The present study was aimed to reveal whether Ichthyophthiriasis induces plasma parameters alterations in rainbow
trout. Thereby, total sialic acid (TSA), adenosine deaminase (ADA), heat shock protein-27(HSP-27), homocysteine (Hcy),
cholinesterase (CholE) activity level and some blood parameters were studied in suffered ones. After diagnosis of severe
Ichthyophthiriasis, blood samples were collected from seventy infected and same numbers of healthy ones. The results
indicated significant increases (P<0.01) in TSA, Hcy, HSP-27, CholE, MDA, Urea, CREA, AST and TPP in plasma along
with a remarkable decrease in ADA, glucose (GL), catalase(CAT), glutathione peroxidase (GPx), paraoxonase (PON) and
zinc in the infected group compared with healthy ones. In hematology, thrombocytosis, neutrophilia, monocytosis and
eosinophilia along with anemia were clarified in infected group than healthy ones.
The obtained results suggested that Ichthyophthiriasis in rainbow trout develops considerable blood profiles alterations
and some of them may utilize in the part of fish medicine.
