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 <i>Streptococcus suis (S. suis)</i>, 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 <i>S. suis</i>, 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 <i>S. suis</i>, highlighting the significance of this infection.
