Abstract
Microorganisms and helminthes can cause serious diseases in humans as well as in animals. The use of antimicrobial and antihelminthic drugs have created selective pressure and caused resistance to antibiotics used against them, thus it necessitates the use of honey bee’s derived natural products. One such bee derived product is pollen, collected by worker honey bees from the flowering plants and modify it by adding its salivary secretions. The present study embodies use of pollen as antimicrobial and antihelminthic substance. Among microorganisms 4 Gram (+ve) bacteria; (Bacillus subtilis, Staphylococcus epidermidis, Staphylococcus aureus, Streptococcus pneumoniae) and 3 Gram (-ve) bacteria; (Escherichia Coli, Pseudomonas aeruginosa, Salmonella enteric) and 2 yeasts (Candida albicans and Saccharomyces cerevisiae) were used and the methodology used disc diffusion assay and broth dilution method. The antihelminthic effect was observed among amphistomes via bioassay method under in vitro conditions. For observations three types of pollen extracts (ethanolic, methanolic and water extract) were prepared and positive controls used were; Ampicillin for antibacterial, Amphotericin B for antifungal and Albendazole for anti-helminthes. The antimicrobial activities were determined by measuring the zones of inhibition diameters in millimeters after 24 hours of incubation at optimum temperature for each microbe and also by broth dilution method. Results obtained showed that the water extract of pollen was found to be most effective against bacteria used in the present study where; Gram (+ve) bacteria were more susceptible as compared to the Gram (-ve) bacteria. It was also observed that among yeasts; Saccharomyces cerevisiae was more susceptible towards ethanolic extract of pollen while Candida albicans showed more inhibitions towards water extract of pollen. Results also demonstrated that none of the extracts of pollen was found to be effective against Helminthes (amphistomes) used in the present study.
