An overview of Bothrops erythromelas venom

Abstract This review discusses studies on the venom of Bothrops erythromelas published over the past 36 years. During this period, many contributions have been made to understand the venomous snake, its venom, and its experimental and clinical effects better. The following chronological overview is based on 29 articles that were published between 1979 and 2015, with emphasis on diverse areas. The complexity of this task demands an integration of multidisciplinary research tools to study toxinology. This science is in need of renewed conceptual and experimental platforms aimed at obtaining a profound understanding of the highly complex pathophysiology of snakebite envenoming and toxins isolated from snakes.

Humoral immune response of patients bitten by the snake Bothrops erythromelas / Resposta imune humoral em pacientes picados pela serpente Bothrops erythromelas

INTRODUCTION: Snake envenomings are a health problem in rural areas of tropical and subtropical countries, but little is known regarding the immune response presented by bitten individuals. The IgM production of patients bitten by Bothrops erythromelas snake was analyzed to identify the effectiveness of treatment in this type of envenomation. METHODS: Bothrops erythromelas venom was submitted to electrophoresis and transferred to a nitrocellulose sheet, following incubation with patients' sera. RESULTS: A 38 KDa protein was detected before and 24 h after therapy. CONCLUSIONS: The result suggests that this protein could be used as a marker for individuals envenomed by Bothrops. erythromelas.

INTRODUÇÃO: Envenenamentos ofídicos consistem problema de saúde pública em áreas rurais de países tropicais e subtropicais, mas pouco sabe-se sobre a resposta imune apresentada pelos indivíduos picados, por isso a avaliação da produção de IgM por pacientes picados por Bothrops erythromelas identificando a eficácia do tratamento nesse tipo de envenenamento. MÉTODOS: O veneno de Bothrops erythromelas foi submetido a eletroforese e transferido para nitrocelulose, seguindo incubação com soro de pacientes. RESULTADOS: Foi observada proteína de 38KDa antes e 24 horas após o tratamento. CONCLUSÕES: Os resultados sugerem que essa proteína poderia ser utilizada como marcador para indivíduos envenenados pela serpente Bothrops erythromelas.
