1. Second capture of Promops centralis (Chiroptera) in French Guiana after 28 years of mist-netting and description of its echolocation and distress calls
RESUMEN La cuenca amazónica alberga algunos de los ecosistemas más diversos en fauna quiropterológica del mundo. Sin embargo, en la literatura científica no encontramos información muy detallada sobre especies de murciélago esquivas como las de la família Molossidae. Esta carencia condiciona y obstaculiza los esfuerzos de conservación tanto a escala

2. Diversity, natural infection and blood meal sources of phlebotomine sandflies (Diptera, Psychodidae) in the western Brazilian Amazon
BACKGROUND The state of Rondônia (RO) is a hot spot for human cases of cutaneous leishmaniasis. Many sandfly species in RO are putative vectors of leishmaniasis. OBJECTIVES This study examines the diversity patterns and the presence of Leishmania DNA and blood meal sources of sandflies in RO. METHODS A sandfly survey was performed between 2016 and 201

3. Does the widely distributed rodent Calomys tener (Cricetidae: Sigmodontinae) constitute a single evolutionary unit?
ABSTRACT The nominal species Calomys tener (Winge, 1887) ranges broadly in open lands of the Caatinga, Cerrado, Pantanal and Mata Atlântica of Brazil, and was recently reported from the Pampas of southern Brazil, and in the Selva Paranaense of eastern Paraguay and northeastern Argentina. This rodent can be infected with the pathogenic Araraquara hantavirus

4. Population structure and genetic diversity of the giant anteater (Myrmecophaga tridactyla: Myrmecophagidae, Pilosa) in Brazil
Abstract The giant anteater (Myrmecophaga tridactyla, Pilosa, Linnaeus 1758) belongs to the mammalian order Pilosa and presents a large distribution along South America, occupying a great variety of habitats. It is listed in the IUCN Red List of threatened species as Vulnerable. Despite threatened, there is a lack of studies regarding its genetic variability

5. Phylogeographic history of South American populations of the silky anteater Cyclopes didactylus (Pilosa: Cyclopedidae)
Abstract Cyclopes didactylus, commonly called silky anteater, is the smallest and least studied of the anteaters. It is an arboreal species occurring in rainforests, ranging from southern Mexico to Central and South America, with an apparently disjoint distribution between Amazon and Atlantic rainforests in Brazil. Although seven subspecies are recognized, l

6. PERFORMANCE OF CONVENTIONAL PCRs BASED ON PRIMERS DIRECTED TO NUCLEAR AND MITOCHONDRIAL GENES FOR THE DETECTION AND IDENTIFICATION OF Leishmania spp.
In visceral leishmaniasis, the detection of the agent is of paramount importance to identify reservoirs of infection. Here, we evaluated the diagnostic attributes of PCRs based on primers directed to cytochrome-B (cytB), cytochrome-oxidase-subunit II (coxII), cytochrome-C (cytC), and the minicircle-kDNA. Although PCRs directed to cytB, coxII, cytC were able

7. Filogenia molecular de Toxoplasmatinae: comparação entre inferências baseadas em sequências genéticas mitocondriais e de apicoplasto
Resumo A filogenia da subfamília Toxoplasmatinae tem sido amplamente investigada com diversos marcadores moleculares. Neste estudo, a filogenia molecular da subfamília Toxoplasmatinae foi analisada através de genes de apicoplasto e mitocondriais. Foram analisadas sequências parciais de genes de apicoplasto codificadores da protease caseinolítica (clpC),

8. Uso de RFLP-PCR para a detecção de isolados de Venturia inaequalis resistentes ao cresoxim metílico do Sul do Brasil
O principal mecanismo que confere resistência do fungo Venturia inaequalis aos inibidores de oxidação (quinol QoIs) é a ocorrência de mutações no gene citocromo b CYTB (G143A). O objetivo do trabalho foi a implementação da metodologia RFLP-PCR para caracterizar a reação de isolados de V. inaequalis à presença de Qols. Foram utilizados sete isola

9. Identification of blood meal sources of Lutzomyia longipalpis using polymerase chain reaction-restriction fragment length polymorphism analysis of the cytochrome B gene
An analysis of the dietary content of haematophagous insects can provide important information about the transmission networks of certain zoonoses. The present study evaluated the potential of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis of the mitochondrial cytochrome B (cytb) gene to differentiate between vertebrat

10. Genetic variation in the Cytbgene of human cerebral Taenia soliumcysticerci recovered from clinically and radiologically heterogeneous patients with neurocysticercosis
Neurocysticercosis (NC) is a clinically and radiologically heterogeneous parasitic disease caused by the establishment of larval Taenia solium in the human central nervous system. Host and/or parasite variations may be related to this observed heterogeneity. Genetic differences between pig and human-derived T. solium cysticerci have been reported previously.

11. Diagnóstico, caracterização molecular e epidemiologia de Trypanosamas de ungulados. / Diagnosis, molecular characterization and epidemiology of Trypanosame of ungulates.
Trypanosamas de diversas espécies podem infectar mamíferos de interesse econômico em todo o mundo. Trypanosoma vivax, T. evansi, T. equiperdum, T. congolense, T. b. brucei e T. simiae geram importantes doenças em ungulados na África, Ásia e Américas Central e do Sul; enquanto T. theileri e espécies relacionadas são pouco patogênicas.
