Effect of aeromonas salmonicida (furunculosis) infection on the incorporation of [1-14C]acetate into lipids of trout liver.
نویسنده
چکیده
[1-(14)C]acetate is incorporated into lipids more rapidly by liver from Aeromonas salmonicida-infected trout than by normal trout liver, both in vitro and in vivo. The increase was, in general, about twofold to less than threefold.

Subunit vaccine candidates against Aeromonas salmonicida in rainbow trout Oncorhynchus mykiss
Aeromonas salmonicida subsp. salmonicida is the etiological agent of furunculosis and a major fish health problem in salmonid aquaculture worldwide. Injection vaccination with commercial mineral oil-adjuvanted bacterin vaccines has been partly successful in preventing the disease but in Danish rainbow trout (Oncorhynchus mykiss, Walbaum) aquaculture furunculosis outbreaks still occur. In this s...
متن کاملTranslocation of viable Aeromonas salmonicida across the intestine of rainbow trout, Oncorhynchus mykiss (Walbaum).
The pathogenic bacterium Aeromonas salmonicida is the causative agent of the destructive disease furunculosis in salmonids. Horizontal transmission in salmonids has been suggested to occur via the skin, gills and/or intestine. Previous reports are contradictory regarding the role of the intestine as a route of infection. The present study therefore investigates the possibility of bacterial tran...
متن کاملBaltic Salmon, Salmo salar, from Swedish River Lule Älv Is More Resistant to Furunculosis Compared to Rainbow Trout
BACKGROUND Furunculosis, caused by Aeromonas salmonicida, continues to be a major health problem for the growing salmonid aquaculture. Despite effective vaccination programs regular outbreaks occur at the fish farms calling for repeated antibiotic treatment. We hypothesized that a difference in natural susceptibility to this disease might exist between Baltic salmon and the widely used rainbow ...
متن کاملA live (delta aroA) Aeromonas salmonicida vaccine for furunculosis preferentially stimulates T-cell responses relative to B-cell responses in rainbow trout (Oncorhynchus mykiss).
We have previously described (L. M. Vaughan, P. R. Smith, and T. J. Foster, Infect. Immun. 61:2172-2181, 1993) the construction of a kanamycin-resistant aromatic-dependent mutant of Aeromonas salmonicida, the causative agent of furunculosis, and its use as a live vaccine. Here we describe the construction of an unmarked aroA deletion mutant and examine the nature and magnitude of immune respons...
متن کاملType III Secretion System of Aeromonas salmonicida Undermining the Host's Immune Response
Aeromonas salmonicida subsp. salmonicida is an important pathogen in salmonid aquaculture and is responsible for furunculosis, a common infectious disease in salmon, trout and char. The type-three secretion system (T3SS) is considered as the major virulence attribute of A. salmonicida. It is used by the bacterium to secrete and translocate a large number of toxins and effector proteins into the...
