Helicobacter pylori: A spiral bacterium active as a human gastric pathogen. It is a gram-negative, urease-positive, curved or slightly spiral organism initially isolated in 1982 from patients with lesions of gastritis or peptic ulcers in Western Australia. Helicobacter pylori was originally classified in the genus CAMPYLOBACTER, but RNA sequencing, cellular fatty acid profiles, growth patterns, and other taxonomic characteristics indicate that the micro-organism should be included in the genus HELICOBACTER. It has been officially transferred to Helicobacter gen. nov. (see Int J Syst Bacteriol 1989 Oct;39(4):297-405).Stomach Ulcer: Ulceration of the GASTRIC MUCOSA due to contact with GASTRIC JUICE. It is often associated with HELICOBACTER PYLORI infection or consumption of nonsteroidal anti-inflammatory drugs (NSAIDS).Gastric Mucosa: Lining of the STOMACH, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. The surface cells produce MUCUS that protects the stomach from attack by digestive acid and enzymes. When the epithelium invaginates into the LAMINA PROPRIA at various region of the stomach (CARDIA; GASTRIC FUNDUS; and PYLORUS), different tubular gastric glands are formed. These glands consist of cells that secrete mucus, enzymes, HYDROCHLORIC ACID, or hormones.Helicobacter Infections: Infections with organisms of the genus HELICOBACTER, particularly, in humans, HELICOBACTER PYLORI. The clinical manifestations are focused in the stomach, usually the gastric mucosa and antrum, and the upper duodenum. This infection plays a major role in the pathogenesis of type B gastritis and peptic ulcer disease.PeruAnti-Bacterial Agents: Substances that reduce the growth or reproduction of BACTERIA.Gastritis: Inflammation of the GASTRIC MUCOSA, a lesion observed in a number of unrelated disorders.Stomach Neoplasms: Tumors or cancer of the STOMACH.Microbial Sensitivity Tests: Any tests that demonstrate the relative efficacy of different chemotherapeutic agents against specific microorganisms (i.e., bacteria, fungi, viruses).Amoxicillin: A broad-spectrum semisynthetic antibiotic similar to AMPICILLIN except that its resistance to gastric acid permits higher serum levels with oral administration.Ant Venoms: Venoms from the superfamily Formicoidea, Ants. They may contain protein factors and toxins, histamine, enzymes, and alkaloids and are often allergenic or immunogenic.Ants: 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.

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)

The toxicology of red imported fire ant venom has been extensively studied. The venom is important to the red imported fire ant, enabling it to capture its prey and to defend itself. Some 14 million people are bitten annually in the United States, suffering reactions including sensitivity and anaphylactic shock. The venom contains some 46 proteins of which four are allergens. Venom plays an important role in a red imported fire ant colony, being used to capture prey items, for defence, and antimicrobial action. On average, however, a worker produces very little venom (less than 1 µg/kg). Newborn workers contain little to no venom within their reservoirs, but workers that are only one-day old can produce 1.17 µg/kg. However, workers that are 15 days old only produce 0.3 µg/kg. Workers deliver 0.66 nl of venom when they sting, which amounts to 3.1% of their supply. Older workers deliver less venom when they sting, but middle-aged workers and nest-defenders deliver much higher quantities. Like ...

