AB  - Monogeneans are the parasites mostly found on the body surface and gills of fish 
      and can cause large losses in farmed fish. Some studies demonstrate elevated 
      parasitic levels causing hematological alterations. But few of them relate the 
      effects of parasitism on the hematology and histopathology of native freshwater 
      farmed fish. This study evaluated the host-parasite relationship in pacu 
      (Piaractus mesopotamicus) parasitized by the monogenean Anacanthorus 
      penilabiatus. Hematological and parasitological assessments were obtained in 60 
      fish captured in a fish farm located in Dourados, State of Mato Grosso do Sul, 
      Central Brazil. Fish were analyzed in different categories of parasite number: 
      class I (n=13; 0-200 parasites), class II (n=17; 201-1200 parasites); class III 
      (n=7; 1201-2200 parasites); and class IV (n=23; more than 2200 parasites per 
      host). The highest levels of parasitism caused significant decrease (p<0.05) in 
      the hematocrit, red blood cells (RBC), mean hemoglobin concentration (MCHC) and 
      basophils number. Thrombocytes, mean corpuscular volume (MCV), mean corpuscular 
      hemoglobin concentration (MCHC), monocytes, eosinophils, neutrophils and LG-PAS 
      did not present significant difference among the parasitic levels. In contrast, 
      increased number of total leukocytes and lymphocytes were found in 
      highly-parasitized fish. A positive linear correlation (p<0.01) was found between 
      the amount of parasites and fish weight. Histopathology revealed severe 
      hyperplasia, sub-epithelial edema, fusion of the secondary lamellae, focal and 
      multifocal necrosis in highly parasitized fish.
