Antibiotic resistance to antibiotics has soared in livestock worldwide

countries such as India are becoming more resistant to commonly used antimicrobials as meat production increases in developing countries, a worrying trend, researchers have reported.
kenya, Uruguay and Brazil have also seen drug resistance hotspots, according to a study of antibiotic resistance in livestock in Asia, Africa and South America. Meat production in these areas has risen sharply since 2000, thanks to more intensive agricultural production methods, including the use of antibiotics in animals to promote growth and prevent infection.
scientists report the findings in the September 19 issue of the American journal Science.
Thomas Van Boeckel, an epidemiologist at the Swiss Federal Institute of Technology and co-author of the study, said: "For the first time, we have some evidence that antibiotic resistance is on the rise, a sign that is more pronounced in low- and middle-income countries. He said governments should take action to address the growing threat and coordinate their efforts globally.
To study how resistance evolved over time, Van Boeckel and his colleagues analyzed 901 epidemiological studies in developing countries that focused on four common bacteria - salmonella, Campylobacter, Staphylococcus aelobacter and E. coli. Using this information, the researchers mapped the areas where multidring resistance exists and where multidrring resistance is beginning to appear.
their findings also show that four antimicrobial drugs most commonly used on farms to gain weight for livestock - cyclocycline, sulfonamide, quinoxone and penicillin - are also the drugs that produce the highest antibiotic resistance.
from 2000 to 2018, the proportion of bacteria resistant to drugs nearly tripled in chickens and pigs and tripled in cattle.
Amabile-Cuevas, a microbiologist at the Lusala Foundation in Mexico City, said the situation is serious because countries with drug-resistant hotspots export thousands of tons of meat products each year. The Lusara Foundation is an organization that specializes in antibiotic resistance research. About one-half of chickens and pigs are raised in countries that have found drug-resistant hotspots.
even if governments take steps to control the use of antibiotics in farm animals, these efforts are likely to be scaled down if they do not import food that meets the same production standards. "This issue has nothing to do with political boundaries." Amabile-Cuevas said.
Van Boeckel says high-income countries, which have been using antibiotics in livestock since the 1950s, should now subsidize safer agricultural production in some parts of the world where antibiotic resistance is on the rise.
"We have a lot of responsibility for the global problems that we have caused." Van Boeckel said, "If we want to help ourselves, we should help others first."
resistance to antibiotics is a type of resistance that refers to organisms (especially pathogenic microorganisms) that were previously sensitive to an antibiotic and, after mutation, develop characteristics that are highly resistant to them. Drug-resistant mutations can occur on both nuclear chromosome genes and on protons. This type of prosurloy will be transferred between different strains or strains, the prevention and treatment of infectious diseases is extremely harmful. (Source: China Science Journal Zhao Xixi)
