Myroides spp and Chryseobacterium spp are uncommon clinical isolates, though more frequently reported to cause infections than other pigmented non-fermentors. Two cases of Myroides odoratus and Chryseobacterium indologenes infection in a diabetic with pulmonary tuberculosis and a patient with de-compensated alcoholic liver disease, respectively, are reported here. Anti-microbial susceptibility testing of the isolates was performed by determining the minimum inhibitory concentration. The clinical picture, characteristic features of the isolates and the antibiotic susceptibility pattern are discussed briefly.

A case of phaeohyphomycosis presenting as multiple subcutaneous abscesses in a young lady with deteriorating liver function was reported here. The lesion started as a solitary abscess in the neck, mimicking tuberculous cold abscess and rapidly involved the face, chest, arms, and legs within six months with ulceration and discharge of thick brownish foul smelling pus. Potassium hydroxide mount of pus from various sites revealed septate dematiaceous hyphae and pseudohyphae. Culture yielded pure growth of Exophiala spinifera. Tissue debridement was done along with initiation of antifungal therapy with ketoconazole. As liver function deteriorated, antifungal therapy was withdrawn after seven days. Patient expired three weeks after admission due to hepatic failure.

Nocardia otitidiscaviarum is a rare cause of pulmonary nocardiosis. We present a case of pulmonary nocardiosis with pleural involvement in an adolescent with rheumatic heart disease and congestive cardiac failure presenting with right lower lobe consolidation and pleural effusion. Direct gram-stain of pleural fluid showed pus cells with Gram-positive filamentous branching bacilli. Empiric treatment with parenteral ceftriaxone and supportive therapy for cardiac failure was initiated. Pleural fluid culture yielded growth of N. otitidiscaviarum at 72 h. Antibiotic susceptibility testing showed resistance to cephalosporins. The patient expired due to congestive cardiac failure on the 5th day.
