To query ProbResist database, enter the species, antibiotic or region name

    Please use the abbreviated forms of the bacteria in the search. B. = Bacillus; Bb. = Bifidobacterium; Bv. = Butyrivibrio; Ec. = Enterococcus; Lb. = Lactobacillus; Lc. = Lactococcus; Ln. = Leuconostoc; Oc. = Oenococcus; Pc. = Pediococcus; Sc. = Streptococcus; W. = Weissela

    Since April 2020, the Lactobacillus genus is reclassified into more than 25 genera, including 23 novel genera. The new names of prominent Lactobacillus probiotic species are as follows: Lb. casei = Lacticaseibacillus casei; Lb. paracasei = Lacticaseibacillus paracasei; Lb. rhamnosus = Lacticaseibacillus rhamnosus; Lb. plantarum = Lactiplantibacillus plantarum; Lb. brevis = Levilactobacillus brevis; Lb. salivarius = Ligilactobacillus salivarius; Lb. fermentum = Limosilactobacillus fermentum; Lb. reuteri = Limosilactobacillus reuteri

    Please use the full names (e.g., Lacticaseibacillus casei or Limosilactobacillus reuteri) of the bacteria when searching for newer articles that contain the new Lactobacillus probiotic names. For further information on Lactobacillus taxonomy changes, please refer to the ISAPP announcement, or the published article


    Probiotics are live microorganisms capable of conferring health benefits to the host if consumed in adequate amounts. Due to their overwhelming health benefits, probiotic bacteria have been included in numerous foods, dietary supplements, and health products. It is well-documented that probiotics harbor resistant determinants that can through horizontal gene transfer, accumulate in commensals of the human gut or oral cavity and risk acquisition by opportunistic pathogens, thus rendering antibiotic treatments ineffective. This database catalog probiotic bacteria from various sources that have been reported to be resistant to antibiotics.
