Resumo: Aiming to evaluate the effect of parasitic load of Rondonia rondoni over the condition factor of Pterodoras granulosus. Fifty one specimens of P. granulosus were collected in Paraná River, (Porto Rico/Paraná). To analyze were used: Student’s “t”, to determine if length of hosts males and females were similar; Mann-Whitney test “U”, to determine the effect of sex of host on the intensity of infestion of the parasite; “G” Log-likelihood test, to determine the effect of sex of the host on the prevalence of parasite; coefficient of correlation “r”, to determine the correlation between the length of host and the prevalence of infection; Spearman rank correlation coefficient “rs”, to determine as possible correlation’s between the intensity of infection and the parasitic diversity with the length of the host, and to examine the correlation between the parasitic intensity and the condition factor (K). Based in this results we conclude, that despite of variations in the length, between males and females, the sex does not influence in the intensity and prevalence of infection. However, the intensity of parasites and the prevalence of R. rondoni increased with the length of host being that, the intensity does not affect the condition factor of Pterodoras granulosus, which mean to be in equilibrium with the parasite in this local

Foram necropsiados 51 espécimes de armados, coletados no rio Paraná (Porto Rico/Paraná). Para as análises, utilizaram-se os testes de “t”, de Student, para determinar se o comprimento dos hospedeiros machos e fêmeas eram semelhantes; “U”, de Mann-Whitney, para determinar o efeito do sexo do hospedeiro na intensidade de infecção da espécie de parasito; “G” Log-likelihood, para determinar o efeito do sexo do hospedeiro na prevalência do parasito; coeficiente de correlação (CC) “r”, para determinar a correlação entre o comprimento do hospedeiro e a prevalência de infecção; CC por postos de Spearman “rs”, para determinar as possíveis correlações entre a intensidade de infecção e a diversidade parasitária com o comprimento do hospedeiro e para verificar a correlação entre a intensidade parasitária e o fator de condição (K). Os resultados permitiram concluir que, apesar das variações no comprimento entre machos e fêmeas, o sexo não influencia na intensidade e na prevalência de infecção. Porém a intensidade de parasitismo e a prevalência aumentaram com o incremento do comprimento do hospedeiro, e a intensidade parece não afetar o fator de condição de armado, o qual parece estar em equilíbrio com esse parasita nesse ambienteUniversidade Estadual De Maringá2008-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/161310.4025/actascibiolsci.v26i2.1613Acta Scientiarum.
