Acute hepatotoxicity of Crotalus durissus terrificus (South American rattlesnake) venom in rats J. Venom. Anim. Toxins incl. Trop. Dis.
França,RF; Vieira,RP; Ferrari,EF; Souza,RA; Osorio,RAL; Prianti-Jr,ACG; Hyslop,S; Zamuner,SR; Cogo,JC; Ribeiro,W.
Venom of the South American rattlesnake, Crotalus durissus terrificus (Cdt), presents myotoxic and neurotoxic outcomes, but reports on its effects on the liver are scarce. This study examined the hepatotoxicity resulting from Cdt venom administration (100, 200 and 300 µg/kg) in male Wistar rats. Animals were studies at 3, 6, 9 and 12 hours after venom injection. The hepatotoxicity was assessed through serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (AP), gamma glutamyl transferase (GGT), bilirrubin and also by histopathological evaluation. All the different concentrations of Cdt venom resulted in increased levels of hepatic enzymes, when compared with the control group, except for the 100 µg/kg dose,...

American rattlesnake (Crotalus durissus terrificus) bite accidents in dogs in Argentina Arq. Bras. Med. Vet. Zootec.
Koscinczuk,P.; Acosta de Pérez,O.; Teibler,P.; Maruñak,S.; Rosciani,A.S..
The symptomatology and treatment of two dogs bitten by Crotalus durissus terrificus are described. Neurological signs were present few minutes after the accident with local anesthesia and ataxia of the affected limb and neurotoxic fascia. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine kinase (CK), lactate dehydrogenase (LDH) and calcium were evaluated in an attempt to investigate muscle damage. Renal failure was not observed but some alterations were detected in urine. Urine density was low and the urinary sediment contained granular clumps and small round cells. Muscle samples were obtained from both legs for histopathological study, showing edema and isolated necrotic fibers. Both dogs received treatment within four hours...

Biochemical comparison of venoms from young Colombian Crotalus durissus cumanensis and their parents J. Venom. Anim. Toxins incl. Trop. Dis.
Céspedes,N; Castro,F; Jiménez,E; Montealegre,L; Castellanos,A; Cañas,CA; Arévalo-Herrera,M; Herrera,S.
Crotalus durissus cumanensis, a rattlesnake endemic to Colombia and Venezuela, is considered one of the most lethal snake species in Latin America. The aim of the present study was to compare the protein content and biological activity of the venom obtained from eight specimens of C. durissus cumanensis, namely two adults from different localities of Colombia and six offspring born in captivity. Protein profiles of crude venoms were analyzed by SDS-PAGE and RP-HPLC, and biological activities were evaluated for lethality, edema, defibrination, hemolytic and coagulant activities to assess individual venoms of adults and a pool of young snake venoms. Transient edema appeared rapidly after venom inoculation, whereas hemorrhagic effect was not observed....

Bordonein-L, a new L-amino acid oxidase from Crotalus durissus terrificus snake venom: isolation, preliminary characterization and enzyme stability J. Venom. Anim. Toxins incl. Trop. Dis.
Bordon,Karla C. F.; Wiezel,Gisele A.; Cabral,Hamilton; Arantes,Eliane C..
BackgroundCrotalus durissus terrificus venom (CdtV) is one of the most studied snake venoms in Brazil. Despite presenting several well known proteins, its L-amino acid oxidase (LAAO) has not been studied previously. This study aimed to isolate, characterize and evaluate the enzyme stability of bordonein-L, an LAAO from CdtV.Methods The enzyme was isolated through cation exchange, gel filtration and affinity chromatography, followed by a reversed-phase fast protein liquid chromatography to confirm its purity. Subsequently, its N-terminal amino acid sequence was determined by Edman degradation. The enzyme activity and stability were evaluated by a microplate colorimetric assay and the molecular mass was estimated by SDS-PAGE using periodic acid-Schiff...

