Introduction: Capnocytophaga ochracea is found in the human oral microbiome and a rare cause of antibiotic-resistant, opportunistic septicemia immunocompromised hosts. The zoonotic transmission C from canines to humans has not yet been reported literature. Cohabitation with people associated colonization dogs may be reservoir for infections, which have decreased susceptibility first-line antibiotics commonly used treat animal exposures. Case Report: This case 70-year-old male remote history lymphoma status post splenectomy, remission, who presented stigmata after dog bite, included purpura fulminans on physical examination. Initial broad-spectrum coverage cefepime failed slow progression into multiorgan failure. A strain extended resistance was suspected. Antibiotics were transitioned meropenem, patient eventually made good recovery. Blood cultures isolated ochracea. Conclusion: infections should suspected patients severe sepsis canine exposure. Canine pets species increased antibiotic resistances, such as ochracea, trace their origins microbiome. thorough medical essential identify risk factors asplenia active immune compromise that are antibiotic-resistant strains worse outcomes. For fail initial therapies, cephalosporins avoided because high rates, use carbapenems favored over combination beta-lactam/beta-lactamase inhibitors select clinical scenarios.
