Researchers Discover Particularly Dangerous Salmonella

UC Santa Barbara researchers have discovered Salmonella bacteria that are up to 100 times more capable of causing disease. Their findings may help prevent food poisoning outbreaks that continue to plague public health and the food industry.

These “hypervirulent” bugs can override vaccines and pose a risk to food safety –– and mitigation efforts are currently under way.

Previous strategies to find the more dangerous bugs were unsuccessful since they behave like a “Trojan Horse”— exposing their weapons only when causing disease — but looking much like their less-virulent cousins in the environment.

Now that scientists know what to look for, they are developing methods to discriminate them from their less-virulent cousins. The researchers have been successful in forcing the bacteria to reveal their weapons in the laboratory –– the first step in combating them
