[PMID: 39076609 PMCID: PMC11262277 DOI: 10.1016/j.soh.2023.100013] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Accepted: 02/28/2023] [Indexed: 07/31/2024]
Abstract
Background The One Health concept considers the interconnectivity, interactions and interdependence of humans, animals and the environment. Humans, animals and other organisms are constantly exposed to a wide range of natural toxins present in the environment. Thus, there is growing concern about the potential detrimental effects that natural toxins could pose to achieve One Health. Interestingly, alkaloids, steroids and bioactive peptides obtained from natural toxins could be used for the development of therapeutic agents. Methodology Our literature search focused on the following keywords; toxins, One Health, microbial toxins, mycotoxins, phytotoxins, phycotoxins, insect toxins and toxin effects. Google Scholar, Science Direct, PubMed and Web of Science were the search engines used to obtain primary databases. We chose relevant full-text articles and review papers published in English language only. The research was done between July 2022 and January 2023. Results Natural toxins are poisonous substances comprising bioactive compounds produced by microorganisms, invertebrates, plants and animals. These compounds possess diverse structures and differ in biological function and toxicity, posing risks to human and animal health through the contamination of the environment, causing disease or death in certain cases. Findings from the articles reviewed revealed that effects of natural toxins on animals and humans gained more attention than the impact of natural toxins on the environment and lower organisms, irrespective of the significant roles that lower organisms play to maintain ecosystem balance. Also, systematic approaches for toxin control in the environment and utilization for beneficial purposes are inadequate in many regions. Remarkably, bioactive compounds present in natural toxins have potential for the development of therapeutic agents. These findings suggest that global, comprehensive and coordinated efforts are required for improved management of natural toxins through an interdisciplinary, One Health approach. Conclusion Adopting a One Health approach is critical to addressing the effects of natural toxins on the health of humans, animals and the environment.

Abstract
OBJECTIVE The purpose of this study is to demonstrate that hyperbaric oxygen therapy (HBOT) is an option for the management of rapidly progressive tissue necrosis after centipede bites in patients with diabetes. METHOD In this case report, we introduce a patient with diabetes with soft tissue necrosis and secondary infection due to a centipede bite, who was treated with a multidisciplinary approach including HBOT. RESULTS In this case study, HBOT, applied in the treatment of rapidly developing cellulitis after a centipede bite in a patient with diabetes, accelerated wound healing. Deep soft tissue infection stopped progression to necrotising fasciitis and prevented possible amputation, and facilitated the patient's return to social life in a short time. CONCLUSION HBOT can be used in combination with other local and systemic, due to its anti-venom effect and treatment of extremity-threatening infection.

Isolation and characterization of the major centipede allergen Sco m 5 from Scolopendra subspinipes mutilans. Allergol Int 2021; 70:121-128. [PMID: 32680616 DOI: 10.1016/j.alit.2020.06.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2019] [Revised: 06/02/2020] [Accepted: 06/05/2020] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND Allergic reactions have been observed following both direct centipede bites and the clinical use of centipede-containing medicines, such as traditional Chinese medicines utilizing Scolopendra subspinipes mutilans; however, no natural centipede allergen has yet been characterized. METHODS An allergen was purified from S. s. mutilans venom using Superdex 75 gel filtration and RESOURCE S ion chromatography, and its primary structure was determined via a combination of LC-MS-MS, MALDI-TOF/TOF and protein sequencing techniques. Its potential allergenicity was evaluated by immunoblotting, ELISAs, skin prick tests (SPTs) and mast cell activation assays. RESULTS A novel allergen Sco m 5 (210 amino acids long) was successfully purified from crude S. s. mutilans venom. Sco m 5 could promote the degranulation of a human mast cell line, HMC-1. Among centipede-allergic patients, Sco m 5 showed an 83.3% IgE-binding frequency and a 66.7% positive reaction frequency, as detected by immunoblotting and SPTs, respectively. Sco m 5 IgE-binding frequencies of common Chinese population was found to be 9%-16%. Sera positive for Sco m 5 IgE-binding was cross-reactive against venom from the wasp Vespa mandaeinia. CONCLUSIONS The present study isolated and characterized a novel allergen termed as Sco m 5 from the centipede S. s. mutilans. The use of Sco m 5 to identify centipede-allergic individuals could be important, given the high potential allergenicity of Sco m 5 among the general Chinese population, along with the likely possibility of cross-reactivity against wasp venom among centipede-allergic patients.

