A newly identified coronavirus in Brazilian bats shows approximately 72% genetic similarity to the Mers virus. Researchers are uncertain about its infectivity in humans and plan further studies in Hong Kong labs. The findings emphasize the role of bats in emerging viruses and the need for ongoing surveillance to address public health risks.
A recently discovered coronavirus in bats in Brazil shares genetic similarities to the Mers virus, although its potential risks to humans remain unclear. This novel virus was identified through collaborative research between experts from São Paulo, Ceará, and Hong Kong University (HKU). The genetic sequence of this new coronavirus exhibits approximately 72% similarity to the genome of Mers-CoV, with the spike protein showing a similar percentage in its structure, crucial for attaching to host cells.
The Mers virus was first detected in Saudi Arabia in 2012, resulting in over 850 fatalities across multiple countries. Researchers are keen to verify if the Brazilian virus poses a threat to humans, with preliminary findings indicating possible interaction between this virus’s spike protein and the receptor used by Mers-CoV. High-biosecurity laboratories in Hong Kong are expected to conduct further experiments to assess the potential risks associated with this newly found virus.
Recent studies, detailed in the Journal of Medical Virology (JMV), involved screening 423 swabs from 16 bat species. The research revealed seven different coronaviruses in samples collected from bats in Fortaleza, demonstrating similarities to strains associated with Mers found in humans and camels. Evidence of genetic recombination among these viruses has been noted, further emphasizing the genetic diversity present in bat coronaviruses.
The findings highlight the crucial role of bats as reservoirs for emerging viruses, underscoring the need for continuous epidemiological surveillance. Researchers advocate for systematic vigilance of bat populations to mitigate public health risks associated with coronaviruses. They stress the importance of collaborative efforts across various sectors to enhance surveillance mechanisms and share data effectively to prevent future epidemics and pandemics.
In summary, the discovery of a new bat coronavirus in Brazil that resembles the Mers virus raises concerns over its potential risks to humans, which remain unverified. Continued research and surveillance, especially in high-security settings, are essential for understanding and managing this emerging threat. The findings reiterate the vital role that bats play in the transmission of coronaviruses and the necessity for integrated monitoring systems to safeguard public health.
