| FISH Analysis | <molecular biology, technique> Use of a DNA or RNA probe todetect the presence of the complementaryDNA sequence in cloned bacterial or cultured eukaryotic cells.Also used for locating geneson chromosomes. The process is: Prepare microscope slide with cells in metaphase of mitosis, Treat slide with a weak base. Thus denaturing the DNA. Pour radioactively labelled probe onto the slide. Expose slide to photographic emulsion for a few days or weeks. Develop emulsion. (13 Oct 1997) |

| fish bowl granuloma | Localised nodular skin inflammation (small reddish raised areas of skin) caused by a bacterium called mycobacterium marinum.

The infection can be treated with a variety of antibiotics, including doxycycline, minocycline, clarithromycin, rifampin, and trimethoprim-sulfamethoxazole. Also called swimming pool granuloma.
