Since we were diving alone, we were going very slowly and I came upon this fireworm. Their suggestion is to take some adhesive tape (probably not duck tape :)) and put it over the affected area. 2017), remipede crustaceans (von Reumont et al. 2014c). 2013; Moran et al. 2014; von Reumont et al. Following these criteria, our findings provide strong evidence supporting that fireworms are venomous organisms that endogenously produce a proteinaceous mixture of peptide toxins and venom protein homologs. S6, Supplementary Material online). 2013; Bose et al. 2004; Savitzky et al. 2014, 2016; von Reumont et al. Conserved residues are colored, including the conserved cysteines, which are highlighted in yellow. 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. A facial "peel" may be used over the over the spines or a thick layer of rubber cement. When touched, they break off on the surface of the skin and irritate it via a neurotoxin. Wash with soap and fresh water. 1985; von Reumont et al. 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). An allergic reaction to fireworm venom is always a possibility. 2015; Weigert and Bleidorn 2016). 2014b; Kvist et al. Part I: the invertebrates, Identification, cloning, and recombinant expression of procalin, a major triatomine allergen, Serine peptidases: classification, structure and function. Transcriptomes for E. complanata and P. jeffreysii were generated as described in Weigert et al. 2009; Huang et al. All trees where rooted with nonvenomous homologs. Bearded fireworm (Busuf), Hermodice carunculata. They'll help protect against minor jelly stings and sea lice. Following this pipeline, we identified 34 clusters of orthologous genes, representing 13 known toxin classes that have been repeatedly recruited into animal venoms. After RNA extraction and sequencing, the first step is data processing (green) and de novo assembly of the transcriptomes. This first of two articles will review the well-known jellyfish stings and other less familiar venomous organisms such as the bristle worm and the sting ray. 2013, 2014, 2016; Amorim 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. 2009; von Reumont et al. Harian Metro reported that Mohd Fadzil Mohd Yunus, who comes from Kampung Durian Hijau, Terachi was working as a tourist guide on the island when the incident occurred in December 2017. The deep structure of the kunitz-type protease inhibitor phylogeny is poorly supported and does not reveal a clear evolutionary pattern (supplementary fig. 2017). Tree reconstructed with RAxML-HPC-PTTHREADS v8.2.10 and support values estimated through a rapid bootstrap algorithm and 1,000 pseudoreplicates. http://en.wikipedia.org/wiki/Bearded_fireworm. —Phylogenetic tree of lipocalin sequences. —Phylogeny of the family Amphinomidae and venomous annelid representatives. 2003; Xu et al. 2014b) (fig. 7). Remainder images (F and D) are publicly available under Creative Commons License. Handling a fireworm is a memorable experience. 2016). 2014b). Gustafson (1930) attributed the toxicity of fireworms to a clear gelatinous substance filling the chaetal core, while Schulze et al. CAP proteins have been recruited into the venoms of many taxa including reptiles, bats, monotremes, cnidarians, mollusks, crustaceans, spiders, scorpions, nemerteans, and bloodworms (Fry et al. 2016). 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. 2006). Venom phospholipases can induce necrosis, inflammation, inhibition of blood coagulation, and blocking of the neuromuscular transmission (Kini 2003; Fry et al. Some of the fireworms, called bearded fireworms, are lined with fine white hairs. Photo: West Brom 4ever, via Wikimedia Commons The predicted signal sequence is delimited by a yellow square and the Kazal domain is delineated by a purple square. Several of the fireworm phospholipases cluster with Glycera bloodworm sequences whereas others form a clade more closely related with snake phospholipases (supplementary fig. Bootstrap support values are given for all nodes and clade names are indicated by colored squares. 2006) (fig. 7). 2014b;Modica et al. Due to the lack of a reference genome, the processed reads were de novo assembled using Trinity v2.4.0 (Grabherr et al. ( Log Out /  2014b) and arthropods including remipede crustaceans, caterpillars, parasitoid wasps, and blood feeding insects like ticks and mosquitoes (Veiga et al. 2012). One of the first hints you’re dealing with a fireworm is that you actually see it. 2017). Ointment. About 10 out of the 12 toxins group in one clade in the serpin tree whereas the remaining two are clustered in another clade that includes human, crustacean, and parasitoid wasp serpins (supplementary fig. 2012; von Reumont et al. 2013; Poirié et al. 2015; Phuong et al. 2012). Kazal-type inhibitor phylogeny including sequences from venomous and nonvenomous taxa and fireworm homologs. It has long been hypothesized that amphinomids are venomous and use the chaetae to inject a toxic substance. You may contact him via his website at http://www.drcharleshecht.com/contact-us/. Transcripts were searched using the BLASTP tool (Altschul 1997; Johnson et al. We would like to express our gratitude to David Gruber, John Sparks, Michael Lombardi, and Shaadi Mehr for sample collection and facilitating previously published data of Hermodice carunculata. 