The genotypes of Mycobacterium leprae isolates originating from Mexico, Peru and Paraguay were analysed for the polymorphism of short tandem repeats in the rpoT gene. The genotype with four copies of the six-base tandem repeats in the rpoT gene was prominently predominant in Mexico, but the genotype of all isolates from Peru and Paraguay contained three copies of the six-base tandem repeats. Th...

We studied the molecular epidemiology of dengue virus type 3 (DENV-3) in Brazil and Paraguay by analyzing the 5' and 3' untranslated regions (5' and 3'UTRs) and the E protein gene of viruses isolated between 2002 and 2004. Both 5' and 3'UTRs were highly conserved. However, the 3'UTR of two isolates from Brazil contained eight nucleotide deletions compared with the remaining 26 viruses. Phylogen...

The article describes two new species of plume moths from Paraguay: Michaelophorus maria sp. n. and Emmelina vera Nine are reported for the fauna Paraguay first time.

Four new species of Cerambycidae are described from Paraguay: Eraninatomentilla (Hemilophini); Mimasyngenesconcolor (Desmiphorini); Recchiadrechseli (Aerenicini); and Microibidionbimaculatum (Neoibidionini). The new species are included in known keys.

Morphological examination of novel specimens of paruterinid cestodes from passerine birds from Brazil and Chile and of museum specimens from Paraguay revealed two new species: Anonchotaenia prolixa sp. n. from Elaenia albiceps chilensis Hellmayr from Chile, and Anonchotaenia vaslata sp. n. from Tyrannus melancholicus (Vieillot) (type host) and Myiodynastes maculatus (Statius Muller) from Paragu...

The taxonomic status of Basileuterus culicivorus complex has been under debate for a long time. There are uncertainties about the relationships among recognized species (B. culicivorus and B. hypoleucus), and whether B. culicivorus can be considered as a single species. In order to elucidate the phylogenetic relationships among these species and their biogeographic history we used a broad geogr...

In the Gran Chaco region, control of Triatoma infestans has been limited by persistent domestic infestations despite the efforts of the Vector Control Services. In Paraguay, this region is the highest endemic area in the country, showing high levels of indoor and outdoor infestation. Although sylvatic T. infestans have been found in the Bolivian and Argentine Chaco, similar searches for sylvati...
