چکیده
We describe a case of pulmonary malacoplakia and Rhodococcus equi cavitary pneumonia in a patient with AIDS. The relationship between Rhodococcus equi, a rare bacterial human pathogen, and malacoplakia, an unusual type of chronic granulomatous inflammation, is discussed.

Malakoplakia is a disease especially of the urinary tract with typical plaques most frequently observed in the urinary bladder's mucosa. In the context of immunosuppression malakoplakia can also occur in other organs. Some of these extravesical malakoplakias are associated with an infection by Rhodococcus equi, a rare human pathogen well known from veterinary medicine. Here we present the first...
متن کاملNon-pulmonary Rhodococcus equi infections in patients with acquired immune deficiency syndrome (AIDS).
Rhodococcus equi, formerly known as Corynebacterium equi, was isolated repeatedly from the blood of two patients with the acquired immune deficiency syndrome (AIDS). Neither of the patients had pneumonia while they were bacteraemic, whereas pneumonia has been present in all previously reported cases of human infection with R equi. One of our patients had diarrhoea and the organism was isolated ...
متن کاملCytokine modulation alters pulmonary clearance of Rhodococcus equi and development of granulomatous pneumonia.
Rhodococcus equi, a facultative intracellular bacterium, causes chronic, often fatal granulomatous pneumonia in young horses and in humans with AIDS. The inability of host alveolar macrophages to kill intracellular R. equi results in the development of granulomas and progressive loss of pulmonary parenchyma. Clearance of the organism from the lung requires functional CD4+ T cells. The purpose o...
متن کاملRhodococcus equi infection: a cause of cavitary pulmonary disease in immuno-compromised patients.
Rhodococcus equi is a facultatively-aerobic, gram-positive and intracellular bacteria that causes pulmonary and disseminated infections in immuno-compromised patients. It is a common agent that causes pneumonia in farm animals and only rarely is transmitted to man. I report a case of pneumonia caused by this agent in a patient with AIDS who had been misdiagnosed as tuberculosis and treated as s...

Rhodococcus equi pneumonia with systemic dissemination is being reported increasingly in immunocompromised patients. This is the first case report of disseminated R equi infection with biopsy documented involvement of the large intestine. The patient was a 46 year old male with AIDS who was diagnosed with cavitating pneumonia involving the left lower lobe. R equi was isolated in culture from th...
