Pesquisa Veterinária Brasileira 27 (4) 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.

ANTHELMINTIC RESISTANCE IN SMALL RUMINANTS FROM THE SEMIARID OF PARAÍBA STATE, BRAZIL/Resistência anti-helmíntica em pequenos ruminantes do semiárido da Paraíba, Brasil

“…Levamisole Hydrochloride 5% showed reductions of 86.7% and 93% for sheep and goats, respectively, similar to that observed by Rodrigues et al (2007), when tested this anthelmintic in goats from the Sertão region of Paraíba, with 93.3% of efficiency. Duarte et al (2012), testing this anthelmintic in Northern Minas Gerais State, Southeastern Brazil, achieved efficacy ranging from 90% to 100%.…”

Doenças parasitárias em ruminantes no semi-árido brasileiro

“…As perdas econômicas são decorrentes da baixa produtividade, geralmente observada no período seco, e da alta mortalidade, que ocorre principalmente na estação chuvosa (Charles 1989). A importância da hemoncose no semi-árido faz com que as práticas de controle devam ser focadas nesta espécie, levando em consideração as suas características epidemiológicas e o alto risco de seleção de estirpes resistentes, fato já comprovado na região (Athayde et al 1996, Rodrigues et al 2007.…”

Doenças de caprinos diagnosticadas na região Central no Rio Grande do Sul: 114 casos

“…Vários estudos têm sido realizados sobre doenças ou grupos de doenças de caprinos no Brasil (Bandarra et al 2011, Loretti et al 2003, Rodrigues et al 2007, Riet-Correa et al 2008, Medeiros et al 2012. No entanto, há uma carência de estudos abrangentes de todas as doenças diagnosticadas na população caprina com sua respectiva prevalência em determinado estado ou região.…”
