Venoms from the superfamily Formicoidea, Ants. They may contain protein factors and toxins, histamine, enzymes, and alkaloids and are often allergenic or immunogenic.
Insects of the family Formicidae, very common and widespread, probably the most successful of all the insect groups. All ants are social insects, and most colonies contain three castes, queens, males, and workers. Their habits are often very elaborate and a great many studies have been made of ant behavior. Ants produce a number of secretions that function in offense, defense, and communication. (From Borror, et al., An Introduction to the Study of Insects, 4th ed, p676)

Instinctual behavior pattern in which food is obtained by killing and consuming other species.
Venoms from snakes of the subfamily Crotalinae or pit vipers, found mostly in the Americas. They include the rattlesnake, cottonmouth, fer-de-lance, bushmaster, and American copperhead. Their venoms contain nontoxic proteins, cardio-, hemo-, cyto-, and neurotoxins, and many enzymes, especially phospholipases A. Many of the toxins have been characterized.
Venoms obtained from Apis mellifera (honey bee) and related species. They contain various enzymes, polypeptide toxins, and other substances, some of which are allergenic or immunogenic or both. These venoms were formerly used in rheumatism to stimulate the pituitary-adrenal system.
Poisonous animal secretions forming fluid mixtures of many different enzymes, toxins, and other substances. These substances are produced in specialized glands and secreted through specialized delivery systems (nematocysts, spines, fangs, etc.) for disabling prey or predator.

Analysis of ectatomin action on cell membranes. (1/17)

Ectatomin (m = 7928 Da) is a toxic component from the Ectatomma tuberculatum ant venom containing two homologous polypeptide chains (37 and 34 residues) linked to each other by a disulfide bond. In aqueous solution it forms a four alpha-helix bundle. At concentrations of 0.05-0.1 microm, ectatomin forms channels in cellular and artificial bilayer membranes. Immunochemical analysis of the intracellular distribution of ectatomin showed that the toxin gets efficiently inserted into the plasma membrane at a concentration of 5 x 10-7 m and does not penetrate inside the cell. The effect of ectatomin on cardiac L-type calcium current was studied. Calcium currents (ICa) in isolated rat cardiac ventricular myocytes were measured using the whole-cell perforated patch-clamp technique. It was shown that ectatomin at concentrations of 0.01-10 nm inhibited ICa after a latency of few seconds. ICa was decreased twofold by 10 nm ectatomin. However, the most prominent effect of ectatomin was observed after stimulation of ICa by isoproterenol, an agonist of beta-adrenoreceptors, or forskolin, a stimulator of adenylate cyclase. At a concentration of 1 nm, ectatomin abolished the isoproterenol- and forskolin-sensitive components of ICa. The inhibitory effect of ectatomin was partially reversed by subsequent application of 2 microm of forskolin, whereas subsequent isoproterenol application did not produce the same effect.  (+info)

Ponericins, new antibacterial and insecticidal peptides from the venom of the ant Pachycondyla goeldii. (2/17)

The antimicrobial, insecticidal, and hemolytic properties of peptides isolated from the venom of the predatory ant Pachycondyla goeldii, a member of the subfamily Ponerinae, were investigated. Fifteen novel peptides, named ponericins, exhibiting antibacterial and insecticidal properties were purified, and their amino acid sequences were characterized. According to their primary structure similarities, they can be classified into three families: ponericin G, W, and L. Ponericins share high sequence similarities with known peptides: ponericins G with cecropin-like peptides, ponericins W with gaegurins and melittin, and ponericins L with dermaseptins. Ten peptides were synthesized for further analysis. Their antimicrobial activities against Gram-positive and Gram-negative bacteria strains were analyzed together with their insecticidal activities against cricket larvae and their hemolytic activities. Interestingly, within each of the three families, several peptides present differences in their biological activities. The comparison of the structural features of ponericins with those of well-studied peptides suggests that the ponericins may adopt an amphipathic alpha-helical structure in polar environments, such as cell membranes. In the venom, the estimated peptide concentrations appear to be compatible with an antibacterial activity in vivo. This suggests that in the ant colony, the peptides exhibit a defensive role against microbial pathogens arising from prey introduction and/or ingestion.  (+info)

