Title

The effect of acute and sub-acute pathogenicity Lactococosis on hematological parameters and some parameters of innate immune response of infected rainbow trout (Oncorhynchus mykiss)

Pages

  29-38

Abstract

 The aim of this study was to evaluate the symptoms, variation of hematological parameters and some parameters of Innate immune response of rainbow trout (Oncorhynchus mykiss) infected with chronic and acute forms of Lactococcus garvieae. The total of 270 Fish were allocated to three groups included Lactococcus garviaea acute infection, Lactococcus garvieaechronic infection and a control group without infection. Acute group was injected with 80% of LD50 and chronic group was injected with 40% of LD50 via intra peritoneal route. . Blood and tissue (brain, head kidney and spleen) samples were collected from each group (n=6 fish) at 0, 1, 3, 14 and 21 days after treatment. In tissues analyzing, lethargy, exophthalmia, ascites and high mortality were seen. The activity of serum lysozyme and myeloperoxidase significantly (p<0. 05) induced in treatment groups. Results indicated that hematocrit and hemoglobin levels decreased in treatment groups (p<0. 05); white blood cells clearly increased in treatment groups. According to these results, acute infection of rainbow trout with Lactococcus garvieae in comparison to chronic infection cause more variations on hematological and immunological parameters; whoever in chronic group the symptoms and change the noted parameters were documented.
