Aeromonas infections are the most common bacterial disease of cultured fish in China. In this study, a gram-negative bacillus was isolated from the liver of diseased koi carp (Cyprinus carpio koi), and named strain KC-2. The results of morphological and biochemical tests, as well as phylogenetic analysis derived from 16S rRNA and gyrB sequences indicated that the isolated strain KC-2 was highly...

The author details the connection between disease outbreaks in salmonid fish and imports of salmonid eggs into Japan since the 1950s. The following diseases and species are involved: -infectious pancreatic necrosis in rainbow trout (Oncorhynchus mykiss) -infectious haematopoietic necrosis in sockeye ( of 'kokanee') salmon (O. nerka) and masu salmon (O. masu) -cold water disease, erythrocyte inc...

There are three kinds of uncertainty in the process of fish-disease diagnosis, such as randomicity, fuzzy and imperfection, which affect the veracity of fish-disease diagnostic conclusion. So, it is important to construct a fish-disease diagnostic model to effectively deal with these uncertainty knowledge’s representation and reasoning. In this paper, the well-developed parsimonious covering th...

neurodegenerative disease are characterized by the progressive loss of neurons from specific origins of the cns .alzheimer disease (ad) is a neurodegenerative disorder which affect brain regains that control memory and ability to learn. it is estimated that 27 million people are affected word wide and this number is expected to triple by 2050 due to increase of the population life expectancy. a...

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...

Fluorescence in situ hybridization (FISH) was used to detect 6q-, 11q-, +12, 13q-, 17p- and translocations involving 14q32 in interphase nuclei from blood and/or bone marrow from 113 patients with B-cell chronic lymphocytic leukaemia (B-CLL). A total of 87 patients (77%) had a FISH anomaly: 13q- x 1 was most frequent (64%) followed by 13q- x 2 (28%), +12 (25%), 11q- (15%), 17p- (8%) and 6q- (0%...

The teleost fish has been widely used in creating neurodegenerative models. Here we describe the teleost medaka fish Parkinson's disease (PD) models we developed using toxin treatment and genetic engineering. 1-Methyl-4-phenyl-1,2,3,4-tetrahydropyridine (MPTP), 6-hydroxydopamine (6-OHDA), proteasome inhibitors, lysosome inhibitors and tunicamycin treatment in our model fish replicated some sali...

Fish expert systems have been developed to solve the fish disease diagnosis problems. However, despite these inherent advantages, there are some limitations yet in the application of the systems because of the poor infrastructure and low capacity for the use of computers. A Call Center-based consultant system for fish disease diagnosis has been developed to overcome the difficulties, and the ob...

The practical difficulties in measuring the prevalence, incidence, and pathogenicity of diseases in wild Atlantic salmon populations cause serious problems in determining the possible implications of disease. Limited research has been undertaken on wild salmon disease associated with environmental effects of fish farming, or with the disease implications of possible changes to the genetic make-...
