Chromobacteriosis in a Chinese red panda (Ailurus fulgens styani).
(1/115)
An adult Chinese red panda (Ailurus fulgens styani) transported by airplane from Florida to a North Dakota zoo died 1 week after arrival. Grossly, an interscapular abscess, subcutaneous inflammation, lymphadenitis, and pulmonary abscesses were observed. Microscopic findings included necrotizing inflammation in liver, lung, lymph node, and spleen. Chromobacterium violaceum was cultured from the interscapular abscess, liver, lung, and spleen and was injected into Swiss Webster mice. These mice died 18 hours postinoculation, and C. violaceum was cultured from liver, lung, and spleen. Chromobacterium violaceum is a sporadically reported but highly virulent pathogenic bacterium of both animals and humans typically found as a soil and water inhabitant of tropical and subtropical regions.

Failure to detect circulating Aspergillus markers in a patient with chronic granulomatous disease and invasive aspergillosis.
(2/115)
We report a patient with chronic granulomatous disease who developed invasive pulmonary aspergillosis and a subphrenic abscess. During treatment, high levels of Aspergillus antigen were detected in the abscess, but circulating antigen and Aspergillus DNA were undetectable in the serum. (+info)
Mycobacterium elephantis sp. nov., a rapidly growing non-chromogenic Mycobacterium isolated from an elephant.
(3/115)
A strain isolated from a lung abscess in an elephant that died from chronic respiratory disease was found to have properties consistent with its classification in the genus Mycobacterium. An almost complete sequence of the 165 rDNA of the strain was determined following the cloning and sequencing of the amplified gene. The sequence was aligned with those available on mycobacteria and phylogenetic trees inferred by using three tree-making algorithms. The organism, which formed a distinct phyletic line within the evolutionary radiation occupied by rapidly growing mycobacteria, was readily distinguished from members of validly described species of rapidly growing mycobacteria on the basis of its mycolic acid pattern and by a number of other phenotypic features, notably its ability to grow at higher temperatures. The type strain is Mycobacterium elephantis DSM 44368T. (+info)
Persistent Legionella infection in a patient after bone marrow transplantation.
(4/115)
We report on a patient who developed Legionella pneumonia after bone marrow transplantation. Despite appropriate antibiotic treatment, disease progressed. The patient developed a lung abscess from which Legionella and Prevotella were isolated. Cure was achieved by surgical resection. The resected material was sterile, but 16S ribosomal DNA analysis revealed Legionella DNA. (+info)
Lobectomy for cavitating lung abscess with haemoptysis: strategy for protecting the contralateral lung and also the non-involved lobe of the ipsilateral lung.
(5/115)
We describe the anaesthetic management of a patient undergoing lobectomy for cavitating lung abscess complicated by haemoptysis. Surgery for lung abscess is one of the absolute indications for the use of a double-lumen tube (DLT). Because pus or blood could impede fibreoptic-assisted DLT placement, a traditional, blind placement of the DLT was performed. To protect the uninvolved parts of the operated lung, ventilation of the lung with the abscess was not performed until the resection of the involved lobe had been completed. (+info)
67Gallium in 68 consecutive infection searches.
(6/115)
When employed in the study of peripheral infections, 67Ga scanning is sensitive and accurate. When used as a diagnostic tool for suspected abdominal abscesses, it locates and delineates abscesses in somewhat over half the cases. Moreover, the true-negative rate is high and the false-positive rate is acceptably low. Gallium scans should be interpreted with all available clinical information. The coexistence of noeplasm is a problem which at present is not completely resolved. (+info)
Legionella micdadei lung abscess in a patient with HIV-associated nephropathy.
(7/115)
A patient with end-stage renal disease due to human immunodeficiency-associated nephropathy developed fever, cough and chest pain over a week's duration. He was diagnosed with lung abscess and started on antibiotic coverage. He underwent bronchoscopy because of progression of his illness and persistent fever and bronchoalveolar lavage culture isolated Legionella micdadei. In spite of appropriate antibiotic therapy, the patient remained febrile for 10 days, necessitating chest tube drainage. After a 6-week course of antibiotics and drainage, the patient made an uneventful recovery. Infections due to L. micdadei may be hard to diagnose because of difficulties in isolating this bacteria.

Gallium-67 for the diagnosis and localization of subphrenic abscesses.
(8/115)
Four septic patients with suspected subphrenic abscess were evaluated with gallium-67 citrate and technetium-99m labeled radiopharmaceuticals. Gallium-67 scintigraphs proved instrumental in correctly diagnosing and localizing one left and three right subphrenic abscesses. Gallium-67 scintigraphy can be a useful noninvasive technique for evaluating patients with suspected subphrenic abscess. (+info)
