Resumo: | Forty-two adult specimens of “piava”, Schizodon borellii (Boulenger, 1900), and 42 adult specimens of “curimbatá”, Prochilodus lineatus (Valenciennes, 1836), were captured in the floodplain of the upper Paraná River, PR, Brazil, in February 1994 and in March 1995. The aim of the present research was to verify changes caused by parasitism in the blood profile of the above species. The number of erythrocytes (Er), hematocrit (Ht), hemoglobin rate (Hb), percentage of leukocytes were determined and absolute hematimetric indexes, mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration were calculated. Parasites collected from gills and intestines were processed by routine methods. Nine specimens of S. borellii were infested with Dactylogyridae in the gills showing mean infestation intensity (MII) of 278.3 (1 to 1740) and 16 were infested with Cucullanus pinnai (Nematoda: Cucullanidae) in the intestine (MII = 3.3; 1 to 9). Six other fish were infested with Dactylogyridae (MII = 121.5; 2 to 360) and with C. pinnai (MII = 2.0; 1 to 4). No parasite infestation occurred in eleven fish. With regard to this species, no significant change in leukocytes differential counts or in the red series for parasitized fish was found. Individuals with Dactylogyridae were the only ones with special granulocytic cell and without eosinophils. Ten P. lineatus showed Dactylogyridae in the gills with MII = 86.9 (1 to 239), six were infested with Ergasilidae (MII = 27.5; 1 to 81), just one presented Neoechinorhynchus curemai (Acantocephala: Neoechinorhynchidae) in the intestine, and 25 were not parasitized. Dactylogyridae infestation in gills of this species caused only a decrease in hemoglobin rate. Significant differences occurred in Hb and in lymphocyte, neutrophil and monocyte percentages in fish infested with Ergasilidae. The specimen with N. curemai had low percentage of lymphocytes and a high percentage of neutrophils and monocytes. Relative condition factor (Kn) registered that parasites do not affect significantly the hosts’ condition. |

O objetivo era verificar as alterações no quadro hemático destas espécies causadas por parasitismo. Foram determinados o número de eritrócitos (Er), o hematócrito (Ht), a taxa de hemoglobina (Hb), a porcentagem de leucócitos e calculados os índices hematimétricos absolutos: volume corpuscular médio, hemoglobina corpuscular média e concentração de hemoglobina corpuscular média. Os parasitos foram coletados de brânquias e intestinos e processados por métodos de rotina. Nove espécimes de S. borellii estavam parasitados por Dactylogyridae nas brânquias, com intensidade média de infestação(IMI)=278,3 (1 a 1740) e 16 apresentavam Cucullanus pinnai (Nematoda: Cucullanidae) no intestino, com IMI=3,3 (1 a 9). Outros 6 peixes estavam parasitados por Dactylogyridae com IMI=121,5 (2 a 360) e C. pinnai com IMI=2,0 (1 a 4). Onze peixes não apresentaram nenhuma infestação parasitária. Para esta espécie não foi encontrada nenhuma alteração significativa na contagem diferencial dos leucócitos ou na série vermelha, para os peixes parasitados. Os indivíduos com Dactylogyridae foram os únicos que apresentaram célula granulocítica especial e não tinham eosinófilos. Dez espécimens de P. lineatus apresentaram Dactylogyridae nas brânquias com IMI=86,9 (1 a 239), 6 tinham Ergasilidae com IMI=27,5 (1 a 81), 1 estava com 16 Neoechinorhynchus curemai (Acantocephala: Neoechinorhynchidae) no intestino e 25 não estavam parasitados. A infestação por Dactylogyridae nas brânquias desta espécie causou apenas uma diminuição na taxa de hemoglobina. Diferenças significativas foram encontradas em Hb e na porcentagem de linfócitos, neutrófilos e monócitos em peixes infestados por Ergasilidae. No espécime com N. curemai foram observadas baixa porcentagem de linfócitos e altas porcentagens de neutrófilos e monócitos. Através do fator de condição relativo (Kn) verificou-se que os parasitos não afetam de modo significativo a condição dos hospedeiros.Universidade Estadual De Maringá2008-05-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/294010.4025/actascibiolsci.v22i0.2940Acta Scientiarum.
