Cedecea davisae bacteremia in a neutropenic patient with acute myeloid leukemia.

Cedecea are the new members of Enterobacteriacea. Because of their inherent resistance to some antibiotics, the clinical response could be unpredictable making management of Cedecea infection in immunocompromised patients challenging. We report a case of acute myeloid leukemia with central line-related Cedecea bacteremia.

Bordetella bronchiseptica bacteremia in a patient with AIDS.

Bordetella bronchiseptica bacteremia is often associated with various infection in animals. The majority of B bronchiseptica infections reported in humans are cases of pneumonia. Very few cases have been reported in patients with a history of acquired immune deficiency syndrome (AIDS).

Scedosporium apiospermum infection presenting as a pneumothorax and cavitary lung lesions in a patient with acquired immune deficiency syndrome.

The Scedosporium genus consists of filamentous fungi that inhabit soil, sewage, manure, and polluted waters, and contains two medically important species: Scedosporium apiospermum and Scedosporium prolificans. Scedosporiosis is caused by inhalation or traumatic subcutaneous implantation of the organism, and may have varied clinical presentations. A variety of pulmonary manifestations can occur, but to our knowledge, pneumothorax as initial presentation has not been reported.

Cryptococcal meningitis after neurosurgery.

Infection caused by Cryptococcus neoformans can affect a variety of patient populations from the immunocompetent host to those who are severely immunocompromised. Although the clinical presentation can vary, there is a predilection for invasion of the central nervous system. Cryptococcal meningitis is the most common neurologic manifestation.

Lingual leishmaniasis complicating visceral disease.

Leishmania species are obligate intracellular parasites transmitted by various types of female sand flies. The clinical syndrome that results depends on a number of factors including the Leishmania species and immune response of the host. Here, we report successful treatment of lingual leishmaniasis complicating visceral disease in an immunocompetent patient.

Mycobacterium gordonae pulmonary infection in an immunocompetent adult.

Context: Nontuberculous mycobacteria are non-communicable organisms and currently there are over 125 species. Nontuberculous mycobacteria are usually recovered from the environment and can cause disease through respiratory, cutaneous, parenteral and gastrointestinal exposure.

Case Report: We describe a case of a young, immunocompetent patient that developed symptomatic Mycobacterium gordonae pulmonary infection.
