An Unusual Cause of Neutropenic Fever: Spontaneous Pantoea agglomerans Bacteremia in an Adult. American Journal of Medical Case Reports. 2020; 8(9):289-292. doi: 10.12691/ajmcr-8-9-9


Neutropenia is a serious complication found in immunocompromised patients, particularly those with cancer and human immunodeficiency virus (HIV). The etiology of neutropenia is multifactorial and can be caused by the direct effects of HIV infection, cytotoxic antineoplastic therapy, and malignancy. The main complication of neutropenia is a bloodstream infection caused by gram-positive bacteria (GPB) and gram-negative bacteria (GNB). GPB, specifically S. epidermidis, tend to affect cancer patients more often than GNB. However, GNB such as Pseudomonas aeruginosa have been associated with more serious infections. We report a case of neutropenic fever caused by a GNB, Pantoea agglomerans, in a 47-year-old Afro-Caribbean man with HIV and metastatic salivary adenocarcinoma. Pantoea agglomerans is a non-spore forming rod typically isolated from plants, fruits, and fecal matter, and is rarely pathogenic in humans. In the current literature, cases of P. agglomerans have been documented primarily in the pediatric population secondary to penetrating wound trauma. To our knowledge, this is the first case of spontaneous neutropenic fever secondary to P. agglomerans bacteremia in an Afro-Caribbean adult male.
