Dr. Hua Wang, associated professor of food science and technology at Ohio State University presented her talk on drug resistances A recent study conducted by Wang and her colleagues found that the bacteria that go into the body without causing harm might greatly contribute to the spread of drug resistant genes. Other studies have backed up that conclusion, Wang said.
“These studies show that antibiotic-resistant bacteria can persist even without direct exposure to antibiotics in the host’s system,” she said.
Scientists are having a hard time getting access to farms to study drug resistance among livestock. Instead, Wang and her team chose to collaborate with the cheese industry to get access to production facilities where they could measure for drug resistance along critical control points.
Once they found the points that made the biggest difference in the presence of drug resistance bacteria, they made a number of recommendations to the cheese industry. By following these recommendations, the industry removed drug resistance strains and reduced the drug resistance gene pool significantly.
“It is important to recognize that prudent use of antibiotics does not mean a ban of use or not use,” Wang said, “but knowing what, when, and how to use the antibiotics.”
In another realm, scientists are finding that drug resistance bacterial genes can be passed from the mother onto her newborn child. Infants never directly exposed to antibiotics can be shown to harbor bacteria with drug resistance genes immediately after birth.