A case of anaphylaxis by ant (Ectomomyrmex spp.) venom and measurements of specific IgE and IgG subclasses. (3/17)

Hypersensitivity to the stings of the Hymenoptera has been described since antiquity. The hypersensitive reactions to insect stings vary from minor skin reactions to severe and sometimes fatal anaphylaxis. Concerns about sting hypersensitivity have been increasing because of many incidents of allergic reactions of patients to the fire ant in the southern area of the United States as well as the harvester ant in some areas. We experienced one unique case with severe allergic reactions by ant of the Ectomomyrmex spp. of the subfamily Ponerinae, which is not a harvester ant. For three years the patient had been suffering from generalized allergic reactions such as anaphylaxis after the ant stings four-five attacks in a year. We determined that her reactions were due to specific IgE mediated type I hypersensitivity by the detection of a high level of specific IgE to the ant venom in her serum. The high level of specific IgG4 to the ant venom was also noted in her serum, however, the role of ant venom IgG4 was not clearly determined.  (+info)

Poneratoxin, a neurotoxin from ant venom. Structure and expression in insect cells and construction of a bio-insecticide. (4/17)

Poneratoxin is a small neuropeptide found in the venom of the ant Paraponera clavata. It is stored in the venom reservoir as an inactive 25-residue peptide. Here we describe both chemically synthesized poneratoxin and poneratoxin obtained by expression in insect cells. When expressed in insect cells, poneratoxin was observed attached to cell membranes. Both synthetic and recombinant ponerotoxins were soluble below pH 4.5. The structure of synthetic poneratoxin was characterized by circular dichroism and solved by nuclear magnetic resonance. In an environment imitating a lipid bilayer, at pH within the range of insect hemolymph, synthetic poneratoxin has a V shape, with two alpha-helices connected by a beta-turn. Insect larvae were paralyzed by injection of either of the purified toxins, with the recombinant one acting faster. The recombinant toxin-producing baculovirus reduced the average survival time of the insect host by 25 h compared with unmodified virus. Mass spectrometry analysis showed that the recombinant toxin has an N-terminal 21-residue extension, possibly improving its stability and/or stabilizing the membrane-bound state. The potential use of poneratoxin for the construction of biological insecticide is discussed.  (+info)

Description of an injury in a human caused by a false tocandira (Dinoponera gigantea, Perty, 1833) with a revision on folkloric, pharmacological and clinical aspects of the giant ants of the genera Paraponera and Dinoponera (sub-family Ponerinae). (5/17)

The authors observed an injury caused by the sting of a false tocandira ant in the hand of an amateur fisherman and they describe the clinical findings and the evolution of the envenoming, which presented an acute and violent pain, cold sweating, nausea, a vomiting episode, malaise, tachycardia and left axillary's lymphadenopathy. About three hours after the accident, still feeling intense pain in the place of the sting, he presented an episode of great amount of blood in the feces with no history of digestive, hematological or vascular problems. The intense pain decreased after eight hours, but the place stayed moderately painful for about 24 hours. In that moment, he presented small grade of local edema and erythema. The authors still present the folkloric, pharmacological and clinical aspects related to the tocandiras stings, a very interesting family of ants, which presents the largest and more venomous ants of the world.  (+info)

Insect venom hypersensitivity: experience in a clinical immunology/allergy service in Singapore. (6/17)

