Pathology of Infection
Clinical indications of infection in salmons include lethargy, loss of body mass, darkening of the skin, ascites, exopthalmia and kidney pustules, These symptoms vary from one salmonid species to another, and also depend on life stage of the host.
Internally, infection with C. shasta affects entire digestive tract, liver, gall bladder, spleen, gonads, kidney, heart, gills, and muscle tissues. Infection with C. shasta in adult chinook salmon causes mortality through intestinal perforations and co-occurring bacterial infections.
Cold temperatures and salinity may reduce progress of disease, but do not eliminate infection. Progression of infection and mortality is temperature dependent, with higher temperature increasing disease progression and resulting in quicker mortality.

Famous quotes containing the words pathology and/or infection:
“It is often said that Poland is a country where there is anti-semitism and no Jews, which is pathology in its purest state.”
—Bronislaw Geremek (b. 1932)
“This royal throne of kings, this sceptred isle,
This earth of majesty, this seat of Mars,
This other Eden, demi-paradise,
This fortress built by nature for herself
Against infection and the hand of war,
This happy breed of men, this little world,
This precious stone set in the silver sea,
Which serves it in the office of a wall,
Or as a moat defensive to a house
Against the envy of less happier lands;
This blessèd plot, this earth, this realm, this England.”
—William Shakespeare (1564–1616)
