Bordetella bronchiseptica pneumonia in a patient with a history of pulmonary lymphoma

Bordetella bronchiseptica is an anima pathogenic Gram negative coccobacillus that infrequently causes human infections. Most of the cases recorded in the literature are associated with patients with some type of immunosuppression. In this case, a 67-year-old female patient with a history of pulmonary lymphoma, who received chemotherapy and radiotherapy16 years ago, is admitted to the Internal Medicine Service of the Tomas Casas Casajus Hospital, with a diagnosis of bacterial pneumonia, after ruling out Covid19 infection. A few days later, a B. brochiseptica is isolated from a sputum sample and with the report of the antibiotic sensitivity test, the antibiotic therapy that had originally been indicated is modified, which is reflected in an improvement in the physical state of the patient. However, due to an apparent nosocomial infection, the patient becomes infected with SARS-CO2 and dies due to complications caused by Covid19. (author)
