Piscirickettsiosis and Piscirickettsia salmonis in fish: a review
Marco Rozas-Serri, Ricardo Enríquez Abstract The bacterium Piscirickettsia salmonis is the aetio- logical agent of piscirickettsiosis a severe disease that has caused major economic losses in the aquaculture industry since its appearance in 1989. Recent reports of P. salmonis or P. salmonis-like organisms in new fish hosts and geographical regions have increased interest in the bacterium. […]
Epidemiology of Amoebic Gill Disease (AGD) in Chilean salmon industry between 2007 and 2010
Marco Rozas-Serri, Harry Bohle, Horst Grothusen, Patricio Bustos Abstract The recent report of amoebic gill disease (AGD) and of Neoparamoeba perurans in Chile has made it necessary to develop practical tools that will be useful for carrying out epidemiological studies. The prevalence of AGD in Atlantic salmon was 55.7% (29/52 farms) and the epidemic curve was […]
Development of PCR assay for detection of Neoparamoeba perurans and comparison of histological diagnosis
Marco Rozas-Serri, Harry Bohle, Ricardo Ildefonso, Patricio Bustos Abstract The recent description of Amoebic Gill Disease (AGD) and Neoparamoeba perurans in Atlantic salmon (Salmo salar) farmed in Chile has necessitated the development of more reliable and sensitive diagnostic tests. Final diagnosis of infection is normally confirmed by histology. However, the correlation between gross gill lesions […]
Amoebic gill disease (AGD) in Atlantic salmon (Salmo salar) farmed in Chile
Patricio Bustos, Neil Young, Marco Rozas, Harry Bohle, Ricardo Ildefonso, Richard Morrison, Barbara Nowak Abstract Between May and November 2007, three marine Atlantic salmon farms around Chiloé Island, Chile, reported mortalities in which affected fish presented with Caligus rogercresseyi infections and gross gill lesions characteristic of amoebic gill disease (AGD). Histological examination of the gills from affected […]
