High levels of antibiotic resistance found globally

Thursday, February 1, 2018

Data on antibiotic resistance reveals high levels of resistance to a number of serious bacterial infections in both high- and low-income countries.

WHO’s new Global Antimicrobial Surveillance System (GLASS) reveals widespread occurrence of antibiotic resistance among 500, 000 people with suspected bacterial infections across 22 countries.

The most commonly reported resistant bacteria were Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus, and Streptococcus pneumoniae, followed by Salmonella spp.

Among patients with suspected bloodstream infection, the proportion that had bacteria resistant to at least one of the most commonly used antibiotics ranged tremendously between different countries – from zero to 82 per cent. Resistance to penicillin – the medicine used for decades worldwide to treat pneumonia – ranged from zero to 51 per cent among reporting countries. And between 8 per cent to 65 per cent of E. coli associated with urinary tract infections presented resistance to ciprofloxacin, an antibiotic commonly used to treat this condition.

“The report confirms the serious situation of antibiotic resistance worldwide,” says Dr. Marc Sprenger, director of WHO’s Antimicrobial Resistance Secretariat. “Some of the world’s most common – and potentially most dangerous – infections are proving drug-resistant. And most worrying of all, pathogens don’t respect national borders. That’s why WHO is encouraging all countries to set up good surveillance systems for detecting drug resistance that can provide data to this global system.”

The report is a vital first step towards improving our understanding of the extent of antimicrobial resistance.
