Enterocloster Clostridioformis Bacteraemia Causing Extensive Mesenteric Venous Thrombosis in a Young Adult: A Case Report

Enterocloster clostridioformis, a recently reclassified anaerobic bacillus, is recognised rarely as a human pathogen in bloodstream and intra-abdominal infections. Vascular complications secondary to such anaerobic sepsis in young, immunocompetent patients are exceptionally rare. Here we present a 27-year-old male chronic alcoholic with prolonged fever, gastrointestinal symptoms and imaging evidence of extensive mesenteric venous thrombosis. Blood cultures grew E. clostridioformis. Treatment with targeted carbapenem antibiotics and prolonged anticoagulation led to full recovery. This report underscores the need for early recognition of anaerobic sepsis-related vascular complications and timely management to achieve favourable outcomes, especially in uncommon presentations linked to chronic alcoholism.
