El comercio de vida silvestre es probablemente la fuente del SARS-CoV-2
1Department of Biological Sciences, Xi'an Jiaotong-Liverpool University (XJTLU), Suzhou, China.
Resumen
Es probable que la aparición del SARS-CoV-2 (Coronavirus del Síndrome Respiratorio Agudo Severo 2) haya sido causada por la transmisión múltiple de animales salvajes. Este evento zoonótico probablemente se originó en un mercado en Wuhan, China.
Área de la Ciencia:
- Aparición de enfermedades zoonóticas
- Epidemiología
- Virología
Sus antecedentes:
- La pandemia de COVID-19, causada por el SARS-CoV-2, ha tenido un profundo impacto global.
- Comprender los orígenes del SARS-CoV-2 es crucial para prevenir futuras pandemias.
Objetivo del estudio:
- Para investigar el probable origen de la aparición del SARS-CoV-2.
- Identificar las posibles vías de transmisión de la vida silvestre a los humanos.
Principales métodos:
- Análisis de los datos epidemiológicos.
- Revisión del comercio de vida silvestre en los mercados de Wuhan.
- Secuenciación genómica y análisis filogenético del SARS-CoV-2.
Principales resultados:
- La evidencia sugiere que se produjeron múltiples transmisiones zoonóticas independientes.
- El mercado mayorista de mariscos de Huanan en Wuhan se identifica como un posible epicentro.
- La presencia de SARS-CoV-2 en la vida silvestre vendida en el mercado apoya un origen zoonótico.
Conclusiones:
- Es probable que las múltiples transmisiones de la vida silvestre en un mercado de Wuhan hayan llevado a la aparición del SARS-CoV-2.
- Los hallazgos subrayan la importancia de controlar las interfaces entre la vida silvestre y el ser humano para detectar enfermedades infecciosas emergentes.

Viral Recombination
23.7K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Threats to Biodiversity
22.7K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Single Nucleotide Polymorphisms-SNPs
15.7K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Viral Mutations
32.8K
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...
