Cancer causing bacteria gains antibiotic resistance, find scientists

MANIPAL: A bacterium which causes stomach cancer has gained resistance to three commonly used antibiotics, according to a study by the Kasturba Medical College of Manipal Academy of Higher Education.

The study by the Kasturba Medical College of Manipal Academy of Higher Education (MAHE) and tertiary care hospital, said to be first of its kind from Karnataka, has found that Helicobacter Pylori, a bacterium that resides in the human stomach and causes ulcers, gastritis and stomach cancers, has gained resistance to three commonly used antibiotics – metronidazole, levofloxacin and clarithromycin.

So, now these drugs may not be able to provide relief anymore.

This important finding was the result of the joint collaboration of KMC, MAHE Scientists and scientists from Marshall Centre, The University of Western Australia. The KMC scientists involved in the study were Dr Mamatha Ballal (Team Lead), Dr Vignesh Shetty, Dr Ganesh Pai, Dr Ramachandra L, Dr Shiran Shetty and the UWA Scientists: Dr Alfred Tay, Dr Eng Guan Chua and Binit Lamichhane.

The study was aimed to gain insight on the prevalence and mechanism of drug resistance in Helicobacter linked diseases so as to help develop strategies with more rational antibiotic combinations for treatment. This will also help implement precise therapy and thus prevent recurrence of the infections.

This study can act as a strong foundation to progress in national epidemiological surveillance which will be beneficial in evidence-based treatment and also as a managerial follow-up of eradication of Helicobacter if the first line treatment fails. The working group at KMC in future plans to come out with a rapid kit for detection of drug resistance in bacteria, which would help clinicians to modulate treatment regimen.
