Arthropods of the class ARACHNIDA, order Araneae. Except for mites and ticks, spiders constitute the largest order of arachnids, with approximately 37,000 species having been described. The majority of spiders are harmless, although some species can be regarded as moderately harmful since their bites can lead to quite severe local symptoms. (From Barnes, Invertebrate Zoology, 5th ed, p508; Smith, Insects and Other Arthropods of Medical Importance, 1973, pp424-430)
Membrane-bound compartments which contain transmitter molecules. Synaptic vesicles are concentrated at presynaptic terminals. They actively sequester transmitter molecules from the cytoplasm. In at least some synapses, transmitter release occurs by fusion of these vesicles with the presynaptic membrane, followed by exocytosis of their contents.
Purification from black widow spider venom of a protein factor causing the depletion of synaptic vesicles at neuromuscular junctions. (1/36)The aqueous extract of the venom glands of black widow spiders was fractionated on a column of Sephadex G-200 and then on a column of DEAE-Sephadex A-50 pH 8.2. A protein fraction was obtained that caused a great increase in the frequency of occurrence of miniature end plate potentials at the frog neuromuscular junction, and caused swelling of the nerve terminals and depleted them of their vesicles. The fraction consists of a least four protein components that are similar in their molecular weights (about 130,000) and isoelectric points (ranging from pH 5.2 to 5.5) and are immunologically indistinguishable. It contains no sugar residues and has little or no lipolytic or proteolytic activity. The fraction is toxic to mice and is different from the fractions that act on houseflies, the crayfish stretch receptor and the cockroach heart. It seems pure enough to warrant a detailed study of its site and mode of action. (+info)
Black widow bites in children. (2/36)While seldom lethal, the bite of the black widow spider causes serious systemic symptoms that appear suddenly and progress rapidly. Children are more vulnerable to these complications; therefore, early hospitalization and aggressive therapy must be considered. General information about the widow spider genus is presented, and an illustrative case and treatment options are discussed. (+info)
Latrodectus bites in northern Dalmatia, Croatia: clinical, laboratory, epidemiological, and therapeutical aspects. (3/36)AIM: To analyze clinical and epidemiological characteristics of the black widow spider (Latrodectus tredecimguttatus) bites and asses the impact of antitoxin administration after the bite on the intensity and duration of pain. METHOD: Retrospective analysis of clinical appearance, laboratory findings, and clinical assessment of the antitoxin administration efficacy in 32 patients with latrodectism treated at Zadar General Hospital between 1992 and 2002. RESULTS: All patients presented with generalized pain, profound perspiration, and burning in the sole of the foot. Laboratory findings revealed moderately increased serum glucose concentrations in half of the patients, concentrations of aspartate aminotransferase and alanine aminotransferase 2 to 3 times higher than normal in 8 of 32 patients, moderate leukocytosis in 16 of 32 patients, mature neutrophilia in 15 of 32 patients, and immature forms of leukocytes in 4 of 32 patients. In 21 patients who received the antitoxin, severe pain lasted 1-4 h (median, 1.2 h) after the antitoxin administration, moderate pain 1-5 h (median, 2.4 h), and hospitalization 1-5 days (median, 4 days). In patients who did not receive antitoxin, there was a statistically significant increase in duration of severe pain (median, 50 h; range, 24-72 h), moderate pain (median, 36 h; range, 24-48 h), and hospitalization (median, 6 days; range, 4-12 days) (p<0.05 for all, Kruskal-Wallis H test). Men were more often bitten by the venomous spider (20 men vs 12 women); adults more often than children (30 vs 2, respectively), domestic population more often than tourists (30 vs 2, respectively), and rural mainland inhabitants more often than islanders (21 vs 11, respectively). All biting incidents occurred between June and September, most often in July (17 patients). CONCLUSION: Latrodectism in Northern Dalmatia presents with severe clinical symptoms. Administration of the antitoxin is advisable in the treatment of all afflicted patients. (+info)
Mutant alpha-latrotoxin (LTXN4C) does not form pores and causes secretion by receptor stimulation: this action does not require neurexins. (4/36)Alpha-latrotoxin (LTX) causes massive release of neurotransmitters via a complex mechanism involving (i) activation of receptor(s) and (ii) toxin insertion into the plasma membrane with (iii) subsequent pore formation. Using cryo-electron microscopy, electrophysiological and biochemical methods, we demonstrate here that the recently described toxin mutant (LTXN4C) is unable to insert into membranes and form pores due to its inability to assemble into tetramers. However, this mutant still binds to major LTX receptors (latrophilin and neurexin) and causes strong transmitter exocytosis in synaptosomes, hippocampal slice cultures, neuromuscular junctions, and chromaffin cells. In the absence of mutant incorporation into the membrane, receptor activation must be the only mechanism by which LTXN4C triggers exocytosis. An interesting feature of this receptor-mediated transmitter release is its dependence on extracellular Ca2+. Because Ca2+ is also strictly required for LTX interaction with neurexin, the latter might be the only receptor mediating the LTXN4C action. To test this hypothesis, we used conditions (substitution of Ca2+ in the medium with Sr2+) under which LTXN4C does not bind to any member of the neurexin family but still interacts with latrophilin. We show that, in all the systems tested, Sr2+ fully replaces Ca2+ in supporting the stimulatory effect of LTXN4C. These results indicate that LTXN4C can cause neurotransmitter release just by stimulating a receptor and that neurexins are not critical for this receptor-mediated action. (+info)
Egg case protein-1. A new class of silk proteins with fibroin-like properties from the spider Latrodectus hesperus. (5/36)Spiders produce multiple types of silk that exhibit diverse mechanical properties and biological functions. Most molecular studies of spider silk have focused on fibroins from dragline silk and capture silk, two important silk types involved in the survival of the spider. In our studies we have focused on the characterization of egg case silk, a third silk fiber produced by the black widow spider, Latrodectus hesperus. Analysis of the physical structure of egg case silk using scanning electron microscopy demonstrates the presence of small and large diameter fibers. By using the strong protein denaturant 8 M guanidine hydrochloride to solubilize the fibers, we demonstrated by SDS-PAGE and protein silver staining that an abundant component of egg case silk is a 100-kDa protein doublet. Combining matrix-assisted laser desorption ionization tandem time-of-flight mass spectrometry and reverse genetics, we have isolated a novel gene called ecp-1, which encodes for one of the protein components of the 100-kDa species. BLAST searches of the NCBInr protein data base using the primary sequence of ECP-1 revealed similarity to fibroins from spiders and silkworms, which mapped to two distinct regions within the ECP-1. These regions contained the conserved repetitive fibroin motifs poly(Ala) and poly(Gly-Ala), but surprisingly, no larger ensemble repeats could be identified within the primary sequence of ECP-1. Consistent with silk gland-restricted patterns of expression for fibroins, ECP-1 was demonstrated to be predominantly produced in the tubuliform gland, with lower levels detected in the major and minor ampullate glands. ECP-1 monomeric units were also shown to assemble into higher aggregate structures through the formation of disulfide bonds via a unique cysteine-rich N-terminal region. Collectively, our findings provide new insight into the components of egg case silk and identify a new class of silk proteins with distinctive molecular features relative to traditional members of the spider silk gene family.

