Elderly adults account for >40% of persons with invasive group B streptococcal (GBS) disease and for >50% of GBS-associated deaths in the United States. The prevalence of colonization among healthy elderly adults (∼25%) is similar to that among women of childbearing age. Delineating contributions of comorbid conditions, altered integrity of anatomical barriers, and abnormalities in immune responses caused by immune senescence to pathogenesis require further investigation. Delayed clinical recognition of illness may contribute to poor outcome. Skin and soft-tissue infections and bacteremia with no identified focus are common manifestations of infection in elderly adults and younger nonpregnant adults. Urinary tract infection and pneumonia are presentations more often encountered in elderly persons than in younger adults. The safety and immunogenicity of GBS serotype V—tetanus toxoid conjugate vaccine in healthy elderly persons suggest the potential for vaccination as an approach to prevention of invasive GBS infections in elderly persons.
