HIGHLIGHTS

  • Bacteria have almost universally developed resistance to drugs such as amoxcillin and cefoperazone, which is seen in the figures for Jakkur and Bellandur.
  • Take, for instance, Citrobacter species, which can cause a wide spectrum of infections from urinary tract to the respiratory tract, has resistance to six drugs in Jakkur lake.
  • The research first took root in identifying common antibiotics present in significant quantities.

 

 In a comparison of 10 bacterial species with 10 common antibiotics, researchers found that in Jakkur lake, bacteria had developed resistance in 37 cases; that is, each bacteria species developed resistance to between one and six antibiotic drugs. However, in Bellandur, this number goes up to 51.

Bacteria have almost universally developed resistance to drugs such as amoxcillin and cefoperazone, which is seen in the figures for Jakkur and Bellandur. But it is the variation of the other drugs that is a concern, said Mr. Mahesha.

Take, for instance, Citrobacter species, which can cause a wide spectrum of infections from urinary tract to the respiratory tract, has resistance to six drugs in Jakkur lake. At Bellandur, it has resistance to eight drugs. Klebsiella, which can cause pneumonia, has seen resistance to seven drugs in Bellandur, compared to five in Jakkur.

The research first took root in identifying common antibiotics present in significant quantities. In 2017, Ms. Jamwal and researchers from Portsmouth in the UK deployed Chemcatcher, a novel technology that can find out medical compounds present in water and their concentrations.

Their tests in Jakkur lake, Vrishabhavathi valley and sewage flowing out of two apartment complexes showed the presence of antibiotics, antidepressants, antifungals, antihistamines, anti-inflammatory, epilepsy, beta-blockers and painkillers in the water.
