Neutropenia results in an increased susceptibility to bacterial infections. The degree of risk depends upon the cause and severity of the neutropenia, the underlying medical condition of the patient, and the presence or absence of bone marrow reserves for the production of neutrophils. The most common type of infections seen in neutropenic patients are caused by bacteria normally found on the skin (such as Staphylococcus aureus) or from the gastrointestinal and urinary tract. Fungal infections are also more frequent in patients with neutropenia. The infections may be limited to certain areas of the body (commonly the oral cavity, genital area, and skin) or may spread via the bloodstream to the lungs and other organs in severe, prolonged neutropenia.
