First report of an accident with the speckled forest pit viper (Bothriopsis taeniata) in Brazil

Abstract

ReSuMoRelatamos o primeiro caso de acidente por Bothriopsis taeniata no Brasil. A vítima, trabalhador rural com 43 anos de idade, foi picada pouco acima do calcanhar direito, apresentando quadro clínico compatível por envenenamento botrópico leve: discreto edema com hemorragia no local da picada e dor, embora com ausência de coagulopatia. Palavras-chaves:Bothriopsis taeniata. Acidente botrópico. Amazônia. ABSTRAcTThe first reported case of an accident with Bothriopsis taeniata in Brazil is described. The victim, a 43-year-old man, was bitten just above his right heel and presented a clinical condition compatible with mild Bothrops poisoning: local edema with hemorrhage at the bite site and pain, although without coagulopathy.

Snakebites as a largely neglected problem in the Brazilian Amazon: highlights of the epidemiological trends in the State of Amazonas

“…The community surveys were conducted with forest-dwelling Indians and rubber tappers (seringueiros) in the Juruá Valley, Acre (7) , and with inhabitants of 10 riverine communities in the municipality of Berry, Amazonas. The case reports were all from the State of Pará (13) (15) (16) .…”

“…The fi rst reported case of an incident involving Bothriopsis taeniata in Brazil was described in a 43-year-old man who presented with local edema with hemorrhaging at the bite site and pain, although without coagulopathy (13) . The second publication reports a case of hemorrhagic stroke due to bothropic envenomation associated with severe hypertension (15) .…”

Venom Composition of Neglected Bothropoid Snakes from the Amazon Rainforest: Ecological and Toxinological Implications

“…The toxin groups detected here match the composition of venoms from different species of Bothrops , suggesting that in human accidents with the species studied here, there will be potential local and systemic signs and symptoms related to coagulant activities and hemorrhagic and inflammatory effects [ 50 , 59 ]. Indeed, a single report of a human accident with B. taeniatus described that the patient developed a clinical picture compatible with mild envenomation by B. atrox with small bleeding at the bite site and edema just below the knee without development of coagulopathy [ 60 ]. Also, even when collected outside the Brazilian territory, the activities of the B. bilineatus and B. taeniatus venoms are dominated by high proteolytic action on thrombin, plasmin, kallikrein, and cathepsin C [ 61 ].…”

Caracterização estrutural e funcional da fosfolipase 'A IND. 2' BtTX-II, purificada do veneno da serpente Bothriopsis taeniata

“…Isto ocorre devido à semelhança da coloração de corpo, que imita as folhas e líquens do chão da floresta (Melgarejo, 2003). Tem sido reportado um caso autêntico de uma picada desta serpente conhecida também como jararaca estrela (Torrez et al, 2009) ou jararaca tigrina (Miranda-Silva, 2009) (Figura 1).…”
