Deadly superhuman epidemic in humans associated with antibiotic spike in cows

Deadly epidemic of many drug resistant salmonella which may have affected 225 people in the beginning of 2018, in the United States triggered by a sharp rise in the use of some antibiotics in cows a year earlier, infectious disease researchers reported this week.

From June 201

8 to March 2019, staff at the Centers for Disease Control and Prevention established an outbreak of Salmonella enterica serotype Newport. The strain is resistant to several antibiotics, most notably azithromycin – a recommended treatment for Salmonella enterica infections. Prior to the outbreak, resistance to azithromycin in this embryo was extremely rare. In fact, it was first seen only in the US in 2016.

Yet, in the 2018-2019 epidemic, it reached at least 225 people in 32 states. Of the patients, at least 60 were hospitalized and two died. (Researchers do not have complete health records for everyone suffering from the epidemic.)

Infectious disease investigators investigating cases trace infections back to beef from the United States and soft cheeses from Mexico (mostly stereo fresco, which is usually is made from unpasteurized milk). Genetic tests show that cows in both countries bear a germ.

In a report released on August 23 by the CDC, investigators note that just a year earlier, the Food and Drug Administration registered a jump in the use of antibiotics, called macrolides by livestock farmers. From 2016 to 2017, breeders increased the use of macrolide antibiotics by 41%. Macrolides are a class of antibiotics that includes azithromycin. Because antibiotics in the classroom work to kill bacteria in similar ways, bacterial resistance to one drug in a class can lead to resistance to other drugs in the same class.

Researchers suggest that an increase in macrolide use could promote the increase and spread of the Azortromycin-resistant Newport strain.

"Because the use of antibiotics in livestock can cause selection of resistant strains, a reported increase of 41% Use of macrolides in cattle in the United States from 2016 to 2017 may accelerate the outbreak of outbreaks of cattle in the United States, "they write.

" Avoiding the unnecessary use of antibiotics in cattle, especially those that are important for the treatment of human infections, can help prevent the spread of [multi-drug resistant] Newport with reduced susceptibility to azithromycin. "

] In recent years about 70% o all medically important antibiotics in the US have been marketed for use in animals Public health advocates say antibiotic use in agriculture needs to be significantly reduced to maintain the effectiveness of drugs

To reduce the risk of infection – drug-resistant or not – health officials advise consumers not to eat cheese made from unpasteurized milk and to make safe beef reaches safe cooking temperatures: 145 ° F (62.8 ° C) for steaks, and Chaney, followed by 3-minute rest period and a 160 ° F (71,1 ° C) for ground beef or hamburger.
