Research lead by a team from the University of Canterbury, New Zealand has found that commonly used herbicides, including the worlds most used herbicide Roundup, can cause bacteria to become resistant to antibiotics.
This is the first study of its kind in the world.
The team at the University of Canterbury investigated what happens to species of disease-causing bacteria when they are exposed to common herbicides such as Roundup, Kamba and 2,4-D.
We found that exposure to some very common herbicides can cause bacteria to change their response to antibiotics. They often become antibiotic resistant, but we also saw increased susceptibility or no effect. In most cases, we saw increased resistance even to important clinical antibiotics, Professor Heinemann says.
We were so surprised by what we were seeing. We wanted to be sure it wasnt an artefact of conditions in our laboratory or some kind of contamination. So we enlisted a fellow researcher at Massey who conducted the same experiments but without knowing what she was adding to the bacteria. She got the same results. …read the rest of article
