Fulminant Streptococcus suis Infection Causing Myocardial Damage and Toxic Shock-Like Syndrome: A Case Report.

There have been no prior reports of direct myocardial damage caused by Streptococcus suis (S. suis), and understanding the clinical course of myocardial involvement is crucial for early diagnosis and initiation of treatment for this infection. A male pig farmer presented as an outpatient with a fever and sore throat, but within hours, his cardiac function declined, and his general condition deteriorated. Despite receiving comprehensive treatment, he succumbed to complications associated with toxic shock-like syndrome (TSLS). Blood cultures identified S. suis, and myocardial pathology revealed the presence of this bacterium in necrotic areas. This case marks the first reported instance of myocardial damage accompanied by TSLS due to S. suis, highlighting the significance of this infection.
