Emerging insights of Staphylococcus spp. in human mastitis.

Human mastitis represents a prevalent and intricate condition that significantly challenges breastfeeding women, often exacerbated by pathogenic bacteria such as Staphylococcus aureus. A deep understanding of the interplay between human mastitis, the breast milk microbiome, and causative agents is imperative. This understanding must focus on the bacterium's virulence and resistance genes, which critically influence the severity and persistence of mastitis. Current methods for detecting these genes, including Polymerase Chain Reaction (PCR), 16S rRNA gene sequencing, shotgun metagenomic sequencing, multiplex PCR, whole genome sequencing (WGS), loop-mediated isothermal amplification (LAMP), CRISPR-based assays, and microarray technology, are vital in elucidating bacterial pathogenicity and resistance profiles. However, advanced attention is required to refine diagnostic techniques, enabling earlier detection and more effective therapeutic approaches for human mastitis. The involvement of Staphylococcus aureus in human infection should be a prime focus, especially in women's health, which deals directly with neonates. Essential virulence genes in Staphylococcus species are instrumental in infection mechanisms and antibiotic resistance, serving as potential targets for personalized treatments. Thus, this review focuses on Staphylococcusaureus-induced mastitis, examining its virulence factors and detection techniques to advance diagnostic and therapeutic strategies.
