Simple adhesive-tape-based sampling of tomato surfaces combined with rapid fluorescence in situ hybridization for Salmonella detection.
نویسندگان
چکیده
A simple adhesive-tape-based method for sampling of tomato surfaces was combined with fluorescence in situ hybridization for rapid culture-independent detection of Salmonella strains. Tapes could also be placed face-down on selective agar for on-tape enrichment of captured Salmonella cells. Overlay of cell-charged tapes with small volumes of liquid enrichment media enabled subsequent detection of tape-captured Salmonella via flow cytometry.

Combination of adhesive-tape-based sampling and fluorescence in situ hybridization for rapid detection of Salmonella on fresh produce.
This protocol describes a simple approach for adhesive-tape-based sampling of tomato and other fresh produce surfaces, followed by on-tape fluorescence in situ hybridization (FISH) for rapid culture-independent detection of Salmonella spp. Cell-charged tapes can also be placed face-down on selective agar for solid-phase enrichment prior to detection. Alternatively, low-volume liquid enrichments...
متن کاملDetection of abl/bcr Fusion Gene in Patients Affected by Chronic Myeloid Leukaemia by Dual-Colour Interphase Fluorescence in situ Hybridisation
Conventional cytogenetic is the standard technique for detection of Philadelphia (Ph) chromosome in chronic myeloid leukemia (CML). Evaluation of abelson murine leukemia/breakpoint cluster region (abl/bcr) fusion using dual-colour fluorescence in situ hybridization (D-FISH) is an alternative approach allowing rapid and reliable detection of the disease. We employed the technique of interphase D...
متن کاملRetrospective assessment of radiation dose by Fluorescence In Situ Hybridization and evaluation of stable chromosomal aberrations
Estimation of absorbed dose for radiation workers or person involved in different radiological accident is the aim of biodosimetry. Cytogenetic methods are the most current and applicable biodosimetry tools. In chronic or protracted exposure, fluorescence in situ hybridization (FISH), stable chromosomal aberration is used for estimation of absorbed dose. For precise estimation of absorbed dose,...

a:4:{s:10:"Background";s:431:"Parental anxiety while waiting for the results of amniocentesis has been investigated by many authors. It seems that the implementation of faster techniques such as fluorescence in-situ hybridization (FISH) will have some benefits in reducing this anxiety. Besides the patients' attitudes to choosing this method, gynecologists who are the persons responsible for tre...
متن کاملEvaluation of a fluorescence-labelled oligonucleotide probe targeting 23S rRNA for in situ detection of Salmonella serovars in paraffin-embedded tissue sections and their rapid identification in bacterial smears.
A method for the detection of Salmonella based on fluorescence in situ hybridization (FISH) has been developed and applied for the direct detection of Salmonella in pure cultures and in formalin-fixed, paraffin-embedded tissue sections. On the basis of the 23S rRNA gene sequences representing all of the S. enterica subspecies and S. bongori, an 18-mer oligonucleotide probe was selected. The spe...