The phorid fly, Pseudacteon tricuspis Borgmeier, is an introduced parasitoid of imported fire ants, Solenopsis spp., in the USA. Although the assumption that phorid flies use fire ant alarm pheromones for host location is probably true, we demonstrated in a previous study the possible involvement of other ant semiochemicals in the response of P. tricuspis to fire ants. This study was conducted to determine the glandular sources and identity of the semiochemicals mediating this interaction. First, we tested the electroantennogram response of P. tricuspis to extracts of key body parts and glands of workers of the red imported fire ant, S. invicta Buren. The results confirm that the poison (venom) gland/sac is the key source of compounds which elicited strong antennal activity in P. tricuspis. Follow-up studies were conducted by using a combination of bioassay-guided fractionation and behavioral bioassays to test the hypothesis that attraction of this parasitoid to fire ants is mediated by venom alkaloids.
Solenopsin is an alkaloid with the molecular formula C17H35N found in the venom of fire ants (Solenopsis). It is considered the primary toxin in the venom and may be the component responsible for the cardiorespiratory failure in people who experience excessive fire ant stings. Chemically, solenopsin contains a piperidine ring substituted with a methyl group and a long hydrophobic chain. Fire ant venom contains other chemically related piperidines which make purification of solenopsin from ants difficult. Therefore, solenopsin and related compounds have been the target of organic synthesis from which pure compounds can be produced for individual study. Originally synthesized in 1998, several groups have designed novel and creative methods of synthesizing enantiopure solenopsin and other alkaloidal components of ant venom. The total synthesis of solenopsin has been described by several methods. The method proposed by Bowen et al.(Figure 1) starts with alkylation of 4-chloropyridine with a Grignard ...

Insect venoms are complicated. Really complicated. You could be forgiven for thinking that it must be a relatively simple company of chemicals that makes up the painful sensation of a bee or wasp sting, but in fact a hugely complex mixture of all sorts of compounds - proteins, peptides, enzymes, and other smaller molecules - go into a small amount of venom. The range of compounds is far too vast to detail every single one - but we can examine some of the major constituents in bee, wasp, hornet and ant venom.. Well start with the venom about which we know the most - that of bees. Unlike many other insect venoms, we have a relatively good idea of the percentage breakdown of the venom of your average bee. When the bee stings, the venom is mixed with water, so the actual composition of the substance it injects into you is around 88% water and 12% venom. From this point onward, well consider the percentages of compounds purely in the venom itself.. The main toxic component of bee venom, also ...
Natural antioxidants play central roles in enhancing the immune system via mechanisms that depend on oxidative stress; in turn, oxidative stress appears to play significant roles in many human diseases. In this context, we previously demonstrated that thymoquinone benefits the treatment of multiple myeloma and alleviates diabetic complications by restoring the T-cell immune response in diabetic offspring [34-36]. Interestingly, we showed that natural antioxidants isolated from snake and ant venoms were able to enhance normal lymphocyte function and exert antitumor effects on breast cancer cells [37, 38]. Propolis is a natural antioxidant product found in plant materials and is processed by worker bees. Natural antioxidants play various biological roles in the treatment of diabetic complications, including impaired wound healing [39-41] and T-cell immune responses, in offspring born to diabetic mothers, as well as the treatment of other diseases, including cancer [42-44]. Cytokines are essential ...

N2 - Background The ant species Pachycondyla chinensis, which has spread from Far Eastern Asia to New Zealand and North America, induces anaphylactic reactions in human with its sting. However, the major allergens of P. chinensis have not yet been characterized. Methods We selected seven patients with histories of anaphylaxis induced by P. chinensis. Two-dimensional electrophoresis (2-DE) was used to identify the major allergens. We subsequently performed Western blots for P. chinensis-specific IgEs, N-terminal amino acid sequencing, ESI-MS/MS, and RT-PCR using primers based on the N-terminal sequence. Results Six of the anaphylactic subjects had an IgE specific to a 23 kDa allergen of P. chinensis. Two ...

This chapter highlights the severity of problems that the red fire ant caused and the opinions that clustered around the belief that the ant was a pest to be dealt with. This chapter also explains that the insecticides used to kill it were either a threat to other forms of life or were used with little regard for consequences. The ant changed its behavior in some areas where it had long been established, its density also declined along with its tendency to attack crops and vertebrates. During the same time, the insecticides were following their own natural laws, killing ants and songbirds. All these events were observed by people who had different standpoints who therefore interpreted these changes differently. The opinions of both the conservationists and environmentalists about the insect, the insecticides, and the eradication program surfaced from an interaction between the natural world and the ideas of those who represented different interests in American society. ...

