Mammalian milk contains a variety of complex bioactive and nutritional components and microorganisms. These microorganisms have diverse compositions and functional roles that impact host health and disease pathophysiology, especially mastitis. The advent and use of high throughput omics technologies, including metagenomics, metatranscriptomics, metaproteomics, metametabolomics, as well as culturomics in milk microbiome studies suggest strong relationships between host phenotype and milk microbiome signatures in mastitis.

A facultative anaerobic, Gram-stain-negative, non-motile, rod-shaped bacterial strain AGMB14963 was isolated from the feces of a dairy cow. A 16S rRNA gene sequence-based phylogenetic analysis revealed that strain AGMB14963 belongs to the genus Gallibacterium, with Gallibacterium salpingitidis F150 being the closest species (95.8% 16S rRNA gene sequence similarity).

are opportunistic pathogens which can cause mastitis in dairy cattle. mastitis often has a poor cure rate and can lead to the development of chronic infection, which has an impact on both health and production. However, there are few studies which aim to fully characterize by whole-genome sequencing from bovine mastitis cases.

Background: The rumen harbors a diverse virome that interacts with other microorganisms, playing pivotal roles in modulating metabolic processes within the rumen environment. However, the characterization of rumen viruses remains incomplete, and their association with production traits, such as feed efficiency (FE), has not been documented. In this study, rumen fluid from 30 Chinese Holstein dairy cows was analyzed using next-generation sequencing (NGS) and High-Fidelity (HiFi) sequencing to elucidate the rumen DNA virome profile and uncover potential viral mechanisms influencing FE.

Human brucellosis is a re-emerging disease in Sichuan Province, China. In this study, bacteriology, conventional bio-typing, multi-locus sequence typing (MLST), and multiple locus variable-number tandem repeat analysis (MLVA) were applied to preliminarily characterize the strains in terms of genetic diversity and epidemiological links. A total of 101 Brucella strains were isolated from 16 cities (autonomous prefectures) from 2014 to 2021, and all of the strains were identified as Brucella melitensis bv.