Quasistatic and continuous dynamic characterization of the mechanical properties of silk from the cobweb of the black widow spider Latrodectus hesperus. (6/36)Spider silks are among the strongest and toughest known materials, but investigation of these remarkable properties has been confined largely to orb-weaving spiders. We investigated the mechanical performance of silk from the cobweb-weaving spider Latrodectus hesperus. Both silk from the scaffolding region of the web and sticky gumfooted capture lines had material properties similar to the major ampullate silk that orb weavers use as the framework for their orb webs. Major ampullate fibers obtained from anaesthetized Latrodectus spiders were similar, but exhibited increased stiffness and reduced extensibility. Novel continuous dynamic analysis of the silks revealed that the loss tangent (tandelta) increased rapidly during the first 2-3% of extension and reached a maximum near the yield point of fibers. The loss tangent then rapidly declined at an ever-decreasing rate until failure. We suggest that these data support molecular models for the mechanics of spider silk. We also demonstrate that the addition of sticky aggregate glue to the ends of the gumfooted lines modulates their mechanical performance--reducing stiffness and increasing extensibility. The storage modulus of viscid regions of the gumfooted lines was much lower than dry regions. This may be explained by disruption of hydrogen bonding within the amorphous regions of the fibers due to hydration from the glue. (+info)
Vitamin B1 thiazole derivative reduces transmembrane current through ionic channels formed by toxins from black widow spider venom and sea anemone in planar phospholipid membranes. (7/36)The vitamin B1 (thiamine) structural analogue 3-decyloxycarbonylmethyl-4-methyl-5-(beta-hydroxyethyl) thiazole chloride (DMHT) (0.1 mM) reversibly reduced transmembrane currents in CaCl2 and KCl solutions via ionic channels produced by latrotoxins (alpha-latrotoxin (alpha-LT) and alpha-latroinsectotoxin (alpha-LIT)) from black widow spider venom and sea anemone toxin (RTX) in the bilayer lipid membranes (BLMs). Introduction of DMHT from the cis-side of BLM bathed in 10 mM CaCl2 inhibited transmembrane current by 31.6+/-3% and by 61.8+/-3% from the trans-side of BLM for alpha-LT channels. Application of DMHT in the solution of 10 mM CaCl2 to the cis-side of BLM decreased the current through the alpha-LIT and RTX channels by 52+/-4% and 50+/-5%, respectively. Addition of Cd2+ (1 mM) to the cis- or trans-side of the membrane after the DMHT-induced depression of Ca2+-current across the alpha-LT channels caused its further decrease by 85+/-5% that coincides favorably with the intensity of Cd2+ blocking in control experiments without DMHT. These data suggest that DMHT inhibiting is not specific for latrotoxin channels only and DMHT may exert its action on alpha-LT channels without considerable influence on the ionogenic groups of Ca2+-selective site inside the channel cavity. The binding kinetics of DMHT with the alpha-LT channel shows no cooperativity and allows to expect that the DMHT binding site of the toxin is formed by one ionogenic group as the slopes of inhibition rate determined in log-log coordinates are 1.25 on the trans-side and 0.68 on the cis-side. Similar pK of binding (5.4 on the trans-side and 5.7 on the cis-side) also suggest that DMHT may interact with the same high affinity site of alpha-LT channel on either side of the BLM. The comparative analysis of effective radii measured for alpha-LT, alpha-LIT and RTX channels on the cis-side (0.9 nm, 0.53 nm and 0.55 nm, correspondingly) and for alpha-LT channel on the trans-side (0.28+/-0.18 nm) with the intensity of DMHT inhibitory action obtained on these channels allowed to conclude that the potency of DMHT inhibition increased on toxin pores of smaller lumen.

