We explored the mechanism of the development from sensitivity to resistance to carbapenem in Pseudomonas aeruginosa. Two P. aeruginosa strains were collected during treatment with carbapenem. Strain homology was investigated using pulsed-field gel electrophoresis. Porin oprD2 expression was analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The minimum inhibitory ...
Background: Rapid diagnosis and differentiation of Brucella is of high importance due to the side effects of antibiotics for the treatment of brucellosis. This study aimed to identify and compare PCR-ELISA as a more accurate diagnositc test with other common molecular and serological tests. Methods: ...
Three-dimensional gel electrophoresis (3-DE), which combines agarose gel electrophoresis and isoelectric focusing/SDS-PAGE, was developed to characterize monoclonal proteins (M-proteins). However, the original 3-DE method has not been optimized and its specificity has not been demonstrated. The main goal of this study was to optimize the 3-DE procedure and then compare it with 2-DE. We develope...
Conventional methods for fungal identification in the clinical laboratory rely on morphological andphysiological tests. These tests often need several days or weeks to complete and are frequentlyunspecific. Molecular identification mostly implies sequencing, which is relatively expensive andtime-consuming, as well as impractical for large numbers of isolates. The Rolling CircleAmplification app...
Immunofixation on cellulose acetate has been compared with immunoelectrophoresis on agarose gel. We studied 90 sera containing monoclonal components and 10 containing polyclonal immunoglobulins according to agarose gel screening electrophoresis. Results by the two methods agreed about 80% of the time for monoclonal components in concentrations exceeding 1-2 g/L. Immunofixation appeared more sen...
PURPOSE Mutations in the SOX2 and CHX10 genes have been reported in patients with anophthalmia and/or microphthalmia. In this study, we evaluated 34 anophthalmic/microphthalmic patient DNA samples (two sets of siblings included) for mutations and sequence variants in SOX2 and CHX10. METHODS Conformational sensitive gel electrophoresis (CSGE) was used for the initial SOX2 and CHX10 screening o...
BACKGROUND AND OBJECTIVES The aim of the study, funded by the Italian Ministry of Health, was to identify the causative mutation in all known patients with hemophilia B in Italy. DESIGN AND METHODS Overall, 269 patients followed by 25 regional centers were considered in the study; after exclusion of the related individuals, 238 unrelated patients were analyzed (153 with severe, 59 with modera...
A highly sensitive enzyme-linked immunosorbent assay was used for the analysis of serum IgG reactivity against specific immunogenic Treponema pallidum proteins. Outer membrane treponemal proteins purified by preparative SDS-polyacrylamide gel electrophoresis were used as antigenic probes at concentrations as low as 100 ng per ml (5 ng per well in microtitre plates). Detection of anti-treponemal...
PURPOSE The aim of this study was to characterize a representative sample of the Peruvian population suffering open-angle glaucoma (OAG) with respect to the myocilin gene (MYOC) mutations, glaucoma phenotype, and ancestry for future glaucoma risk assessment. METHODS DNA samples from 414 unrelated Peruvian subjects, including 205 open-angle glaucoma cases (10 juvenile glaucoma [JOAG], 19 norma...
