Picaduras venenosas en el mundo tropical: accidente por mordeduras y picaduras de un enjambre de abejorros en una selva lluviosa venezolana

[摘要] Se describen 2 casos de envenenamiento producidos por el ataque inusual de colonias de insectos de la familia Bombidae, conocidos de forma popular como abejorros. Este tipo de envenenamiento puede llegar a ser de toxicidad severa y se analiza a la luz de los últimos hallazgos, caracterizados por síntomas hemorrágicos tales como hematemesis y melena.Descriptores DeCS: MORDEDURAS Y PICADURAS DE INSECTOS; VENENOS DE ABEJA/envenenamiento; ABEJAS; HEMATEMESIS/etiología; MELENA/etiología; MEDICINA TROPICAL; VENEZUELA.The published literature in Venezuela on wasp-sting or bumblebees-bites (or sting) allows no mean of the determination of the incidence of this envenomation.The literature about behavior of these insects reported it as animals of life in society, building its nets with vegetable litter in the ground, flying accompanied when they are going to mate.1 Since scientific point of view they belong to Bombus Latreille, 1802 genus. This genus is distributed from the Nothern hemisphere with a deep penetration in South America, invading different habitats such as humid and hot climes in tropical zones to cold clines in high mountains. Bombus morio has been reported in Brasil, Ecuador and Bolivia (Moure and Sakagami), but as far as we known it has not been reported for Venezuela. Potentially, those insects are very hazardous, being able to provoke serious accidents and death with an alone stung.2,3 In the national or international literature4 has been reported swarm bumblebees massive attacks anywhere, such as it is seen in the africanized bees or common bees (Apis melifera).The accidents produced by bees are generally of allergic or anaphylactic nature.5 As far we as known, it has not been described other toxic activities in bumblebee venom.In this paper we are reporting a swarm of bumblebees (Bombus morio) bites and stings accident occurred to a researchers team working in a Venezuelan rainforest, whom presented a non-described bumblebees venon activity clinical picture, characterized by hematemesis, melena as well as inflammatory and bites dermic lesions.ME