Allergic reactions to insect stings result from an overreaction of a childs immune system to the venom injected by the insect. After the first sting, the childs body produces an allergic substance called immunoglobulin E (IgE) antibody, which reacts with the insect venom. If the child is stung again by the same type of insect or by one from a similar species, the insect venom will interact with the IgE antibody produced in response to the previous sting. This in turn causes the release of histamine and several other chemicals that cause allergic symptoms. The sting of an insect may only cause a local response, where pain, redness, itching, and swelling are confined to the site of the sting. This type of reaction is considered normal. The normal reaction to fire ant stings is different. Clear blisters usually form within several hours then become cloudy within 24 hours. (The reaction usually presents in a ring or cluster, since a fire ant pivots and repeatedly stings. Also, fire ants travel in ...

Reading selectmen Brooks facebook page, I noticed a picture of a red fire hydrant with the caption pay it forward, help the fire fighters by cleaning the hydrants near you of snow. I could be wrong but I think the residents of Templeton (taxpayers) already pay taxes for town services. These include a highway department, and since this department just bought a new loader which equates to three loaders being parked at the highway barn these days. It is my opinion that there is enough time for the highway department, cemetery & parks or the water department to do this job. Taxpayers pay taxes for services and I believe if selectmen Brooks took the time to look, she would find who has the responsibility to do this job. My opinion is people should not be asked to do a job they already pay to have done through their taxes! This pay it forward picture may make for a warm fuzzy feeling and a good rah rah cheerleading scenario, it is in the end, asking people to pay twice for a service and it is simply ...

Known History: Born in a remote location just outside of Vacuo, life was already difficult with the lack of outside support. When a group of Griffins swarmed the town when Charlene was only eight, however, things couldnt have gotten worse... She was lucky to have survived, as it was when she found the sense to run that she discovered her Semblance... which didnt, at the time, do anything more than stall just long enough for her to get past the Griffins that tried to attack. What made matters worse was when the town suddenly burst into an enormous ball of red fire for reasons that even she couldnt tell you. It IS theorized, however, that the Dust merchant visiting at the time had found the sense to gather up enough Fire Dust to wipe out every non-flammable thing in the town, not long after Charlene had gotten to cover just outside the towns now shattered borders. Knowing shed have to survive on her own, since then, shed tried every possible way to get by. Using her Semblance to perform, ...

The core utilizes a dual-density design along with a moderate differential to produce a responsive backend reaction. Bottom line is that the Red Fire Pearl Octane Carbon creates easy length down the lane with continuous backend motion that powers through the pin deck.. ...
Blue Velvet opens on a Lumberton so idyllic it seems parodic: bright flowers along a white picket fence, a radio jingle, a shiny red fire truck from which a smiling fireman waves to us, the filmgoer. An indeterminate period. Some cars and clothes are 1980s, yet fashion and music, malt shop and nightclub mike, also draw from the 1940s through 1960s. (Lynch detests 1970s design, telling Powers: The cars were pitiful. I mean pitiful. It made you ashamed.) J.G. Ballard describes the visual style as a clash between Norman Rockwells Americana and Edward Hoppers noir..

European fire ants are a nuisance pest for people and a potential threat to the environment. They aggressively defend their territory and readily sting humans, pets and livestock that have the misfortune to move slowly or rest within the ants large foraging areas.. The severity of reaction to the European fire ant sting varies from one individual to another, and with the location of the sting. Usually a sting results in an inflamed red area from one to four inches in diameter, sometimes with a raised white area in the center. The sting causes an initial burning sensation and the affected area can remain sore for just a few hours, or a day or more.. Where this insect has established nests, homeowners have reported that they are unable to use their yards and gardens because of repeated stings by the ants.. If European fire ants move into new places, they may threaten native species of ants. In Europe, it is believed that competition with other native ants prevents the European fire ant from ...

Extinguish Plus Fire Ant Bait contains both an Insect Growth Regulator and an insecticide to kill the entire colony, queen and all. Broadcast Extinquish Plus Fire Ant on yard or treat mounds individually.
If more than 5 mounds are present, then treatment should be broadcasted over the entire area. A fire ant bait or contact insecticide may be used. Fire ant baits are made up of defatted corn grit covered with insecticide and soybean oil. Before broadcasting the fire ant bait, foraging activity should be evaluated. In order to test for foraging activity, place a potato chip or hot dog next to the mound. If fire ants find the chip or hot dog within fifteen minutes, then it is an appropriate time to broadcast the fire ant bait. Fire ants will typically actively forage when the soil surface temperature is between 70 and 90° F. The delivery process of fire ant baits into the colony is so effective, that the amount of insecticide applied in an area is significantly reduced. Fire ant baits should never be watered into the soil and they should not be used if they smell rancid. Contact insecticides can also be broadcasted over the entire area and these need to be watered into the soil. One contact ...

