Abstract

Introduction Lactobacillus catenaformis is a gram positive, anaerobic, non-motile and non-spore forming rod belonging to the Erysipelostrichaceae family. This bacterium was reclassified as Eggerthia catenaformis in 2011 after phylogenetic analysis of its genome. It has been proven that this strain can be a human pathogen and can carry genes related to virulence. Here we describe the clinical case of a patient with a lung empyema caused by Lactobacillus catenaformis. Methodology – Case Report A perfectly healthy 62-year-old Malay man presented with history of fever and productive cough with purulent blood streak sputum for one week. He was brought over to emergency department due to worsening shortness of breath. He was noted to be tachypneic and had significant type 1 respiratory failure. Clinical examination showed decreased right basal breath sound with stony dullness on percussion of right lower zone. Right pleural tapping drained 400 mls mucopurelent fluid. Antibiotic therapy with IV Ceftazidime was immediately initiated. The patient was hospitalized in intensive care unit for 2 days necessitating mechanical ventilation and later transferred to general ward. The outcome was favorable with withdrawal of oxygen after 3 days, regression of right pleural effusion on serial chest x-ray. Results In earliest chest x ray, there is homogenous opacity at the right lower zone, associated with loss of right lung volume and air fluid level seen. It is likely to represent right pleural effusion with collapsed consolidation. Subsequent chest x ray showed improvement of right lung volume. Pleural fluid cultures revealed the presence of Lactobacillus catenaformis. The blood and sputum culture examination were negative. Antibiotic therapy was changed to amoxicillin-clavulanic and metronidazole for a total duration of 6 weeks. Conclusions Lactobacillus catenaformis, or Eggerthia catenaformis is a rare but potentially life-threatening anaerobe that can cause lung empyema. Source control and appropriate antibiotic is paramount.
