A Case of thoracic ampiyemia secondary to Serratia rubidaea

Serratia rubidaea is an oportunistic pathogen which is a member of unusual Serratia species.  This is the the first thoracic empyema case report caused by S. rubidaea which is isolated from the pleural fluid of an immunocompetent patient. There is no concensus about the natural habitat of S. rubidaea and the infection was community-based in our case. Here we discussed both the identification and the antibiyogram susceptibility of S. rubideae which needs a special attention hence some common commercial identification systems are lack of carbon utilisation tests. Overlooked laboratory diagnosis and ampric antibiotic treatment may cause life treating infections due to naturally occurring Amp C β-lactamases of unusual Serratia rubideae . Therefore, further studies are needed to identify both the clinical presentation and source of the agent.