Crotamine in Crotalus durissus: distribution according to subspecies and geographic origin, in captivity or nature J. Venom. Anim. Toxins incl. Trop. Dis.
Tasima,Lídia J.; Serino-Silva,Caroline; Hatakeyama,Daniela M.; Nishiduka,Erika S.; Tashima,Alexandre K.; Sant’Anna,Sávio S.; Grego,Kathleen F.; Morais-Zani,Karen de; Tanaka-Azevedo,Anita M..
Abstract Background: Crotalus durissus is considered one of the most important species of venomous snakes in Brazil, due to the high mortality of its snakebites. The venom of Crotalus durissus contains four main toxins: crotoxin, convulxin, gyroxin and crotamine. Venoms can vary in their crotamine content, being crotamine-negative or -positive. This heterogeneity is of great importance for producing antivenom, due to their different mechanisms of action. The possibility that antivenom produced by Butantan Institute might have a different immunorecognition capacity between crotamine-negative and crotamine-positive C. durissus venoms instigated us to investigate the differences between these two venom groups. Methods: The presence of crotamine was analyzed...

Is the population of Crotalus durissus (Serpentes, Viperidae) expanding in Brazil? J. Venom. Anim. Toxins incl. Trop. Dis.
Duarte,Marcelo Ribeiro; Menezes,Frederico Alcântara.
Crotalus durissus are found from Mexico to northern Argentina in a highly disjunct distribution. According to some studies, this species is prone to occupy areas disturbed by human activities and floods comprise a plausible method of dispersal as inferred for some North American rattlesnakes. Based on the literature, it seems plausible that Crotalus durissus expanded their natural distribution in Brazil due to floods, but only in a few municipalities in Rio de Janeiro State. Data entries of Butantan Institute, in São Paulo, Brazil, from 1998 to 2012 show a declining tendency of snakes brought by donors. In addition, research shows no evidence of Crotalus durissus being an expanding species in the Brazilian territory.

Ophidascaris durissus sp. nov. (Nematoda Ascarididae) parasitizing Crotalus durissus Linnaeus (Ophidia, Viperidae) in Brazil Zoologia
Panizzutti,Marcia Helena Martins; Santos,Leonilda Correia dos; Vicente,Joaquim Júlio; Muniz-Pereira,Luís Cláudio; Pinto,Roberto Magalhães.
The species Ophidascaris durissus sp. nov. is proposed with basis on specimens recovered from the rattlesnake Crotalus durissus L., 1758 (type host) captured in Foz do Iguaçu, Brazil (type locality). By the lack of interlabia, the new species can be compared only to O. natricis Yamaguti, 1935 from Japan and O. freitasi Hoa & Lien, 1970, from Vietnam. However, O. durissus sp. nov. differs from O. natricis mainly by the absence of internal lip papillae, location of the vulvar aperture and length of the spicules; from O. freitasi mostly by the greater number of pre-cloacal and distribution of post-cloacal papillae.

Random amplified polymorphisms between two South American subspecies of rattlesnakes (Crotalus durissus collilineatus and Crotalus durissus terrificus) BABT
Echeverrigaray,Sergio; Grazziotin,Gilberto; Grazziotin,Felipe; Agostini,Gustavo.
The present work was made to determine the suitability of RAPD analysis for the identification of specimens of two subspecies of South American rattlesnakes (Crotalus durissus terrificus and Crotalus durissus collilineatus). The 11 arbitrary primer sequence tested amplified a total of 161 bands, of which 31% were polymorphics when compared with Crotalus specimens. The combining results from different primers allowed the identification of all the specimens under analysis. Several characteristic bands of each subspecies were identified. Dendrogram, based on RAPD markers, show three groups that corresponded to the subspecies of Crotalus, and to Bothrops jararaca specimen.

Records of the rattlesnakes Crotalus durissus terrificus (Laurenti) (Serpentes, Viperidae) in the State of Rio de Janeiro, Brazil: a possible case of invasion facilitated by deforestation Zoologia
Bastos,Eduardo G. de M.; Araújo,Alexandre F. B. de; Silva,Hélio R. da.
This paper documents the presence of rattlesnakes, as an invasive species, in several municipalities of the State of Rio de Janeiro. As previous registers indicate, these snakes probably invaded at least the municipality of Valença carried by floodwaters between the decades of 1950 and 1960. In the new environment, along the margins of the Rio Preto, these snakes were able to establish new populations in deforested areas turned into cattle grazing. The presence of rattlesnake in the municipality of Barra do Piraí, a municipality that has no border with Rio Preto, however, indicates that these snakes dispersal into new areas may be facilitated by open areas, represented by pastures, created after deforestations.
