Bordetella bronchiseptica pneumonia in a man with acquired immunodeficiency syndrome: a case report

Abstract

IntroductionBordetella bronchiseptica can be a cause of virulent pneumonia in humans with impaired immune systems. Few cases have been reported in the medical literature where Bordetella bronchiseptica has been the only pathogen isolated during a course of interstitial pneumonia.Case presentationA 42-year-old African-American man with human immunodeficiency virus presented with pulmonary symptoms that mimicked Pneumocystis jiroveci pneumonia. A sputum culture grew Bordetella brochiseptica, a common respiratory commensal of wild and domestic animals, rarely implicated in human infections.ConclusionBordetella bronchiseptica should be added to the differential list of pathogens which can affect people with human immunodeficiency virus and pulmonary symptoms. Sputum culture, as well as history of animal exposure, in these patients is advised.

What is New with Bordetella?

“…Bordetella bronchiseptica, an aerobic Gram-negative rod bacteria often associated with mammals, is an infrequent pathogen in immunocompromised subjects causing a variety of respiratory manifestations ranging from sinusitis tracheobronchitis, pneumonia, and septicemia. Of note, our patient did not have any history of close contact with animals [1][2][3][4][5][6][7][8].…”

Rare Tracheobronchitis Agent in a Patient with AIDS: Bordetella bronchiseptica

“…In humans, B. bronchiseptica infection is not common (2). If a human is infected, it is thought that this infection comes from an infected animal with B. bronchiseptica (3). Especially in the young children, in those with underlying disease and in HIV-infected individuals with suppressed immune system, B. bronchiseptica infection has appeared more frequent and severe compared to healthy individuals.…”

Pneumonia caused by Bordetella bronchiseptica in two HIV-positive patients

“…The patient had been in contact with a domestic dog. 9 Wernli et al described eight cases of BB that caused infection or colonization in human beings over a 15-year period. 16 Those researchers showed that seven of their patients had underlying diseases and that only three had been in contact with domestic animals.…”

“…It generally occurs in patients with weak immune systems, such as AIDS patients. [6][7][8][9] Two cases of pneumonia caused by BB in HIV-positive patients at a university hospital are reported below.…”

“…[4][5][6]16 Sputum culturing and investigation of exposure to animals are recommended. 9,16 It became known that the patient in Report 2 had been in contact with 25 domestic dogs. These animals were the potential source of the acquired infection.…”
