Acute kidney injury after massive attack of Africanised bees
(BMJ Publishing Group LTD, 2014-03-11)
Acute kidney injury (AKI) is a well-documented complication of massive attack by Africanised bees and can be observed 48-72 h after the accident. We report a case of Africanised bees attack followed by severe and lethal ...
Africanized honey bee (Apis mellifera) venom profiling: Seasonal variation of melittin and phospholipase A(2) levels
(Pergamon-Elsevier B.V. Ltd, 2010-09-01)
Apis mellifera venom is comprised basically of melittin, phospholipase A(2), histamine, hyaluronidase, catecholamine and serotonin. Some of these components have been associated with allergic reactions, amongst several ...
Changes in the morphology and ultrastructure of the Dufour's gland during the life cycle of the bumble bee queen, Bombus terrestris L-(Hymenoptera : Bombini)
(Brill Academic Publishers, 1999-11-01)
The Dufour's gland is found closely associated with the sting apparatus of all female hymenopterans, playing multiple roles among bees. In some species of Bombus the gland may be involved in production of nestmate recognition ...
Identification of a novel melittin isoform from Africanized Apis mellifera venom
(Elsevier B.V., 2010-08-01)
Apis mellifera, the European honey bee, is perhaps the most studied insect in the Apidae family. Its venom is comprised basically of melittin, phospholipase A(2), histamine, hyaluronidase, cathecolamines and serotonin. ...
BIOCHEMICAL VARIABILITY BETWEEN VENOMS FROM DIFFERENT HONEYBEE (APIS-MELLIFERA) RACES
(Elsevier B.V., 1993-10-01)
1. The comparison of molecular exclusion cromatography profiles of venoms from sting apparatuses of Apis mellifera ligustica, Apis mellifera adansonii and Africanized honey-bees in Sephadex G-100 revealed both qualitative ...
A scientific note on the first report of honeybee venom inhibiting Paenibacillus larvae growth
(EDP Sciences, 2014-04)
In the eusocial honeybee, Apis mellifera, worker bees use a stinging apparatus for defense. The sting is upplied with venom by glands localized in the abdomen. Honeybee venom (BV) is composed of at least 18 bioactive ...
Defensive repertoire of the stingless bee Melipona flavolineata Friese (Hymenoptera: Apidae)
(Sociobiology, v. 61, n. 4, p. 541-546, Dec. 2014., 2014)
Enzymatic variability among venoms from different subspecies of Apis mellifera (Hymenoptera: Apidae)
The enzymatic variability was analyzed in venom extracts from bees reared in different colonies of the Africanized, A. m. ligustica and A. m. carnica subspecies. The implications of this variation focused on the biochemistry ...
Acute physiopathological effects of honeybee (Apis mellifera) envenoming by subcutaneous route in a mouse model
Bee stings are a health concern in the Americas, where fatal envenomings due to massive attacks by Africanized honeybees have been documented in the last decades. Most studies on the toxic effects of honeybee venom in ...
