Global Action Against Antimicrobial Resistance (AMR): L-forms, How to Recognize Them Under the Optical Microscope

The Lancet published a systematic review of the global burden of bacterial antimicrobial resistance in 2019, which found a worrying increase. In 2017, World Health Organization (WHO) published a list of priority antibiotic-resistant pathogens, which included the 12 most dangerous bacterial families for human health. We would like to draw attention to the L-forms that are poorly understood at the clinical level in hospital laboratories and have great potential to improve diagnosis and avoid underdiagnosis.
