The discovery of the protein, dubbed STM3117, allowed the researchers to subsequently crippled the microbe’s ability to multiply inside macrophages. Drug and vaccine designers armed with this mouse-model information can target chemicals or immune responses that disrupt peptidoglycan synthesis and other processes linked to Salmonella’s colonization of macrophages in humans. A quick identification of these proteins could also help physicians assess the virulence of a given strain. The work was funded by PNNL and the National Institutes of Health’s National Institute of Allergy and Infectious Diseases, and much of the work was performed at the PNNL-based W.R. Wiley Environmental Molecular Sciences Laboratory. ### Other Salmonella Lawsuits [Ramona Family Naturals Market and Happy Hens Salmonella Outbreak Lawsuits](https://marlerclark.com/ramona-family-naturals-market-and-happy-hens-salmonella-outbreak-lawsuits) [Jalapeño Salmonella Outbreak Lawsuits: Chipotle, QDOBA and Coast Citrus Distributors — 431 Sick in 32 States](https://marlerclark.com/chipotle-linked-to-salmonella-outbreak-tied-to-peppers) [Egg Salmonella Outbreak Sickens 134 in 18 States](https://marlerclark.com/egg-salmonella-outbreak-sickens-98-in-17-states) [18 Sick with Salmonella from Moringa Capsules](https://marlerclark.com/18-sick-with-salmonella-from-moringa-capsules) [64 with Salmonella tied to Oysters](https://marlerclark.com/64-with-salmonella-tied-to-oysters) [Vega Farms Salmonella Outbreak Sickens 63](https://marlerclark.com/vega-farms-salmonella-outbreak-sickens-63) [Green Supplement causes Salmonella Outbreak](https://marlerclark.com/green-supplement-causes-salmonella-outbreak) [Salmonella Outbreak tied to Metabolic Meals](https://marlerclark.com/salmonella-outbreak-tied-to-metabolic-meals) [Kentucky Salmonella outbreak linked to Ramsey’s Diners and Missy’s Pies](https://marlerclark.com/kentucky-salmonella-outbreak-linked-to-ramseys-diners-and-missys-pies) [Salmonella Egg Outbreak sickens 63 in California](https://marlerclark.com/salmonella-egg-outbreak-sickens-63-in-california) [Cucumbers with Salmonella -
