Tomato juice can kill Salmonella Typhi and other bacteria that can harm people's digestive and urinary tract health, according to research published in Microbiology Spectrum, a journal of the American Society for Microbiology.
First, the researchers, in laboratory experiments, checked to see if tomato juice really does kill Salmonella Typhi. Once they ascertained it did, the team looked at the tomato's genome to find the antimicrobial peptides that were involved. Antimicrobial peptides are very small proteins that impair the bacterial membrane that keeps them as intact organisms. The researchers chose 4 possible antimicrobial peptides and tested how well they worked against Salmonella Typhi. This helped them find 2 antimicrobial peptides effective against Salmonella Typhi.
The research team conducted more tests on Salmonella Typhi variants that appear in places where the disease is common. They also did a computer study to learn more about how the antibacterial peptides kill Salmonella Typhi and other enteric pathogens. Lastly, they looked at how well tomato juice worked against other enteric pathogens that can hurt people's digestive and urinary tract health.
The most significant discovery is that tomato juice is effective in eliminating Salmonella Typhi, its hypervirulent variants, and other bacteria that can harm people's digestive and urinary tract health. In particular, 2 antimicrobial peptides can eliminate these pathogens by impairing the bacterial membrane, a protective layer that surrounds the pathogen.
