‘Bloodstream infection bacteria grew resistant to last-resort drugs in 2020’

LONDON: Increased drug resistance in bacteria causing bloodstream infections, including against last-resort antibiotics, was seen in the first year of the coronavirus pandemic, a World Health Organisation report based on data from 87 countries in 2020 showed.

The overuse and/or misuse of antibiotics has helped microbes to become resistant to many treatments, while the pipeline of replacement therapies in development is alarmingly sparse. High levels (above 50%) of resistance have been reported in bacteria that typically cause life-threatening bloodstream infections in hospitals such as Klebsiella pneumoniae and Acinetobacter spp, report authors highlighted today. These infections often require treatment with ‘last-resort’ antibiotics, drugs that are used when all other antibiotics fail.

About 8% of bloodstream infections caused by Klebsiella pneumoniae grew resistant to a vital last-resort group of drugs called carbapenems, the report said. Rates of antimicrobial resistance (AMR) remain very high, but last-resort antibiotics are only just starting to lose potency, said Dr Carmem Pessoa-Silva, the lead for WHO Global Antimicrobial Resistance Surveillance System, in a media conference.
