This study identifies rsaC, a small non-coding RNA in Staphylococcus aureus, as a virulence factor essential for pathogenicity in a mouse model and its expression is influenced by oxygen and host stress.

The paper isolates and characterizes a glucose homopolymer from broccoli with immunostimulatory effects in both arthropod and mammalian systems.

This study identifies neutral polysaccharides from broccoli buds as potent immunostimulators, showing stronger activity than acidic polysaccharides in a silkworm muscle contraction assay.

The paper identifies a single amino acid substitution in HepT that alters menaquinone chain length and increases antibiotic sensitivity in S. aureus Smith.

This study identifies 11 S. aureus genes critical for virulence using a silkworm infection model, with nine also affecting virulence in mice.
