The antimicrobial activity of honey produced by Melipona asilvai, Melipona quadrifasciata anthidioides, Friseomelita doederleinei, Tetragonisca angustula and Plebeia sp. were investigated. The agar well diffusion assay demonstrated that all honeys had antibacterial activity against Staphylococcus aureus, but only the samples from M. quadrifasciata anthidioides and F. doederleinei inhibited the growth of Escherichia coli. In the Minimum Inhibitory Concentration determination assay, M. asilvai, M. quadrifasciata anthidioides, F. doederleinei and T. angustula honeys were more active than that from Plebeia sp. for S. aureus and E. coli. The microorganisms Pseudomonas aeruginosa and Candida albicans were resistant to the all native stingless bee honeys in both assays. Honeys were more effective against bacteria than a sugar solution, suggesting that the mechanism for bacterial growth inhibition is not only related to the osmotic effect. The results of antimicrobial activity may explain t...
Abstract The antimicrobial activity of honey depends on many factors, including its botanical origin, geographical and entomological source. The aim of this study was to evaluate and compare the antimicrobial potential of honey varieties from Apis mellifera, Hypotrigona sp. and Melipona sp. against MDR Staphylococcus aureus, Bacillus cereus, Escherichia coli, Pseudomonas aeruginosa ATCC 25783, Candida tropicalis, Candida albicans SC 5314 and Cryptococcus neoformans. By using standard microbiological procedure, the agar-well diffusion and broth microdilution methods were used to evaluate honey samples for their antimicrobial and non-peroxidase activity. Different concentrations of the honey samples showed inhibition zones diameter (mm) against the test isolates. The Minimum Inhibitory Concentrations (MICs) of the honey varieties from A. mellifera, Hypotrigona sp. and Melipona sp. ranged from 6.3–25.0%, 3.1–12.5% and 6.3–25.0% (v/v) respectively. There were no statistically significant differences between the mean MICs of honey varieties against E. coli, P. aeruginosa (ATCC 25783) and C. neoformans. Hypotrigona sp. honey had the least mean MICs (4.15 ± 1.58–11.11 ± 2.76 % v/v) against most of the test organisms. The Minimum Biocidal Concentration (MBC) of the honey varieties from A. mellifera, Hypotrigona sp. and Melipona sp. against the test organisms varied from 6.3–50%, 3.1–25% and 12–50% (v/v) respectively. There were no significant differences between the mean MBCs of the honeys against MDR S. aureus (p=0.179), E. coli (p=0.564), P. aeruginosa (ATCC 25783) (p=0.846), and C. albicans (SC5314) (p=0.264). The honeys had some levels of non-peroxidase activity against E. coli, P. aeruginosa (ATCC 25783) and C. neoformans. This study has scientifically authenticated the potential use of stingless bee honeys from “Okotobo and Ifufu” as complementary therapeutic agents.

Antimicrobial activity of honey has lately drawn researchers' attention, especially due to the fact that its antimicrobial capacity has been proven. The aim of this study was analyzing bactericidal and bacteriostatic action in the pathogenic microorganisms Staphylococcus aureus, Escherichia coli and Candida albicans of honey samples from five regions of the state of Paraná. Candida albicans yeast showed to be more resistant to honey than the bacteria Escherichia coli and Staphylococcus aureus. The minimal inhibitory concentration found for the three microorganisms tested was 12.5% to 25%. The minimal bactericidal concentration, in its turn, was 25% for bacteria and 25% to 50% for yeast. The samples from the Southern area had the best results for both the minimal inhibitory and the bactericidal concentrations. Through physicochemical and phyto-chemical analysis, we observed that several factors are associated to the bactericidal capacity of honey. In conclusion, honey is an excellent bactericidal agent with a great biotechnological potential. Its properties are directly related to its geographic origin, which gives each type of honey its own characteristics.

