Harnessing microbial metabolism and nutrition to target the gut–mammary axis for better livestock production and health

iMetaOmics, EarlyView.
The gut–mammary axis integrates intestinal health with mammary function through neural, endocrine, and immune pathways. Nutritional interventions (probiotics, prebiotics, metabolites) improve gut microecology, generating microbial signals that travel via the axis to the mammary gland. There, they relieve inflammation, enhance milk quality and lactation,

Characterization of Lactococcus lactis phage antigens [PDF]

Applied and Environmental Microbiology, 1992
Phage phi 197 is representative of a widespread lactococcal phage group characterized by a particular morphology (prolate head with a noncontractile tail). In order to develop an immunoenzymatic phage detection test, fusion proteins containing beta-galactosidase fused to epitopes of phage phi 197 structural proteins were constructed by cloning random ...

Physicochemical properties, fermentative profile, microbiological quality, and pathogen contamination of baled silage during long‐term storage

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Baled silage is expanding in Mediterranean regions due to climate change and demand for high‐quality forage; therefore, evaluating the effects of long‐term storage on microbiological and fermentative quality is essential. RESULTS In this study, 115 baled silages were sampled from different farms at 30, 60, 90, 180, and 270 days ...

Characterization of the Lactococcus lactis Nisin A Operon Genes nisP, Encoding a Subtilisin-Like Serine Protease Involved in Precursor Processing, and nisR, Encoding a Regulatory Protein Involved in Nisin Biosynthesis [PDF]

, 1993
Biosynthesis of the lantibiotic peptide nisin by Lactococcus lactis NIZO R5 relies on the presence of the conjugative transposon Tn5276 in the chromosome. A 12-kb DNA fragment of Tn5276 including the nisA gene and about 10 kb of downstream DNA was cloned
