Chiropterans play an important role in the maintenance of the environmental balance, since they are pollinators, seed dispersers and predators. They contribute to transmission and spreading of microorganisms such as helminths, fungi, protozoa, bacteria and virus. The aim of the present study was to investigate natural filariid infection among bats in the Legal Amazon region, Brazil, by means of parasitological and molecular analyses. Blood samples were collected from 82 bats for blood smears and for DNA extraction via the polymerase chain reaction (PCR) assay. Microfilariae were observed in blood smears from Carollia perspicillata (2), Artibeus lituratus (1), Artibeus fimbriatus (2), Dermanura gnoma (2) and Glossophaga soricina (1). Five positive samples were detected through the PCR assay and four of these were also positive in blood smears. From genome sequencing and comparative analysis with sequences deposited in GenBank, one sample showed 99.31% similarity to the species Litomosoides brasiliensis. The present study expands the geographical distribution of L. brasiliensis, to include the state of Maranhão as an area of occurrence of this species and includes D. gnoma and A. fimbriatus as hosts in Brazil.

de sobrepeso e obesidade na infância e adolescência. Através de palestras e apresentações do teatro de fantoches, os alunos aprenderam de forma lúdica o que é DM, o que comer e evitar para prevenir e tratar a doença, como calcular IMC, a importância da atividade física no controle do peso e a importância de exame de glicemia para diagnóstico da doença. Em suma, o estudo confirmou que há correlação entre IMC e glicemia, ressaltando a importância de medidas preventivas para DM2 entre crianças e adolescentes, já que obesidade frequentemente precede este tipo de diabetes.
