Rice-field drowning-associated pneumonia in which Pseudomonas spp., Aspergillus fumigatus, and Cunninghamella sp. Are Isolated

Abstract

We herein report the case of an 84-year-old who developed pneumonia after drowning in a rice field. Besides Aspergillus fumigatus, many pathogens previously not reported in drowning-associated pneumonia (such as Pseudomonas fluorescens, Pseudomonas putida, Nocardia niigatensis, and Cunninghamella sp.) were isolated from his sputum. He received sulbactam/ampicillin, trimethoprim/sulfamethoxazole, voriconazole, levofloxacin and liposomal amphotericin B, but died due to respiratory failure. Because the patient had drowned in a contaminated stagnant rice field and had multiple lung cavities, zygomycosis was suspected. This report provides invaluable information for the consideration of zygomycosis after an individual drowning in a rice field, even in an immunocompetent patient.
