Background: So far there have been no reports about lactobacilli in honey samples and their probiotic properties in Iran. The aim of this study is identification of Lactobacillus plantarum and Lactobacillus paracasei strains in Iranian honey samples and investigation of probiotic and antimicrobial effects of them against staphylococcus aureus.
Methods: This cross-sectional study investigated 88 honey samples from different areas in Iran at 6 months, from May to September, 2016. Samples were enriched in MRS broth and after were cultured on MRS agar. Lactobacillus isolates were identified to the species level by 16S rDNA gene sequencing method. Probiotic tests such as tolerance to acid and bile were done.  Antimicrobial activity and antibiotic resistance of isolates were evaluated by agar well diffusion and disk diffusion method respectively.
Findings: From 88 honey samples, 39 Lactobacillus isolates were identified and from these isolates, four L. plantarum and two L. paracasei were identified by molecular technique. Every six isolates tolerated acidity but sensitive to bile salt. Five isolates inhibited the growth of S. aureus. The most antibiotic resistance of Lactobacillus strains was seen to vancomycin, nalidixic acid and streptomycin.
Conclusion:  Iranian honey samples can be a good source for different Lactobacillus species as L. plantarum and L. paracasei which some of these species could have wonderful inhibitory effects against pathogen bacteria like S. aureus.
