| Abstract |
The effect of several stressors in promotion of yersiniosis among farme us d O. niloticwas evaluated. Yersinia infected fish were stressed by low dissolved oxygen ( DO ), increased unionized ammonia ( NH3 ) and different copper levels ( 1 mg / L for 1 month ) at two different temperatures ( 18 0 C & 25 0 C ). Decreased DO and exposure to copper increased mortality and / or morbidity percentages. Yersiniosis affected fish showed acute & subacute forms with establishment of asymptomatic carriers. Skin darkening with or without other septicaemic lesions was the principal clinical abnormalities. High percent of asymptomatic survivors were noticed among excess NH3 exposed fish. After 60 days post infection, all or most of unstressed and stressed survivors were Yersinia carriers. Significant reduction of Hb and total serum protein were observed among unstressed infected fish. All stressors caused acute anaemia with non significant decrease of total protein
