Abstract
We have encountered a case of chest wall abscess caused by Salmonella enterica subsp. enterica serovar Choleraesuis in a healthy person. A 38-year-old man was admitted to our hospital because of fever and painful swelling of the chest. The left chest wall abscess was diagnosed on the basis of physical and imaging findings. At a later date, we made an incision and drained the abscess, which yielded cultures of Salmonella. We requested an outside agency to perform immunoserological diagnostic and InvA gene tests. The immunoserological test identified the pathogen as S. Choleraesuis (0 antigen 7, H antigen c; 1,5) and the InvA gene test revealed positive results. It is extremely rare to detect S. Choleraesuis and other NTS in abscess cultures. Therefore, clinicians are generally unable to identify Salmonella, which could cause a delay in treatment. Salmonella can potentially cause healthcare-associated infection. We need to detect Salmonella quickly in order to control infection and provide appropriate antimicrobial therapy. We must proactively perform blood culture tests because S. Choleraesuis is particularly highly active. Additionally, localized infection by Salmonella is not well recognized among clinicians; therefore, we should provide clinical support including information exchange.
