“…The present results are on line with those re-ported by Mekky (2007) who studied that, un-processed honey was inoculated with toxigenic strains of Aspergillus flavus and A. parasiticus. The fungi grew and sporulated in varying amounts of honey diluted with water, but none of the cultures produced detectable levels of aflatoxin.…”

Serial concentrations of three unprocessed honey (mountain; nuwara clover and citrus) samples from Egypt, were evaluated for their ability to act as antimicrobial activity against fifteen fungal species including toxigenic strains of Aspergillus flavus and A. parasiticus and four Gram positive and five Gram negative pathogenic bacterial isolates. Also, investigation of inhibitory action of aflatoxins production by A. flavus and A. parasiticus was studied. 90% and 100% concentrations of three honeys used, exhibited high ability to inhibit the growth of most of fungal and bacterial isolates. Mountain honey was the best honey. It showed antimicrobial activity followed by citrus then nuwara clover honey. However, 80% concentration from only mountain honey showed antimicrobial activity while all other honey concentrations prepared did not show any ability to reduce the growth of all fungal and bacterial isolates tested. As well as, no aflatoxins were produced at 100% concentration of three honeys used, while great reduction of aflatoxins production was detected after treatment with 90% concentration of all honeys. Moderated effect on toxins production was reported by 80% concentration and little inhibition was obtained at 70% honey concentration. Other honey concentrations (10% to 60%) showed opposite effect on aflatoxins production, where the amounts of toxins were increased. Mountain honey was the best, which showed ability to inhibit the production of aflatoxins by both of A. flavus and A. parasiticus followed by nuwara clover then citrus honey.

“…Honey possesses powerful antimicrobial properties that can be utilized at low cost and at no risk. Various studies have reported the antimicrobial activities of honey (Asadi-Pooya et al, 2002;Al-Waili, 2004;Agbaje et al, 2006;Chambers, 2006;Vilma et al, 2007;Mekky, 2007;Israili, 2014). The intrinsic properties of honey have been reported to affect the growth and survival of microorganisms by bacteriostatic or bactericidal actions (Iurlina and Fritz, 2005).…”

Honey samples from three different ecozones - coastal freshwater (Ogba), lowland rainforest (Oka-Akoko) and montane Sudan savanna (Mambilla plateau) – were subjected to melissopalynological, proximate and elemental analyses, as well as antimicrobial studies. The aim of the research was to determine the contribution of pollen, if any, in the antimicrobial activities of the studied honey samples. Standard preparation methods were adopted for these studies. The Mambilla honey recorded the highest pollen diversity, while that of Oka-Akoko and Ogba regions had similar diversity, both having lower values. The Ogba honey however contained the highest abundance of pollen. Proximate analysis showed that the Mambilla honey also recorded the highest values of moisture, ash, protein, fats and oil, as well as potassium and reducing sugars. Antimicrobial investigation revealed the highest antimicrobial activities for the Mambilla honey, followed by Oka-Akoko and Ogba against Staphylococcus aureus (gram positive) and Pseudomonas aeruginosa (gram negative). Moisture content, proteins and carbohydrates were significantly different, with positive and negative trends respectively, when related with the antimicrobial activities of the honey samples. The pollen contents were also qualitatively different. This is the first time the antimicrobial activity of honey is ever traced to pollen contents. More conclusions can be accurately made only after further research upon pollen grains directly.

“…Various studies have reported the antimicrobial activity of honey (Agbaje et al, 2006;Patten et al, 2006;Vilma et al, 2007). Honey has been shown by Mekky (2007) to inhibit the growth of Aspergillus flavus and reduce aflatoxin B 1 and B 2 levels. The intrinsic properties of honey have been reported to affect the growth and survival of microorganisms by bacteriostatic or bactericidal actions (Iurlina and Fritz, 2005).…”

The study was aimed at determining the antifungal activities of some honey samples obtained from different geographical locations in Nigeria against some fungal isolates by the method of agar well diffusion. The honey samples were examined for antifungal activity against Aspergillus niger, Aspergillus flavus, Penicillium chrysogenum, Microsporum gypseum, Candida albicans, and Saccharomyces sp. Minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) of the honeys were also determined. Results obtained reveal that the honey samples showed varying levels of inhibitory activity at various concentrations against the fungi tested with zones of inhibition increasing with increasing honey concentration. M. gypseum was the most sensitive of all the fungal isolates studied, while C. albicans was the least sensitive. The MIC and MFC values for the honeys ranged between 12.5 and 50% (v/v). The samples of honey used in the study showed broad spectrum and promising antifungal activity. Nigerian honey can serve as sources of antifungal substances for possible development of antifungal drugs for the treatment of fungal infections.
