Epidemic outbreaks of dengue fever (DF) were first recorded in Venezuela in 1978 and were followed by the emergence of dengue haemorrhagic fever (DHF) outbreaks in 1989. To gain a better understanding of the nature of these epidemics, the complete envelope (E) gene sequence of 34 Venezuelan dengue type 2 (DEN-2) viruses, isolated between 1997 and 2000 was determined. Of these isolates, 16 were ...

Arid zones of northern Venezuela are represented by isolated areas, important from an ornithological and ecological perspective due to the occurrence of restricted-range species of birds. We analysed the prevalence and molecular diversity of haemosporidian parasites of wild birds in this region by screening 527 individuals (11 families and 20 species) for parasite mitochondrial DNA. The overall...

This article compares the early phases of constitutional redrafting processes in Venezuela (1999) and currently Chile (2021), seeking to identify key factors that help explain radical constitutional-redrafting path was followed Venezuela, versus more moderate, consensual rule-bounded transformation underway Chile. We pay particular attention presence Hugo Chávez as leader a populist project Ven...

Lobomycosis is a chronic dermal infection that presents a wide spectrum of clinical- dermatological manifestations, mainly characterized by the development of keloid lesions as well as nodular, verrucoid and sometimes ulcerous forms. The etiological agent at an international level, according to the consensus nomenclature, has been called Loboa loboi, even though recently it has been accommodate...

We solve saddle point problems by accelerated versions of the classical Cimmino’s method. For that, saddle point problems are reviewed and reformulated as best approximation problems. In that setting, low-cost optimization techniques are used for accelerating Cimmino’s method. Encouraging numerical results coming from KKT systems, Stokes problems and domain decomposition problems are presented....

A new species, Carabodes venezolanus is described from Venezuela. A comparison with related species and genera is done.

A photomap of larval polytene chromosomes of Anopheles nuneztovari (population B) from western Venezuela is presented. Samples of An. nuneztovari B taken from 4 study sites in the states of Barinas and Táchira comprise a single panmictic population, which is chromosomally identical to the cytotype identified by Kitzmiller et al. (1973) from western Venezuela and Colombia. The frequency of polym...

Paracoccidioidomycosis is a systemic mycosis which is endemic in rural areas of Latin America, an important European source of immigrants and a growing European touristic destination as well, with most cases occurring in Brazil, Argentina, Venezuela and Colombia. The authors report a case of a 43 year old man who previously worked in Venezuela and is living in Portugal for 8 years, presenting w...
