2. Flukicide efficacy against Fasciola hepatica of Triclabendazole and Nitroxynil in cattle of the central valley of Chile
Resumo Em uma fazenda com histórico de fasciolose permanente, foi realizado um estudo com o objetivo de conhecer a eficácia do triclabendazol (TCBZ) e depois contrastar com o do nitroxinil. Trinta e nove bovinos naturalmente infectados com Fasciola hepatica foram distribuídos aleatoriamente em 4 grupos experimentais: Grupo 1 (controle), sem tratamento. O

3. Salvage treatment of disseminated strongyloidiasis in an immunocompromised patient: therapy success with subcutaneous ivermectin
Disseminated strongyloidiasis is a disease with high mortality rate, especially in immunocompromised individuals. Paralytic ileus and intestinal malabsorption are frequent symptoms caused by this severe disease. As there are no licensed parenteral anthelmintic drugs for human use, off-label formulations are often used in the treatment of this disease. In thi

4. Otimização de metodologia qualitativa e quantitativa para identificação de fármacos anti-helmínticos / Qualitative and quantitative method optimization for the identification of anthelmintic drugs
Fármacos benzimidazólicos nas concentrações de 0,375-1,500 μg, foram caracterizados por cromatografia em camada delgada, em dois diferentes sistemas e detectados por luz ultravioleta e vapores de iodo. Este método mostrou-se reprodutível e rápido para identificar e distinguir os seguintes fármacos: albendazol, mebendazol, cambendazol, sulfóxido de

5. Drug trials for treatment of human angiostrongyliasis / Ensaios com drogas para o tratamento da angiostrongilíase humana
Angiostrongilíase abdominal e cerebral são duas infecções importantes produzidas por metastrongilídeos, a primeira delas ocorrendo nas Américas Central e do Sul e a segunda, na Ásia e Ilhas do Pacífico. O tratamento é complicado pelo fato das larvas e vermes adultos viverem e migrarem dentro dos vasos sanguíneos, sendo que as lesões podem se agrav

6. Resistência anti-helmíntica em caprinos no município de Mossoró-rn / Anthelmintic resistance in goats in Mossoró-rn
For many centuries the Brazilian Northeast area is vocation in the production of goats, in the which the gastrointestinal nematodes is among the largest problems. Even with the appearance of anthelmintic drugs of wide action spectrum, the control of the parasites has been harmed by the anthelmintic resistance. The purpose of this study was to verify the sens

7. Impacto del tratamiento en masa a largo plazo con ivermectina en la infección por geohelmintos en el nroeste de Ecuador.
Background: Control of soil-transmitted helminth (STH) infections relies on the periodic and long-term administration of anthelmintic drugs to high-risk groups, particularly school-age children living in endemic areas. There are limited data on the effectiveness of long-term periodic anthelmintic treatment on the prevalence of STHs, particularly from operati

8. Desenvolvimento, avaliação e aplicações de novas fases para extração por sorção em barra de agitação (SBSE) / Development, evaluation and applications of new phases for stir bar sorptive extraction (SBSE)
The development of different kinds of bars for stir bar sorptive extraction (SBSE) was described in this work. This technique has been applied for the extraction of organic compounds from aqueous matrices due to their sorption on the stir bar. Stir bars are composed of a magneto inserted into a glass tube and coated with a polydimethylsiloxane (PDMS) layer.

9. Estudo da inclusão molecular de produtos de interesse farmacologico utilizando ciclodextrinas
Praziquantel is a potent anthelmintic orally. It has a low aqueous solubility (40mg/ 100ml at 25°C), posing problems in the development of a suitable oral formulation and in the biovailabity of these formulations. In order to solve this difficulities, the microencapsulation with cyclodextrin, named molecular inclusion appeared as a suitable solution as cycl

10. An anthelmintic compound, nafuredin, shows selective inhibition of complex I in helminth mitochondria
Infections with parasitic helminths are important causes of morbidity and mortality worldwide. New drugs that are parasite specific and minimally toxic to the host are needed to counter these infections effectively. Here we report the finding of a previously unidentified compound, nafuredin, from Aspergillus niger. Nafuredin inhibits NADH-fumarate reduc

11. Host Movement and the Genetic Structure of Populations of Parasitic Nematodes
Mitochondrial DNA (mtDNA) sequence data were used to compare the population genetic structures of five species of parasitic nematodes from three different hosts: Ostertagia ostertagi and Haemonchus placei from cattle, H. contortus and Teladorsagia circumcincta from sheep, and Mazamastrongylus odocoilei from white-tailed deer. The parasites of sheep and cattl

12. Human microsporidial infections.
Microsporidia are obligate intracellular spore-forming protozoal parasites belonging to the phylum Microspora. Their host range is extensive, including most invertebrates and all classes of vertebrates. More than 100 microsporidial genera and almost 1,000 species have now been identified. Five genera (Enterocytozoon spp., Encephalitozoon spp., Septata spp.,
