2014b). However, if there is a risk a sting is from a Portuguese man-of-war, using a chemical can cause all of the stinging cells to fire at once and worsen the injury. 2013), parasitoid wasps (Perkin et al. 2014b). In nematodes, cystatins modulate host immune response and can act as proinflammatory molecules whereas tick and leech cystatins are antihemostatic effectors involved in blood feeding (Hartmann and Lucius 2003; Kvist et al. 2014b; Modica et al. My wife and I were diving at a site called Weber’s Joy on our last trip to Bonaire. The Bristles You Must Banish - Fireworm Identification Tip. Ctenitoxins are neurotoxins that contain an inhibitor cysteine-knot motif, first identified from the venom of the hunting spider Cupiennius salei that act as L-type calcium channel inhibitors but also show cytolytic activity (Kubista et al. Tree reconstructed with RAxML-HPC-PTTHREADS v8.2.10 and support values estimated through a rapid bootstrap algorithm and 1,000 pseudoreplicates. 2009; Choo et al. 2012; Xia et al. and Sipunculus nudus) and a mollusk (Chiton olivaceus), recovering only 18 putative toxins in Chaetopterus sp. 2015) whereas in Glycera bloodworms they are thought to be involved in paralysis and death of prey (von Reumont et al. 1996; Kini 2003; Veiga et al. S5, Supplementary Material online). 2007; Santos et al. Serpin homologs were also recovered among the putative fireworm toxins. 2009; Wong et al. An individual of Hermodice carunculata was collected by SCUBA from Norman’s Pond Cay Cave, Norman’s Pond Cay, Exumas, Bahamas (GPS N 23 47.181, W 076 08.428) and transported back to the field station where it was flash frozen in liquid nitrogen. Both alcohol and vinegar are standard in a diving first aid kit. The expression of metalloproteinase M12 and phospholipases could also explain the reported cases of local necrosis. Our results show that the species E. complanata, H. carunculata, and P. jeffreysii express a wide diversity of transcripts coding for toxin homologs that have been repeatedly recruited into animal venoms, including protease inhibitors, proteolytic enzymes, and neurotoxins (figs. 3 and 4). They are slow-moving and very photogenic. 2004; Whittington et al. After this second comparison, we filter out the toxin-like transcripts that are more similar to other genes with nonvenom-related functions. Fireworm stings produce localized reactions with a variety of symptoms that include strong skin inflammation or edema, acute and severe pain, intense itching, partial paresthesia, or numbness of the affected area and sometimes serious wound infections and local necrosis (Smith 2002; Nakamura et al. A person becomes infected when they drink water that contains water fleas infected with guinea worm larvae. http://en.wikipedia.org/wiki/Bearded_fireworm. The scheme is the same, only the larvae on the same amount of alcohol will need twice as much. Tilic et al. 2010; Vaiyapuri et al. Representatives of species that use venom for predation are also shown, highlighted in blue: bloodworm Glycera capitata (E) and leech Helobdella europaea (F). 2008, 2010; Borda et al.

