On admission, they had moderate-to-severe dehydration, respiratory distress, pharyngitis, and cervical lymphadenopathy. Abdominal pain and hepatosplenomegaly were inconsistent findings. In addition to the Monospot test, positive adsorption techniques, atypical lymphocytes on peripheral smear, elevated Epstein-Barr virus (EBV) titers, and the patients' clinical presentation were used to make the diagnosis of infectious mononucleosis. Decreased or low normal platelet counts were seen universally. All three patients eventually had positive blood cultures for Fusobacterium species, with two of three patients having Fusobacterium necroformans. We present an additional case of a previously healthy young female with elevated temperature, sore throat, cough, cervical lymphadenopathy, respiratory distress, septic pulmonary
