New Delhi Metallo-Β-Lactamase-Producing Carbapenem-Resistant Enterobacteriacae Isolated From Bronchial Washings.

Abstract

The prevalence of Carbapenem resistance among Enterobacteriacae species is increasing and poses a potential major public health risk. In recent years, several new carbapenemases have been identified, including New Delhi metallo-β-lactamase (NDM). A 78-year-old non-smoking female with prior medical history of type 2 diabetes mellitus, gastroesophageal reflux disease (GERD) and prior coronary artery bypass grafting was referred to our respiratory outpatient service for evaluation of a chronic cough and dyspnoea in 2013. Clinical examination revealed bibasal pulmonary crepitations but was otherwise unremarkable. Computed tomography of the chest demonstrated atelectasis of the lingula and right middle lobe. She underwent bronchoscopy, which demonstrated laryngeal mucosa inflammation, consistent with her GERD. There was no growth on bacterial, fungal or mycobacterial bronchial washings cultures.
