Fisheries Development Institute (IFOP) researcher Paola Olmos presented studies on fish health at the 8th International Symposium on Aquatic Animal Health held in Charlottetown, Prince Edwards Island, Canada.
The two reports correspond to permanent Programs, executed by professionals and technicians of IFOP Department of Hydrobiological Health, financed by the Ministry of Economy.
The first research work, entitled Antimicrobial susceptibility and classification of Piscirickettsia salmonis isolates from southern Chile, corresponds to the first results obtained from the Bacterial Resistance Surveillance Program in salmon farming, which shows the classification of P. salmonis isolates, according to the results of the Minimum Inhibitory Concentration (MIC) analysis, in the Wild Type (WT) or Non Wild Type (NWT) categories according to the epidemiological cut-off value of the MIC analysis. Conclusion, a high percentage of isolates with reduced susceptibility to Florfenicol is observed.
The second research work, called Infection and horizontal transmission of Piscirickettsia salmonis between sea bass (Eleginops maclovinus) and rainbow trout (Oncorhynchus mykiss) through challenge by cohabitation model, corresponds to one of the results obtained within the Program Evaluation and monitoring of the health status of species wild freshwater and sea, where the horizontal transmission of P. salmonis from sea bass to rainbow trout under controlled conditions is demonstrated for the first time.
Piscirickettsia salmonis is the etiological agent of the Rickettsial Salmon Syndrome (SRS) or Piscirickettsiosis, which produces high mortality in farmed salmon and therefore, a large percentage of both economic and productive losses.
