Comparative analysis of membrane vesicles from three Piscirickettsia salmonis isolates reveals differences in vesicle characteristics [PDF]

, 2016
Membrane vesicles (MVs) are spherical particles naturally released from the membrane of Gram-negative bacteria. Bacterial MV production is associated with a range of phenotypes including biofilm formation, horizontal gene transfer, toxin delivery ...

Monitoring Piscirickettsia salmonis by denaturant gel electrophoresis and competitive PDAO [PDF]

Diseases of Aquatic Organisms, 2000
Reported strains of Piscirickettsia salmonis, a pathogen of salmonid fishes, were analyzed by amplifying part of the internal transcribed spacer (ITS) of the ribosomal RNA (rRNA) operon followed by denaturing gradient gel electrophoresis (DGGE) of the amplicons.

Routes of entry of Piscirickettsia salmonis in rainbow trout Oncorhynchus mykiss [PDF]

Diseases of Aquatic Organisms, 1999
Since 1989, Piscirickettsia salmonis, the causal agent of piscirickettsiosis, has killed millions of farmed salmonids each year in southern Chile. The portal of entry for the pathogen was investigated by use of selected experimental infections in juvenile rainbow trout (12 g).

A functional ferric uptake regulator (Fur) protein in the fish pathogen Piscirickettsia salmonis [PDF]

, 2016
Piscirickettsia salmonis, a Gram-negative fastidious facultative intracellular pathogen, is the causative agent of the salmonid rickettsial septicemia (SRS). The P. salmonis iron acquisition mechanisms and its molecular regulation are unknown. Iron is an

Piscirickettsiosis in Farmed Turbot, Scophthalmus maximus

Journal of Fish Diseases, Volume 49, Issue 9, September 2026.
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).

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 ...
