First crotoxin-like phospholipase A2 complex from a New World non-rattlesnake species: Nigroviriditoxin, from the arboreal Neotropical snake Bothriechis nigroviridis
(Toxicon vol 93:144–154, 2015-01)Bothriechis nigroviridis is an arboreal Neotropical pitviper found in Costa Rica and Panam a. A previous proteomic profiling of its venom revealed the presence of proteins with homology to the A and B subunits of ... -
First look into the venom of Roatan Island´s critically endangered coral snake Micrurus ruatanus: proteomic characterization, toxicity, immunorecognition and neutralization by an antivenom
(2019)A proteomic and toxicological study of the venom from one specimen of Micrurus ruatanus, a critically endangered coral snake species endemic to Roatan Island, Honduras, was carried out. Immunorecognition and neutralization ... -
First report of acariasis by Caparinia tripilis in African hedgehogs, (Atelerix albiventris), in Costa Rica
(2013)The African hedgehog is one of the newly imported exotic pets which have been observed with increasing regularity in veterinary clinics in Costa Rica. Despite their popularity, information about their diseases is scarce. ... -
First Report of the Isolation and Molecular Characterization of Rickettsia amblyommii and Rickettsia felis in Central America
(2011-10-05)During 2010, 15 adult ticks, identified as Amblyomma cajennense, were collected from horses in Cahuita and Turrialba districts, whereas 7 fleas, identified as Ctenocephalides felis, were collected from a dog in San Jose ... -
Freeze-dried snake antivenoms formulated with sorbitol, sucrose or mannitol: Comparison of their stability in an accelerated test
(2014-11)Freeze-drying is used to improve the long term stability of pharmaceutical proteins. Sugars and polyols have been successfully used in the stabilization of proteins. However, their use in the development of freeze-dried ... -
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 ... -
Functional analysis of DM64, an antimyotoxic protein with immunoglobulin-like structure from Didelphis marsupialis serum
(2002-12-11)Bothrops snake venoms are known to induce local tissue damage such as hemorrhage and myonecrosis. The opossum Didelphis marsupialis is resistant to these snake venoms and has natural venom inhibitors in its plasma. The aim ... -
Functional, proteomic and transcriptomic characterization of the venom from Micrurus browni browni: identification of the first lethal multimeric neurotoxin in coral snake venom
(2020)Proteomic characterization of Micrurus browni browni venom showed approximately 41 components belonging to 9 protein families, mainly phospholipases A2 (PLA2s) and three-finger toxins (3FTxs). Venom gland transcriptome ... -
Fungicidal activity of a phospholipase A2-derived synthetic peptide variant against Candida albicans
(2007-09)pEM-2, a 13-mer synthetic peptide variant derived from myotoxin II, a phospholipase A2 homologue present in Bothrops asper snake venom, has shown potent bactericidal activity in previous studies due to the combination of ... -
Fur mite, Listrocarpus alouattae Fain (Acari: Atopomelidae), from Alouatta palliata Gray (Primates: Cebidae) in Costa Rica
(2002)Se presentan resultados preliminares de un estudio sobre ectoparásitos de monos de Costa Rica. Se evaluaron 36 monos aulladores (Alouatta palliata Gray, 1849) y 3 monos capuchinos (Cebus capucinus Linnaeus, 1758) provenientes ... -
Gene Expression Dynamics Induced by Ciprofloxacin and Loss of LexA Function in Pseudomonas aeruginosa PAO1 Using Data Mining and Network Analysis
(2018)Pseudomonas aeruginosa is an opportunistic pathogen that causes a variety of infections in humans and frequently develops mechanisms of resistance to antibiotics, which makes its treatment difficult. In this study we ... -
