Sumario:Alcaligenes faecalis is a gram-negative bacterium that is commonly found in the environment. This pathogen is usually transmitted in the form of droplets through ventilation equipment and nebulizers, but transmission through direct contact has also been documented in few case reports. This pathogen can cause rare but fatal infections including appendicitis, abscesses, meningitis, bloodstream infection, endocarditis, and post-operative endophthalmitis. Pan drug resistance to all commercially available antibiotics has been emerging globally. We present the case of a 66-year-old male who had respiratory failure along with multiple comorbidities. A large cavitary lesion caused by pan drug-resistant Alcaligenes faecalis was found on chest imaging. Despite the treatment with broad-spectrum antibiotics, the clinical outcome was very poor.