INTRODUCTION: To study the profile of patients with allergy to the venom of insect stings. METHODS: 31 consecutive cases referred to our clinical immunology/allergy outpatient service from June 1, 1998 to June 30, 2002 were reviewed. RESULTS: These patients comprised 3.5 percent of 889 cases referred during the study period. Their mean age was 28.8 +/- 10.5 (range 19-57) years and the majority were males (90.3 percent). Of these, 20 (64.5 percent) were Chinese, four (12.9 percent) were Malays and seven (22.6 percent) were of other races. 19 patients (61.3 percent) were men from the uniformed services including 12 (63.2 percent) full-time National Servicemen. 71 percent (22 patients) were stung for the first time. Urticaria (22 cases, 71.0 percent), dyspnoea (13, 41.9 percent), angioedema (12, 38.7 percent) and syncope (ten, 32.3 percent) were the most common manifestations of insect allergy. Anaphylaxis occurred in 22 (71.0 percent) cases, constituting 30.1 percent of all cases of anaphylaxis referred to our service during the study period. Although the causative insect was identified as honeybee (12, 38.7 percent), ant (four, 12.9 percent), wasp (three, 9.7 percent), and fire ant (two, 6.5 percent) by the majority of patients, ten (32.2 percent) patients were unable to identify the causative insect. The two patients stung by fire ants were Americans working in Singapore who had been stung while in the United States. Among those with anaphylaxis, honeybee, wasp and fire ant venom, for which specific immunotherapy is available, were identified as the cause in 40.9 percent, 4.5 percent, and 4.5 percent, respectively. CONCLUSION: Insect venom hypersensitivity made up 3.5 percent of allergy/immunology referrals and 32.8 percent of cases of anaphylaxis referred to our institution. The majority were military servicemen who developed allergic reactions during the course of duty. The inability to identify the causative insect in 50 percent with sting anaphylaxis limits the role of specific immunotherapy in our patients.  (+info)

Anaphylaxis caused by imported red fire ant stings in Malaga, Spain. (7/17)

A 27-year-old woman suffered from anaphylaxis after being stung by Solenopsis invicta ants while she was handling wood from South America. The patient reported no previous adverse reactions to stings by other hymenopteran species. Intradermal skin tests with hymenoptera venom (Vespula vulgaris, Polistes species, Apis melifera) were negative. Serum specific immunoglobulin (Ig) E yielded positive results for S invicta (5.28 kU/L) and negative results for A melifera, Ves v 5 and Pol a 5. Immunodetection assays showed the presence of serum IgE against the Sol i 2 allergen. The patient had probably been stung previously although inadvertently by red fire ants while she handled infested wood from South America, and precautionary measures are thus advisable when this material is to be handled. To our knowledge this is the first case of anaphylaxis from red fire ant stings reported in Europe.  (+info)

My journey to the ants. (8/17)

In this paper, I review the strange, unplanned and unexpected journey I have had with Solenopsis invicta, the imported fire ant. Through serendipity, good fortune and repeated invenomation, I have come to count as collaborators a number of entomologists, toxicologists, allergists and immunologists who have guided me on this journey to the ants. We now understand the mechanisms for the cutaneous reactions experienced by 50% of the exposed population stung per year, as well as the immunologic and toxicologic properties of the ants unique venom. Allergen immunotherapy to fire ant extracts has been demonstrated to protect patients from repeat anaphylaxis. Methods have been developed to prevent and treat massive sting attacks on frail elders, including those in residential and medical facilities. The potential beneficial effects of venom components are under investigation. And yes, the journey and the stings continue.  (+info)

Ant venoms are toxic secretions produced by various species of ants as a defense mechanism against predators and to incapacitate their prey. The composition of ant venoms varies among different species, but they typically contain a mixture of alkaloids, peptides, and proteins that can cause a range of symptoms in humans, from mild irritation and pain to severe allergic reactions.

The venom of some ant species, such as the fire ants (Solenopsis spp.), contains alkaloids that can cause painful pustules and itching, while the venom of other species, like the bulldog ants (Myrmecia spp.), contains proteins that can induce severe allergic reactions and even anaphylactic shock in sensitive individuals.

Understanding the composition and effects of ant venoms is important for developing effective treatments for ant stings and for studying their potential therapeutic applications, such as using ant venom components in pain management or as leads for new drug development.

I believe you may have accidentally omitted the word "in" from your search. Based on that, I'm assuming you are looking for a medical definition related to the term "ants." However, ants are not typically associated with medical terminology. If you meant to ask about a specific condition or concept, please provide more context so I can give a more accurate response.

If you are indeed asking about ants in the insect sense, they belong to the family Formicidae and order Hymenoptera. Some species of ants may pose public health concerns due to their ability to contaminate food sources or cause structural damage. However, ants do not have a direct medical definition associated with human health.

An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.