2012; Tsujimoto et al. In route, hold the bite site below the rest of the body, —Diversity of toxin homologs identified in each fireworm species. 2007; Kuhn-Nentwig et al. 2008) and with HMMER v3.1b2 (Eddy 2009; Finn et al. All putative fireworm lipocalins except one, cluster in a single clade (albeit not supported) that includes Lopap, a lipocalin from the Lonomia obliqua caterpillar venom that contributes to hemorrhagic syndrome through prothrombin activation (fig. 6) (Reis et al. 2012) and additional putative toxins identified by the Holford group. 2017). 1991; Kita et al. 2007; Kim et al. Kaas Q, Yu R, Jin AH, Dutertre S, Craik DJ. Kazal-type inhibitors act on a variety of serine proteases including thrombin, trypsin, factor XIIa, subtilisin A, elastase, chymotrypsin, and plasmin (Sigle and Ramalho-Ortigão 2013) and have been reported from the venoms of snakes and bats (Francischetti et al. The calcareous chaetae have been hypothesized to function as hypodermic needles that deliver an active toxin, which was identified as a trimethylammonium compound that causes strong skin irritation from the species Eurythoe complanata, and was consequently named Complanine (Nakamura et al. We are thankful to Anne Weigert and Torsten Struck for sharing transcriptome data for E. complanata and P. jeffreysii before it was publicly available. 2013; von Reumont et al. We have identified 11 CAP homologs that belong to 2 orthologous clusters among the fireworm putative toxins. However, there is a small chance that a more dangerous species (the fire worm) made its way into your tank. Lipocalin phylogeny including sequences from venomous and nonvenomous taxa and fireworm homologs. 2011) and used for phylogenetic tree reconstruction in RAxML-HPC-PTTHREADS v8.2.10 (Stamatakis 2006, 2014) with support values estimated through a rapid bootstrap algorithm and 1,000 pseudoreplicates. A cross section of the posterior end of the animal was dissected for total RNA extraction. Diving for the more than six years now, I have learned not to touch anything with the name fire in it (or pay a dire consequence). Hits with an e-value of 1e-5 or less derived from each independent search (BLASTP, HMMER sequence, HMMER domain) were considered putative toxins and, after removing redundant sequences, searched against the UniProtKB/Swiss-Prot nonredundant protein sequence database using BLASTP (Altschul 1997; Johnson et al. 2012; Wong et al. We identified 34 clusters of orthologous genes that represent 13 distinct toxin classes that have been convergently recruited into a wide array of animal venoms (fig. 1A–C). Dracunculiasis, also called Guinea-worm disease (GWD), is a parasitic infection by the Guinea worm. The kind of bristle worm that you really need to focus on keeping away from your aquarium fish is the “fireworm” family. 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. 2007; Choo et al. In addition to the predatory use of venom, there are also annelids that utilize toxins as a defensive mechanism (fig. 1A–D). 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. 2004; Whittington et al. 2008; Ottuso 2013; Haddad 2015; Schulze et al. 2015), leeches, and bloodworms (Kvist et al. Carrying poison in their feet is a successful defense for fireworms. 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. We have also identified a variety of spider toxin-like genes in the fireworm transcriptomes, including homologs of agatoxin, atracotoxin, ctenitoxin, hainantoxin, and latrotoxin. 2013; Sunagar et al. Annelids are a promising and often neglected group for venomics research. 2017). First, It has been shown that gene models predicted to encode toxin-like proteins by similarity searches matched known venom components more likely if they are overexpressed in the venom gland and if their best BLAST hit is a known venom protein (as opposed to another protein from the UniProtKB database) (Rodríguez De La Vega and Giraud 2016). 2014; Modica et al. I had a neon goby start looking sick and die over the course of 4 days. Sequences from nonvenomous taxa are indicated with closed circles and fireworm homologs are highlighted in bold. 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. 2013), parasitoid wasps (Perkin et al. Cover the area with vinegar to neutralise the sting as soon as possible but if it is still causing irritation seek medical advice. How Bad Is A Bearded Fireworm Sting? Get some tape stick, it over the area and peel it off. Bon C, Saliou B, Thieffry M, Manaranche R. Borda E, Kudenov JD, Bienhold C, Rouse GW. 2013; von Reumont et al.

