Connective tissue diseases and infections are amongst the causes for organising pneumonia. However, organising pneumonia preceding other connective tissue disease manifestations is rare. Mycobacterium tuberculosis is rarely associated with organising pneumonia. We report such a case. A 50-year-old diabetic male, a roadside shop keeper, a current smoker presented with fever, breathlessness, cough and weight loss for four months. Chest radiography demonstrated areas of consolidation with halo signs. Anti-nuclear antibody blot was positive for Scl-70 and Jo-1 suggestive of a syndrome of systemic sclerosis and polymyositis overlap. Fibre-optic bronchoscopy guided lung biopsy was suggestive of organising pneumonia, and broncho-alveolar lavage detected Mycobacterium tuberculosis. Mycobacterium tuberculosis should be investigated as an aetiology of organising pneumonia, as this may occur in unestablished cases of connective tissue disease even before clinical and radiological manifestations appear, as response can be achieved with anti-tuberculosis therapy alone, without additional use of systemic steroids.

Sphingobacterium species are ubiquitous and are abundant in nature and rarely involved in causing human infections. A 62-year-old man presented with recurrent episodes of high fever up to 40 ​°C accompanied by rigors, sweating, and malaise for the past 4 weeks. After a thorough workup, only elevated C-reactive protein with a leucocytosis was evident. Blood culture showed growth of Gram-negative bacilli which was identified as spingobacterium spiritivorum. Although S. spiritivorum is rare, with limited cases reported in the literature, it must be considered as a causative organism in patients with persistent fevers with sepsis., Competing Interests: Conflict of interest None., (Copyright © 2022 Indian Association of Medical Microbiologists.