Similarly, fireworms (Amphinomidae) (fig. 1A–C) which are common in shallow warm and temperate waters and include colorful reef-dwelling species, are well-known among divers and reef enthusiasts for their painful sting (Wiklund et al. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. Thus, guaranteeing the best BLAST hit for all our toxin candidates is a known venom protein. 2013). He hid in the rocks all day. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. ... seabeast with an agonising sting is dragged from the deep ... anti-masker at a hair salon and gave him her courtroom treatment 2017). 2005; Fry et al. Get some tape stick, it over the area and peel it off. 2009; Undheim et al. 2013). Abbreviations are as follows: CLEC, C-type lectin; M12, metalloproteinase M12; PEP S1, peptidase S1; PEP S10, peptidase S10; PL, phospholipase; ShK, ShKT-domain containing peptides; AChE, acetylcholinesterase; SMase, sphingomyelinase. In snake venom, CAP proteins function as ion channel modulators inhibiting smooth muscle contraction (Yamazaki and Morita 2004), whereas in cone snails they have proteolytic activity (Milne et al. They'll help protect against minor jelly stings and sea lice. 2005; Takác et al. The three fireworms share a similar toxin profile, with C-type lectin being the most diverse toxin class in all cases, and peptidase S1, metalloproteinase M12, spider toxin, and CAP found among the most highly expressed toxin homologs, altogether representing ∼60% of all putative toxins identified (fig. 3). Actinoporin and gigantoxin are highly conserved pore-forming toxins initially identified in sea anemones that show cytolytic, hemolytic, and nerve stimulatory activity (Anderluh and Maček 2002; Hu et al. Tree reconstructed with RAxML-HPC-PTTHREADS v8.2.10 and support values estimated through a rapid bootstrap algorithm and 1,000 pseudoreplicates. A variety of phospholipase homologs have also been detected among the putative fireworm toxins. Chmelař J, Kotál J, Langhansová H, Kotsyfakis M. Cuypers E, Peigneur S, Debaveye S, Shiomi K, Tytgat J. Darriba D, Taboada GL, Doallo R, Posada D. Fernández J, Gutiérrez JM, Calvete JJ, Sanz L, Lomonte B. Gorson JM, Verdes A, Shin H, Khawaja S, Holford M. Irving JA, Pike RN, Lesk AM, Whisstock JC. To treat the sting of a Fireworm you must remove the bristles, however, tweezers wont be effective at this. 2005; Magalhães et al. Gustafson (1930) attributed the toxicity of fireworms to a clear gelatinous substance filling the chaetal core, while Schulze et al. It has long been hypothesized that amphinomids are venomous and use the chaetae to inject a toxic substance. Bootstrap support values are given for all nodes and clade names are indicated by colored squares. very small, about an inch long. Bearded fireworm (Busuf), Hermodice carunculata. 2001). 2014b) and from public databases as mentioned earlier. 2014). Kazal-domain and Kunitz-type protease inhibitors are also among the most diverse toxin homologs expressed in the transcriptomes of H. carunculata and E. complanata (fig. 3A and B), whereas in P. jeffreysii spider neurotoxins including agatoxin, ctenitoxin, hainantoxin, and latrotoxin homologs are the second most diverse expressed putative toxins (fig. 3C). Lipocalins have also been identified as major allergens inducing severe anaphylactic reactions in humans after hematophagous insect bites (Paddock et al. The putative kazal-type fireworm toxins are found in several clades across the tree, mainly clustering with kazal-type toxins recovered from the venom gland of Glycera bloodworms (von Reumont et al. 2015; Phuong et al. 2000; Rouse and Pleijel 2001) that share a series of morphological apomorphies such as nuchal organs on a sensory structure referred to as the caruncle, a ventral muscular eversible proboscis with thickened cuticle on circular lamellae, and calcareous chaetae (Rouse and Fauchald 1997; Wiklund et al. 1985; von Reumont et al. This is the first molecular comparative analysis identifying toxin-like genes in fireworm transcriptomes. nano.