In the context of mental health and psychology, "predatory behavior" is not a term that is commonly used as a medical diagnosis or condition. However, it generally refers to aggressive or exploitative behavior towards others with the intention of taking advantage of them for personal gain or pleasure. This could include various types of harmful behaviors such as sexual harassment, assault, stalking, bullying, or financial exploitation.

In some cases, predatory behavior may be associated with certain mental health conditions, such as antisocial personality disorder or psychopathy, which are characterized by a disregard for the rights and feelings of others. However, it's important to note that not all individuals who engage in predatory behavior have a mental health condition, and many people who do may not necessarily exhibit these behaviors.

If you or someone else is experiencing harm or exploitation, it's important to seek help from a trusted authority figure, such as a healthcare provider, law enforcement officer, or social worker.

Crotalid venoms are the toxic secretions produced by the members of the Crotalinae subfamily, also known as pit vipers. This group includes rattlesnakes, cottonmouths (or water moccasins), and copperheads, which are native to the Americas, as well as Old World vipers found in Asia and Europe, such as gaboon vipers and saw-scaled vipers.

Crotalid venoms are complex mixtures of various bioactive molecules, including enzymes, proteins, peptides, and other low molecular weight components. They typically contain a variety of pharmacologically active components, such as hemotoxic and neurotoxic agents, which can cause extensive local tissue damage, coagulopathy, cardiovascular dysfunction, and neuromuscular disorders in the victim.

The composition of crotalid venoms can vary significantly between different species and even among individual specimens within the same species. This variability is influenced by factors such as geographic location, age, sex, diet, and environmental conditions. As a result, the clinical manifestations of crotalid envenomation can be highly variable, ranging from mild local reactions to severe systemic effects that may require intensive medical treatment and supportive care.

Crotalid venoms have been the subject of extensive research in recent years due to their potential therapeutic applications. For example, certain components of crotalid venoms have shown promise as drugs for treating various medical conditions, such as cardiovascular diseases, pain, and inflammation. However, further studies are needed to fully understand the mechanisms of action of these venom components and to develop safe and effective therapies based on them.

Bee venom is a poisonous substance that a honeybee (Apis mellifera) injects into the skin of a person or animal when it stings. It's produced in the venom gland and stored in the venom sac of the bee. Bee venom is a complex mixture of proteins, peptides, and other compounds. The main active components of bee venom include melittin, apamin, and phospholipase A2.

Melittin is a toxic peptide that causes pain, redness, and swelling at the site of the sting. It also has hemolytic (red blood cell-destroying) properties. Apamin is a neurotoxin that can affect the nervous system and cause neurological symptoms in severe cases. Phospholipase A2 is an enzyme that can damage cell membranes and contribute to the inflammatory response.

Bee venom has been used in traditional medicine for centuries, particularly in China and other parts of Asia. It's believed to have anti-inflammatory, analgesic (pain-relieving), and immunomodulatory effects. Some studies suggest that bee venom may have therapeutic potential for a variety of medical conditions, including rheumatoid arthritis, multiple sclerosis, and chronic pain. However, more research is needed to confirm these findings and to determine the safety and efficacy of bee venom therapy.

It's important to note that bee stings can cause severe allergic reactions (anaphylaxis) in some people, which can be life-threatening. If you experience symptoms such as difficulty breathing, rapid heartbeat, or hives after being stung by a bee, seek medical attention immediately.

Venom is a complex mixture of toxic compounds produced by certain animals, such as snakes, spiders, scorpions, and marine creatures like cone snails and stonefish. These toxic substances are specifically designed to cause damage to the tissues or interfere with the normal physiological processes of other organisms, which can lead to harmful or even lethal effects.

Venoms typically contain a variety of components, including enzymes, peptides, proteins, and small molecules, each with specific functions that contribute to the overall toxicity of the mixture. Some of these components may cause localized damage, such as tissue necrosis or inflammation, while others can have systemic effects, impacting various organs and bodily functions.

The study of venoms, known as toxinology, has important implications for understanding the evolution of animal behavior, developing new therapeutics, and advancing medical treatments for envenomation (the process of being poisoned by venom). Additionally, venoms have been used in traditional medicine for centuries, and ongoing research continues to uncover novel compounds with potential applications in modern pharmacology.
