A strain of Salmonella Newport, found in some beef species in the US and some soft cheeses in Mexico, has been reported by the Center for Disease Control and Antibiotic Resistance Prevention released on Friday.

The CDC reported the results of a study conducted on Salmonella Newport that did not respond to two oral agents commonly recommended for the treatment of Salmonella infections.

Antibiotic resistance in rare cases is Salmonella in humans, although most Salmonella patients do not need antibiotics at all.

For those who do, physicians are concerned that frequently recommended treatments will not be effective in the future if there are more antibiotic-resistant strains. Ian Plumb, epidemiologist in the Department of Enteric Disease Epidemiology of the CDC and author of the study, reported US TODAY.

"Salmonella Newport is one of the most common types of salmonella, which is a major cause of foodborne disease in the United States," said Plumb.

This particular antibiotic-resistant strain was discovered in 2016. said plummet. It has since been detected in cecal and beef samples with a mixture of Queso fresco and Oaxaca cheese in the US and Mexico.

There were 255 cases in the United States last year, spread across 32 states in March 2018 and June 2019.

According to Plumb, the CDC monitors all new cases of infection.

"For infected patients This strain of Salmonella Newport, which needs antibiotic treatment, may need to consider alternative medicines, "said Plumb.

Plumb said that the CDC is concerned that the tribe appears to be reappearing. This means that there could be further antibiotic-resistant infections in the future.

The CDC is not alone in their worries.

Greg Frank, director of Working to Fight AMR, a group fighting against drug-resistant infections, said TODAY the report highlights the importance of antibiotic-resistant infections as a problem faster than we invent new antibiotics and other treatments to fight against them "That said," said Frank.

This questionable stem, found only in beef and soft cheese, has been linked to dairy cows, which is also worrying, Plumb said, as the results suggest that the strain could be spread in cattle.

"We know that every use of antibiotics in humans, animals and the environment can lead to the development and spread of resistant bacteria," said Plumb. The awareness of antibiotic-resistant bacteria that may limit treatment options has increased, Plumb said. In this case, it may be a reminder that antibiotics are considered "precious R Essource ", which should only be used in humans and animals, if necessary.

To avoid salmonella infection when eating beef or cheese, Plumb has some tips:

  • Cook beef at a safe temperature. Ground beef should be cooked at a minimum of 30 ° C and steaks and roasts at a minimum of 30 ° C.
  • Avoid eating soft cheese made from raw (unpasteurized) milk. A label can help you determine when a cheese is "made with pasteurized milk".
