New research by a team from London’s Kingston University has shown how the food poisoning bacteria Campylobacter can multiply and spread inside micro-organisms called amoebae- which could lead to a better understanding of how bacteria survive and help efforts to prevent the spread of infection.
Researchers from London’s Kingston University have shown how a leading cause of bacterial food poisoning can multiply and spread – by using another organism’s cells as a Trojan horse.
Campylobacter jejuni is one of the most common causes of gastroenteritis in the United States and Europe, often infecting humans through raw or undercooked poultry. The new study revealed how the bacteria can infiltrate micro-organisms called amoebae, multiplying within their cells while protected inside its host from harsh environmental conditions.
As well as leading to a better understanding of how bacteria survive, the research could help efforts to prevent the spread of infection, according to lead author and PhD student Ana Vieira.
“Establishing that Campylobacter can multiply inside its amoebic hosts is important, as they often exist in the same environments – such as in drinking water for chickens on poultry farms – which could increase the risk of infection,” she said. “The amoeba may act as a protective host against some disinfection procedures, so the findings could be used to explore new ways of helping prevent the bacteria’s spread by breaking the chain of infection.”
