Antibiotic-resistant salmonella strain moves from China to U.S.
June 14 (UPI) -- The gene that makes salmonella resistant to antibiotics of last resort has finally made its way from Asia to the United States, a new study says. Researchers isolated the gene mcr-3.1 in a patient who had traveled to China two weeks before falling ill to salmonella, according to research published in the June edition of the Journal of Medical Microbiology. They found the gene after genome sequencing 100 human stool samples collected between 2014 and 2016. "This gene was already in the USA since 2016, which is surprising," Siddhartha Thakur, the director of global public health at North Carolina State University, told UPI. "Colistin is the last resort drug and if the gene for resistance jumps on a plasmid then it spreads faster." According to Thakur, the gene made its way...
