<em><strong>Bifidobacterium longum </strong></em><strong>BORI inhibits Pain behavior and chondrocyte death, and attenuates osteoarthritis progression.</strong>

This study was undertaken to improve the understanding and treatment of OA. OA was induced in 7-week-old Wistar rats by intra-articular injection of monosodium iodoacetate (MIA); subsequently, the rats underwent oral administration of <em>Bifidobacterium longum</em> BORI (<em>B.</em> BORI). The effects of <em>B.</em> BORI were examined in chondrocytes and an MIA-induced OA rat model.
