What is the most common pathogen that causes a Brodie's abscess?

Brodie’s abscess is a localized, subacute osteomyelitis that often arises from hematogenous spread of bacteria to the metaphysis of a long bone. The organism most frequently responsible for osteomyelitis in general, and by far the most common cause of Brodie’s abscess, is Staphylococcus aureus. Its success lies in its ability to invade bone tissue, survive in low-oxygen environments, and form biofilms that help it persist in the area and create a localized abscess. Staphylococcus epidermidis, while a common culprit in infections involving implanted devices, is less likely to be the sole cause of a Brodie’s abscess without hardware. Streptococcus pneumoniae tends to be linked to respiratory infections and meningitis and is not a typical agent for this bone-focused infection. Escherichia coli is more commonly associated with urinary tract infections and intra-abdominal infections, and while it can cause osteomyelitis in certain contexts, it is not the usual offender for Brodie’s abscess. So, the most consistent and frequent cause is Staphylococcus aureus.
