Cohabitation of Piscirickettsia salmonis genogroups (LF-89 and EM-90): synergistic effect on growth dynamics [PDF]

Frontiers in Cellular and Infection Microbiology, 2023
Piscirickettsia salmonis, the biological agent of Salmonid Rickettsial Septicemia (SRS), is a facultative intracellular bacterium that can be divided into two genogroups (LF-89 and EM-90) with different virulence levels and patterns.

Production and immune response of recombinant Hsp60 and Hsp70 from the salmon pathogen Piscirickettsia salmonis [PDF]

Biological Research, 2005
We have isolated and sequenced the genes encoding the heat shock proteins 60 (Hsp60) and 70 (Hsp70) of the salmon pathogen Piscirickettsia salmonis. The sequence analysis revealed the expected two open reading frames that encode proteins with calculated ...

Piscirickettsiosis in Farmed Turbot, Scophthalmus maximus. [PDF]

J Fish Dis
ABSTRACT Piscirickettsia salmonis is a well‐established intracellular pathogen of farmed Atlantic salmon around the world. The bacterium has also been detected from a number of other hosts including lumpfish (Cyclopterus lumpus), seabass (Dicentrarchus labrax) and rainbow trout (Oncorhynchus mykiss).

Chemical structure of the carbohydrate backbone of the lipopolysaccharide from Piscirickettsia salmonis

Carbohydrate Research, 2013
Elucidation of the carbohydrate backbone structure of the lipopolysaccharide (LPS) from Piscirickettsia salmonis, the etiological agent of the salmonid rickettsial septicemia, is described. Structural information was established by a combination of monosaccharide and methylation analyses of LPS, and by NMR and mass spectrometries of oligosaccharides ...

BIOINFORMATIC ANALYSIS OF GENOMIC ISLANDS IN WHOLE GENOMES OF PISCIRICKETTSIA SALMONIS STRAINS

Journal of Bioinformatics and Genomics, 2023
Piscirickettsiosis, the cause of great losses in Chilean salmonid population, is produced by Piscirickettsia salmonis. The bacterium has developed resistance to treatments over time, including antibiotics and vaccines, due to a variety of evasive ...
