Piscirickettsia-Like Organisms as a Cause of Acute Necrotic Lesions in Colombian Tilapia Larvae

Journal of Veterinary Diagnostic Investigation, 2011
Rickettsial organisms are well-known fish pathogens in both natural and culture environments. This study reports an outbreak of disease in red tilapia larvae caused by piscirickettsia-like organisms (PLOs), which lasted from June until October 2009 ...

Improved purification of Piscirickettsia salmonis using Percoll gradients

Journal of Microbiological Methods, 2006
Viable preparations of intact Piscirickettsia salmonis, purified from host cell material, are necessary for studying characteristics associated with this bacterium. However, purification of the organism is difficult due to its obligate intracellular nature. A simple and effective method for isolating whole P.

Modeling the Transmission of Piscirickettsia salmonis in Farmed Salmon

AIP Conference Proceedings, 2007
Farming Atlantic salmon is an economic activity of growing relevance in the southern regions of Chile. The need to increase efficiency and reach production goals, as well as restrictions on the use of water resources, had led in recent years to certain practices that proved prone to bacterial infections among the fish.Our study focuses on the impact of

The Biology and Molecular Detection of Piscirickettsia Salmonis

2002
Piscirickettsia salmonis is an emerging obligate intracellular bacterial pathogen of salmonids (Fryer and Mauel 1997). This Gram-negative pleiomorphic coccoid bacterium replicates within membrane-bound cytoplasmic vacuoles in the cells of infected fish.

Piscirickettsia salmonis, a major pathogen of salmonid fish in Chile

Fisheries Research, 1993
Abstract Piscirickettsiosis has resulted in extensive losses among salmonid fishes cultured in southern Chile. It occurs at many seawater sites near Puerto Montt, where recurring epizootics have frequently resulted in mortality approaching 90% among the coho salmon (Oncorhynchus kisutch) cultured there.

Characterization of a novel and genetically different small infective variant of Piscirickettsia salmonis

Microbial Pathogenesis, 2008
We report a novel genetically different small infective variant of the fish pathogen Piscirickettsia salmonis (sP.s). sP.s variants were recovered both from ageing post-infected CHSE-214 culture cells as well as from naturally infected fish. The ITS region of sP.s variants, although sharing a common core sequence, is different from the ITS of the ...
