A study carried out by scientists at California State University, Fresno (CA, USA) have discovered six probiotic Bacillus strains resistant to multiple antibiotics. The work, presented at the 2019 annual conference of the American Society for Microbiology (ASM Microbe, 20–24 June, CA USA), highlights how they used genetic analysis to find antibiotic resistant genes within the strains tested.
Commonly used as probiotics, Bacillus bacterial strains are ‘generally recognized as safe’ by the US FDA and are consumed by people hoping to benefit their health. However, these new findings have indicated that Bacillus may mediate the transfer of antibiotic resistance genes.
