Resumo
Utilizando-se de delineamentos experimentais apropriados, foi avaliada a atividade endectocida de uma nova associação medicamentosa, composta de dois piretróides (Scifenotrina e D-tetrametrina), butóxido de piperonila e ivermectina. Quatro experimentos foram conduzidos para avaliação terapêutica da nova associação, comparativamente à formulações adquiridas no mercado. Para avaliação carrapaticida e pulicida foram conduzidos dois experimentos. No primeiro ensaio, 21 cães naturalmente infestados por Rhipicephalus sanguineus, selecionados por meio de duas contagens consecutivas, foram randomizados e sorteados em três grupos de sete animais cada. No segundo ensaio, 21 cães selecionados foram randomizados e sorteados, também, em três grupos de sete animais cada. Infestações artificiais foram realizadas nos dias -4, -2, 6, 13, 20, 27 e 34 com Ctenocephalides felis felis (100 pulgas) e nos dias -1, 6, 13, 20, 27 e 34 com R. sanguineus (30 carrapatos). Nos dois experimentos a nova formulação foi comparada à associação D-fenotrina 78,125%+ piriproxifen 2,575%. A eficácia sarnicida da nova formulação experimental, comparativamente à selamectina 12%, foi avaliada em 15 cães naturalmente infestados por S. scabiei var. canis. Raspados cutâneos e avaliações clínicas (regressão das lesões de pele) foram realizados, em todos os cães experimentais. Para avaliação anti-helmíntica, 24 cães foram selecionados por meio de exames coprológicos e distribuídos em três grupos de oito animais cada. As contagens de ovos de nematódeos por grama de fezes (OPG) foram realizadas nos dias -3, -2, -1 (seleção dos animais) e 1, 3, 7, 10 e 14 pós-tratamento. A nova formulação experimental foi comparada à Selamectina 12%.Todos os dados foram avaliados estatisticamente, e as inferências devidamente extraídas...
Utilizing of the appropriate experimental design, was evaluated the anti-parasite activity of a new formulation, composed of two piretroids (S-cifenotrin and D-tetrametrin), piperonil butox and ivermectinn. Four experiments had been lead for therapeutical evaluation of the new association, comparativily to the formulation acquired in the market. For the evaluation against ticks and flea, two experiments had been lead. In the first assay, 21 dogs naturally infested by Rhipicephalus sanguineus, selected by means of two consecutive countings, were shuffted and randomly put into three groups of seven animals each. In the second assay, 21 selected dogs were allocated randomly, also, in three groups of seven animals each. Artificial infestations had been carried through in days -4, -2, 6, 13, 20, 27 and 34 with Ctenocephalides felis felis (100 fleas) and in days -1, 6, 13, 20, 27 and 34 with R. sanguineus (30 ticks). In the two experiments the new formulation was compared with the association D-fenotrin 78.125%+ piriproxifen 2.575%. The scabies effectiveness of the new experimental formulation, comparativily to selamectin 12%, was evaluated in 15 dogs naturally infested by S. scabiei var. canis. Cutaneous scrapings and clinical evaluations (regression of the skin injuries) had been carried through, in all the experimental dogs. For antihelmintic evaluation, 24 dogs had been selected by means of the coprology examinations and distributed in three groups of eight animals each. The egg countings of nematodes for gram of fezes (EPG) had been carried through in days -3, -2, -1 (election of the animals) and 1, 3, 7, 10 and 14 post-treatment. The new experimental formulation was compared with the selamectina 12%...(Complete abstract, acess undermentioned eletronic address)
