Summary

Group B streptococcal vertebral osteomyelitis is rare in adults. This case in an intravenous drug abuser demonstrates hematogenous spread via bacteremia, likely from needle use.

Background:

Vertebral osteomyelitis caused by Group B Streptococcus (GBS) is uncommon in adults.
Typically, GBS osteomyelitis is linked to contiguous infections, surgery, or vascular disease.
Previous GBS vertebral osteomyelitis cases lacked these risk factors and were presumed hematogenous, but bacteremia was unproven.

Observation:

A 45-year-old individual presented with vertebral osteomyelitis.
The patient was an intravenous drug abuser.
Blood cultures confirmed bacteremia.

Findings:

This case establishes a link between intravenous drug use and GBS vertebral osteomyelitis.
Bacteremia was demonstrated, confirming a hematogenous origin.

Needle use is the most probable source of infection.

Implications:

Highlights intravenous drug use as a significant risk factor for GBS vertebral osteomyelitis.
Suggests a need for increased awareness and screening for GBS infections in intravenous drug users.
Informs diagnostic and treatment strategies for this rare condition.
