New Design May Produce Heartier, More Effective Salmonella-Based Vaccines

 

August 6, 2013 -- The bacterial pathogen Salmonella has a notorious capacity for infection. Last year alone, according to the Center for Disease Control, various species of Salmonella caused multistate disease outbreaks linked with contaminated peanut butter, mangoes, ground beef, cantaloupe, poultry, tuna fish, small turtles and dry dog food.

The troublesome invader, however, can be turned to human advantage. Through genetic manipulation, the species S. Typhi can be rendered harmless and used in vaccines in order to prevent, rather than cause illness.

In new research, reported in the Journal of Bacteriology, lead author Katie Brenneman and her colleagues describe efforts to improve the effectiveness of a Recombinant Attenuated Salmonella Vaccine (RASV) by modifying its ability to survive the hostile environment of the stomach.
