“…Oxybelis , commonly known as the vine snake, is a genus of colubrid snakes mainly endemic to the Americas. Here, we review a case of 67-year-old male that was bitten on his arm by Oxybelis fulgidus in Brazil [ 57 ]. He came to the local hospital with bite-site bleeding and dizziness.…”

There are an estimated 5.4 million snakebite cases every year. People with snakebite envenoming suffer from severe complications, or even death. Although some review articles cover several topics of snakebite envenoming, a review of the cases regarding cerebral complications, especially rare syndromes, is lacking. Here, we overview 35 cases of snakebite by front-fanged snakes, including Bothrops, Daboia, Cerastes, Deinagkistrodon, Trimeresurus, and Crotalus in the Viperidae family; Bungarus and Naja in the Elapidae family, and Homoroselaps (rare cases) in the Lamprophiidae family. We also review three rare cases of snakebite by rear-fanged snakes, including Oxybelis and Leptodeira in the Colubridae family. In the cases of viper bites, most patients (17/24) were diagnosed with ischemic stroke and intracranial hemorrhage, leading to six deaths. We then discuss the potential underlying molecular mechanisms that cause these complications. In cases of elapid bites, neural, cardiac, and ophthalmic disorders are the main complications. Due to the small amount of venom injection and the inability to deep bite, all the rear-fanged snakebites did not develop any severe complications. To date, antivenom (AV) is the most effective therapy for snakebite envenoming. In the six cases of viper and elapid bites that did not receive AV, three cases (two by viper and one by elapid) resulted in death. This indicates that AV treatment is the key to survival after a venomous snakebite. Lastly, we also discuss several studies of therapeutic agents against snakebite-envenoming-induced complications, which could be potential adjuvants along with AV treatment. This article organizes the diagnosis of hemotoxic and neurotoxic envenoming, which may help ER doctors determine the treatment for unidentified snakebite.

Snakebite envenomation is a neglected tropical disease that affects millions of people around the world with a great impact on health and the economy. Unfortunately, public health programs do not include this kind of disease as a priority in their social programs. Cases of snakebite envenomations in the Neotropics are inaccurate due to inadequate disease management from medical records to the choice of treatments. Victims of snakebite envenomation are primarily found in impoverished agricultural areas where remote conditions limit the availability of antivenom. Antivenom serum is the only Food and Drug Administration-approved treatment used up to date. However, it has several disadvantages in terms of safety and effectiveness. This review provides a comprehensive insight dealing with the current epidemiological status of snakebites in the Neotropics and technologies employed in antivenom production. Also, modern biotechnological tools such as transcriptomic, proteomic, immunogenic, high-density peptide microarray and epitope mapping are highlighted for producing new-generation antivenom sera. These results allow us to propose strategic solutions in the Public Health Sector for managing this disease. Keywords: antivenom, biotechnology, neglected tropical disease, omics, recombinant antibody.

“…Pode ser encontrada em uma grande variedade de ambientes, que incluem fragmentos florestais urbanos, vegetação ripária, bordas florestais, floresta de pinheiro, plantações (LOVICH et al, 2010;FRAGA et al, 2012;RODRÍGUEZ-PÉREZ et al, 2019;ALMEIDA et al, 2020). Embora ocorra essa amplitude tipos de ambientes utilizados, incluindo espaços antrópicos, os acidentes com humanos são raramente reportados (SILVA et al, 2019). Contudo, devido ao seu padrão de coloração verde e a proximidade com áreas urbanas, pode ser eventualmente confundida com a Bothrops bilineatus e ser morta por essa razão (FERMIANO et al, 2018).…”

Relatamos neste trabalho uma observação de predação de Ramphocelus carbo (Pallas, 1764) por Oxybelis fulgidus (Daudin, 1803) na área rural da cidade de Espigão D'Oeste, estado de Rondônia, Brasil, no sudoeste da Amazônia brasileira. O local é um sítio particular, em uma plantação de Café (Coffea canephora). A O. fulgidus predou o Ramphocelus carbo numa altura de aproximademente 120 cm do solo. Este relato de comportamento é de interesse pois demonstra o hábito de serpentes arborícolas de caçar próximo a fontes de alimento de suas presas (Ramphocelus carbo), assim aumentando a probabilidade de encontrar presas como aves.