Honey is a functional food used worldwide and recognized for its multiple health benefits. In the present study, the physicochemical and antioxidant properties of honey produced by two species of bees (Melipona eburnea and Apis mellifera) in two seasons were evaluated. In addition, the antimicrobial activity of honey against three bacterial strains was studied. The quality of honey analyzed by LDA (linear discriminant analysis) showed four clusters mediated by the interaction, the bee species, and the collection season resulting from a multivariate function of discrimination. The physicochemical properties of the honey produced by A. mellifera met the requirements of the Codex Alimentarius, while the M. eburnea honey had moisture values outside the established ranges of the Codex. Antioxidant activity was higher in the honey of A. mellifera, and both kinds of honey showed inhibitory activity against S. typhimurium ATCC 14028 and L. monocytogenes ATCC 9118. E. coli ATCC 25922 showed ...

One of the serious problems the world is facing today is the antimicrobial resistance on available antibiotics by most bacterial pathogens and the rising cost of finding effective antimicrobial agents. In recent years, efforts to find new drugs especially from natural sources have been boosted by the demand for an effective cure for infectious diseases. Only the antibacterial activity of apis mellifera honey and not stingless bee honey from western Kenya has been reported. This study was therefore carried out to determine the effect of Plebenia hylderbrandii and Meliponula bocandei honey samples on the growth of control; sensitive cases of Escherichia coli (ATCC 25922) and Staphylococcus aureus (ATCC 25923). Different honey concentrations (1.18%-17.65% v/v) of the two samples were tested against the two microorganisms. The samples were screened for their antibacterial potential against Escherichia coli and Staphylococcus aureus by agar well dilution method. The Partial inhibitory concentration (PIC), minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values were determined by in vitro method. The inhibitory effect of Plebenia hylderbrandii honey on E. coli and S. aureus growth was apparent at concentrations 3.53% and 1.76% (v/v) respectively. On the other hand, the inhibitory effect of Meliponula bocandei honey on S. aureus growth was at concentration 16.47% (v/v).

This study aimed to assess the antimicrobial activity of various honeys against strains of gram-negative and -positive bacteria, as well as to determine the physicochemical parameters of these honeys. Seven honeys from various species of stingless bees were evaluated. The physical-chemical parameters evaluated were pH, moisture, water activity, acidity, ash, electrical conductivity and color. Antimicrobial activity was determined using disc diffusion agar tests and minimum inhibitory concentrations. We found that there was a relationship between the physical-chemical parameters and the antimicrobial activity. The minimum inhibitory concentration of 25% honey was able to inhibit the growth of both gram-positive and -negative bacteria; the greatest efficacy was verified for the species of bees Melipona mondury, M. quadrifasciata, Scaptotrigona bipunctata and Tetragona clavipes. Regarding synergism, Escherichia coli maintained its sensitivity profile in relation to all studied honeys c...

Antimicrobial Potential of Honey Samples of Apis cerana indica
Honey is an ancient remedy for the treatment of infected wounds, which has recently been rediscovered by the medical profession, particularly where conventional modern therapeutic agents are failing . Honey samples were collected from two different geographical regions , i.e Hill (kodaikkanal) and plain (Mannargudi) . The antimicrobial activity of honey was performed by well diffusion assay against pathogens i.e, bacteria [Bacillus subtilis, Bacillus cereus, Pseudomonas aeruginosa Enterobacter aerogenes, klebsiella], Fungi [Aspergillus niger, Aspergillus flavus, Trichoderma viride], yeast [Saccharomyces cerevisiae, candida], Actinomycetes [Streptomyces] and antibiotic sensitivity test was also performed for these pathogens using some antibiotics [Gentamycin, Auxamine, Tetracycline, Ampicillin].

Scientific studies about the antibacterial effects of honeydew honey produced by the stingless bee are very limited. In this study, the antibacterial activities of 46 blossom and honeydew honeys produced by both honey bees and stingless bees were evaluated and compared. All bacterial isolates showed varying degrees of susceptibility to blossom and honeydew honeys produced by the honey bee (Apis cerana) and stingless bee (Heterotrigona itama and Geniotrigona thoracica) in agar-well diffusion. All stingless bee honeys managed to inhibit all the isolates but only four out of 23 honey bee honeys achieved that. In comparison with Staphylococcus aureus, Escherichia coli was found to be more susceptible to the antibacterial effects of honey. Bactericidal effects of stingless bee honeys on E. coli were determined with the measurement of endotoxins released due to cell lysis. Based on the outcomes, the greatest antibacterial effects were observed in honeydew honey produced by H. itama. Scann...
