1. Revalidation of Saccocoelioides bacilliformis (Digenea, Haploporidae) parasitizing species of Astyanax (Characiformes, Characidae) from southern Brazil
RESUMO Na Argentina, Saccocoelioides bacilliformis Szidat, 1973 foi descrita a partir de espécimes coletados provavelmente de Astyanax bimaculatus (Linnaeus, 1758), mas posteriormente foi sinonimizada com Saccocoelioides octavus Szidat, 1970. Durante o exame de trematódeos digenéticos coletados de diferentes espécies de Astyanax Baird & Girard, 1854 no s

2. First report of Diplostomidae metacercariae (Trematoda: Digenea) in African catfish Clarias gariepinus (Siluriformes: Clariidae) in Brazil
Resumo Clarias gariepinus é um peixe do Norte da África do Sul e posteriormente introduzido em diversos países, incluindo o Brasil. O presente estudo teve como objetivo descrever o primeiro relato de metacercárias em C. gariepinus no Brasil. Para tanto, 30 C. gariepinus foram capturados em um lago na cidade de Campos dos Goytacazes, RJ, Brasil. Os peixes

3. Infection by Platynosomum illiciens (= P. fastosum) in domestic cats of Araguaína, Tocantins, northern Brazil
Resumo A platinosomose é uma hepatopatia causada por Platynosomum illiciens(= P. fastosum) (Trematoda: Dicrocoelidae), que ocorre principalmente em felinos domésticos e selvagens de áreas tropicais e subtropicais. O objetivo deste trabalho foi verificar a ocorrência de P. illiciens em gatos domésticos do município de Araguaína, Tocantins, Brasil, por

4. Molecular identification and histological aspects of Renicola sloanei (Digenea: Renicolidae) in Puffinus puffinus (Procellariiformes): a first record
Resumo Renicolídeos são parasitos que habitam túbulos renais e ureteres de aves que se alimentam de moluscos e peixes. Puffinus puffinus, ave marinha migratória, foi registrada como hospedeiro definitivo de Renicola spp. Estudos relacionados com as espécies de renicolídeos e as lesões renais resultantes são importantes para o entendimento das causas

5. Metacercariae of Strigeidae Parasitizing Amphibians of the Chaco Region in Argentina
Abstract: The goal of the present study was to analyze the metacercariae found in adult amphibians collected in the Argentinean Chaco region. A total of 194 frogs, Leptodactylus chaquensis, Leptodactylus latinasus, and Lepidobatrachus laevis was examined for digeneans. Three different larval trematodes of the genus Strigea (Digenea, Strigeidae) were found in

6. Synthesis and biological evaluation of novel imidazolidine derivatives as candidates to schistosomicidal agents
ABSTRACT Introduction: Schistosomiasis is an infectious parasitic disease caused by trematodes of the genus Schistosoma, which threatens at least 258 million people worldwide and its control is dependent on a single drug, praziquantel. The aim of this study was to evaluate the anti-Schistosoma mansoni activity in vitro of novel imidazolidine derivatives.

7. Effect of temperature changes on the cercarial-shedding rate of two trematodes
ABSTRACT Since temperature is a key condition in the initiation of cercarial emergence, the objective of the work reported here was to evaluate the effect of that variable on the shedding of two morphologic and taxonomic types of cercariae. Bioassays were accordingly performed with snails naturally infected with either monostome or pleurolophocercous cercari

8. ANTHELMINTIC ACTIVITY OF CHLOROPHYLLIN AGAINST DIFFERENT LARVAL STAGES OF Fasciola gigantica
Fasciolosis is a food borne zoonosis, caused by the digenetic trematode Fasciola. Freshwater lymnaeid snails are the intermediate host of the trematodes. Chlorophyllin, a semi-synthetic derivative of chlorophyll and its formulations obtained from freeze dried cow urine (FCU) had their toxicity tested against redia and cercaria larvae of F. gigantica. The lar

9. Helminthic Parasites of Chickens (Gallus Domesticus) in Different Regions of São Paulo State, Brazil
Abstract The Brazilian poultry industry is an outstanding national and international agribusiness sector. Among the Brazilian states, São Paulo is the largest producer of commercial eggs and the fourth largest producer and exporter of chicken meat. Alternatively, semi-intensive and/or organic poultry production have also obtained a significant share of the

10. Freshwater gastropods of the Baixada Maranhense Microregion, an endemic area for schistosomiasis in the State of Maranhão, Brazil: I - qualitative study
Introduction: The Baixada Maranhense Microregion currently has the highest prevalence of schistosomiasis in the State of Maranhão, likely because this parasitosis is characterized as an occupational disease, and increased contact with water increases the risk of infection by Schistosoma mansoni. This paper reports the results of the first comprehensive fre

11. Larval trematodes in freshwater gastropods from Mato Grosso, Brazil: diversity and host-parasites relationships
Foi realizado um levantamento de trematódeos em gastrópodes límnicos provenientes da área da Usina Hidrelétrica de Manso e das proximidades com potencial turístico, como a região do Pantanal. Moluscos parasitados foram encontrados em doze dos dezoito municípios investigados e quarenta e uma interações cercária-gastrópode límnico foram observadas

12. A directed approach for the identification of transcripts harbouring the spliced leader sequence and the effect of trans-splicing knockdown in Schistosoma mansoni
Schistosomiasis is a major neglected tropical disease caused by trematodes from the genus Schistosoma. Because schistosomes exhibit a complex life cycle and numerous mechanisms for regulating gene expression, it is believed that spliced leader (SL) trans-splicing could play an important role in the biology of these parasites. The purpose of this study was to
