Antiviral effects of Scaptotrigona postica propolis and their fractions
Introduction Studies about viral infections have a great importance in human and veterinary health, and the number of medications available to treatment these diseases is very reduced, making the search for antiviral molecules an important focus for scientific research. Propolis is a bee material manufactured by the mix of exudate of plants, saliva and bee wax. This product is used to seal the ...
متن کاملHydrolases in the hypopharyngeal glands of workers of Scaptotrigona postica and Apis mellifera (Hymenoptera, Apinae).
Hydrolytic enzymes from hypopharyngeal gland extracts of newly emerged, nurse and foraging workers of two eusocial bees, Scaptotrigona postica, a native Brazilian stingless bee, and the Africanized honey bee (Apis mellifera) in Brazil, were compared. The hypopharyngeal gland is rich in enzymes in both species. Fifteen different enzymes were found in the extracts, with only a few quantitative di...
متن کاملChanges in chemical profile of cephalic salivary glands of Scaptotrigona postica (Hymenoptera, Meliponini) workers are phase-related.
Most advanced eusocial bees recruit their nestmates to food resources. Recently, studies in Meliponini species showed that the cephalic salivary (labial) glands (CSGs) are responsible for the production of scent-trail pheromones. Studies on CSGs have shown changes in glandular cell morphology since the worker emerges from brood combs (newly emerged) till forager phase, which may be correlated t...
متن کاملPhysical-Chemical Parameters of Honey of Stingless Bee (Hymenoptera: Apidae)
The objective of this study was to evaluate the physico-chemical quality of honeys samples of stingless bee (Meliponinae). Physico-chemical analyses were: moisture, color, pH, acidity, electrical conductivity, hydroxymethylfurfural, ashes, diastasic activity, reducing sugars, and sucrose. For the parameters hydroxymethylfurfural, ashes, reducing sugars and sucrose, the samples complied with the...
متن کاملAntibacterial activity of honey from stingless honeybees (Hymenoptera; Apidae; Meliponinae).
The aim of the study was to examine antibacterial activity of the honey of stingless honeybees (Meliponinae). An agar well diffusion assay demonstrated that many honey samples of stingless honeybees inhibited the growth of test strains of Staphylococcus aureus, Enterococcus faecalis, Escherichia coli and Pseudomonas aeruginosa; moreover, they exhibited non-peroxide antibacterial activity agains...
