The rubber tree, , is a neotropical Amazonian species. Despite its high economic value and fungi associated with native individuals, in its original area in Brazil, it has been scarcely investigated and only using culture-dependent methods. Herein, we integrated in silico approaches with novel field/experimental approaches and a case study of shotgun metagenomics and small RNA metatranscriptomics of an adult individual.

Introduction: Freshwater ecosystems provide propitious conditions for the acquisition and spread of antibiotic resistance genes (ARGs), and integrons play an important role in this process.

Material And Methods: In the present study, the diversity of putative environmental integron-cassettes, as well as their potential bacterial hosts in the Velhas River (Brazil), was explored through intI-attC and 16S rRNA amplicons deep sequencing. RESULTS AND DISCUSSION: ORFs related to different biological processes were observed, from DNA integration to oxidation-reduction.

In this study, we characterized Cryptococcus gattii biofilm formation in vitro. There was an increase in the density of metabolically active sessile cells up to 72 h of biofilm formation on polystyrene and glass surfaces. Scanning electron microscopy and confocal laser scanning microscopy analysis revealed that in the early stage of biofilm formation, yeast cells adhered to the abiotic surface as a monolayer.

Article Synopsis
  • Scorpion stings from Tityus serrulatus venom can lead to severe cardiac issues, contributing significantly to mortality among victims.
  • The study describes a newly identified toxin called CPP-Ts, which increases calcium release in heart cells, enhancing their contraction frequency.
  • Additionally, CPP-Ts shows potential for use in drug delivery targeting cancer cell nuclei, highlighting a new subfamily of calcium-active toxins and their biotechnological applications.

Clostridium perfringens alpha toxin, encoded by plc gene, has been implicated in gas gangrene, a life threatening infection. Vaccination is considered one of the best solutions against Clostridium infections. Although studies have identified many low quality clostridial vaccines, the use of recombinant proteins has been considered a promising alternative.

Here we report, for the first time, the complete mitochondrial genome of which, together with other species, are popularly known as tetras. The mitogenome's length is 16,643 bp, containing 13 protein-encoding genes (CDS), two ribosomal RNAs (rRNA), 22 RNA transfer (tRNA) and one control region (D-loop). As for other vertebrates, all genes are encoded on the heavy strand except for and eight genes.

, commonly known as Great-billed Seed-Finch or 'bicudo', is a trafficked bird in Brazil due to the species' beauty and singing, which is appreciated by breeders and collectors. Generally, the Environmental Military Police and IBAMA maintain enforcement actions, rescue work, and seizure of illegally traded of 'bicudo' specimens. The genomic DNA of one specimen was sequenced on MiSeq (Illumina) sequencer.

  • * The control region, known as the D-loop, is found to be shorter compared to similar mitochondrial genomes from Asian hylids.
  • * Phylogenetic analysis using homologous genes did not support the idea that the Hylidae family is a monophyletic group, nor did it affirm recent claims about the monophyly of certain subgroups within Hylidae.

Article Synopsis
  • Spiders from the Loxosceles genus can be dangerous to humans due to the harmful effects of their bites, which mainly cause skin death (dermonecrosis) and, less commonly, systemic issues like blood cell destruction and clotting problems.
  • While the overall effects of the venom are understood, the specific cellular death mechanisms it triggers were not well studied until now.
  • This research focused on the venom of the Loxosceles similis spider, finding that it causes cell death in human skin cells through a process called apoptosis, involving specific enzymes known as caspases.

Background: Scorpionism is a public health problem in Brazil, and Tityus serrulatus (Ts) is primarily responsible for severe accidents. The main toxic components of Ts venom are low-molecular-weight neurotoxins; however, the venom also contains poorly characterized high-molecular-weight enzymes. Hyaluronidase is one such enzyme that has been poorly characterized.
