Major mood events have give up land bridges during prehistory , along which animals and humans traveled to novel continents . A new study propose that major atmospheric condition event , like El Niño , open up “ body of water bridges ” that allow bacteria to do the same .
An outside squad of researcher has been working with the National Institute of Health ( INS ) in Peru , looking at the genetic account of pathogens that have bound up in Latin America over the preceding few decade . They found leftover correlations with pathogen that were already established in Asia .
This could be attributed to people or farm animal carry the pathogen making it across the ocean in boats . But based on the timing , the investigator consider it could be an unknown consequence of El Niño . Theirfindings are publishedin Nature Microbiology .
When expect at disease - cause agent , the researchers were specifically seem atvibrios — bacteria that float around in sea water . Not all of these bacteria are harmful , but about a dozen make serious illnesses , include cholera and the deep misery that ’s the result of eatingundercooked mollusk .
A horrible Asiatic cholera outbreak in 1990 killed 13,000 people in Peru . In 1997 and 2010 , there were two major outbreaks of Vibrio parahaemolyticus , the bacteria that contaminates shellfish . These outbreaks also correspond with major El Niño weather condition phenomenons .
The bacterium are n’t effective travelers on their own , but they do associateclosely with zooplankton . Zooplankton are adept drifter , particularly if something turn over them an chance to travel . The researchers conceive that major El Niño events give them just such an chance . While we ’re focused on the atmospheric condition , an unseeable bridge of water could be open up between continents , letting all kinds of microbic spirit traveling from one shore to the other .
This imply that El Niño is n’t just a time when coastal saving or disaster ministration servicing have to be on precaution — it ’s a time when interior health services ask to prepare for foreign pathogen to end up on local shoring .
