Coinfection of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and Bordetella bronchiseptica Pneumonia in a Renal Transplant Patient.

Bordetella species cause respiratory infections in both humans and animals. Bordetella bronchiseptica (B. bronchiseptica) infection is an uncommon pathogen in humans. The clinical spectrum of infections with SARS-CoV-2 includes viral pneumonia of variable severity, with some patients developing acute respiratory distress syndrome (ARDS), requiring mechanical ventilation support. Transplant patients with coronavirus disease (COVID-19) infection have high mortality. Bacterial coinfection, including pneumonia, have been described in patients with COVID-19. We present a renal transplant patient with COVID-19 pneumonia who developed B. bronchiseptica superinfection and had a rapid clinical and radiological response to azithromycin treatment.