Formic acid (systematically called methanoic acid) is the simplest carboxylic acid. Its formula is HCOOH or HCO2H. It is an important intermediate in chemical synthesis and occurs naturally, most notably in the venom of bee and ant stings. In fact, its name comes from the Latin word for ant, formica, referring to its early isolation by the distillation of ant bodies. An ester or salt derived from formic acid is referred to as formate. ...

Greenberg L.; Fletcher D.J.C.; Vinson S.B., 1985: Differences in worker size and mound distribution in monogynous and polygynous colonies of the fire ant solenopsis invicta
Fire ants may be tiny - just 1/4 inch or less in length - but if youve ever been stung by them, you know that they pack quite a wallop. They may be similar to other red or black ants in appearance, but fire ants react angrily when their nest is disturbed. The ant first bites the skin, then inserts its stinger and injects a venom. The ant can sting several times in the same area, and many ants may attack at the same time. Reaction to the stings depends on your degree of allergy, but pustules up to 1/8 inch in diameter develop on the skin within 24 hours and can be very painful and sometimes require medical attention.. In addition to being a potential health hazard to humans and animals, fire ants often create a real problem for homeowners by building their mounds in lawns and gardens. The mounds can be a foot high and can seriously damage mowers and tillers.. Fire ants have spread across much of the southern United States and continue to advance into new areas. If you have fire ants in your ...
Since both pest and non-pest ant species so commonly exist in the same orchard, monitoring plays an important role in efficient ant management. In agricultural cropping environments, coarse morphological differences, such as number of nodes on the petiole, presence of a sting, and color and size provide enough information to properly identify pest and non-pest ants. Learning about foraging activity and behavior, nest location and manner in which ants deposit tailings around the entrance hole is also helpful when distinguishing different ant species.. The UC IPM link above provides descriptions and a key for identification. In addition to what is on the website, other characteristics can help in identification. For instance, during hot daytime temperatures the foraging activity of southern fire ant diminishes considerably, while that of the native gray remains high. Also, during foraging, the native gray moves in a more herky-jerkey fashion than the southern fire ant. Both the southern fire ant ...

Chronic inflammation is believed to promote cancer through cellular and genomic damage. Inflammation creates a microenvironment within the tissue that enhances cell proliferation. In 2016, American Cancer Society estimates that 1,685,210 new cancer cases are expected to be diagnosed in the United States. Cyclooxygenase (COX) is an enzyme found to play an essential role in inflammation and converts arachidonic acid to prostaglandin-like molecules. The three isomers of COX are COX-1, COX-2, and COX-3. COX-2 has been found to be up-regulated in inflammation and some cancers, such as breast cancer and prostate cancer. Tetrahydropyridines (THPs) developed by our research group were effective in inhibiting inflammation, COX, and the growth of some breast cancer cells. Previous research has shown that pharmacological activities of the THP derivatives depend greatly on the nature and position of the substituents on the THP ring structure.

ants have a skinny little waist through which their digestive tract must pass. Solid food would lodge in the bottleneck and kill the ant, so the ants cant eat solids. They can only drink.. Yet, in forgoing solid food ants miss out on all sorts of protein available in the environment. Ants must either give up protein or figure out how to convert solids into drinkable juice. Thats where the larvae come in.. Larvae are made to eat and can handle all manner of food. They consume the solids that the worker ants have brought back to the nest and, after a little digestion, pass the protein back as a liquid. Most ant species have a simple, elegant way to do this: they regurgitate for the adults when prompted. But this direct food-passing behavior only appears in the more recent ant lineages. The ancient subfamily Amblyoponinae- including Adetomyrma- diverged from the rest of the ants over 100 million years ago and couldnt inherit this sensible way of doing things.. Natural selection is a blind ...

