Costa rican pot-honey: Its medicinal use and antibacterial effect
(Springer, 2012-11-19) Zamora Fallas, Luis Gabriel; Arias, María Laura; Aguilar Monge, Ingrid; Umaña Rojas, Eduardo
There are very few records on the use of pot-honey by indigenous people of Costa Rica. Our evaluation concerns antimicrobial activity of honey samples from Tetragonisca angustula, Melipona beecheii and Apis mellifera, performed to determine whether traditional appreciation of stingless bee honey from Costa Rica, over that of A. mellifera honey, is justified by this criterion. The stingless bee honeys were more active than that of A. mellifera against Staphylococcus aureus and Pseudomonas aeruginosa―currently the major causes of burn and wound infections. The results presented herein are among the first steps towards further study of antimicrobial components in Costa Rican stingless bee honey.
Microscopic Image Processing for the Analysis of Nosema Disease
(IGI Global., 2019) Calderón, Rafael; Dghim, Soumaya; Travieso-González, Carlos M.; Gouider, Mohamed Salah; Ramírez-Bogantes, Melvin; Prendas Rojas, Juan Pablo; FIGUEROA-MATA, Geovanni
In this chapter, the authors tried to develop a tool to automatize and facilitate the detection of Nosema disease. This work develops new technologies in order to solve one of the bottlenecks found on the analysis bee population. The images contain various objects; moreover, this work will be structured on three main steps. The first step is focused on the detection and study of the objects of interest, which are Nosema cells. The second step is to study others’ objects in the images: extract characteristics. The last step is to compare the other objects with Nosema. The authors can recognize their object of interest, determining where the edges of an object are, counting similar objects. Finally, the authors have images that contain only their objects of interest. The selection of an appropriate set of features is a fundamental challenge in pattern recognition problems, so the method makes use of segmentation techniques and computer vision. The authors believe that the attainment of this work will facilitate the diary work in many laboratories and provide measures that are more precise for biologists.
Stingless bees of Costa Rica
(Springer, 2012-11-19) Aguilar Monge, Ingrid; Herrera González, Eduardo; Zamora Fallas, Luis Gabriel
The keeping of stingless bees (Apidae, Meliponini) or meliponiculture is carried out in a rustic and traditional way in Costa Rica. This is an activity present in several regions of the country, especially among the inhabitants of rural areas, mostly on the Pacific coast rather than the Atlantic region. According to our most recent data, the number of stingless bee keepers has progressively increased. However, compared to previous studies, the number of colonies per person has declined. This partially is due to the practice, in many cases, of keeping bees as a hobby more than as a source of improvement in family income. A total of 20 different domesticated species have been reported and the most commonly kept species is T. angustula.
