Summary: This study conducted a comprehensive analysis of bovine mastitis-associated S. aureus isolates from India using whole genome sequencing and comparative genomic analysis. The results revealed 15 different sequence types and 5 clonal complexes. The genome of Indian mastitis-associated S. aureus strains is relatively closed. Phylogenetic analysis based on SNP variation differentiated the 41 strains into six major clades. Seventeen different antimicrobial resistance genes and 108 virulence-associated genes were identified among these isolates.

Summary: We analyzed the genomes of 188 bovine-mastitis-causing S. aureus isolates from 65 dairy farms in New Zealand over a 17-year period. The analysis revealed a dominant clonal complex (CC1/ST1) that accounted for 75% of the isolates. This clonal complex showed host adaptation to cattle and exhibited temporal clonal stability.

Summary: Staphylococcus aureus is a major pathogen in humans and livestock, causing serious issues such as bovine mastitis. This study monitored cases of intramammary infection caused by S. aureus in the Miyagi Prefecture, Japan, and analyzed the strains obtained from dairy farms. The study found recurrent cases of infection and identified a Methicillin-Sensitive SA (MSSA) ST398 strain isolated from mastitis-containing cows, which is the first confirmed case in Japan. The results highlight the importance of nationwide surveillance to manage the distribution of ST398 strains in dairy farms for human and animal health.

Summary: This review summarizes the research on bovine Staphylococcus aureus population genetics and molecular pathogenesis conducted worldwide in the past 16 years. It describes the diversity and geographical distribution of S. aureus associated with bovine mastitis, and explores the evolution of bovine S. aureus and the importance of host-adaptation in its emergence as a mastitis pathogen. The functional relevance of virulence determinants in the pathogenesis of bovine mastitis is also discussed.

Summary: Mastitis is a common infectious disease in dairy farms that results in decreased milk production and quality. Staphylococcus aureus is one of the main bacteria causing subclinical mastitis. Exosomes play a role in various physiological and pathological functions by containing proteins, lipids, and nucleic acids.

Summary: Cell death and inflammation are closely linked during mastitis caused by Staphylococcus aureus. Bovine mammary epithelial cells respond to S. aureus by NLRP3 inflammasome activation, leading to cell apoptosis and pyroptosis. This cell death process is associated with caspase-1 activation.

Summary: The formation of biofilms in Staphylococcus aureus strains causing subclinical mastitis in dairy cows is influenced by environmental signals and communication systems, with different staphylococci species impacting S. aureus biofilm formation and dispersion. Specifically, S. chromogenes enhances biofilm formation of an agr-positive S. aureus strain, while NAS isolates suppress biofilm dispersion of S. aureus. Additionally, the effects on biofilm formation and dispersion do not depend on the capacity of NAS to repress the agr system.

Summary: Staphylococcus aureus is a major pathogen causing bovine mastitis, and the development of new antibiotics for veterinary use is important due to its virulence and antibiotic resistance. One such antibiotic, PC206, has been found to have specific narrow-spectrum activity against S. aureus and shows promising results in in vitro and in vivo experiments.

Summary: This study investigates the epigenetic regulation of bovine mammary epithelial cells (bMECs) challenged with Staphylococcus aureus induced by bovine prolactin (bPRL). The results show that bPRL alters specific epigenetic marks, affects the expression of inflammatory genes, and regulates the expression of miRNAs, allowing S. aureus to persist and evade the host immune response.

Summary: This study evaluated three different routes of Streptococcus agalactiae infection in Nile tilapia and found that intraperitoneal and intragastric routes were more aggressive, causing greater brain damage and early mortality, while oral inoculum presented less intensity in brain lesions and a chronic immune response, with longer mortality time. Oral infected-feed administration may be an innovative method for future aquaculture research experiments.

Summary: The fear of COVID-19 and anxiety have a negative impact on physical activity, resulting in a decrease in frequency and intensity of physical activity, a change in the exercise environment, and an increase in sedentary behavior. Individuals who have previously been infected with the virus and those with a low or moderate level of physical activity before the pandemic are more likely to reduce their physical activity.
