Wang, Yue published the artcileCoupling 16S rDNA Sequencing and Untargeted Mass Spectrometry for Milk Microbial Composition and Metabolites from Dairy Cows with Clinical and Subclinical Mastitis, Category: esters-buliding-blocks, the main research area is dairy milk microbial metabolite mastitis MS; dairy cow; mastitis; metabolomics; microbiota; milk.
The internal environment of the cow′s udder directly affects the udder health and milk quality. 16S rDNA sequencing and liquid chromatog.-mass spectrometry (LC-MS) methods were used to investigate the significant differences in milk microbial diversity and metabolites among cows that are healthy (H) and those suffering from subclin. mastitis (SM) and clin. mastitis (CM). Results uncovered more than 16 and 192 differently abundant microbiota at the phylum and genus levels, resp., and 673 different levels of metabolites enriched in 20 pathways in milk among the 3 groups. This study revealed the pos. relevance between Staphylococcus and Streptococcus and ceramide in milk from CM cows. Similarly, Acinetobacter and Corynebacterium were pos. associated with testosterone glucuronide and 5-methyl-tetrahydrofolate, in milk from SM cows. On the basis of the combined anal. of microbiome and metabolome, this study indicated that, apart from the exogenous pathogens, some beneficial symbiotic bacteria, such as Dietzia, Aeromicrobium, Alistipes, and Sphingobacterium, rarely reported in milk have been found to be significantly reduced during mastitis.
