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.
Article Synopsis
- Fish stocking programs were initiated to help migratory fish overcome barriers created by hydropower dams, but they have raised genetic concerns for local fish populations.
- A study conducted on Neotropical migratory fish in Brazil's Três Marias dam revealed low genetic diversity and inbreeding, with only four distinct genetic pools identified.
- The successful transposition of genetic pools resulted in genetic homogenization in the upper São Francisco River basin, highlighting the species' genetic fragility and the need for effective conservation strategies.
Article Synopsis
- Genetic diversity and population studies are crucial for wildlife conservation, but current monitoring methods are often time-consuming and costly.
- The authors developed a low-cost, efficient genotyping method using next-generation sequencing (NGS) that can analyze up to 384 samples simultaneously with microsatellites.
- Their approach uses a new process with combinatorial barcoding and bioinformatics to streamline data collection, making it a promising tool for large-scale conservation genetics research.
Detection of microbial enzymes in natural environments is important to understand biochemical activities and to verify the biotechnological potential of the microorganisms. In the present report, 346 isolates from soil, water, and plants were screened for enzyme production (caseinase, gelatinase, amylase, carboxymethyl cellulase, and esterase). Our results showed that 89.

Forty-two water buffalo mozzarella samples were purchased from retail outlets in Belo Horizonte. In addition, five samples of consecutive starter cultures, curd before acidification, acidified curd and mozzarella were collected at an industry in the city of Oliveira.