The ultrastructure of the fat body cells (trophocytes) of the last larval instar of Pachycondyla (= Neoponera) villosa is presented. The cytoplasm is restricted to the cell periphery and to the smaller strips among the vacuoles, protein granules, lipid droplets, and around the nucleus. Cytochemically, the presence of basic amino acids in the protein granules and in the nuclei was observed by using the ethanolic phosphotungstic acid technique (EPTA). The lipid droplets stained for unsaturated lipids. This result was further confirmed by gas chromatography and mass spectrometry, where the unsaturated fatty acids were identified as oleic and linoleic acids together with saturated fatty acids such as palmitic and stearic acid. Carbohydrates (glycogen) were also detected in the fat body. The glycogen is present as β particles distributed among the lipid droplets and sometimes attached to them.

Mandibles are also crucial to the hunting success of predatory ants. Mandibles can be wielded as formidable weapons in their own right, or as tools with which to grasp prey until a paralyzing sting can be delivered (a common strategy in the Ponerinae, most of which are solitary predators). Mass foraging predators (e.g. army ants, described below) use their mandibles to pin down prey from all sides while their nestmates dispatch it. A number of highly modified mandibles have evolved in response to the requirements of catching certain prey, especially those that are otherwise difficult to catch (e.g. collembolans). See the section on specialized predators below for several examples of such modifications. Despite a common misconception, most ants lack painful bites (being too small to have any effect on human skin). Usually ant "bites" are actually the venomous stings of ants in certain subfamilies (most commonly the Myrmicinae, but also members of the Ponerinae, Myrmeciinae, Pseudomyrmecinae, and ...
The inchman (Myrmecia forficate) is a species of bull ant that can be found in Australia, in a range that includes Tasmania and possibly southeastern areas of Australia. This species is gregarious, living in colonies like most other ant species, but it forages for food alone. Nests often go unseen and are typically found under rocks. It reaches an average body length of up to one inch long, the trait from which it received its common name.. The inchman is both a scavenger and a carnivore and it is the most poisonous species within its genus. When this species stings, it is similar the sting of a wasp or fire ant, causing anaphylaxis, which kills its prey. The first symptoms of a sting from this species include swelling and fever, with three percent of cases reporting anaphylaxis..

Interpretive Summary: The red imported fire ant was introduced into the United States in the 1930s and currently infests about 350 million acres. It causes economic losses that exceed 6 billion dollars annually in the United States and poses a threat to human health. SINV-3 is an RNA virus discovered recently by ARS scientists that infects the red imported fire ant. This virus causes fire ant mortality to such a degree that it makes experimental studies very difficult. USDA-ARS scientists at the Center for Medical, Agricultural and Veterinary Entomology (Gainesville, FL) have developed a rearing protocol permitting virus-free rearing of fire ants in the laboratory. This protocol is crucial to ongoing research on this invasive pest ant. Technical Abstract: During the initial characterization of ...
The reproductive success of individual fire ant queens (Solenopsis invicta) previously has been shown to be strongly influenced by their genotype at a single enzyme-encoding gene, designated Pgm-3. This paper presents evidence that a second, tightly linked gene, designated Gp-9, is under similarly strong selection in these ants. Selection appears to act independently on the two genes and is detectable in only one of the two social forms of this species (the "polygyne" social form, in which nests contain multiple fertile queens). Strong directional selection on Pgm-3 in this form involves worker destruction of all queens with genotype Pgm-3AA before they reproduce. Selection on Gp-9 is more complex, involving both lethality of all Gp-9bb females and a strong or even complete survival advantage to reproductive queens with the heterozygous genotype Gp-9Bb. Pgm-3 and Gp-9 are tightly linked (rf = 0.0016) and exhibit strong gametic phase disequilibrium in introduced populations in the U.S. This ...
Fire ants are aggressive ants that are known to group together and attack anyone or anything that disturbs their home. This often results in bites to both animals and people. The bites can be quite painful.
Ants are social insects, related to wasps and bees. Ants evolved from wasp-like ancestors 110 and 130 million years ago and diversified after the rise of flowering plants. More than 12,500 out of an estimated total of 22,000 species have been classified. They are easily identified by their elbowed antennae and a distinctive node-like structure that forms a slender waist. A few ants classified as pests include the pavement ant, yellow crazy ant, sugar ants, the Pharaoh ant, carpenter ants, Argentine ant, odorous house ants, red imported fire ant and European fire ant.. Ants are some of the strongest creatures comparative to their size. It has been documented that the common American field ant has joints that can withstand 5000 times its own body weight.. Most ants are harmless, although there are a few dangerous varieties. Fire ants are a kind of wingless wasp that has been known to kill humans. Velvet ants, which are also wingless wasps, are said to have one of the most painful stings in all of ...

