13. Estudo Etnoveterinário de Plantas Medicinais com Atividade Anti-Helmíntica. / Study of Medicinal Plants with Ethnovet Anthelmintic activity.
A etnoveterinária estuda e valida o conhecimento popular utilizado na atenção e promoção da saúde animal. A fitoterapia, um dos ramos dessa ciência, é cada vez mais utilizada no tratamento de doenças de animais. Dentre as enfermidades que acometem pequenos ruminantes, destacam-se as parasitoses por nematóides gastrintestinais como importante causa

14. Atividade ovicida de dois fármacos em caprinos naturalmente parasitados por nematódeos gastrintestinais, RS, Brasil / Ovicidal activity of two medicaments against goat gastrointestinal nematode in RS, Brazil
A eficácia comparativa entre levamisole em duas doses diferentes e closantel foi avaliada sobre ovos de nematódeos gastrintestinais de caprinos naturalmente parasitados. Observou-se que a redução de ovos de nematódeos gastrintestinais foi de 93,23%, 91,25% e 70,42% nos grupos medicados com levamisole 8mg/kg, levamisole 11mg/kg e closantel 10mg/kg, respe

15. Atividade Anti-helmíntica e imunomoduladora de extratos de Cocos nucifera L. / Anthelmintic activity and immunomodulating extract of Cocos nucifera L.
The development of resistance to synthetic anthelmintic required the search for alternatives for control of gastrointestinal nematodes. Among these, there is the use of medicinal plants. The liquid from the bark of the green coconut (LBGC) was extracted from Cocos nucifera L, followed by obtaining the butanol extract from LBGC. The objectives of this study w

16. Atividade anti-helmíntica de óleos essenciais de Eucalyptus spp sobre nematóides gastrintestinais. / Anthelmintic activity of essential oils of Eucalyptus spp on gastrointestinal nematodes.
O parasitismo por nematóides gastrintestinais representa um dos principais problemas para a produção de ovinos e caprinos. Plantas com atividade anti-helmíntica vêm sendo pesquisadas como uma alternativa de controle destes parasitos. O objetivo deste trabalho foi avaliar a atividade anti-helmíntica dos óleos essenciais de Eucalyptus citriodora (OEEC),

17. Atividade Anti-helmíntica de Cocos nucifera L. Sobre Nematóides Gastrintestinais de Ovinos / Anthelmintic activity of Cocos nucifera L. on Gastrointestinal Nematodes of Sheep
The gastrointestinal nematodes control of small ruminants has been realized by synthetic anthelmintics. However, the development of resistance required research of control alternatives. Among these alternatives is the use of medicinal plants rich in condensed tannins. The objective of this work was to evaluate the efficacy of Cocos nucifera fruit against gas

18. Helminths Control of Chickens utilizing the plants Mentha piperita, Carapa guianensis, Artemisia absinthium and Chenopodium ambrosioides / Controle de helmintos de frangos de corte utilizando as plantas Mentha piperita, Carapa guianensis, Artemisia absinthium e Chenopodium ambrosioides
A hundred chicken of the breeds Rubro negra and Hubbard were necropsied with medium age of 65 days e medium weight of 2 kg. These chickens were utilized for the evaluation of the anthelmintic activity of four species of plants, three cultivated and one native, that can be utilized, in the future, for the control of helminths in an organic production system.

19. Chemical investigation of Spigelia anthelmia Linn. used in Brazilian folk medicine as anthelmintic
An ethanol extract of aerial parts of Spigelia anthelmia was submitted to vacuum column chromatography being eluted with hexane, chloroform, ethyl acetate and methanol. The four extracts were assayed for anthelmintic activity against Haemonchus contortus, the main nematode in caprines. The ethyl acetate extract showed the strongest anthelmintic activity and

20. 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

21. Avermectins, New Family of Potent Anthelmintic Agents: Producing Organism and Fermentation
The avermectins are a complex of chemically related agents which exhibit extraordinarily potent anthelmintic activity. They are produced by a novel species of actinomycete, NRRL 8165, which we have named Streptomyces avermitilis. The morphological and cultural characteristics which differentiate the producing organism from other species are described. The av

22. Development of a mechanism of action-based screen for anthelmintic microbial metabolites with avermectinlike activity and isolation of milbemycin-producing Streptomyces strains.
A high-volume screen for anthelmintic microbial metabolites with an avermectinlike mode of action was developed. The primary screen used the free-living nematode Caenorhabditis elegans in a whole-organism assay. The specificity for avermectinlike compounds resides in the secondary screen, which takes advantage of the chloride channel-opening properties of th

23. Axenomycins, New Cestocidal Antibiotics
Axenomycins are a new group of macrolide antibiotics isolated from the fermentation broth of Streptomyces lisandri n.sp. They exhibit anthelmintic activity against tapeworms (Cestoda). Three different fractions, A, B, and D, have been obtained, the most active fraction being axenomycin D. The activities of the axenomycin complex and axenomycin D against Hyme

24. Antiprotozoal activities of benzimidazoles and correlations with beta-tubulin sequence.
Benzimidazoles have been widely used since the 1960s as anthelmintic agents in veterinary and human medicine and as antifungal agents in agriculture. More recently, selected benzimidazole derivatives were shown to be active in vitro against two protozoan parasites, Trichomonas vaginalis and Giardia lamblia, and clinical studies with AIDS patients have sugges
