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 ...

One Health: Piscirickettsia salmonis, salmon overproduction and antimicrobial use and resistance

, 2023
Recent information from Chile suggests the apparent high virulence of Piscirickettsia salmonis in cultured salmonids results from the stress generated by the unhealthily high concentrations at which the fish are grown during production rather than by any

Isolation and Characterization of Serum Extracellular Vesicles (EVs) from Atlantic Salmon Infected with Piscirickettsia Salmonis

Proteomes, 2017
Secretion of extracellular vesicles (EVs) is a common feature of both eukaryotic and prokaryotic cells. Isolated EVs have been shown to contain different types of molecules, including proteins and nucleic acids, and are reported to be key players in ...

Pharmacological iron-chelation as an assisted nutritional immunity strategy against Piscirickettsia salmonis infection

Veterinary Research, 2020
Salmonid Rickettsial Septicaemia (SRS), caused by Piscirickettsia salmonis, is a severe bacterial disease in the Chilean salmon farming industry. Vaccines and antibiotics are the current strategies to fight SRS; however, the high frequency of new ...

Comparative Pan-Genome Analysis of Piscirickettsia salmonis Reveals Genomic Divergences within Genogroups

Frontiers in Cellular and Infection Microbiology, 2017
Piscirickettsia salmonis is the etiological agent of salmonid rickettsial septicemia, a disease that seriously affects the salmonid industry. Despite efforts to genomically characterize P.

Skin Microbiota of Salmonids: A Procedure to Examine Active Bacterial Populations Using an RNA-Based Approach

Applied Microbiology, 2023
Fish microbiota studies have mostly addressed intestinal bacterial communities because of their role in fish physiology; however, the skin microbiota has been studied less despite its role as the first pathogen barrier in the host.

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
