Rising global temperatures have led to bacteria becoming more resistant to antibiotics.

Beijing, June 27 , according to foreign media reports, the latest research of scientists, as the global temperature gradually rise, may lead to bacteria more resistant to antibiotics.
Tom Patterson, who fell ill while on holiday in Egypt in 2015, contracted Acinetobacter baumannii, a deadly bacteria that is resistant to every antibiotic doctor tries.
Patterson, a professor of psychiatry at the University of California, San Diego, initially thought he might have died from the infection, but did not.
researchers experimented with a phage that ultimately saved his life.
he experienced a near-death experience in warmer-temperature Egypt, where a large number of soldiers and wounded in Iraq and Kuwait were also said to have been infected with the virus.
these cases have raised the attention of scientists who believe that viral resistance is closely linked to rising global temperatures. Robert T. Schooley, an infectious disease specialist at the University of
at the University of California, San Diego, said: "Travelers from the tropics will carry more drug-resistant pathogens, which pose a serious challenge to antibiotic strains in existing pharmacies.
at the same time, raising the temperature of the baby incubator will significantly accelerate the evolutionary clock of bacteria and other pathogens that coexist with us.
"Experts now know that climate change is a major threat to global public health, especially as temperatures rise and the number of insects that transmit diseases such as mosquitoes increases."
, rising temperatures will also boost bacterial growth, provide them with the opportunity to mutate, and become resistant to drugs that kill them.
While viral resistance is thought to be largely due to human misuse of antibiotics, experts now believe other environmental pressures, including climate change, may also be linked to increased viral resistance.
global populations are now facing an increasing and more deadly number of multidrug-resistant viral infections, many of which are difficult to treat or incur.
the World Health Organization (WHO) describes the situation as "one of the greatest threats to global health, food security and development today".
the U.S. Centers for Disease Control and Prevention (CDCP) statistics show that there are more than 2 million cases of drug-resistant viral infections in the United States each year, leading to an average of about 23,000 deaths per year. a recent study published in the journal Nature Climate Change,
, shows that climate change is closely linked to bacterial resistance in the United States, particularly in the southern United States.
epidemiologists at Boston Children's Hospital and the University of Toronto found that higher local temperatures and higher population density, the stronger resistance of some common bacterial strains. "To date, most of the climate's effects on communicable diseases have been concentrated in vector-borne and diarrhoeal diseases, but our research suggests that climate change may have a significant impact on viral resistance," said Derek MacFadden, lead author of the
study and a researcher at Boston Children's Hospital.
if that is the case, as global warming trends intensify over time, antibiotic resistance will change much more than previously thought, and the impact of climate factors is likely to have been underestimated.
in the study, they evaluated a variety of sources in the U.S. database for 2013-2015 to collect information on viral resistance related to E. coli, Streptococcus pneumoniae and Staphylococcus aureus.
their data were recorded in 602 cases at 223 medical facilities in 41 U.S. states, all taken from infected patients.
they then compared the data with latitude coordinates, as well as regional temperature averages and medians, and found that the higher the local average minimum temperature, the stronger the resistance of the local virus.
studies show that the local average minimum temperature rises by 10 degrees Celsius, and the peak of E. coli, Streptococcus pneumoniae and Staphylococcus aureus resistance increases by 4.2%, 2.2% and 3.6%, respectively.
, they also found that by adding 10,000 people per square mile, the peak of resistance to E. coli and Streptococcus pneumoniae would increase by 3 percent and 6 percent, respectively, suggesting that population density is also closely related to viral resistance. "Population growth, rising temperatures and increased viral resistance are three important phenomena that are happening on Earth today," said Mauricio Santillana, co-author of the study
and a member of the Computational Health Informatics Program at Boston Children's Hospital.
But so far there has been little assumption about how these phenomena are interrelated, and we need to continue to work with interdisciplinary teams to study drug resistance in the context of demographic and environmental change.
the study also found that local residents also used higher prescriptions for antibiotics in geographic regions where viral resistance increased.
McFadden said that while the study showed that viral resistance was particularly acute in the hot southern regions, he warned that no part of the United States was safe.
if temperature plays an important role in viral resistance, the effect sits anywhere, especially in areas where temperature changes the most over time, especially in the polar regions. Scully, who
from the University of California, San Diego, who was not involved in the study, said any number of biological factors could be affected by viral resistance.
as temperatures rise, the overall number of bacteria in the environment increases, and the spread of bacterial resistance genes increases, and the interaction of animal populations changes from a health perspective.
Scully stressed that a 10-degree change in the minimum temperature is a big challenge for climate studies, as experts often discuss a 6 degree Celsius change in the global average temperature by the end of the century.
but the human behaviour of those who ignore the potential effects of climate change and put the planet at risk is worth pondering.
we have now found some correlations, more needs to be done to confirm the consistency and possible mechanisms of the study in different regions. John Brownstein, another senior co-author of the
and director of the epidemiology team at Boston Children's Hospital, said public health assessments now predict a dangerous escalation of viral resistance in the coming years, climate change will accelerate viral resistance and the future will be worse than expected.