Seek medical treatment if needed. Interestingly, the Eurythoe and Paramphinome putative cystatins do not cluster with other cystatin homologs from nonvenomous annelids (Capitella and Perinereis) suggesting the involvement of this protein in fireworm toxicity. 2016), the lower diversity of toxin homologs recovered from some species might also be explained by differences in library construction methods and sequencing depth between the three transcriptomes (see supplementary table S1, Supplementary Material online). It hurt like ---- for the rest of the day. Fauna of Australia. 2015; Gorson et al. 2016). Over the weekend he disappeared. The Hermodice cystatin-like genes are found elsewhere in the tree more closely related to other cystatins from nonvenomous taxa. Kaas Q, Yu R, Jin AH, Dutertre S, Craik DJ. —Phylogenetic tree of ShKT-domain containing peptides. Sequences from nonvenomous taxa are indicated with closed circles and fireworm homologs are highlighted in bold. Both leeches and bloodworms use venom to assist in feeding. Transcripts were searched using the BLASTP tool (Altschul 1997; Johnson et al. See supplementary table S2, Supplementary Material online, for accession numbers. Aiptasia is a monster of a problem for some. The following step is a homology search (blue) using three different search strategies based on BLAST, HMMER-sequence and HMMER-domain. 2009; Casewell et al. 2013; Junqueira-de-Azevedo et al. When pulling it from the skin, it will also grab and pull the bristles from the skin and stop further irritation. A golden fireworm sting may result in this: Transcripts initially identified as putative toxins were included in the final candidate toxin list only if 1) the best hit from the UniProtKB/Swiss-Prot database had a higher e-value than the initial hit from the venom database or HMM profile, or 2) the best hit from the UniProtKB/Swiss-Prot database was labeled as a toxin.

Treatment for a bristleworm sting includes the following: Remove bristles with tweezers or adhesive tape. Sequences from nonvenomous taxa are indicated with closed circles and fireworm homologs are highlighted in bold. All fireworm sequences cluster in one large clade that also includes the bloodworm sequences, which might suggest an annelid specific radiation of this protein class (supplementary fig. We have recovered 27 phospholipase-like genes that belong to two orthologous clusters, one of them corresponding to phospholipase B homologs and the other including phospholipase A2 homologs. The numerous protease inhibitors (i.e., cystatin, lipocalin, serpin, kazal, and kunitz-type), proteolytic enzymes (metalloproteinase M12 and peptidase S1), and C-type lectins found in H. carunculata, E. complanata, and P. jeffreysii fireworms mainly interfere with hemostatic processes and the inflammatory response (fig. 4), and therefore their activities are consistent with the strong skin inflammation, edema, and intense pain that occur after fireworm stings. 2008; Perkin et al. 2017), remipede crustaceans (von Reumont et al. 1995; Castañeda and Harvey 2009) and have been posteriorly reported from a variety of proteins including venom toxins from other cnidarians, snakes, ribbon worms, vampire snails, and bloodworms (von Reumont et al. —Phylogenetic tree of metalloproteinase M12 sequences. 2015; Perkin et al. 2015). S3, Supplementary Material online) and interestingly, a particularly large clade that includes transcripts from all three fireworm species and two Glycera species also includes serine proteases identified from the posterior venom glands of the cephalopod Octopus kaurna (Fry et al. In addition to the predatory use of venom, there are also annelids that utilize toxins as a defensive mechanism (fig. 1A–D). The three de novo assembled fireworm transcriptomes were analyzed to identify putative toxins and venom components following a custom in silico venomics pipeline modified from Verdes et al. Although the presence of a venom delivery mechanism, which is a clear feature distinguishing venomous versus poisonous animals, has yet to be confirmed in fireworms, other criteria can provide evidence of their venomous nature. Despite this difficulty, we provide several lines of evidence that strongly suggest the sequences we identified here are likely coding for putative toxins. Charles Hecht is a chiropractor practicing in Chapel Hill, NC. ShKT-domain containing peptide phylogeny including sequences from venomous and nonvenomous taxa and fireworm homologs. 2014; Andrade et al. The predicted signal sequence is delimited by a yellow square and the Kazal domain is delineated by a purple square. Interestingly, one Paramphinome transcript (PJKAZ1) clusters with Vasotab, a kazal-type inhibitor identified from the salivary glands of the horse fly Hybomitra bimaculata that functions as a vasodilator (Takác et al. However, there is a small chance that a more dangerous species (the fire worm) made its way into your tank. S6, Supplementary Material online). Some of the fireworms, called bearded fireworms, are lined with fine white hairs. 2017). He enjoys spending time with his wife and dog, as well as playing tennis, working out, and scuba diving. In the vampire snail Colubraria reticulata, ShKT toxins might act as anesthetics (Modica et al. 2008, 2012) or Tox-Prot (Jungo and Bairoch 2005; Jungo et al. 2007; Lopes-Ferreira et al. Phylogenetic tree of Kazal-type protease inhibitors. 2017), and glycerid bloodworms (von Reumont et al. 2014b). 2008; Ding et al.