When disturbed, two species of Malayan Pachycondyla release foam threads more than 10 cm in length or foam piles. The source of the proteinaceous foam is the enlarged venom gland, which is probably frothed up by air from the spiracles of the spiracular plates. The Dufours gland normally producing hydrocarbons in stinging ants is atrophied. Therefore, absence of the Dufours gland could be essential to the foaming ability, since the lipophilic hydrocarbons inhibit froth production in protein solutions. The release of foam is a mechanically acting defense mechanism, which is very effective against small mass-attacking ants. Pachycondyla species are also able to sting effectively. ...

Growing up in New Mexico, I was always quick to point out a film that was set, but not made, in my adopted state, called "Them!" The basic plot is that the early atomic tests conducted in New Mexico had caused ants to grow monstrously huge, and quite loud and noisy for never-heard ants.. I thought of that film again when Vicki Lawrence sent me an email with pictures of a giant ant. Now in comparison, this ant is nowhere near the mutant giants of "Them!" but compared to our tiny Argentine ants, its pretty darn large, about a half inch.. Vicki wondered if the ant was a local guy or one that had perhaps hitched a ride into the state and somehow ended up in her hallway.. The ant is a carpenter ant, the largest such ant that we have in California. Although its called a carpenter ant, it doesnt eat wood, it just builds its nest in rotting trees, old stumps, firewood and, if youre unlucky, inside any rotted or partially rotted wood in and on your house.. Seeing one in our house isnt reason to ...
While scientists have been tinkering with the genes of insects such as fruit flies for a long time, ants have proven to be a bigger challenge. In order to perform germline editing-genetic changes passed through generations-scientists have to modify the queen ant who lays the eggs. But there are some types of ants, such as clonal raiders, that reproduce asexually and without fertilization, producing clones of the mothers. Despite the trickiness, researchers at two different institutions recently succeeded in mutating ants. A study in Cell details how researchers genetically modified clonal raider ants using CRISPR, a gene-editing technique that allows for the cutting and/or pasting of gene sequences. In this study, scientists deactivated the orco gene, which facilitates the proper functioning of ants odorant receptors. When ants odorant receptors are disrupted, all of their olfactory genes suffer. Those receptors are crucial to ants social behavior-pheromones dictate how ants live and work ...

It was the initial impression by those who were with the patient, as well as the EMTs, she was experiencing an anaphylactic reaction to a spider bite. Although it is true, the most common allergens causing systemic anaphylactic reactions include drugs, peanuts, tree nuts, insect venoms, foods, radiocontrast media, allergen immunotherapy injections, and latex. In addition, Hymenopteran (winged insects, such as sawflies, wasps, bees and ants) stings alone are responsible for most arthropod related deaths and usually result from the development of hypersensitivity following repeated exposure to venom. The question that needs to be asked is what types of reactions do spider bites in North America cause. Spiders belong to the order Araneae, which are airbreathing arthropods that have eight legs and chelicerae with fangs that inject venom. There are two spiders of immediate concern in North America, The black widow spider, Latrodectus mactans, and the brown recluse spider, the most famous of which is ...

