Salmonella is a facultative gram-negative rod which belongs to the Enterobacteriaceae family. In the US, it causes 1.2 million illnesses and 450 deaths each year (1). It usually presents with gastrointestinal complaints, but rarely, it can cause extra-intestinal manifestations. Osteoarticular involvement is unusual, occurring in about 2% of the cases. Septic arthritis is even rarer, involving only 0.2 % of all salmonellosis (2). Endocarditis is another complication which occurs in less than 0.8 % of cases (3, 4). Extra-intestinal complications are more likely to happen among immunocompromised patients. We describe a case of simultaneous right-sided naïve-valve endocarditis and salmonella septic arthritis (SSA) which had been mistaken by brucellosis initially and this delay in treatment caused joint destruction.
