| Resumo: |
Differential white blood cell counts from Schizodon intermedius infested by Lernaea cyprinacea were carried out and compared using the Wilcoxon matched pairs test. The observations were performed in fish infested by 16-77 adult Lernaea, fish with parasitic lesions but without attached crustaceans, and non parasitized fish (control group). The specimens of Schizodon intermedius were obtained from the University of Londrina fish farming facilities. The following leucocytes were observed: lymphocytes, neutrophils, monocytes, basophils, eosinophils and immature leucocytes. Intense lymphocytopenia and neutrophilia were observed in the infested hosts. Consistent increasing of monocyte percentage values occurred in the infested fish. The highest values for immature leucocytes counts were recorded from infested fish specimens.
