<i>Pseudomonas chlororaphis</i> as a Fish Pathogen

Pseudomonas anguilliseptica as a pathogen of salmonid fish in Finland

The bacterium Pseudomonas angui1liseptica Wakabayashi & Egusa, originally described as a pathogen of eel in Japan, was isolated from diseased Atlantic salmon Salmo salar, sea trout Salmo trutta, rainbow trout Salmo gairdneri, and whitefish Coregonus sp. in Finland. Biochemical tests showed that the Finnish isolates are similar to the Japanese strains except for the Tween 80 reaction. Serologica...

Fish monocytes as a model for mycobacterial host-pathogen interactions.

Mycobacterium marinum, a relatively rapid-growing fish and human pathogen, has become an important model for the investigation of mycobacterial pathogenesis. M. marinum is closely related to the Mycobacterium tuberculosis complex and causes a disease in fish and amphibians with pathology similar to tuberculosis. We have developed an in vitro model for the study of M. marinum virulence mechanism...

Ichthyophonus, a systemic mesomycetozoan pathogen of fish

Isolation of bacteriophages specific to a fish pathogen, Pseudomonas plecoglossicida, as a candidate for disease control.

Two types of bacteriophage specific to Pseudomonas plecoglossicida, the causative agent of bacterial hemorrhagic ascites disease in cultured ayu fish (Plecoglossus altivelis), were isolated from diseased ayu and the rearing pond water. One type of phage, which formed small plaques, was tentatively classified as a member of the family Myoviridae, and the other type, which formed large plaques, w...

Fish pathogen screening and its influence on the likelihood of accidental pathogen introduction during fish translocations.

Fish translocations are an important tool in fisheries management, yet translocating fish carries the risk of introducing unwanted pathogens. Although pathogen screening can be a useful tool for managing the risk associated with fish translocations, screening cannot eliminate this risk. This paper addresses these problems by demonstrating that two elements must be considered when designing effi...
