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 ...

Ongoing diversification of the global fish pathogen Piscirickettsia salmonis through genetic isolation and transposition bursts. [PDF]
ISME J, 2023 The management of bacterial pathogens remains a key challenge of aquaculture. The marine gammaproteobacterium Piscirickettsia salmonis is the etiological agent of piscirickettsiosis and causes multi-systemic infections in different salmon species ...

Disease resistance in Atlantic salmon (Salmo salar): coinfection of the intracellular bacterial pathogen Piscirickettsia salmonis and the sea louse Caligus rogercresseyi. [PDF]
PLoS ONE, 2014 BACKGROUND: Naturally occurring coinfections of pathogens have been reported in salmonids, but their consequences on disease resistance are unclear. We hypothesized that 1) coinfection of Caligus rogercresseyi reduces the resistance of Atlantic salmon to

Purification of Piscirickettsia salmonis and associated phage particles [PDF]
Diseases of Aquatic Organisms, 2001 Piscirickettsia salmonis was isolated from cell culture using differential centrifugation and purified on a 30% Percol gradient. The purity of the preparation was assessed by transmission electron microscopy and phage-like particles were found to be associated with some of the P. salmonis isolates examined.

Evidence of the presence of a functional Dot/Icm type IV-B secretion system in the fish bacterial pathogen Piscirickettsia salmonis. [PDF]
PLoS ONE, 2013 Piscirickettsia salmonis is a fish bacterial pathogen that has severely challenged the sustainability of the Chilean salmon industry since its appearance in 1989. As this Gram-negative bacterium has been poorly characterized, relevant aspects of its life

Antigenic characterization of the salmonid pathogen Piscirickettsia salmonis [PDF]
Infection and Immunity, 1996 Piscirickettsia salmonis, the etiological agent of salmonid rickettsial septicemia, was purified from infected immortal chinook salmon (Oncorhynchus tshawytscha) embryo cells by a combination of differential and Percoll density gradient centrifugation. Immune sera from rabbits immunized with purified whole cells of P. salmonis reacted with four protein

Purification of Piscirickettsia salmonis and partial characterization of antigens [PDF]
Diseases of Aquatic Organisms, 1998 Piscirickettsia salmonis is the etiological agent of salmonid rickettsial septicemia, an economically significant disease affecting the salmon aquaculture industry. As with other rickettsial pathogens, antigenic analysis of P. salmonis has been limited by the inherent difficulties of purifying an intracellular organism away from host cell material.

Bacterial networks in Atlantic salmon with Piscirickettsiosis
Scientific Reports, 2023 An unbalanced composition of gut microbiota in fish is hypothesized to play a role in promoting bacterial infections, but the synergistic or antagonistic interactions between bacterial groups in relation to fish health are not well understood.
