Kitao ( 1985 ) were confi ned to one locality in Japan, there is the likelihood that the

Aliivibrio (= Vibrio) fi scheri
During Autumn 1988, visceral tumours (neoplasia) and skin papillomas were
observed in juvenile turbot, farmed in northwest Spain. Although viral involvement
was suspected, bacteria were evident in the majority of affected fi sh. Most diseased
fi sh possessed whitish nodules on the skin (dorsal surface), haemorrhagic ulceration, and tumours involving the pancreas and bile duct. Within a year, 39 % losses
occurred in the fi sh population (Lamas et al. 1990 ). Bacteria were recovered by use
of TSA supplemented with 2 % (w/v) sodium chloride, marine 2216E agar (Difco)
and TCBS (Oxoid), when virtual pure culture growth of bacteria was recovered
from the kidney and liver, following incubation at an unstated temperature for an
unspecifi ed duration (Lamas et al. 1990 ), and approximated the description of V.
fi scheri, albeit with similarities to V. harveyi (Lamas et al. 1990 ). However, detailed
characteristics of the cultures were not presented. Interestingly, other isolates have
been recovered from gilt-head sea bream, also in Spain (Balebona et al. 1998 ). The
taxon was transferred to a newly created genus Aliivibrio as Ali. fi scheri on the basis
of phylogeny principally involving sequencing of the 16S rRNA gene (Urbanczyk
et al. 2007 ). Chemotherapy was ineffective at reducing mortalities (Lamas et al.
1990 ).
Aliivibrio logei
Characteristics of the Disease
An organism, with similarities to Ali. logei, was associated with shallow skin lesions
of Atlantic salmon farmed in Iceland at low temperatures, i.e. ~10 °C (Benediktsdóttir
et al. 1998 ).
Isolation
Benediktsdóttir et al. ( 1998 ) used 5 % (v/v) horse blood agar supplemented with
1.5 % (w/v) sodium chloride with incubation at 15 °C for 7 days.
