Summary: This study investigated the microRNA (miRNA) cargos of exosomes isolated from milk in relation to the healthy conditions of the mammary gland. Differential expression analysis identified differentially expressed miRNAs in the comparisons between healthy cows, cows at risk of mastitis, and cows with subclinical mastitis. The analysis of miRNA cargos in milk exosomes can be considered as a promising approach to study the complex molecular machinery set in motion in response to mastitis in dairy cows.

Summary: Extracellular vesicles in milk play important roles in mastitis development. This study analyzed milk-derived extracellular vesicles from cows with mastitis and healthy cows using proteomic analysis. Results showed that mammary inflammation alters milk-derived extracellular vesicle protein cargos, particularly antimicrobial peptides. These findings provide valuable insights into the functions and pathways of milk-derived extracellular vesicle proteins.

Summary: This observational study investigated the lipidome of cow milk during subclinical intramammary infection caused by non-aureus staphylococci using an untargeted approach. The results showed significant changes in lipid species belonging to triacylglycerols and sphingomyelins in quarter milk with NAS-IMI, potentially serving as novel biomarkers for improving mastitis diagnostics.

Summary: This study investigated the distribution of non-aureus staphylococci and closely related mammaliicoccal species in composite cow milk and bulk-tank milk samples from commercial Flemish dairy herds. The results showed herd-specific NASM microbiota and variations within NASM species. Strain typing analysis provided insights into the origin and diversity of NASM species.

Summary: Modern dairy cattle farms have intensified greatly to meet the global demand for fresh milk, leading to increased concern for health and welfare risks. This study investigated the impact of various factors on milk quality and found that longer lactation periods and teat hyperkeratosis significantly decreased milk quality and increased somatic cell counts. Udder cleanliness and teat size also had a negative effect on protein content.

Summary: The study in major milk-producing areas of Sri Lanka found that subclinical mastitis (SCM) has a high prevalence and is mainly caused by Staphylococcus aureus. Logistic regression analysis showed that the prevalence of SCM is influenced by factors such as parity, farming system, and region. SCM affects the number of artificial inseminations and the days from calving to artificial insemination in dairy cows.

Summary: Houseflies may serve as potential carriers of Mycoplasma spp., as they harbor strains that are genetically similar to those found in milk. These flies possess multiple pathogenicity genes. Understanding transmission routes is crucial for preventing and controlling the spread of this pathogen.

Summary: This study focused on describing bedding bacterial counts, pH, and dry matter of five different bedding types and exploring the association between bedding bacterial counts with bulk tank milk quality. Results showed that organic materials had higher bacterial levels compared to inorganic materials, indicating variability in bacterial growth among different bedding types. No significant associations were found between the bacterial counts in bedding samples and bulk tank milk quality, suggesting potential limitations in using bedding type as a predictor for milk quality.

Summary: The study indicated that bacterial isolates from organic herds had lower antibiotic resistance compared to herds using dry cow therapy (DCT). However, the differences in MIC distributions occurred below clinical breakpoints, suggesting that bacteriological cure rates may not be affected by isolates with different MIC levels.

Summary: This study aimed to investigate the association between bulk tank somatic cell count (SCC) and dairy farmers' knowledge about milk quality, mastitis control, and their socioeconomic characteristics. The results showed significant associations between SCC and parameters such as the economic impact of mastitis, milking procedures, methods for subclinical mastitis detection, and awareness of legal requirements for SCC and total bacterial count (TBC). These findings highlight the importance of knowledge and socioeconomic profiles in maintaining and enhancing milk quality in dairy herds.

Summary: This observational study aimed to explore the association between milk somatic cell count (SCC) and subclinical intramammary infection (IMI) and determine the optimal SCC cut-point for diagnosing IMI. The study found that in Irish pasture-based dairy herds with low bulk tank SCC, the last test-day SCC was the best predictor of IMI in late lactation.

Summary: The study found that the prevalence of mastitis in dairy cows, camels, and goats was 33.3%, 26.3%, and 25%, respectively, with major bacterial isolates such as coagulase-negative Staphylococcus and S. aureus. In camels, udder abnormalities and mastitis were more common in late lactation.

Summary: This study characterized the lncRNA profiles in mammary epithelial cells of dairy cows using RNA-sequencing technology, and identified 14 specific lncRNAs related to selenium and their predicted target genes. Functional annotation was used to elucidate the biological function and potential pathways involved. The findings provide novel insights for exploring molecular markers for protecting against mastitis in dairy cows.

Summary: Cow's milk contains potential allergens in the form of proteins, making some infants, children, and adults allergic to cow's milk. Strict exclusion of milk and other dairy products puts children with cow's milk allergy at higher nutritional risk.

Summary: The use of antimicrobials in food-producing animals is facing increased scrutiny and regulations to maintain the efficacy of antimicrobials for human diseases. Consumers are skeptical about antibiotic use in dairy cows, while dairy producers and veterinarians have mixed feelings about reducing antimicrobial usage and animal welfare. Antimicrobial stewardship focuses on preventing bacterial diseases and using evidence-based treatment protocols. Implementing antimicrobial stewardship in the dairy industry requires recognizing appropriate usage and understanding the benefits. This paper defines elements of antimicrobial stewardship in dairy practice and discusses the challenges and potential benefits.

Summary: This study aimed to describe the occurrence and treatment of mastitis and other common bovine diseases using retrospective observational data from large dairy farms in Wisconsin. Clinical mastitis is the most diagnosed disease among dairy cows, and a significant number of cows do not receive antibiotics after being diagnosed.