Insecticidal toxins from black widow spider venom. (8/36)The biological effects of Latrodectus spider venom are similar in animals from different phyla, but these symptoms are caused by distinct phylum-specific neurotoxins (collectively called latrotoxins) with molecular masses ranging from 110 to 140 kDa. To date, the venom has been found to contain five insecticidal toxins, termed alpha, beta, gamma, delta and epsilon-latroinsectotoxins (LITs). There is also a vertebrate-specific neurotoxin, alpha-latrotoxin (alpha-LTX), and one toxin affecting crustaceans, alpha-latrocrustatoxin (alpha-LCT). These toxins stimulate massive release of neurotransmitters from nerve terminals and act (1) by binding to specific receptors, some of which mediate an exocytotic signal, and (2) by inserting themselves into the membrane and forming ion-permeable pores. Specific receptors for LITs have yet to be identified, but all three classes of vertebrate receptors known to bind alpha-LTX are also present in insects. All LTXs whose structures have been elucidated (alpha-LIT, delta-LIT, alpha-LTX and alpha-LCT) are highly homologous and have a similar domain architecture, which consists of a unique N-terminal sequence and a large domain composed of 13-22 ankyrin repeats. Three-dimensional (3D) structure analysis, so far done for alpha-LTX only, has revealed its dimeric nature and an ability to form symmetrical tetramers, a feature probably common to all LTXs. Only tetramers have been observed to insert into membranes and form pores. A preliminary 3D reconstruction of a delta-LIT monomer demonstrates the spatial similarity of this toxin to the monomer of alpha-LTX. (+info)

Latrodectism - Wikipedia
Latrodectism is the illness caused by the bite of Latrodectus spiders (the black widow spider and related species). Pain, muscle rigidity, vomiting, and sweating are the symptoms of latrodectism. Contrary to popular conception, latrodectism is very rarely fatal to people though domestic cats have been known to die with convulsion and paralysis. There are several spider species all named black widow: southern black widow spider (L. mactans), the European black widow (L. tredecimguttatus), Western black widow spider (L. hesperus), Northern black widow spider (L. variolus). Other Latrodectus that cause latrodectism are the Australian redback spider (L. hasselti), and the New Zealand katipo spider (L. katipo). Several other members of Latrodectus genus are not commonly associated with latrodectism including the cosmopolitan brown widow (L. geometricus). A bite of Latrodectus may not inject any venom (known as a dry bite) and so no illness occurs. About 75% of wet bites will have localized pain and ...

