The antimicrobial activity and microbiological safety of stingless bee honeys from Costa Rica
Stingless bee honeys from Costa Rica possess etnopharmacological value mainly as a wound dressing. The microbiological study by APHA methods reported that 83 % of the honeys analysed had microbial counts that comply with European Pharmacopoeia's acceptance criteria for microbiological quality of non-sterile substances for pharmaceutical use. All samples reported the absence of Clostridium botulinum spores by PCR. Over 90 % of Tetragonisca angustula and Melipona beecheii honeys inhibited Pseudomonas aeruginosa and Staphylococcus aureus at minimum inhibitory concentrations lower than Medihoney™. Under the conditions tested, Medihoney™ was not active against Candida albicans, whereas 53% of T. angustula honeys rendered inhibition. The melissopalynological analyses reported a homogeneous (monofloral) botanical composition for the Meliponini honeys, which emphasizes the contribution of nectar constituents to the antimicrobial activity and provides foundation to the standardization of a desired inhibitory effect. The traditional use of Costa Rican stingless bee honey as a dressing for burns and wounds reveals the application of a proficient antiseptic agent with low health associated risks.
