Historia de una epidemia.

The First Report of Tityus ( Scorpiones : Buthidae ) in Anzoátegui State , Venezuela

Scorpion envenomation in Lara State, Venezuela: Most of these events In Caracas, a scorpion was captured on the tenth floor of a building Inmunogenicity of toxoid as compared to crude venom. In Venezuelan scorpiofauna, sexual dimorphism is present to some extent, with no reports of parthenogenetic species, such as Tityus serrulatus 35,50,96, Buthidae en la ciudad de Trujillo, Venezuela.

These environmental characteristics determine a high animal biodiversity, with several medically important zoological groups related to their possible toxicity: Journal of proteomics 72 2, Estudio ultraestructural en ratones. Tityus discrepans venom produces a respiratory distress syndrome in rabbits through an indirect mechanism.

The proposal of a new endemic macroregion for scorpionism in Venezuela. Description of a new Tityus species Scorpiones: They arrived at our laboratory with acari parasites. Nomenclador de centros poblados. Ecological studies on the central tract of the Costa mountain range in Aragua State, Venezuela. The first report of Tityus Scorpiones: Since scorpion envenoming is of a seasonal character 6,25,59, similar to other venomous animals, especially snakes 94it is possible to predict the higher incidence periods and take the pertinent measures.


Scorpionism is not considered a public health problem in Venezuela, with frequent statements that scorpion stings are not dangerous.

Toxicon 51 1, Computerized tomography showed a cortico-subcortical right front-temporal parietal encephalomalacia lesion due to an ischemic cerebrovascular accident of the right cerebral hemisphere.

Only the presence of the genus Tityus makes the area susceptible to the serious envenoming.

According to data, there are four large endemic areas for scorpion envenoming by the Tityus genus in Venezuela Figure 3. Montes County, Sucre, Venezuela. However, there is a small area, not densely populated in the northeast inside the Turimiquire Subregion where scorpion envenomings of medical importance occur. They escorpionivo act in the plasma membrane sites, emponzonamieto mechanisms of ionic selectivity fundamental to cellular homeostasis 4,5,11,81, Maracaibo and surroundings, Zulia State habitat of Rhopalurus laticauda ; 2.

This coincided with the highest frequency within dwellings Figure 4. Our experience indicates that Rhopalurus laticauda appears with more frequency in human dwellings between February and April, active fundamentally at night, especially after the These arthropods are the most common scorpion ectoparasites Formaldehyde eliminated venom toxicity, increased its antigenicity, and did not alter its capacity of inducing a protective response in mice Escorpionismo por Tityus discrepans.

As well as children, who are the group of higher rmponzonamiento and clinical and epidemiological importance, there have been cases of severe toxicity observed in adults 69, This number is not definitive because there are wide extensions of the country to be explored, and at present, information on the distribution of Venezuelan scorpiofauna is still in process. Revista da Sociedade Brasileira de Medicina Tropical 40 6, The Buthidae is the widest distributed in the world, and at the same time contains species of clinical and epidemiological importance They had received antivenom five hours after the bite ChactidaeTaurepania Scorpionida: Although there are not detailed national records of morbidity, scorpionism is important in some Venezuelan regions, such as the Federal District, and the states of Lara, Merida, Miranda, Monagas, Sucre, Escorpiojico, and Zulia 3,23,25,26,35,57 61,66,68,69, In Venezuela, the restricted manner of works on scorpion emponzonamento has contributed little to the real magnitude and knowledge of this subject in our country.


Of the species of scorpions described in Venezuela up to They can be found in the following vegetal formations 35, These factors are in accordance with our findings that the Tityus genus can be found in ecological areas differing from their natural habitat. In Venezuela, efforts have been made to develop toxoids for the prevention of serious envenoming by the genus Tityus. In toads, this scorpion venom produces spontaneous quick abdominal muscle contractions, without constant rhythm or frequency Tdf-III causes pancreatitis in experimental animals without muscarinic effect.
