1. 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

2. Metacercárias livres (Digenea: Diplostomidae) em Rhinella fernandezae (Anura: Bufonidae) no sul do Brasil / Free metacercariae (Digenea, Diplostomidae) in Rhinella fernandezae (Anura: Bufonidae) in southern Brazil
Metacercárias livres de uma espécie não determinada de trematódeo digenético (Diplostomidae) foram encontradas nos rins de anuros da espécie Rhinella fernandezae coletados no Município de Imbé, Litoral Norte do Rio Grande do Sul, Brasil. Em uma amostra de 90 anuros, as metacercárias apresentaram prevalência de 3,3% e intensidade de infecção de 8,

3. Canaania obesa (Platyhelminthes: Dicrocoeliidae): redescription and new hosts records
The digenetic trematode Canaania obesa Travassos, 1944 (Dicrocoeliidae) was described as a parasite of the bile ducts of the rodent Akodon cursor Winge, 1887 (Cricetidae) collected in Santa Teresa, state of Espírito Santo, Brazil. In the present study, we report the occurrence of C. obesa infecting three additional sigmodontinae rodent species: Akodon monte

4. Prevalence and pathology of the nematode Heterakis gallinarum, the trematode Paratanaisia bragai, and the protozoan Histomonas meleagridis in the turkey, Meleagris gallopavo
The prevalence of infection and associated pathology induced by two helminth and one protozoan species infecting Brazilian turkeys are reported. The intestinal nematode Heterakis gallinarum appeared with a prevalence of 70% in the infected birds, without gross lesions when not associated to the protozoan Histomonas meleagridis. Histological findings in the c

5. O EFEITO DA PRESSÃO SELETIVA COM PRAZIQUANTEL NA DIVERSIDADE GENÉTICA DA CEPA LE DE Schistosoma mansoni.
Schistosomiasis is one of the parasitic diseases that make a considerable impact upon public health worldwide. In Brazil, it is caused by the digenetic trematode Schistosoma mansoni. The most important schistosomiasis control measure is a large-scale specific chemotherapy. Currently, the drug chosen for schistosomiasis treatment is praziquantel (PZQ). Althou

6. First natural infection by Ascocotyle (Phagicola) longa Ransom (Digenea, Heterophyidae) in an avian host, Ardea cocoi Linnaeus (Aves, Ciconiiformes, Ardeidae) in Brazil
The first case of a natural avian infection caused by the digenetic trematode Ascocotyle (Phagicola) longa Ransom, 1920 in Brazil, is reported from the ardeid bird Ardea cocoi Linnaeus, 1766. This represents a new host record and data on clinical and pathological findings are also reported.

7. Analysis of 16S rRNA and 51-Kilodalton Antigen Gene and Transmission in Mice of Ehrlichia risticii in Virgulate Trematodes from Elimia livescens Snails in Ohio
Operculate snails (the family Pleuroceridae: Elimia livescens) were collected between June and October 1998 from a river in central Ohio where repeated cases of Potomac horse fever (PHF) have occurred. Of collected snails, consistently 50 to 80% carried a combination of cercariae and sporocysts of digenetic virgulate trematodes. The trematodes obtained from

8. A family of fibrinogen-related proteins that precipitates parasite-derived molecules is produced by an invertebrate after infection
After infection with the digenetic trematode Echinostoma paraensei, hemolymph of the snail Biomphalaria glabrata contains lectins comprised of 65-kDa subunits that precipitate polypeptides secreted by E. paraensei intramolluscan larvae. Comparable activity is lacking in hemolymph of uninfected snails. Three different cDNAs with sequence similarities to pepti
