Increased Infectivity of Staphylococcus aureus in an Experimental Model of Snake Venom–Induced Tissue Damage
(2007-09-01)
Soft-tissue infection is commonly found in patients bitten by Latin American Bothrops snakes. Staphylococcus aureus, which is not present in the mouth of the snake, is frequently isolated from these infections. The effects ...
Pathological changes induced by BaH1, a hemorrhagic proteinase isolated from Bothrops asper (Terciopelo) snake venom, on mouse capillary blood vessels
(1994-08)
The pathological changes induced in capillaries by BaH1, a hemorrhagic metalloproteinase isolated from the venom of Bothrops asper, were studied after i.m. injection in mouse gastrocnemius. Hemorrhage was observed ...
Unresolved issues in the understanding of the pathogenesis of local tissue damage induced by snake venoms
(2018-06)
Snakebite envenoming by viperid species, and by some elapids, is characterized by a complex pattern of
tissue damage at the anatomical site of venom injection. In severe cases, tissue destruction may be so
extensive as ...
Hemorrhage induced by snake venom metalloproteinases: biochemical and biophysical mechanisms involved in microvessel damage
(2005-06-15)
Zinc-dependent metalloproteinases are responsible for the hemorrhagic activity characteristic of viperid snake venoms. Snake venom metalloproteinases (SVMPs) are classified in various groups (P-I–IV), according to their ...
Anticomplementary activity of equine whole IgG antivenoms: comparison of three fractionation protocols
(2005-01)
Early adverse reactions occur in a number of patients treated with heterologous antivenoms and have been associated with anticomplementary activity (ACA). In order to reduce the ACA of equine whole IgG antivenoms produced ...
Pathogenesis of myonecrosis induced by coral snake (Micrurus nigrocinctus) venom in mice
(1986-02)
The mode by which coral snake (Micrurus nigrocinctus) venom affects skeletal muscle was studied using a combined approach. The venom induced early functional and structural alterations in the plasma membrane of muscle ...
Exploration of immunoglobulin transcriptomes from mice immunized with three-finger toxins and phospholipases A2 from the Central American coral snake, Micrurus nigrocinctus
(2017)
Snakebite envenomings represent a neglected public health issue in many parts of the
rural tropical world. Animal-derived antivenoms have existed for more than a hundred
years and are effective in neutralizing snake venom ...
From Fangs to Pharmacology: The Future of Snakebite Envenoming Therapy
(2016)
The snake is the symbol of medicine due to its association with Asclepius, the
Greek God of medicine, and so with good reasons. More than 725 species of venomous
snakes have toxins specifically evolved to exert potent ...
Combined venom gland cDNA sequencing and venomics of the New Guinea small-eyed snake, Micropechis ikaheka
(2014-10-14)
The venom arsenal of the New Guinea small-eyed snake, Micropechis ikaheka, was investigated by a joint cDNA sequencing and venomics approach. Twenty-seven full-length DNA sequences encoding novel venom proteins were recovered ...
Neutralización de las actividades tóxicas y enzimáticas de cuatro venenos de serpientes de Guatemala y Honduras por el antiveneno polivalente producido en Costa Rica
(1987)
We studied the ability of the polyvalent antivenom produced in Costa Rica to neutralize lethal, hemorrhagic, edema-forming, proteolytic, hemolytic, hyaluronidase and fibrinolytic activities of the venoms of Bothrops asper ...