Spider Control & Extermination - Defense Pest Control Service
The black widow spider is notoriously known to many since childhood. The males are harmless and generally smaller than the females. Males do not carry the red hour-glass shape alerting folks of the danger venomous female black widow spiders possess. Generally, black widow spiders are not aggressive, and will only bite if they have no escape and feel threatened. Not only do the females carry the distinctive red or sometimes yellow or orange hourglass shape, but they appear to be a shiny black color. The females abdomen is also rounder than the males. The black widow generally constructs her sleek and durable web, which typically measures a foot wide, in dark garages, old sheds and other structures, or other undisturbed places. If they should stick to the outdoors, you can find her nestling in abandoned animal burrows, in stumps, or behind or within woodpiles. If you are bitten by a black widow you can expect excruciating pain, swelling, redness, abdominal discomfort, headaches and sweating. ...

Effects of Latrodectus spider venoms on sensory and motor nerve terminals of muscle spindles | Proceedings of the Royal Society...
The effects of the venoms of the spiders Latrodectus mactans tredecimguttatus (black widow) and Latrodectus mactans hasselti (red back) on sensory nerve terminals in muscle spindles were studied in the mouse. A sublethal dose of venom was injected into tibialis anterior and extensor digitorum longus muscles of one leg. After survival from 30 minutes to 6 weeks muscles were examined in serial paraffin sections impregnated with silver or by electron microscopy. Sensory endings became swollen, some within 30 minutes, while over the next few hours there was progressive degeneration of annulospiral endings. By 24 hours every spindle identified by light or electron microscopy was devoid of sensory terminals. Degenerated nerve endings were taken up into the sarcoplasm of intrafusal muscle fibres. Regener-ation of sensory axons began within 24 hours, new incomplete spirals were formed by 5 days and by 1 week annulospiral endings were almost all normal in appearance. Intrafusal motor terminals underwent ...

Toxins | Free Full-Text | Isolation and Preliminary Characterization of Proteinaceous Toxins with Insecticidal and...
The eggs of black widow spider (L. tredecimguttatus) have been demonstrated to be rich in toxic proteinaceous components. The study on such active components is of theoretical and practical importance. In the present work, using a combination of multiple biochemical and biological strategies, we isolated and characterized the proteinaceous components from the aqueous extract of the black widow spider eggs. After gel filtration of the egg extract, the resulting main protein and peptide peaks were further fractionated by ion exchange chromatography and reversed-phase high performance liquid chromatography. Two proteinaceous components, named latroeggtoxin-III and latroeggtoxin-IV, respectively, were purified to homogeneity. Latroeggtoxin-III was demonstrated to have a molecular weight of about 36 kDa. Activity analysis indicated that latroeggtoxin-III exhibited neurotoxicity against cockroaches but had no obvious effect on mice, suggesting that it is an insect-specific toxin. Latroeggtoxin-IV, with a

ACVC 2001 - Natural Does Not Mean Safe
Latrodectus spp. or black widow spiders are globose black spiders with an hour-glass red-orange abdominal pattern. They are widely distributed in the US. Single bites are potentially fatal especially to sensitive species such as cats. Clinical signs include progressive muscle fasiciculations, severe pain, muscle cramping, abdominal rigidity without tenderness, restlessness, hypertension, bronchorrhea, regional numbness and hypersalivation. The venom of black widow spiders contains several biologically active proteins one of which, a-latrotoxin, induces neurotransmitter release from nerve terminals. Acetylcholine, noradrenaline, dopamine, glutamate and enkephalin systems are all affected. There are no confirmatory tests that are available. One clue in cats: they may vomit up the spider. Early identification of bites is difficult unless the bite is actually witnessed. Treatment includes the administration of a specific antivenin (Lyovac , equine origin from Merck) by slow i.v. infusion. Allergic ...
