#1 - Gastro-intestinal nematodes control in goats and sheep in the semiarid region northeastern Brazil, 65-71

Abstract in English:

ABSTRACT.- Costa V.M.M., Simões S.V.D & Riet-Correa F. 2011. [Gastro-intestinal nematodes control in goats and sheep in the semiarid region northeastern Brazil.] Controle das parasitoses gastrintestinais em ovinos e caprinos na região semiárida do Nordeste do Brasil. Pesquisa Veterinária Brasileira 31(1):65-71. Hospital Veterinário, Centro de Saúde e Tecnologia Rural, Universidade Federal de Campina Grande, Patos, PB 58700-970, Brazil. E-mail: valery.medeiros@hotmail.com This paper reviews some important concepts to be considered for the control of gastro-intestinal nematode parasites of sheep and goats, including the epidemiology of this parasitic disease in the Brazilian semiarid, and the occurrence of anti-helminthic resistance in the region. Considering the widespread use of preventive treatments during the dry season, new alternatives for the control of gastrointestinal parasites are recommended, taking into account the parasite integrated control system and the use of methods to allow the presence of susceptible parasites in the refugia. Differences between sheep and goats are discussed, taking into account the higher susceptibility of goats and the necessity to use larger doses in goats than in sheep for most anti-helminthics.

RESUMO.- Costa V.M.M., Simões S.V.D & Riet-Correa F. 2011.

E-mail: valery.medeiros@hotmail.com Neste artigo são revisados alguns conceitos importantes a serem considerados para o controle de parasitas gastrintestinais em caprinos e ovinos. Descrevem-se as características epidemiológicas desta parasitose no semiárido e o aparecimento de resistência aos anti-helmínticos na região. São propostas alternativas para o controle da doença levando em consideração, principalmente, a adoção de técnicas de controle integrado de parasitas com uma mudança nos sistemas de tratamento preventivo para sistemas que permitam a sobrevivência de parasitas susceptíveis na refugia. São discutidas as diferenças entre caprinos e ovinos, considerando que os caprinos são mais susceptíveis e que para maioria das drogas devem ser tratados com doses maiores.


#2 - Sensibilidade dos nematóides gastrintestinais de caprinos a anti-helmínticos na mesorregião do sertão paraibano, p.162-166

ABSTRACT.- Rodrigues A.B., Athayde A.C.R., Rodrigues O.G., Silva W.W. & Faria E.B. 2007. [Evaluation of the efficacy of antihelmintics to control gastrointestinal nematodes in goats raised in the state of Paraíba.] Sensibilidade dos nematóides gastrintestinais de caprinos a anti-helmínticos na mesorregião do sertão paraibano. Pesquisa Veterinária Brasileira 27(4):162-166. Curso de Pós-Graduação de Medicina Veterinária em Pequenos Ruminantes, Centro de Saúde e Tecnologia Rural, Universidade Federal de Campina Grande, Campus de Patos, 58700-970 Patos, PB, Brazil. E-mail: adrianabonfimr@yahoo.com.br The objective was to evaluate conventional and alternative anthelminthic action on the sensibility of gastrointestinal nematodes in goats. Hundred and twenty goats of both sexes were distributed into 10 groups of 24 animals each (12 males and 12 females) and submitted to treatments of specific anthelminthic composition. The commercial drugs used were moxidectin 0.2%, albendazole, levamisol chlorhydrate, ivermectin and an aqueous extract of the purgative potato (Operculina hamiltonii). The reduction test was applied through egg counts per gram of feces and larval culture to evaluate resistance. The fecal samples were collected in the day when medication was accomplished (day base), at 7, 14 and 21 days after treatment. The following results for the reduction of Trichostrongyloidea eggs were obtained: Treatment of the females with Moxidectina reduced the egg counts to 92.8, 88.7 and 89.8%, of the males to 92.6, 96.2 and 98.1%; with Levamisol of the females to 96, 97.1 and 91%, of the males to 85.7, 94,2 and 100%; with Albendazol of the females 65, 60.3 and 75.4%, of the males 88.8, 88.8 and 55.5%; with Ivermectin of the females to 92.2, 68.6 and 70.6%, of the males to 41.7, 73.6 and 59.7%; and with the purgative potato of the females to 31.8, 34.1 and 49.4%, of the males to 61.5, 80.7 and 50%. In larval culture Haemonchus, followed by Bunostomum, Trichostrongylus, and Oesophagostomum, were identified even after treatments.
