A case report of wrist arthritis caused by Gemella haemolysans

This case illustrates the potential limits of monotherapy with beta-lactams in native joint infections caused by G. haemolysans, especially in immunocompromised patients. The failure of amoxicillin may be explained by factors such as limited diffusion into joint tissues, the absence of surgical debridement, and the use of pharmacokinetic and pharmacodynamic breakpoints not specifically validated for this rare species. Early reassessment and combination therapy may be warranted, particularly in immunocompromised individuals.
