Local tissue damage induced by BaP1, a metalloproteinase isolated from Bothrops asper (Terciopelo) snake venom 

Rucavado Romero, Alexandra; Lomonte, Bruno; Ovadia, Michael; Gutiérrez, José María (1995-12)
The pathogenesis of hemorrhage and other local effects induced by the metalloproteinase BaP1, isolated from Bothrops asper venom, was investigated using various in vivo and in vitro models. Upon intramuscular injection in ...

Isolation and characterization of four medium-size disintegrins from the venoms of Central American viperid snakes of the genera Atropoides, Bothrops, Cerrophidion and Crotalus 

Angulo Ugalde, Yamileth; Castro Godínez, Adriana; Lomonte, Bruno; Rucavado Romero, Alexandra; Fernández Ulate, Julián; Calvete Chornet, Juan José; Gutiérrez, José María (2014-12)
Four disintegrins were isolated from the venoms of the Central American viperid snakes Atropoides mexicanus (atropoimin), Bothrops asper (bothrasperin), Cerrophidion sasai (sasaimin), and Crotalus simus (simusmin). ...

Identification of residues critical for toxicity in Clostridium perfringens phospholipase C, the key toxin in gas gangrene 

Alape Girón, Alberto; Flores Díaz, Marietta; Guillouard, Isabelle; Naylor, Claire E.; Titball, Richard; Rucavado Romero, Alexandra; Lomonte, Bruno; Basak, Ajit K.; Gutiérrez, José María; Cole, Steward T.; Thelestam, Mónica (2000-08)
Clostridium perfringens phospholipase C (PLC), also called α-toxin, is the major virulence factor in the pathogenesis of gas gangrene. The toxic activities of genetically engineered α-toxin variants harboring single ...

Skeletal muscle necrosis and regeneration after injection of Thalassophryne nattereri (niquim) fish venom in mice 

Lopes Ferreira, Mónica; Núñez, Javier; Rucavado Romero, Alexandra; Farsky, Sandra H. P.; Lomonte, Bruno; Angulo Ugalde, Yamileth; Moura Da Silva, Ana M.; Gutiérrez, José María (2001-02)
Stings by Thalassophryne nattereri are responsible for envenomation of fishermen in north-eastern Brazil. Its venom induces prominent local tissue damage, characterized by pain, oedema and necrosis. The pathogenesis of ...

Proteomic and functional profiling of the venom of Bothrops ayerbei from Cauca, Colombia, reveals striking interspecific variation with Bothrops asper venom 

Mora Obando, Diana; Guerrero Vargas, Jimmy; Prieto Sánchez, Rodrigo; Beltrán, José; Rucavado Romero, Alexandra; Sasa Marín, Mahmood; Gutiérrez, José María; Ayerbe, Santiago; Lomonte, Bruno (Journal of Proteomics Volume 96, 16 January 2014, Pages 159–172, 2014-01)
Bothrops ayerbei, a pitviper inhabiting the Patía River's basin (Valle Alto del Río Patía) in the Southwestern Department of Cauca, Colombia, was considered as a variant form of Bothrops asper prior to being proposed as a ...

Tissue pathology induced by snake venoms: How to understand a complex pattern of alterations from a systems biology perspective? 

Gutiérrez, José María; Rucavado Romero, Alexandra; Escalante Muñoz, Teresa; Lomonte, Bruno; Angulo Ugalde, Yamileth; Fox, Jay W. (2010-01)
The study of snake venom-induced local tissue pathology has been predominantly based on experimental designs and concepts that view tissue alterations from a dichotomous, homogeneous and reductionist perspective. Experimental ...

Snake Venomics of the Lesser Antillean Pit Vipers Bothrops caribbaeus and Bothrops lanceolatus: Correlation with Toxicological Activities and Immunoreactivity of a Heterologous Antivenom 

Gutiérrez, José María; Sanz, Libia; Escolano, José; Fernández Ulate, Julián; Lomonte, Bruno; Angulo Ugalde, Yamileth; Rucavado Romero, Alexandra; Warrell, David A.; Calvete Chornet, Juan José (2008-10)
The venom proteomes of the snakes Bothrops caribbaeus and Bothrops lanceolatus, endemic to the Lesser Antillean islands of Saint Lucia and Martinique, respectively, were characterized by reversephase HPLC fractionation, ...

Trends in Snakebite Envenomation Therapy: Scientific, Technological and Public Health Considerations 

Gutiérrez, José María; Lomonte, Bruno; León Montero, Guillermo; Rucavado Romero, Alexandra; Chaves Mora, Fernando; Angulo Ugalde, Yamileth (2007)
The therapy of snakebite envenomation has been based on the parenteral administration of animal-derived antivenoms. Despite the success of this treatment at reducing the impact of snakebite mortality and morbidity, mostly ...

Anti-human erythrocyte antibodies in horse-derived antivenoms used in the treatment of snakebite envenomations 

León Montero, Guillermo; Rodríguez, Miguel Angel; Rucavado Romero, Alexandra; Lomonte, Bruno; Gutiérrez, José María (2007-03)
This work examined the presence of antibodies reacting with human erythrocytes in horse-derived antivenoms used in the treatment of snakebite envenomations, and assessed the efficacy of various fractionation protocols in ...

Understanding structural and functional aspects of PII snake venom metalloproteinases: Characterization of BlatH1, a hemorrhagic dimeric enzyme from the venom of Bothriechis lateralis