  • The results confirm the response of P. tricuspis to physiologically relevant amounts of the two venom alkaloid fractions ( cis and trans alkaloid fractions) of S. invicta. (harvard.edu)
  • Further analysis by coupled gas chromatography-electroantennogram detection revealed nine venom alkaloid components including two novel 2,6-dialkylpiperideines that elicited significant antennal activity in P. tricuspis. (harvard.edu)
  • The venom only has four protein allergens, which have been extensively investigated: this includes Sol i 2 and 4, which are not similar to other characterised proteins and have not been described in other insect venoms. (wikipedia.org)
  • First, we tested the electroantennogram response of P. tricuspis to extracts of key body parts and glands of workers of the red imported fire ant, S. invicta Buren. (harvard.edu)
  • A survey conducted in China shows that one-third of participants in infested areas were victims of red imported fire ant stings. (wikipedia.org)
  • Fire Ant Venom: The Next Ingredient in Skin Care Products? (labroots.com)
  • A unique quality of the main toxic "ingredient" in fire ant venom makes it the newest, if unlikely, candidate for treating an autoimmune skin disorder, psoriasis. (labroots.com)
  • The most recent study has only finished trials in mouse models of the disease, but if clinical trials in humans are also successful - and safe - fire ant venom could be the solution a lot of psoriasis patients have been looking for. (labroots.com)
  • Solenopsins from fire ant venom have been subjects of study before. (labroots.com)
  • The toxicology of red imported fire ant venom has been extensively studied. (wikipedia.org)
  • The venom is important to the red imported fire ant, enabling it to capture its prey and to defend itself. (wikipedia.org)
  • Venom plays an important role in a red imported fire ant colony, being used to capture prey items, for defence, and antimicrobial action. (wikipedia.org)
  • In the United States, more than 40 million people live in areas infested with fire ant populations and 14 million people are stung by them annually. (wikipedia.org)
  • A quarter of all victims stung by red imported fire ants are expected to develop sensitivity to the venom, and approximately 6,000 will suffer anaphylaxis. (wikipedia.org)
  • In a survey conducted in South Carolina, 33,000 people (or 94 per 10,000 population) received medical attention due to red imported fire ants, and 660 people (1.9 per 10 000 population) were treated for anaphylaxis. (wikipedia.org)
  • In Texas, 79% of participants in a survey stated they had been stung by red imported fire ants, while 20% had not. (wikipedia.org)
  • In Australia, 64,000 homes are within red imported fire ant infested areas, and 140,000 consultations and 3,000 anaphylactic reaction cases are predicted every year by 2030 if government efforts to eradicate the ant fail. (wikipedia.org)
  • The phorid fly, Pseudacteon tricuspis Borgmeier, is an introduced parasitoid of imported fire ants, Solenopsis spp. (harvard.edu)
  • Although the assumption that phorid flies use fire ant alarm pheromones for host location is probably true, we demonstrated in a previous study the possible involvement of other ant semiochemicals in the response of P. tricuspis to fire ants. (harvard.edu)
  • Venom from the giant red bull ant is helping University of Queensland scientists understand the evolution of animal toxins in work that could lead to better treatments for pain. (healthcanal.com)
  • Researchers from UQ's Centre for Advanced Imaging and Institute for Molecular Bioscience have completed the first comprehensive study of ant venom, revealing toxins that stimulate the human nervous system to cause pain. (healthcanal.com)
  • Piperidines include trans-2-methyl-6-n-undecylpiperidines, trans-2-Methyl-6-n-tridecylpiperidine, trans-2-Methyl-6-(cis-4-tridecenyl) piperidines, trans-2-methyl-6-n-pentadecylpiperidine, trans-2-methyl-6-(cis-6-pentadecenyl)piperidine and 2,6-dialkylpiperidines (the ants' venom is dominated by the trans stereoisomers of this specific ingredient). (wikipedia.org)
  • That means we can use animal venoms to study the human nervous system and learn more about how pain travels through the body and how to develop compounds that block it. (healthcanal.com)
  • These components are responsible for the formation of hives, and also for the development of sterile pustules on areas where the ant has stung. (wikipedia.org)
  • Workers deliver 0.66 nl of venom when they sting, which amounts to 3.1% of their supply. (wikipedia.org)
