Sand flies are a group of insects (Diptera, Psychodidae, Phlebotominae) in which some species may transmit agents of leishmaniasis. This study aimed to analyze the sand fly fauna in urban parks in Rio Branco, capital of Acre state, addressing its diversity, infection by Leishmania, and food sources in sand fly females. The sand flies were collected with CDC-type automatic light traps installed in three urban parks in Rio Branco: Captain Ciríaco, Horto Florestal and Chico Mendes.

Article Synopsis
  • Bartonella spp. are bacteria that can cause infections in animals and humans, and they are spread by vectors like sand flies.
  • A study analyzed 634 sand fly specimens in Brazil from 2017-2021 and found that 8.7% contained Bartonella DNA using specific PCR techniques.
  • Phylogenetic analysis indicated some sequences of Bartonella were related to known species, suggesting that sand flies might play a role in the transmission of these bacteria.

Lignin, a major plant cell wall component, has an important role in plant-defense mechanisms against pathogens and is a promising renewable carbon source to produce bio-based chemicals. However, our understanding of microbial metabolism is incomplete regarding certain lignin-related compounds like p-coumaryl and sinapyl alcohols. Here, we reveal peripheral pathways for the catabolism of the three main lignin precursors (p-coumaryl, coniferyl, and sinapyl alcohols) in the plant pathogen Xanthomonas citri.

Trichophoromyia auraensis (Mangabeira, 1942) (Diptera, Psychodidae, Phlebotominae) has a wide geographic distribution in the western region of the Amazon biome, where it is a putative Leishmania vector. Here, we reported for the first time a population of this species in the Brazilian state of Maranhão, in the eastern Amazon, from which we DNA-barcoded and compared with previously processed specimens from Acre State, in the western Amazon. For this, we analyzed the DNA barcoding fragment (658 bp) of the mitochondrial cytochrome c oxidase subunit I (COI) gene and the nuclear internal transcribed spacer 2 (ITS2) of Trichophoromyia species using phylogenetic gene trees, and species delimitation algorithms.

This article describes the development of a participatory methodological study involving autistic people with varying levels of support needs in the design and validation of an instrument devised to assess the effects of social isolation during the COVID-19 pandemic and the strategies used to cope with the crisis. The development of the instrument involved the following stages: Definition of the domains to be assessed (researchers in consultation with experts and autistic people); Design of the instrument (researchers with the co-participation of autistic people); Validation of the instrument (by experts and autistic people, led by the researchers); and Final approval of the instrument (co-participation between researchers and autistic people). In addition to making the instrument more robust, the participation of autistic people in the design and application of the instrument reinforced the importance of strategies to include autistic people in research as both study participants and co-researchers.

Vector-borne diseases are responsible for more than 17% of human cases of infectious diseases. In most situations, effective control of debilitating and deadly vector-bone diseases (VBDs), such as malaria, dengue, chikungunya, yellow fever, Zika and Chagas requires up-to-date, robust and comprehensive information on the presence, diversity, ecology, bionomics and geographic spread of the organisms that carry and transmit the infectious agents. Huge gaps exist in the information related to these vectors, creating an essential need for campaigns to mobilise and share data.

Throughout the 20th and 21st centuries, the incidence of non-communicable diseases (NCDs), also known as chronic diseases, has been increasing worldwide. Changes in dietary and physical activity patterns, along with genetic conditions, are the main factors that modulate the metabolism of individuals, leading to the development of NCDs. Obesity, diabetes, metabolic associated fatty liver disease (MAFLD), and cardiovascular diseases (CVDs) are classified in this group of chronic diseases.

Performance autoethnography is qualitative research methodology that aims to problematize resistances between the "self" (auto-) and the collective (ethno-) in the act of writing (-graphy). The article thus aims to discuss the theoretical and practical construction of performance autoethnography and its applicability as a qualitative research and analytical method in the field of Collective Health through a performance autoethnography writing. By problematizing the epistemic and ontological basis of performance autoethnography, pointing to possibilities for its development and inclusion in studies in the field of Collective Health, the article presents performance autoethnography as a strategy to expand the possibilities for social justice, democratization, and pluralisms in and from research practices.