We initially identified putative toxins based on sequence similarity to known toxins and venom proteins, but because this method can also yield nontoxin homologs, we further validated these candidates by comparing them to the entire UniProtKB database. I bought a Hectors goby. 2016). A cross section of the posterior end of the animal was dissected for total RNA extraction. (2017) found evidence of fluid being released from chaetal tips and identified grooved chaetae under the scanning electron microscope, indicating a possible alternative for toxin delivery. We would like to thank Juliette Gorson, Carlos Lijeron, Ntino Krampis, Yi Wang, and Laurel Yee for their assistance with bioinformatics analyses. Turripeptides function as neurotoxins modulating ion channels and causing disruption of the neuromuscular transmission, which leads to paralysis of prey (Aguilar et al. Casewell NR, Wüster W, Vonk FJ, Harrison RA, Fry BG. The conflicting evidence regarding the possible function of the calcareous chaetae as a toxin delivery system and the fact that no secretory tissue has been identified near the base of the chaetae has generated doubt about the venomous nature of fireworms (Tilic et al. In the venom, peptidase S1 serine proteases show varied activities such as anticoagulation, vasodilation, smooth muscle contraction, pain, immunosuppression, and inflammation (von Reumont et al. However, the rise of -omics technologies, such as genomics, transcriptomics, and proteomics, has led to a revival of venom studies using an integrated approach referred to as venomics. In parallel, transcripts were also searched using HMMER (Finn et al. 2017). MH acknowledges funding from the Camille and Henry Dreyfus Teacher-Scholar Award and NSF awards CHE-1247550 and CHE-1228921. The M12 family of zinc dependent metalloproteinases has been widely recruited into the venoms of many taxa including snakes, platypus, scorpions, spiders, cnidarians, cephalopods, mollusks, leeches, and bloodworms (Da Silveira et al. Vol 4A. 2013; Bose et al. Seek medical treatment if … 2014b). Phylogenetic analyses of individual toxin families including amphinomid homologs were performed to validate the orthology predictions derived from the venomics pipeline and to investigate toxin evolutionary relationships and possible origins. We believe the findings in the nonvenomous organisms provide validation for the specificity of our pipeline and indicate that most of the sequences identified in the fireworms are more likely coding for venom toxins rather than for nontoxin homologs, suggesting only a minor percentage might represent false positives. If the irritation continues, hydrocortisone cream can be applied to the wound, and if an infection is suspected, a topical antibiotic can be applied.

