Increasing Temperature Results into Development of Drug Resistant Bacteria

0

Research conducted by University of Toronto revealed that increasing global temperature can boost growth of drug resistant bacteria.

A person living in warmer climates is more prone to drug resistant infections. An increase of 10 degree Celsius can cause bacteria to enhance their ability to resist antibiotics by 3-2%. It was also observed that bacteria grew and reproduced more quickly in warmer temperatures. DNA mutation during reproduction due to increased growth hiked the drug resistance. The research was aided by a large-scale data collection effort to create a free and open web-based application that gives the geographical locations of drug-resistant bacteria.

The team first collected data of antibiotics against various bacterial infections. Escherichia coli, Klebsiella pneumonia, and Staphylococcus aureus were the major drug-resistant strains collected for the study. These strains are said to cause drug resistant infections of urine, skin, and blood. They are highly infectious and can pass from person to person very easily. Over prescription was also a major reason for drug resistance in bacteria. A population density of 10,000 persons per square mile was related to significant rise in the resistance. Overall, temperature, population and prescription rates are all responsible for the growth of drug resistance bacteria.

Recent examples of Zika and Nipah have proved incurable as no drug was successful in restraining the viruses. This has increased risk of more dangerous epidemic diseases in the near future. Increasing global warming and increasing population, is resulting in to high prescription of antibiotics. The study was published by Boston Children’s Hospital in the Daily Science on May 18, 2018
