Researchers have discovered more than 20 new viruses in bats in China. Meanwhile, which arouses concerns about the possibility that these diseases are transmitted to livestock or even human beings.
The study was conducted by researchers from the Provincial Provincial Laboratory of Control. Therefore, Prevention of Zoonotic Diseases in the province of Yunnan, China, at the Yunnan Institute for the prevention and control of endemic diseases. In addition, The study results were published in the journal Plos Pathogens on June 24 and were covered by the American magazine Newsweek.
Using genetic sequencing, researchers have identified 22 viruses in kidney tissues of 142 bats collected in the province of Yunnan between 2017 and 2021. Similarly, Among them, two are genetically similar to Hendra and Nipah Henipavirus concern goes after discovery new viruses. The analysis has also revealed other types of bacteria and a hitherto unknown parasite of scientists.
According to the team, the bats were found prowling near the orchards adjacent to the inhabited rural villages. This study. and more precisely the discovery of two viruses Hanipa hitherto unknown, now called Hénipa virus from Yunnan 1 and 2 bat, represents the first complete genome of this type of virus discovered in Chinese bats.
In addition to the discovery of viruses. the team also pointed out the presence of a unicellular parasite hitherto unknown, called Klossiella yunnanensis, as well as two very virulent bacterial species, including Flavobacterium yunnanensis, described for the first time.
Researchers have warned that urine could be a transmission route for Hénipa viruses. increasing the risk of fruit contamination by bats, which are then consumed by humans or animals, thus opening the way to an epidemic.
Professor Vinod Balasubramaniam. concern goes after discovery new a molecular virologist at Monash University in Australia, said: “These viruses are very worrying because they were mainly found in the kidneys of bats, an organ linked to urine production, which raises concerns about potential humans through contaminated fruits or water. »»
Hénipa viruses have been responsible for epidemics with high mortality rates in the past. Recently discovered Yunnan bat viruses share between 52 % and 57 % of their genetic equipment with these dangerous viruses.
While previous virological studies on bats have focused on faeces samples. this study focused on internal organs, and in particular kidneys, due to their role in the transmission of diseases. The results suggest that a wider range of microbial threats may exist in these sub-studied tissues. potentially increasing the risk of zoonotic transmission.
Viruses transmitted by bats have been involved in several major epidemics of zoonotic diseases. notably Ebola, Marburg, SRAS, the Middle East concern goes after discovery new respiratory syndrome (MERS) and COVID-19. These pathogens can be transmitted to humans directly. through intermediate hosts, often by the consumption of contaminated food or water.
