Friday, September 9, 2016 (HealthDay News)-Scientists identify new patients with types of bacteria that are resistant to antibiotics as a last resort, reducing the number of cases reported in the United States to four I increased it.
Maroya Spalding Walters, a senior researcher at the CDC epidemiologist, said the latest case, a 2-year-old Connecticut girl, was diagnosed in June after returning from a trip to the Caribbean. ..
“The girl caused the illness diarrhea, Started during an overseas trip in mid-June.she diarrhea The cause was not the bacteria that carried the mcr-1 gene-the cause has not been clearly diagnosed, “she said.
The mcr-1 gene was found but did not produce toxins. When the girl got better, the bacteria that contained the gene disappeared within a week of her recovery, Walters said.
Similar cases have been reported in Pennsylvania and New York.
Fortunately, none of these infections have spread beyond the original patient, Walters said.
Still, she added that mcr-1 is resistant to colistin, which is reserved for the treatment of severe infections that are resistant to other antibiotics.
“I’ve seen colistin resistance in the past, but what makes this mcr-1 gene so important is that it can be transmitted between different types of bacteria,” Walters explained.
“The concern is that we’re already very resistant and can move to bacteria that can make them resistant to all antibiotics, but we haven’t confirmed this in the United States,” she said. rice field.
But it has also been seen in other parts of the world. Walters said mcr-1 itself is sensitive to many other antibiotics.
E. coli containing the mcr-1 gene has been found in livestock, according to Walters, but it’s not clear how people get the bacteria. It has also been found in hospitals and can be transmitted in that environment.
E. coli The use of the mcr-1 gene is still rare in the United States, but “but that’s what we’re looking for,” Walters said.
“I’m not going to stop the spread of mcr-1 altogether, but I want to limit it,” she said. The idea is to track it. So far, it hasn’t progressed from person to person, she added.
“Bacteria continue to develop new forms of resistance, so we must preserve the antibiotics we have by not overusing them,” Walters said.
The findings were published on September 9th at the CDC Weekly morbidity and mortality reports..
