These results highlight the protean disease manifestations and antimicrobial susceptibility of Nocardia and indicate the need to address the option of combined antimicrobial therapy for lung and disseminated nocardiosis.

Brain abscesses are occasionally associated with a dental source of infection. An unusual case of frontal lobe abscess in a nonimmunocompromised child infected with multidrug-resistant Capnocytophaga ochracea is described and confirms the pathogenic potential of this organism to cause human disease in the central nervous system.

Pulmonary trichomoniasis is rare, and few cases of trichomonas empyema have been reported in the literature. We describe a rare case of a non-immunocompromised 55-year-old man with Trichomonas empyema presenting with bilateral pleural effusion leading to respiratory failure. Examination of the pleural effusion showed numerous motile organisms by fresh wet preparation that were identified as Trichomonas species by Liu stain. The patient was successfully treated with metronidazole, ampicillin/clavunalate, fibrinolytic therapy, and thoracotomy decortication.
