Venom diversity in the neotropical genus Tityus: implications for antivenom design emerging from molecular and immunochemical analyses across endemic areas of scorpionism
(2020)
Scorpions of the Neotropical genus Tityus are responsible for most severe envenomations in the Caribbean, South America, and Lower Central America (LCA). Although Tityus is taxonomically complex, contains high toxin ...
Vector-borne pathogens in dogs from Costa Rica: First molecular description of Babesia vogeli and Hepatozoon canis infections with a high prevalence of monocytic ehrlichiosis and the manifestations of co-infection
(2014)
Infection with canine vector-borne pathogens was evaluated in dogs from four different
regions of Costa Rica by PCR. Demographic data, clinical signs, packed cell volume values,
and the presence of tick infestation were ...
Detection of Dirofilaria immitis and other arthropod-borne filarioids by an HRM real-time qPCR, blood-concentrating techniques and a serological assay in dogs from Costa Rica
(2015)
Background: Canine filarioids are important nematodes transmitted to dogs by arthropods. Diagnosis of canine
filariosis is accomplished by the microscopic identification of microfilariae, serology or PCR for filarial-DNA. ...
Potent virucidal activity against Flaviviridae of a group IIA phospholipase A2 isolated from the venom of Bothrops asper
(2020)
Secreted phospholipase A2 (sPLA2) molecules are small, calcium-dependent enzymes involved in many biological processes. Viperid venoms possess gIIA sPLA2s and sPLA2-like proteins, both having homology to human gIIA sPLA2, ...
Physical characteristics of nano-Hydroxyapatite Pickering-emulsions and their adjuvant activity on the antibody response towards the Bothros asper snake venom
(2019)
Emulsions are crucial in the treatment of snake bites to bust the antibody response of the inmunogen. The widely used Freund's emulsion typically combines 50/50 water-oil (W/O) phase. However, its use is limited because ...
Snake venomics, experimental toxic activities and clinical characteristics of human envenomation by Bothrocophias myersi (Serpentes: Viperidae) from Colombia
(2020)
Venoms of the viperid genus Bothrocophias, restricted to Colombia and Ecuador, are poorly known. Only a proteomic analysis of B. campbelli venom has been described. In this work we present a proteomic study of B. myersi ...
Pathology and first report of natural eye infection with the trematode Philophthalmus gralli (Digenea, Philophthalmidae) in Tinamus major (Tinamiformes, Tinamidae), Costa Rica
(2013)
The eye-fluke Philophthalmus gralli (Philophthalmidae Looss, 1899) was found in six birds known as great
tinamous (Tinamusmajor) reared in awild animal shelter located in Alajuela, Costa Rica. The birds presented conjunctival ...
Venomics of the Central American Lyre snake Trimorphodon quadruplex (Colubridae: Smith, 1941) from Costa Rica
(2020)
Rear-fanged colubrid snakes include hundreds of species globally that possess a Duvernoy's venom gland and often one-several enlarged rear maxillary teeth. We investigated the venom proteome of the Central American Lyre ...
Leucemia Mieloide Crónica Juvenil. A propósito de un caso
Juvenile Chronic Myelogenous Leukemia. A Case Report
(2019-05-01)
La leucemia Mieloide Crónica (LMC) es una neoplasia mieloproliferativa crónica,
caracterizada por un gen de fusión t(9,22). El curso normal de la enfermedad consta de 3
fases: crónica, acelerada y blástica. En su gran ...
Comparison of the adjuvant activity of emulsions with different physicochemical properties on the antibody response towards the venom of West African carpet viper (Echis ocellatus)
(2017)
Adjuvant emulsions are widely used to enhance the antibody response of the animals used as immunoglobulin source for producing antivenoms. Usually, the adjuvant activity of emulsions is attributed both to their ability to ...
