We present a case of human immunodeficiency virus (HIV) infection complicated by Streptococcus bovis meningitis and bacteremia and severe Strongyloides stercoralis colitis. The association between S. bovis infection and strongyloidiasis has not been described previously. This case highlights the importance of searching for larvae of S. stercoralis as part of the evaluation of the gastrointestinal tract of patients with bacteremia or meningitis due to certain enteric organisms. The role of HIV infection in the development of severe S. stercoralis colitis in association with S. bovis bacteremia and meningitis is unclear.
