skyensis Birkbeck et al. 2002.
Gram-negative, pleomorphic cells. Non-motile.
Colonies on TSSBA incubated in air for 48 h at 22 ºC are circular, entire, low, convex,
smooth, grey and 0.5 mm in diameter. Non-haemolytic or weakly haemolytic.
Requires salt (1.5%, w}v) and blood for growth. X and V factors do not permit growth
on blood-free media. Growth occurs at 14-32 °C but not at 37 ºC. Facultatively
Isolated from Atlantic salmon (Salmo salar L.).
Isolated from kidneys of salmons exhibiting symptoms of morbidity and loss of appetite.
