San Francisco: Not only animal meat, but also plant foods serve as a means of transport for the transfer of antibiotic-resistant bacteria to the intestinal microbiome of humans, warn researchers.
The United States Centers for Disease Control and Prevention estimate that 20 percent of the two million antibiotic-resistant infections in the country each year are related to agriculture.
This estimate is based on patients who directly purchase antibiotic-resistant superbugs from the consumption of meat.
"Our findings underscore the importance To draw this conclusion, researchers Marlene Maeusli from the Keck School of Medicine at the University of Southern California have stated that antibiotic resistance that is transmitted by food is from the perspective of a complete food chain , which includes meat as well as plant foods, should be combated.
developed a novel lettuce mouse model system that does not immediately make the consumption of superbugs with plant foods ill.
They planted lettuce and planted it against antibiotic-resistant E. coli, fed it to the mice, and analyzed their fecal samples for an extended period of time.
"We found differences in the ability of bacteria to settle silently after ingestion, depending on a variety of host and bacterial factors." We have mimicked antibiotic and antacid treatments, as both could affect the ability of superbugs to survive the passage from the stomach to the intestine. " 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.
Superbugs can hide asymptomatically in the gut or "colonize" them for months or even years, when they then escape from the gut and trigger an infection such as a urinary tract infection.
cs and host factors that lead to changes in the intestinal microbial community that pose a risk to colonization and those that prevent it, "the researchers said at the meeting of the American Society for Microbiology.
