ABSTRACT

This study aimed to determine the AR of gastrointestinal nematodes (GIN) to commercial drugs in sheep flocks naturally infected, grazing in irrigated (IA) and dry (DA) areas of the semiarid region in northeastern Brazil. Fecal egg count reduction tests (FECRT) were performed at 10 farms. From each flock, 36 adult sheep were selected and divided into five groups (G1 (0.08% ivermectin), G2 (10% albendazole), G3 (5% levamisole), G4 (1% moxidectin), G5 (10% closantel) and one control group, G6). All the commercial drugs were found to reduce the number of eggs per gram of feces (EPG). Resistance to ivermectin (37.1%), albendazole (52.1%), and levamisole (52.0%) was detected at all the farms, but nematodes proved to be susceptible to moxidectin (87.9%) and closantel (83.9%). The overall average efficacy of the commercial drugs was significantly higher (P < 0.05) in DA (49.2%), where moxidectin (90.4%) showed high effectiveness. The presence of the parasite Haemonchus contortus predominated at all the farms. The variables irrigated area (P = 0.002), intensive breeding (P = 0.018), uncovered enclosures (P = 0.05), cultivated (P = 0.043) and native/cultivated (P = 0.007) pastures, and rotational grazing (P = 0.013) were significantly associated with GIN infection; irrigated area (P = 0.009), semi-intensive breeding (P = 0.05), rotational grazing (P = 0.045), cultivated (P = 0.021) and native/cultivated (P = 0.04) pastures, and estimated weighing of animals (P = 0.002) were significantly associated with AR. Therefore, improved management practices and strategic deworming must be implemented to prevent the development of AR.

ABSTRACT

223 pacientes epiléptico e suas famílias e 136 professores da rede pública e privada foram submetidos a questionários similares que incluíam questöes relacionadas à hereditariedade, transmissibilidade, cura, complicaçöes, cuidados durante as crises, necessidade de informaçöes acerca da doença, Hábitos, comparaçöes com outras doenças e performances sociais e educacionais de epilépticos. Taxas presumidas de cura e complicaçöes representaram a maior diferença entre as duas populacöes. Epilépticos reconhecem um maior número de complicaçöes mas persistem acreditando na cura de sua moléstia. A maioria dos professores e pacientes jamais havia recebido qualquer informaçäo sobre epilepsia e isto possivelmente relacicona-se às respostas equívocas que foram obtidas. Em suma, os dados sugerem que as performances sociais e educacionais de pacientes epilépticos podem ser modificadas por parâmetros médicos e sociais, alguns dos quais podem ser melhorados através de um programa educacional direcionado aos aspectos sociais das epilepsias
