Fractionation of bulldog ant venom
Toxicon, 1974Abstract The venom of an Australian Bulldog Ant, Myrmecia pyriformis, has been fractionated by means of low voltage starch gel electrophoresis and gel filtration on Sephadex G50 and G75 columns. The aims of the study were (a) to establish whether the biological activities which had previously been described resided in separate venom components, and ...

Kinins in ant venoms—A comparison with venoms of related hymenoptera
Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 19891. Venom preparations have been made of six ant, one pompilid wasp, two mutillid wasp, and four social wasp species. 2. The venoms were analysed pharmacologically in order to detect kinin-like activity. 3. Due to the small amounts of venoms available only a cascade of smooth muscle preparation could be used. 4.

51 Fire ant venom hypersensitivity
Journal of Allergy and Clinical Immunology, 1983Abstract Levels of IgE antibody to fire ant whole body extract (FA-WBE) and fire ant venom (FAV) were evaluated in 60 patients with clinical histories of fire ant sting hypersensitivity and 11 frequently stung individuals without significant clinical reactivity to fire ant. An overlap of levels of IgE antibody to FA-WBE and FAV was seen between groups

Current Opinion in Allergy & Clinical Immunology, 2010
The review summarizes knowledge about ants that are known to sting humans and their venoms.Fire ants and Chinese needle ants are showing additional spread of range. Fire ants are now important in much of Asia. Venom allergens have been characterized and studied for fire ants and jack jumper ants.

Venom chemistry of ants in the genusMonomorium
Journal of Chemical Ecology, 1982A comparative analysis of the venomous alkaloids produced by ant species in the subgenusMonomorium of the genusMonomorium has been undertaken. All species produce mixtures of unsymmetricaltrans-2,5-dialkylpyrrolidines, but the proportions of the constituents may vary considerably between species.

Hypersensitivity to Fire Ant Venom
Annals of Allergy, Asthma & Immunology, 1996Reading this article will reinforce the reader's knowledge of the taxonomy, origin, and distribution of fire ants and will increase his ability to diagnose and manage reactions caused by the two imported species, Solenopsis invicta and richteri. This review will also enhance the reader's knowledge of the available diagnostic methods and therapeutic ...

Prevention of anaphylaxis with ant venom immunotherapy
Current Opinion in Allergy and Clinical Immunology, 2003Worldwide, eight genera of ants have been associated with sting allergy. Until recently only whole ant body extracts have been used for immunotherapy. The purpose of this review is to examine recent advances in the understanding of ant venom allergy and treatment using venom immunotherapy.Public health problems due to severe ant sting anaphylaxis are ...

Organismal Biology![Figure][1] The giant red bull ant has complex multifunctional venom. PHOTO: KAAREL OLESK/GETTY IMAGES Ant venoms are primarily made up of poorly characterized polypeptides. Robinson et al. combined transcriptomics and mass spectrometry–based proteomics to determine the mechanism of action of giant red bull ant venoms.

Histamine release by fire ant (Solenopsis) venom
Toxicon, 1978Abstract Venoms from the fire ants Solenopsis invicta and S. geminata were free of detectable histamine but caused histamine release from rat peritoneal mast cells in vitro. On a per ant basis, venom from S. invicta ( ed 50 = 0·12 venom reservoirs/ml ) was four times as potent as venom from S.
