Occurrence of Clostridium botulinum type E in shellfish, lake fish and aquatic sediments in the Northwest

Creator:

Hayes, Sidney Joseph

Abstract:

Comparatively little work has been done to determine the ecology of Clostridium botulinum type E since its initial isolation in the nineteen-thirties. This spore forming, anaerobic microorganism is relatively heat labile and has been missed in ecological surveys in which heat was used to selectively screen for spore formers. Use...

Dimethyl disulfide produced in sterile fish muscle by Pseudomonas putrefaciens

Creator:

Rhee, Kie Ho

Abstract:

Sterile fish muscle homogenate was prepared from the individually line caught black rockfish (Sebastes melanops) and inoculated with the pure culture of Pseudomonas putrefaciens strain 17. The inoculated homogenate was incubated at 5°C and the growth and production of volatile sulfur compounds determined by a combined gas-liquid chromatography and mass...

Attachment of the pathogen Flexibacter columnaris to fish cells

Creator:

Zaldivar, Mercedes

Abstract:

The ability of Flexibacter columnaris to attach to fish cells was studied. Four of the five bacterial strains tested were able to adhere to fish cells derived from four different fish species. The attachment of these strains in vitro required magnesium but was not affected by increasing the incubation temperature...