Amphinomids, more commonly known as fireworms, are a basal lineage of marine annelids characterized by the presence of defensive dorsal calcareous chaetae, which break off upon contact. —Diversity of toxin homologs identified in each fireworm species. This was 3 weeks ago. 2004). Venomous animals on the contrary, produce venom proteins endogenously by expressing specific gene products (Fry et al. Diagram of the bioinformatics pipeline followed to identify putative venom components in fireworms. The tissue was homogenized in TriZol reagent (Life Technologies, NY) and total RNA was precipitated with isopropanol and dissolved in distilled water. 2013; Gorson et al. Bootstrap support values are given for all nodes and clade names are indicated by colored squares. An allergic reaction to fireworm venom is always a possibility. Abbreviations are as follows: CLEC, C-type lectin; M12, metalloproteinase M12; PEP S1, peptidase S1; PEP S10, peptidase S10; PL, phospholipase; ShK, ShKT-domain containing peptides. 2015; Ponce et al. 2013). 5. Lipocalins are small extracellular proteins that bind small hydrophobic molecules and show great functional diversity including roles in retinol and pheromone transport, olfaction, prostaglandin synthesis, cell homeostasis, and modulation of the immune response (Flower 1996). 2011) against hidden Markov models (HMM) profiles built from alignments of 24 known venom protein classes derived from a recent study of bloodworm (Glyceridae) venom gland transcriptomics (von Reumont et al. The symptoms can last several days or even weeks and the recommended treatment includes applying vinegar and hot water to the affected area (Smith 2002; Schulze et al. Lice feed by biting and drinking the blood of their hosts. —Phylogenetic tree of cystatin sequences. When pulling it from the skin, it will also grab and pull the bristles from the skin and stop further irritation. 'That bearded fireworm was not messing around,' the angler added. We are thankful to Anne Weigert and Torsten Struck for sharing transcriptome data for E. complanata and P. jeffreysii before it was publicly available. Applying the venomics strategy to elucidate animal venom composition has revealed a high genetic and functional diversity of venom compounds across different taxa, and the molecular processes responsible for it (Vonk et al. Total RNA and the resulting cDNA library were assessed for quality and concentration with the Agilent 2100 BioAnalyzer and with agarose gel electrophoresis. 2015). The kind of bristle worm that you really need to focus on keeping away from your aquarium fish is the “fireworm” family. and none in S. nudus or C. olivaceus (see supplementary table S1, Supplementary Material online). Give the same first aid as that given for other venomous fish. 2016), sea anemones and cone snails (Schweitz et al. Amphinomidae has been traditionally placed within Errantia (Rouse and Fauchald 1997) until recent molecular studies revealed their phylogenetic position as sister group, together with Sipuncula, to all Pleistoannelida (Sedentaria + Errantia) (Weigert et al. 2017), a common remedy for marine envenomations as evidence suggests that heat inactivates key components of the venom (Wilcox and Yanagihara 2016). 2014b). ( Log Out /  2015), and a variety of insects like bees, wasps, ticks, flies (Yang et al. 2015), leeches, and bloodworms (Kvist et al. 2016). Carrying poison in their feet is a successful defense for fireworms. Putative coding regions that included a signal peptide were extracted using a custom Perl script and analyzed following two different homology search strategies, namely sequence similarity searches using the BLASTP tool of the NCBI BLAST v2.6.0 package (Altschul 1997; Johnson et al. 2013; Martinson et al. Specifically, the three species share a similar toxin profile with C-type lectins, peptidases, metalloproteinases, spider toxins, and CAP proteins found among the most highly expressed toxin homologs. Metalloproteinase-like transcripts are among the