Different probiotic strains can be resistant to different antibiotics

In February 2020 researchers from India published the results of their study to assess the antibiotic resistance in commercially available dietary and probiotic supplements or in other words, the ability of a probiotic strain to resist the effects of an antibiotic. Probiotic strains were isolated from the dietary supplements and tested against different antibiotics. Results showed that probiotic strains Enterococcus faecalis (formerly known as Streptococcus faecalis) and Bacillus mesentericus were resistant to penicillin G, Lactobacillus acidophilus was resistant to ampicillin, Lactobacillus sporogenes, E. faecalis , B. mesentericus, Lactobacillus rhamnosus, Saccharomyces boulardi and L. sporogenes were resistant to erythromycin. All the probiotic strains tested were resistant to ceftazidime.