In the case of a sting from highly toxic Zebrafish/Lionfish, Scorpionfish or Stonefish. The final databases of candidate toxins for each species were manually curated and orthologous clusters of putative toxins shared by the three species were identified and annotated with OrthoVenn (Wang et al. 2013) was first used to predict protein-coding regions within transcripts. A recent transcriptomic study found a similar profile of toxins expressed in the venom gland of the bloodworm Glycera dibranchiata (Annelida, Glyceridae) with peptidase S1 being the most abundant class in this species, and metalloproteinase M12, C-type lectin, and CAP found among the most abundantly expressed toxins, adding up to roughly 60% of the overall toxin precursors identified (von Reumont et al. 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.

They have been identified from a variety of animal venoms including snakes and frogs (Calvete et al. 2015; Siddall et al. 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. 2013; Sigle and Ramalho-Ortigão 2013; Negulescu et al. 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). Change ), You are commenting using your Twitter account. Rubbing alcohol/ isopropyl alcohol or vinegar may help to alleviate the painful burning sensation caused by a bearded fireworm sting. 2014b;Whelan et al. Kunitz-type inhibitors are ubiquitous serine protease inhibitors of approximately 60 amino acids with three conserved disulfide bridges that show inhibitory activity against trypsin, chymotrypsin, or both (Laskowski and Kato 1980; Wan et al.

Cystatin phylogeny including sequences from venomous and nonvenomous taxa and fireworm homologs. A jellyfish can sting you even if it's dead. The Bristles You Must Banish - Fireworm Identification Tip. 2016) while glycerid bloodworms use a mixture of toxins to capture and immobilize prey (von Reumont et al. Our venomics pipeline involved de novo transcriptome assembly, open reading frame, and signal sequence prediction, followed by three different homology search strategies: BLAST, HMMER sequence, and HMMER domain. 2012; von Reumont et al. Although differences in toxin composition are commonly found among different species (Colinet et al.

Even lemon juice, vinegar, and kalkwasser paste are a common, cheap, and effective way to kill them. Conversely, Schulze et al. 2015). Kenny, our proprietor at the hotel, asked me if I touched him with a grin. When pulling it from the skin, it will also grab and pull the bristles from the skin and stop further irritation. Transcripts initially identified as putative toxins that did not meet these criteria were considered false positives and excluded from downstream analyses. So I have a 8 gal. These symptoms are consistent with the expression of the putative peptide toxins and venom proteins identified in this study. Their suggestion is to take some adhesive tape (probably not duck tape :)) and put it over the affected area. 2009). 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). Change ). Transcriptomes of P. jeffreysii and E. complanata were generated as described in Weigert et al. Turripeptide-like toxins have also been reported from the venom glands of Glycera bloodworms, box jellyfish, and zoanthids (von Reumont et al. Serpin homologs were also recovered among the putative fireworm toxins. Latarcins are antimicrobial and cytolytic peptides from the venom of the spider Lachesana tarabaevi that adopt an amphiphilic α-helical structure in contact with lipid membranes and show general cytotoxicity and hemolytic activity (Kozlov et al. 2017). 2017). 2005; Fry et al. The intense itching and the occasional reports of anaphylactic reactions can be explained by the activities of S10 peptidases and CAP proteins, which are major allergens in hymenopteran venoms. If you suddenly see a worm with bristles emerge during feeding time, the chances are high that it’s a fireworm. Seek medical treatment if … Sequences from nonvenomous taxa are indicated with closed circles and fireworm homologs are highlighted in bold. One orthologous cluster comprising 5 kunitz-domain sequences was recovered among the putative toxins identified in H. carunculata, E. complanata, and P. jeffreysii transcriptomes. These criteria include the specific molecular composition of the toxins, and how the toxins are produced. ShKT domain-containing transcripts are one of the most expressed toxins in the venom glands of the bloodworm Glycera dibranchiata (von Reumont et al.

The CAP protein superfamily includes cysteine-rich secretory proteins (CRISPs), antigen 5 (Ag5), and pathogenesis-related 1 proteins (Pr-1) (Gibbs et al. 2017; Yan et al. 2011; Menaldo et al. Additionally, most poisonous organisms such as puffer fish, poison dart frogs, or birds like the hooded pitohui, sequester the toxins from their diet or from symbiotic microorganisms (Dumbacher et al. (2017) concluded that the intrachaetal cavity is artificial and found no evidence of associated venom glands, which led them to suggest that the physiological reactions triggered by fireworm stings result from direct injuries rather than venom injection. The sting of a bristleworm is something none of us want to deal with, but it is one of the hazards of the reef aquarium hobby, and hobbyists should probably be aware of the first aid options. Bootstrap support values are given for all nodes and clade names are indicated by colored squares. and Sipunculus nudus) and a mollusk (Chiton olivaceus), recovering only 18 putative toxins in Chaetopterus sp. 2017), the giant triton snail (Bose et al. The fireworm CAP homologs cluster in a clade (although with no support) that includes the rest of the annelid sequences and a few arthropod sequences (supplementary fig. Inter- and intraspecific variation in venom composition have been documented as a result of diverse factors such as sex, ontogeny, diet, or geographical locality (Colinet et al. There are a few ways to eradicate them. 2008; Perkin et al. Kazal-type inhibitors are serine protease inhibitors characterized by the presence of one or more Kazal domains, 40–60 amino acid long domains with a conserved structure of six cysteine residues forming three disulfide bridges (Laskowski and Kato 1980; Rimphanitchayakit and Tassanakajon 2010). 2014b; Modica et al. Lipocalins have also been identified as major allergens inducing severe anaphylactic reactions in humans after hematophagous insect bites (Paddock et al.
