The incidence of S.agalactiae infection in older adults is increasing, especially in those with comorbidities. During the last four decades, invasive infections in adults unrelated to pregnancy have been increasingly reported. In these cases, a frequent underlying cause is osteoarticular or soft-tissue infection.

In older adults, spondilodyscitis should be considered in the Emergency Department (ED) in patients with subacute symptoms of the locomotor system, which may be mistakenly classified as mechanical in origin, until the onset of fever. Lumbar CT for diagnosing spondylodiscititis in the early days of symptoms may not be enough sensitive, so other diagnostic tests such as magnetic resonance imaging or PET-CT with 18F-FDG are useful. In ED, a high index of suspicion is needed since this is a serious and life-threatening disease and potentially fatal disease.
