"Human feces may often explain the existence of antibiotic-resistant bacteria in the environment."
"It shows a study by researchers at the Sahlgrenska academy at Göteborg university."
"There is a great concern to more and more bacteria are becoming resistant to antibiotics and there are several theories about the causes. That the environment has a role, many believe, but the new study, published in the journal Nature Communications on Tuesday, shows that most resistant bacteria in the environment seems to come directly from human feces."
"– the Presence of resistant bacteria in the environment correlates very well with the presence of a particular bacterial virus that is only found in human intestinal bacteria, " says Joakim Larsson, a professor in the miljöfarmakologi, and one of the authors behind the study."
"the Scientists conclude therefore that the presence of resistant bacteria in the environment depends to a great extent on human feces. It explains that the prevalence of resistant bacteria is much more common in other parts of the world where you do not purify sewage, but human feces are taken directly out of nature."
"Even pharmaceutical industries"
"It is the human use of antibiotics has caused bacteria in the intestine, and consequently in our stools have become more resistant. But human feces is not the only cause resistant bacteria."
"– There are environments that have high levels of antibiotics, for example outside the pharmaceutical industries. There is not much bowel movement but still very large incidence of resistant bacteria, " says Joakim Larsson."
" Where have the antibiotics has given the bacteria an advantage and are likely to provoke new forms of resistance."
"Still, there are areas left that need to be explored more."
"We need more research to find out what low levels of antibiotics in the environment means," says Joakim Larsson, and referring in particular to the antibiotics which are excreted in the pee and poop and reaches the environment via our toilets and sewage treatment plants."
"Antibiotic resistance means that a microorganism, usually a bacterium, developed resistance to the antibiotics, drugs which are bactericidal or inhibit bacterial growth."
"Of all the bacteria are genetic variants, some of which are more resistant to antibiotikans effects than others."
"Resistance develops when these variants are favored by natural selection and become dominant in the bakteriestammen, which occurs when antibiotics are used."
"the Risk of resistance arising is reduced if antibiotics are not used unnecessarily, and if the bacteria are not exposed to too low or short-term doses."
