A specific DNA probe for the identification of Renibacterium salmoninarum, the causative agent of bacterial kidney disease (BKD), was developed from one of 3 clones pRS47, pRS49, and pRS26 of 5.1 kb, 5.3 kb, and 11.3 kb, respectively. The biotinylated pRS47/BamHI insert probe was tested on 3 dilutions of DNA extracted from 3 strains of R. salmoninarum and from 1 strain each of Arthrobacter protophormiae, Aeromonas salmonicida, Corynebacterium aquaticum, Carnobacterium piscicola, Listonella anguillarum, Micrococcus luteus, Pseudomonas fluorescens, Vibrio ordalii, and Yersinia ruckeri. In a dot blot assay, this probe hybridized only with the DNA from the R. salmoninarum strains. When used on kidney samples from fish challenged with R. salmoninarum, the dot blot hybridization assay with the probe was found to be as sensitive as culture. In a fluorescent antibody test, samples that were negative in culture and dot blot hybridization showed no more than one fluorescing cell in 50 microscopic fields examined. This DNA probe, therefore, has the potential for use in the diagnosis of BKD of fish.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D012487 Salmonidae A family of anadromous fish comprising SALMON; TROUT; whitefish; and graylings. They are the most important food and game fishes. Their habitat is the northern Atlantic and Pacific, both marine and inland, and the Great Lakes. (Nelson: Fishes of the World, 1976, p97) Graylings,Thymallus,Whitefish,Salmonids,Grayling,Salmonid
D012680 Sensitivity and Specificity Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed) Specificity,Sensitivity,Specificity and Sensitivity
D013045 Species Specificity The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species. Species Specificities,Specificities, Species,Specificity, Species
D015342 DNA Probes Species- or subspecies-specific DNA (including COMPLEMENTARY DNA; conserved genes, whole chromosomes, or whole genomes) used in hybridization studies in order to identify microorganisms, to measure DNA-DNA homologies, to group subspecies, etc. The DNA probe hybridizes with a specific mRNA, if present. Conventional techniques used for testing for the hybridization product include dot blot assays, Southern blot assays, and DNA:RNA hybrid-specific antibody tests. Conventional labels for the DNA probe include the radioisotope labels 32P and 125I and the chemical label biotin. The use of DNA probes provides a specific, sensitive, rapid, and inexpensive replacement for cell culture techniques for diagnosing infections.
