Disease Control
Antimicrobial Compounds Cultures were sensitive to furazolidone, oxolinic
acid, oxytetracycline and potentiated sulphonamides (Austin et al. 1992b ).
Therefore, it is surmised that one or more of these compounds would be useful in
chemotherapy.

Pasteurella skyensis
Characteristics of the Disease
The organism was recovered from four separate incidences of disease among farmed
Atlantic salmon in Scotland during summer over a 4-year period from 1995 to 1998.
The fi sh displayed inappetance (Jones and Cox 1999 ).
