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 ...
Caprylic acid fractionation of hyperimmune horse plasma: description of a simple procedure for antivenom production
(1994)
A simple methodology for hyperimmune horse plasma fractionation, based on caprylic acid precipitation, is described. Optimal conditions for fractionation were studied; the method gives best results when concentrated caprylic ...
An alternative in vitro method for testing the potency of the polyvalent antivenom produced in Costa Rica
(1988)
The ability of several batches of polyvalent antivenom to neutralize indirect hemolytic activity of Bothrops asper venom was studied using a sensitive plate test. All samples of antivenom tested effectively neutralized ...
Inhibition of toxic activities of Bothrops asper venom and other crotalid snake venoms by a novel neutralizing mixture
(1997-12)
The majority of snake bites in Central America are caused by Bothrops asper, whose venom induce complex local effects such as myonecrosis, edema and especially hemorrhage. These effects are only partially neutralized by ...
Inhibition by CaNa2EDTA of local tissue damage induced by Bothrops asper (terciopelo) venom: Application in horse immunization for antivenom production
(1998-03-26)
The ability of the chelating agent CaNa2EDTA to inhibit local tissue damage induced by Bothrops asper venom was studied in mice and in horses used for polyvalent (Crotalinae) antivenom production. CaNa2EDTA was devoid of ...
A new method for the detection of phospholipase A2 variants: identification of isozymes in the venoms of newborn and adult Bothrops asper (terciopelo) snakes
(1988)
A new method for the identification of phospholipase A2 isozymes in snake venoms is described. The technique is based on the separation of the venom components by isoelectric focusing in agarose gels, transfer of the protein ...
Venom Composition and Diet of the Cantil Agkistrodon bilineatus howardgloydi (Serpentes: Viperidae)
(1999-12)
The southernmost subspecies of the cantil, Agkistrodon bilineatus howardgloydi, occurs in almost all terrestrial habitats of the sector Santa Rosa National Park, in Guanacaste Conservation Area, Costa Rica. We obtained 21 ...
Turbidity of hyperimmune equine antivenom: the role of phenol and serum lipoproteins
(1993)
Twenty batches of polyvalent antivenom produced at the Instituto Clodomiro Picado were analyzed for turbidity, both before and after freezing-thawing and lyophilization. Eight batches became turbid upon freezing-thawing, ...
Isolation of basic myotoxins from Bothrops Moojeni and Bothrops Atrox snake venoms
(1990)
Three myotoxins, one from the venom of Bothrops atrox and two from the venom of B. moojeni, were isolated by ion-exchange chromatography on CM-Sephadex C-25. The three toxins are basic proteins with an estimated mol. wt ...