most diverse putative fireworm toxins identified, with 36 transcripts distributed in 7 orthologous clusters representing both the astacin (M12a) and reprolysin (M12b) subfamilies. Transcriptomes for E. complanata and P. jeffreysii were generated as described in Weigert et al. Pie charts show the diversity of toxin homologs identified in each transcriptome. Animal venoms, primarily defined as toxic biological secretions produced by one animal and delivered to another through the infliction of a wound, have originated independently in numerous lineages as adaptations for defense, predation, and intraspecific competition (Fry et al. Harian Metro reported that Mohd Fadzil Mohd Yunus who is from Kampung Durian Hijau, Terachi was stung by a golden fireworm […] This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (, The first draft genome of a cold-water coral, Whole Genome Sequencing of Procyonids Reveals Distinct Demographic Histories in Kinkajou (, The Location of Substitutions and Bacterial Genome Arrangements, Polygenic selection within a single generation leads to subtle divergence among ecological niches, Volume 12, Issue 12, December 2020 (In Progress), About the Society for Molecular Biology and Evolution, Evidence of the Venomous Nature of Fireworms, http://dx.doi.org/10.1016/j.toxicon.2015.09.002, http://dx.doi.org/10.1016/S0965-1748(03)00116-4, http://dx.doi.org/10.1093/bioinformatics/btu170, http://dx.doi.org/10.1016/0197-0186(85)90009-9, http://dx.doi.org/10.1016/j.cbpc.2017.04.007, http://dx.doi.org/10.1016/j.ibmb.2013.03.010, http://dx.doi.org/10.1093/bioinformatics/btr088, http://dx.doi.org/10.1016/j.toxicon.2015.09.004, http://dx.doi.org/10.1007/s00018-015-2016-x, http://dx.doi.org/10.1016/0041-0101(85)90160-6, http://dx.doi.org/10.1074/mcp.M700094-MCP200, http://dx.doi.org/10.1146/annurev.genom.9.081307.164356, http://dx.doi.org/10.1007/s00239-009-9223-8, http://dx.doi.org/10.1016/0041-0101(95)00079-2, http://dx.doi.org/10.1016/j.toxicon.2014.10.003, http://dx.doi.org/10.1016/S0020-7519(03)00163-2, http://dx.doi.org/10.1016/j.peptides.2011.09.022, http://dx.doi.org/10.1016/j.toxicon.2004.10.018, http://dx.doi.org/10.1016/j.toxicon.2012.03.010, http://dx.doi.org/10.1016/j.meegid.2009.10.012, http://dx.doi.org/10.1093/bioinformatics/bts199, http://dx.doi.org/10.1016/j.toxicon.2013.09.017, http://dx.doi.org/10.1016/S0091-6749(96)70093-3, http://dx.doi.org/10.1016/j.toxicon.2003.11.002, http://dx.doi.org/10.1016/0378-1119(91)90155-5, http://dx.doi.org/10.1016/j.neuropharm.2007.03.012, http://dx.doi.org/10.1146/annurev.bi.49.070180.003113, http://dx.doi.org/10.1186/gb-2006-7-5-216, http://dx.doi.org/10.1016/j.biochi.2011.03.001, http://dx.doi.org/10.1016/j.biochi.2012.07.007, http://dx.doi.org/10.1016/0305-0491(75)90294-1, http://dx.doi.org/10.1007/s10126-012-9491-y, http://dx.doi.org/10.1016/j.toxicon.2005.02.021, http://dx.doi.org/10.1111/j.1365-4632.2011.05431.x, http://dx.doi.org/10.1186/s12862-017-0904-4, http://dx.doi.org/10.1016/j.dci.2009.12.004, http://dx.doi.org/10.1111/j.1463-6409.1997.tb00412.x, http://dx.doi.org/10.1007/s00239-013-9552-5, http://dx.doi.org/10.1016/j.ibmb.2007.04.004, http://dx.doi.org/10.1007/s00049-012-0112-z, http://dx.doi.org/10.1046/j.1529-8019.2002.01505.x, http://dx.doi.org/10.1093/bioinformatics/btl446, http://dx.doi.org/10.1093/bioinformatics/btu033, http://dx.doi.org/10.1890/1540-9295-13.4.226, http://dx.doi.org/10.1016/j.jprot.2014.01.013, http://dx.doi.org/10.1016/j.str.2015.05.003, http://dx.doi.org/10.1074/mcp.M116.063321, http://dx.doi.org/10.1016/j.biochi.2011.12.008, http://dx.doi.org/10.1007/s00239-005-0010-x, http://dx.doi.org/10.1007/s13127-016-0265-7, http://dx.doi.org/10.1074/mcp.M112.017491, http://dx.doi.org/10.1016/j.toxicon.2013.10.006, http://dx.doi.org/10.1016/j.toxicon.2004.05.023, http://dx.doi.org/10.1093/bioinformatics/17.9.847, http://creativecommons.org/licenses/by-nc/4.0/, Receive exclusive offers and updates from Oxford Academic, Copyright © 2020 Society for Molecular Biology and Evolution.
