Detection of Pneumocystis carinii by the polymerase chain reaction (PCR) may facilitate non-invasive diagnosis of P carinii pneumonia and study of its epidemiology. We have compared the sensitivity and specificity of two PCR methods with those of conventional staining for detection of P carinii in induced sputum, bronchoalveolar lavage fluid (BAL), and… (More)
We evaluated the new MPM medium for the growth of Borrelia burgdorferi. All 18 blood samples from 17 patients with Lyme disease were negative. Growth studies showed that by day 4, most organisms in MPM were not viable. Our results reinforce the use of BSK medium as the primary choice for growing B. burgdorferi.
We compared the efficiencies of activation of the photochemical isopsoralen compound 10 and its resulting amplicon neutralizations under conditions with a UV transilluminator box at room temperature (RT) and a HRI-300 UV photothermal reaction chamber at RT and at 5 degrees C. Our data suggest that use of the HRI-300 reaction chamber at 5 degrees C results… (More)
To evaluate the ability of a mouse monoclonal antibody, 2G2, directed against human Pneumocystis carinii, to detect the organism in clinical specimens, a prospective study of the antibody in an indirect immunofluorescent assay was undertaken. P carinii was rapidly detected in thirteen of fourteen bronchoalveolar lavage specimens positive by toluidine-blue-O… (More)
58-year-old man presented with headache, nausea, vomiting, and gait disturbance. Brain MRI showed meningeal enhancement and herniation. Serum Cryptococcus antigen was positive but spinal fluid antigen and cultures were negative. A cerebellar biopsy revealed nonencapsulated Cryptococcus. He completed antifungal therapy. Serum Cryptococcus antigen titer… (More)
Infections have been commonly implicated in lupus relapses and in some cases as initiating the diagnostic work up of systemic lupus erythematosus (SLE). We describe here the case of a young patient who presented with Pseudomonas aeruginosa bacteremia and was found to have a new diagnosis of SLE. 53% of patients with active SLE and abdominal pain have… (More)
