Pasteurella skyensis, Piscirickettsia salmonis, Rickettsia-like organisms,
Streptobacillus, ‘ Candidatus Arthromitus’, ‘ Candidatus Branchiomonas cysticola’,
‘ Candidatus Clavochlamydia salmonicola’, ‘ Candidatus Piscichlamydia salmonis’
and ‘ Candidatus Renichlamydia lutjani’ have been associated with fi sh diseases.
Moritella viscosa has been recovered from winter ulcer disease (= skin lesions) in
Atlantic salmon with pathogenicity mechanisms refl ecting the presence of extracellular products. Protection has been achieved with an adjuvanted formalin inactivated whole cell vaccine. Piscirickettsia salmonis is an obligate parasite, which has
been associated with coho salmon syndrome, Huito disease and salmonid rickettsial
septicaemia. Good protection was recorded by use of a formalised whole cell suspension. ‘ Candidatus ’ are uncultured organisms, which may be visualised in pathological material.
Keywords Epitheliocystis • Winter ulcer disease • Piscirickettsiosis • Red egg
disease • Epizootic ulcerative syndrome
Alteromonadaceae Representatives
Pseudoalteromonas piscicida
Characteristics of the Disease
The organism was associated with whitening of the egg cases, followed by mortalities within 24 h among eggs of damselfi sh, Amphiprion clarkii and Amblyglyphidodon
