The First Reported Case of Bacteremia in a Patient With Human Immunodeficiency Virus Infection.

We describe a case of bacteremia in a human immunodeficiency virus-infected patient caused by a strain lacking 2 major virulence factors, filamentous hemagglutinin and fimbriae. Although bacteremia is uncommon, physicians should be aware that even attenuated strains can cause invasive infection in immunocompromised patients. is a gram-negative coccobacillus that causes a severe paroxysmal coughing disease known as whooping cough or pertussis. colonizes the epithelial cells of the human respiratory tract, and the organisms are typically isolated from nasopharynx. We describe a case of bacteremia in a patient with human immunodeficiency virus (HIV) infection. Interestingly, the isolate recovered from blood culture did not produce the major virulence factors, filamentous hemagglutinin (FHA) and fimbriae (FIM). Previously, 3 cases of bacteremia were reported in the literature. We discuss the features of bacteremia.
