Alcoholics are most likely to have osteomyelitis due to which organism?

In osteomyelitis, the bacteria that cause infection often reflect the patient’s risk factors and how the infection spread. Alcoholism compromises nutrition and immune defenses, which makes hematogenous spread of certain Gram-negative organisms more likely. Klebsiella pneumoniae is classically associated with osteomyelitis in adults with alcohol use because these patients are more prone to bacteremia with this organism and its ability to seed bone during such episodes. While Staphylococcus aureus is the overall most common cause of osteomyelitis, the pattern in alcoholics points toward Klebsiella as a typical culprit. By contrast, Pseudomonas is more tied to intravenous drug use, Salmonella to sickle cell disease, and Staphylococcus aureus remains common but not specifically linked to alcoholism in the same way.
