Occurrence of Piscirickettsiosis-Like Syndrome in Tilapia in the Continental United States [PDF]
Journal of Veterinary Diagnostic Investigation, 2005 From 2001 to 2003, tilapia ( Oreochromis sp.) farms in Florida, California, and South Carolina experienced epizootics of a systemic disease causing mortality. The fish exhibited lethargy, occasional exophthalmia, and skin petechia. The gills were often necrotic, with a patchy white and red appearance.

Improved understanding of biofilm development by Piscirickettsia salmonis reveals potential risks for the persistence and dissemination of piscirickettsiosis. [PDF]
Sci Rep, 2020 AbstractPiscirickettsia salmonis is the causative agent of piscirickettsiosis, a disease with high socio-economic impacts for Chilean salmonid aquaculture. The identification of major environmental reservoirs for P. salmonis has long been ignored. Most microbial life occurs in biofilms, with possible implications in disease outbreaks as pathogen seed ...

Vaccines for piscirickettsiosis (salmonid rickettsial septicaemia, SRS): the Chile perspective
Expert Review of Vaccines, 2016 Piscirickettsia salmonis (P. salmonis) is the aetiological bacterium of the contagious disease piscirickettsiosis or salmonid rickettsial septicaemia (SRS) and causes significant economic losses to aquaculture production in Chile. Current strategies to control infection are i) indiscriminate antibiotic use and ii) vaccination with predominantly P ...
