2. First record of Acanthocephala parasites eggs in coprolites preliminary assigned to Crocodyliformes from the Adamantina Formation (Bauru Group, Upper Cretaceous), São Paulo, Brazil
Abstract Abstract: This study presents the oldest record of Acanthocephala parasite eggs in coprolites preliminary assigned to Crocodyliformes, recovered in the region of Santo Anastácio Municipality, Southwestern São Paulo State. For this, a paleoparasitological investigation was carried out on 53 mineralized coprolites (complete or fragmented), with roun

3. Detection of Wuchereria bancrofti DNA in paired serum and urine samples using polymerase chain reaction-based systems
The Global Program for the Elimination of Lymphatic Filariasis (GPELF) aims to eliminate this disease by the year 2020. However, the development of more specific and sensitive tests is important for the success of the GPELF. The present study aimed to standardise polymerase chain reaction (PCR)-based systems for the diagnosis of filariasis in serum and urine

4. The existence of only one haplotype of Leishmania major in the main and potential reservoir hosts of zoonotic cutaneous leishmaniasis using different molecular markers in a focal area in Iran
IntroductionLeishmania major is the causative agent of zoonotic cutaneous leishmaniasis (ZCL), and great gerbils are the main reservoir hosts in Iran. Abarkouh in central Iran is an emerging focal point for which the reservoir hosts of ZCL are unclear. This research project was designed to detect any Leishmania parasites in different wild rodent species.Meth

5. Molecular detection of Schistosoma japonicum in infected snails and mouse faeces using a real-time PCR assay with FRET hybridisation probes
A real-time polymerase chain reaction (PCR) assay with fluorescence resonance energy transfer (FRET) hybridisation probes combined with melting curve analysis was developed to detect Schistosoma japonicum in experimentally infected snails and in faecal samples of infected mice. This procedure is based on melting curve analysis of a hybrid between an amplicon

6. Rhabdias paraensis sp. nov.: a parasite of the lungs of Rhinella marina (Amphibia: Bufonidae) from Brazilian Amazonia
The nematode parasites of Rhinella marina include species of the genus Rhabdias (Rhabdiasidae: Rhabditoidea). The present study describes Rhabdias paraensis sp. nov., which parasitizes the lungs of R. marina in Brazilian Amazonia. Of the more than 70 known species of this genus, 18 are parasites of bufonids, of which, eight are Neotropical. The new species d

7. Caracterização fisiológica e genética do transporte de arginina em Leishmania (Leishmania) amazonensis / Physiologic and genetic characterization of arginine transport in Leishmania (Leishmania) amazonensis
Protozoan of genus Leishmania are digenetic parasites that present a stage in the life in insect gut (promastigotes) and an intracellular phase (amastigotes) inside vertebrate host macrophages. The study of L-arginine influx consists in an interesting matter, since the amino acid is used on NO production pathway (the main macrophage microbial pathway) but ar

8. Desenvolvimento e avaliação da atividade e farmacocinética de nanopartículas lipídicas sólidas contendo a associação de quinina e doxiciclina / Development and evaluation of the activity and pharmacokinetics of solid lipid nanoparticles loaded with the association of Quinine and Doxycycline
Malaria is one of the most devastating tropical diseases caused by intracellular protozoan parasites of the genus Plasmodium. More than 3 billion people live in malarial endemic regions. Five species of Plasmodium (falciparum, vivax, ovale, malariae and knowlesi) cause disease in humans and infection with P. falciparum, the most deadly of these parasites, re

9. Nested PCR to detect and distinguish the sympatric filarial species Onchocerca volvulus, Mansonella ozzardi and Mansonella perstans in the Amazon Region
We present filaria-nested polymerase chain reaction (PCR), which is based on amplification of first internal transcribed spacer rDNA to distinguish three parasitic filarial species (Onchocerca volvulus, Mansonella ozzardiand Mansonella perstans) that can be found in the Amazon Region. Nested PCR-based identifications yielded the same results as those utilizi

10. CA88, a nuclear repetitive DNA sequence identified in Schistosoma mansoni, aids in the genotyping of nine Schistosoma species of medical and veterinary importance
CA88 is the first long nuclear repetitive DNA sequence identified in the blood fluke, Schistosoma mansoni. The assembled S. mansoni sequence, which contains the CA88 repeat, has 8,887 nucleotides and at least three repeat units of approximately 360 bp. In addition, CA88 also possesses an internal CA microsatellite, identified as SmBr18. Both PCR and BLAST an

11. Biomarkers of Environmental Contamination in athorops spixii inthe Santos/ São Vicente and Cananéia estuarines, São Paulo, Brazil / Biomarcadores de contaminação ambiental em Cathorops spixii nos Estuários de Santos/São Vicente e Cananéia, São Paulo, Brasil
The aim of this study was to characterize the contamination processes in Santos/São Vicente and Cananéia estuaries; and to study somatic, biochemical, genotoxic and morphological biomarkers in Cathorops spixii. The results of hydrochemistry, nutrients and total mercury concentration confirmed the largest human influence in Santos/São Vicente estuary, main

12. Theileria electrophorin.sp., a parasite of the electric eel Electrophorus electricus (Osteichthyes: Cypriniformes: Gymnotidae) from Amazonian Brazil
The name Theileria electrophori n.sp. is proposed for a small parasite described in the erythrocytes of the electric eel, Electrophorus electricus, from Amazonian Brazil. Division of the organism in the erythrocyte produces only four bacilliform daughter cells which become scattered in the host cell, without a cruciform or rosette-shaped disposition. Exoeryt
