The oral cavity is the portal of entry for many microorganisms that affect swine, and the swine oral fluid has been used as a specimen for the diagnosis of several infectious diseases. The oral microbiota has been shown to play important roles in humans, such as protection against non-indigenous bacteria. In swine, studies that have investigated the microbial composition of the oral cavity of pigs are scarce.

- This study used metagenomics to explore the connection between chicken feces' physical characteristics and their bacterial content, focusing on samples collected from 19-day-old broilers.
- The research classified feces into groups based on two morphological traits—feed passage (FP) and reddish mucus (RM)—each ranked by intensity, and analyzed various bacteria through sequencing.
- Findings highlighted that the cecal discharge (CD) group had greater diversity and distinct bacterial profiles compared to other groups, indicating the importance of fecal morphology in understanding microbiota composition.
Hatchery tanks induce intense reduction in microbiota diversity associated with gills and guts of two endemic species of the São Francisco River.

The São Francisco River (SFR), one of the main Brazilian rivers, has suffered cumulative anthropogenic impacts, leading to ever-decreasing fish stocks and environmental, economic, and social consequences. and are medium-sized, bottom-feeding, and rheophilic fishes from the SFR that suffer from these actions. Both species are targeted for spawning and restocking operations due to their relevance in artisanal fisheries, commercial activities, and conservation concerns.

However, technical difficulties in measuring feed efficiency traits had limited the application in livestock. Here, we performed a Bivariate Genome-Wide Association Study (Bi-GWAS) and presented candidate biological mechanisms underlying the association between feed efficiency and meat quality traits in a half-sibling design with 353 Nelore steers derived from 34 unrelated sires.

Background: Domestic pigeons carry pathogens in their droppings, posing a potential public health problem.
Methods: The phenotypic and genotypic antimicrobial resistances of Staphylococcus aureus and Enterococcus faecium in the feces of urban pigeons near hospitals with intensive care units were measured.
Results: Twenty-nine samples showed Enterococcus growth, whereas one was positive for S.
