Researchers announced that 9 out of 10 edited-gene chickens successfully fought infection from the Influenza A virus (IAV)<\/a>.<\/p>\n\n\n\n

The gene editing technique in the case study used amino acid blocks to rebuild DNA.<\/p>\n\n\n\n

There were tests, however, that showed that the virus could mutate and resist gene-edited DNA. Experimentation with overdose of gene substitutions in form of ANP32A amino acid<\/a> led to immediate infection.<\/p>\n\n\n\n

Possible mutations are worrying, considering the widespread reach of the highly infectious strain of IAV, whose first identification was in 2022<\/a>. Consequently, millions of poultry have undergone culling globally, including in the U.S., the UK, the Gambia and South Africa.<\/a><\/p>\n\n\n\n

Gene-Editing Program<\/h3>\n\n\n\n

Since 2005, scientists in Hong Kong and Europe have collected 10,000 DNA sets<\/a> of the virus. Study on these sets and DNA alteration via gene-editing are helping to get closer to medical breakthroughs.<\/p>\n\n\n\n

CRISPR-Cas9 is a gene-editing program that can grow genetically modified fowls that are resistant to avian flu to a degree.<\/p>\n\n\n\n

With gene-editing, scientists can edit <\/a>or adjust particular parts of a genome, which is the entire information path of the DNA. This makes it possible to remove or augment DNA locations that promote disease.<\/p>\n\n\n\n

Analysts in the UK say that such a move would save the British poultry sector 100 million Sterling Pounds.<\/p>\n\n\n\n

The technique could also prevent that rare scenario where avian influenza jumps to humans and causes a pandemic.<\/p>\n\n\n\n

Gene editing may not only offer long-lasting resilience to poultry but is the way to \u201creducing the risks to human<\/a>s.\u201d This is according to Professor Mike McGrew, a researcher with the Roslin Institute of University of Edinburgh.<\/p>\n\n\n\n

China was the first to report a case of avian flu in 1996 in a goose. The first human infection took place in 1997 in Hong Kong.<\/p>\n\n\n\n

The initial human infection case of the H10N3 avian flu strain<\/a> also occurred in China in 2021. This was 5 years after the deadly H7N9 which killed 616 people between 2013 and 2017.<\/p>\n","protected":false},"excerpt":{"rendered":"
