ABSTRACT
Objetivou-se identificar os ectoparasitos de animais silvestres recepcionados pelo Centro de Triagem de Animais Silvestres, São Luís, Maranhão. Os ectopararasitos identificados foram: piolhos Acidoproctus sp., Trinoton sp., Ciconiphilus sp, Austromenopon sp., Quadraceps sp., Saemundssonia sp. e Trichodectes canis; carrapato Amblyomma rotundatum e Rhipicephalus sanguineus; pulgas Ctenocephalides felis e larvas de Cochliomyia hominivorax. Os resultados apresentados documentam a infestação de mamíferos, répteis e aves silvestres por ectoparasitos.
The objective of this study was to identify the ectoparasites of wild animals received by the Center of Wild Animals of São Luís, Maranhão, Brazil. The ectoparasites identified were: the lice Acidoproctus sp., Trinoton sp., Ciconiphilus sp., Austromenopon sp., Quadraceps sp., Saemundssonia sp., and Trichodectes canis; the ticks Amblyomma rotundatum and Rhipicephalus sanguineus; the fleas Ctenocephalides felis, and larvae of Cochliomyia hominivorax. The data presented register the infestation of wild mammals, reptiles and birds by ectoparasites.

Knowledge of genotype distribution of hepatitis C virus (HCV) has clinical importance due to genotype 1 lower response to treatment compared with genotypes 2 and 3. The goal of this survey was to describe clinical and laboratorial profiles of patients with chronic hepatitis C (CHC) in the State of Piauí, as well as to expand the overall awareness of the distribution of HCV genotyping in Northeast of Brazil. A retrospective cross-sectional study was carried out between April 1999 and August 2005. A total of 153 patients were included, 119 (77.8 percent) males and 34 (22.2 percent) females; mean age = 48.01 ± 9.11 years. We observed a homogeneous distribution between genotypes 1 (50.0 percent) and 3 (49.0 percent), while the most frequent subtype noticed was 3a (49.0 percent). The mean viral load among patients with subtype 1b (1,232,476 UI/mL) was significantly superior to the subtype 1a (391,204 UI/mL; p = 0.010) and to the subtype 3a (594,228 UI/mL; p = 0.047). The average levels of gamma-glutamiltransferase of genotype 1 (144 mg/dL) had statistical differences when compared to genotype 3 (74 mg/dL; p = 0.014). Most patients showed mild to moderate degrees of histopathological necroinflammatory activity and hepatic fibrosis (79.0 percent and 56.2 percent, respectively). We concluded that most candidates to treatment of CHC in the State of Piauí presented with clinically stable hepatic illness; the distribution of genotypes 1 and 3 was virtually homogeneous; and there was no significant demographic or clinical differences among genotypes or subtypes of HCV.
