San Francisco: Before you eliminate meat from the diet, you should know that plant-based foods can also deliver antibiotic-resistant bacteria to your gut microbiota, researchers warn.

The US Centers for Disease Control and Prevention estimates estimate that 20 percent of the two million antibiotic-resistant infections per year are agricultural-related.

This estimate is based on patients who directly purchase antibiotic-resistant superbugs from the consumption of meat.

"Our findings underscore the importance of combating antimicrobial resistance through food from the perspective of the whole food chain, which includes meat as well as plant-based foods," said Marlene Maeusli of the Keck School of Medicine at the University of Southern California.

The researchers came to this conclusion with a novel salad-mouse model system, which does not immediately make the consumption of superbugs with plant foods ill.

They grew salad. put it out of antibiotic-resistant E. coli, fed it to the mice, and analyzed their stool samples over time.

"We found differences in the ability of bacteria to silently colonize the gut after ingestion, depending on a variety of host and animal bacterial factors," said Maeusli.

"We have mimicked antibiotic and antacid treatments, as both could interfere with the ability of superbugs to survive passage from the stomach to the gut."

To date, little has been done to determine how eaten plants are for the spread of antibiotic-resistant superbugs.

The spread of antibiotic-resistant superbugs from plants to humans differs from outbreaks of diarrheal diseases that occur immediately after eating contaminated vegetables. The intestines for months or even years, when they escape from the intestine and cause an infection, such as urinary inflammation.

"We continue to look for plant traits and host factors that lead to changes in the microbial community in the gut that pose the risk of colonization and those that prevent it," the researchers said at the meeting of the American Society for Microbiology ,