Abstract
Background: Scolopendrae represent the best-known genus of centipedes. They are nocturnal general feeders with strong mandibles and venomous fangs which leave visible puncture marks at the bite site. The bite accidents occur during the warm rainy season and mostly take place on the extremities. Following the bite, the most common symptoms are mild: limited localized erythema, pain, swelling, local itching and burning sensation. However, more severe local and systemic sequelae can not be excluded. Method: we report the case of a 63-year-old man with fever and a widespread edema of the right hand and forearm, happened as a consequence of a Scolopendra Subspinipes bite. During the weeks following the bite, he developed a severe unusual superinfection via hematogenous dissemination, which required a double surgical debridement and a targeted intravenous antibiotic therapy. Results: the complete clinical recovery took over two months. Conclusions: Many victims of Scolopendra envenomation do not seek medical attention since most symptoms will resolve spontaneously. The case presented falls within the spectrum of those rare cases which escalate due to bacterial superinfection.

An evidence based efficacy and safety assessment of the ethnobiologicals against poisonous and non-poisonous bites used by the tribals of three westernmost districts of West Bengal, India: Anti-phospholipase A2 and genotoxic effects. PLoS One 2020; 15:e0242944. [PMID: 33253320 PMCID: PMC7703885 DOI: 10.1371/journal.pone.0242944] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2020] [Accepted: 11/12/2020] [Indexed: 12/29/2022] Open
Abstract
Introduction To explore the ethnobiological wisdom of the tribals of three western districts of West Bengal, India against poisonous and non-poisonous bites and stings, a quantitative approach was adopted. These age-old yet unexplored knowledge can be utilized in finding lead-molecules against poisonous and non-poisonous animal-bites. Further, an evidence-based approach is needed to assess the venom-neutralization ability of plants by experimental studies. Materials and methods During 2008–2009 and 2012–2017, 11 ethnomedicinal surveys were carried out to explore the use of medicinal flora and fauna via conducting open semi-structured interviews with 47 traditional healers (THs) or informants. The retrieved dataset was statistically evaluated using seven quantitative-indexes: use-value (UV), informants'-consensus-factor (ICF), fidelity-level (FL), relative-importance (RI), cultural importance-index (CI), index of agreement on remedies (IAR) and cultural agreement-index (CAI). Anti-phospholipaseA2 (PLA2) properties of selected plant extracts were also examined. In addition, the cytotoxicity and genotoxicity of the water extract of the plants showing high FL as well as significant PLA2 inhibitory potential were investigated using Allium cepa root tip assay. Results A total of 41 traditional-formulations (TFs) containing 40 plant species (of 39 genera from 28 families) and 3 animal species were prescribed by the THs. Fabaceae exhibited most number of medicinal plants. Piper nigrum (1.78) and Apis cerana indica and Crossopriza lyoni (both 0.21) exhibited the highest UV among the plants and the animals respectively. Stinging of centipede and dog/cat/hyena bite displayed highest ICF (1.00 each). Among the plants, the maximum RI (0.91) and CI (4.98) values were observed for Aristolochia indica. IAR (1.00) was recorded maximum for Achyranthes aspera, Gloriosa superba, Lycopodium cernuum, Smilax zeylanica and Streblus asper. Maximum CAI value was noted for Piper nigrum (5.5096). Among the animals, Apis cerana indica (0.31) and Crossopriza lyoni (1.52) displayed the highest RI and CI values respectively. Crossopriza lyoni (0.99) and Apis cerana indica (1.3871) exhibited maximum IAR and CAI values respectively. Plants showing higher FL exhibited higher anti-PLA2 activity via selective inhibition of human-group PLA2. In addition, Allium cepa root tip assay has indicated the safety and/or toxicity of the plant parts prescribed by the THs. Root water extracts of Aristolochia indica and Gloriosa superba exhibited significant genotoxicity and cytotoxicity. Conclusions Three western districts of West Bengal is the natural abode for many tribal and non-tribal communities. A noteworthy correlation was established between the plants used against poisonous-bites and their anti-PLA2 activity. A few plant parts used by the THs also exhibited high toxicity. Such alternative medical practices serve as the only option in these underprivileged and backward areas during medical-exigencies.

[PMID: 30717088 PMCID: PMC6409716 DOI: 10.3390/toxins11020076] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2018] [Revised: 01/25/2019] [Accepted: 01/27/2019] [Indexed: 12/19/2022] Open
Abstract
It was recently discovered that Ssm Spooky Toxin (SsTx) with 53 residues serves as a key killer factor in red-headed centipede’s venom arsenal, due to its potent blockage of the widely expressed KCNQ channels to simultaneously and efficiently disrupt cardiovascular, respiratory, muscular, and nervous systems, suggesting that SsTx is a basic compound for centipedes’ defense and predation. Here, we show that SsTx also inhibits KV1.3 channel, which would amplify the broad-spectrum disruptive effect of blocking KV7 channels. Interestingly, residue R12 in SsTx extends into the selectivity filter to block KV7.4, however, residue K11 in SsTx replaces this ploy when toxin binds on KV1.3. Both SsTx and its mutant SsTx_R12A inhibit cytokines production in T cells without affecting the level of KV1.3 expression. The results further suggest that SsTx is a key molecule for defense and predation in the centipedes’ venoms and it evolves efficient strategy to disturb multiple physiological targets.
