Common worm provides insights into salmonella virulence
...indings could ultimately lead to improved drugs to prevent or treat Salmonella infections. The researchers found four genes related to the Salmonella's "molecular syringe" that are required for the bacteria to have maximum potency in infecting the worm, known as Caenorhabditis elegans.
