El Niño will make the bacterial community migrate across the continent

During prehistoric times, major climatic events were accompanied by the formation of land bridges, helping plants, animals and humans move to continents. new.

A recent study suggests that current weather events like El Niño, will open such bridges, allowing bacteria to make a transcontinental "migration" . Through working with the National Institutes of Health (INS) in Peru, an international research group has looked at the genetic history of emerging pathogens in Latin America over the past few decades. As a result, they found a strange correlation between this pathogen, which has been formed in Asia before.

The cause for this phenomenon may come from humans or livestock, which inadvertently brought pathogens through the ocean by boat.

The cause for this phenomenon may come from humans or livestock, which inadvertently brought pathogens through the ocean by boat. But based on time, researchers believe that the problem may be an unknown consequence of the impact of El Niño. When looking at the pathogens, the researchers have seen vibrios - the floating bacteria present in seawater. Not all of these bacteria are harmful, but about a dozen of them cause serious illnesses, including cholera and acquired diseases when eating unprocessed seafood.

A cholera epidemic broke out in 1990 and killed 13,000 people in Peru. In 1997 and 2010, there were two outbreaks that originated from Vibrio parahaemolyticus (sea description) , bacteria that cause disease in seafood species such as shrimp, crabs, oysters, . Especially the flare. This explosion happened at the same time as the El Niño weather phenomenon. Bacteria in themselves are not able to move efficiently, however, they are always closely linked to zooplankton.

Zooplankton are known as champion "riders" , especially if something motivates them. Researchers believe that the El Niño event itself provides this zooplankton . While we are focusing on weather issues, invisible bridges in the country may have been opened between continents, allowing all living microorganisms to move to the shores. other.

This means that El Niño is not merely a factor worthy of attention by coastal disaster rescue or rescue services. The new discovery will prompt national health services to quickly cope with pathogens, when they launch "attacks" on new lands.
