AI Article Synopsis
- * 89 tetracycline-resistant isolates carried resistance genes like tetW, tetM, tetA(33), tetK, or tetL; 18 out of 23 erythromycin-resistant isolates had either ermX or ermB.
- * Significant differences in resistance gene prevalence were found between cattle and pig isolates, indicating limited transmission of T. pyogenes between the two species.
Article Abstract
We investigated antimicrobial resistance-related genes in 109 isolates of Trueperella pyogenes that were isolated in cattle and pigs. All 89 tetracycline-resistant T. pyogenes isolates carried the resistance gene harbored either tetW, tetM, tetA(33), tetK, or tetL. The ermX or ermB were detected in 18 of 23 erythromycin-resistant isolates. Streptomycin-resistant aadA1, aadA9, aadA11, aadA24, strA, or strB were detected in 25 of 83 isolates. There were significant differences in the percentages of tetA(33), ermB, aadA1, aadA9, aadA11, or aadA24 carriage between cattle and pig isolates. In addition, the Class 1 gene cassette was detected only in 17 cattle isolates. This suggests that T. pyogenes isolates acquire resistance gene in each environment of cattle and pigs, and that the transmission of the bacteria between cattle and pigs is limited.

Spatiotemporal characteristics and influencing factors of non-CO greenhouse gas emission intensity from China's livestock sector.
Sci Total Environ

Institutes of Science and Development, Chinese Academy of Sciences, Beijing 100190, China; School of Public Policy and Management, University of Chinese Academy of Sciences, Beijing 100049, China.
The livestock sector is a major source of non-CO greenhouse gas (GHG). As China has the world's largest livestock production, analyzing factors influencing GHG emission intensity of livestock (GEIL) is crucial for guiding its emission reduction policies. Yet, most current studies on livestock GHG focus on emission amount (GEAL) over GEIL, neglecting comprehensive utilization of spatial econometric models.

Article Synopsis
- Jumbo phages are large viruses with genomes over 200 kbp, and little is known about their life cycle and unique reproductive genes.
- Researchers assembled 668 high-quality jumbo phage genomes from 955 samples of various animal species and identified the largest known phage genome at 716 kbp, revealing they can synthesize NAD and contain numerous NAD-consuming enzymes.
- The study highlights the widespread presence of NAD-jumbo phages in different ecosystems, emphasizing the need for further research on their ecological roles and survival strategies.
Bovine milk consumption affects the transcriptome of porcine adipose stem cells: Do exosomes play any role?

The potential association of milk with childhood obesity has been widely debated and researched. Milk is known to contain many bioactive compounds as well as bovine exosomes rich in micro-RNA (miR) that can have effects on various cells, including stem cells. Among them, adipose stem cells (ASC) are particularly interesting due to their role in adipose tissue growth and, thus, obesity.

Background: Trends in the development of genetic markers for the purposes of genomic and marker-assisted selection primarily focus on identifying causative polymorphisms. Using these polymorphisms as markers enables a more accurate association between genotype and phenotype. Bioinformatic analysis allows calculating the impact of missense polymorphisms on the structural and functional characteristics of proteins, which makes it promising for identifying causative polymorphisms.
