RESUMO

The Lippia sidoides Cham (rosemary pepper) is a plant present in part of the semi-arid on Brazil northeastern. Their leaves have shown a high potential in the treatment of dermatitis in humans. This study aimed to evaluate the biological activity of the L. sidoides Cham oil on ectoparasites of domestic dogs (Canis familiares) and antimicrobial activities on Staphylococcus sp. isolated in these animals. To this end, were selected 20 dogs suffering from ectoparasites. In 40 samples of skin culture for bacterial growth it was found positive result in 09 samples analyzed, being Staphylococcus sp isolated, for in vitro evaluation of antimicrobial activity of oil L. sidoides they were subjected to MIC. The results also revealed the presence of flea C. felis felis, tick R. sanguineus. For in vitro evaluation of insecticidal activity against Ctenocephalides felis felis through the filter paper test, were used 150 adult fleas divided into three groups each with ten subjects. G 01 being distilled water + Tween 20, G 02 oil L. sidoides 5% with Tween 20 as a dispersant and G3 three spray fipronil, evaluating motility in time of 10 minutes 1, 3, 6, 12, 24 hours. In the in vivo test 20 pet dogs of both sexes parasitized by C. felis felis were divided into two groups G1 with shampoo of essential oil of L. sidoides 5% and G2 shampoo neutral, bathed twice a week for nine weeks. To in vitro acaricide evaluation against R. sanguineus were used 90 female ticks divided into three treatment groups, being G1 based on essential oil of L. siodoides Cham using Tween 20 as a dispersant at distilled water, G2 cypermethrin + Dichlorvos DDVP and in the negative control G3 distilled water and Tween 20. The results showed significant inhibition of bacterial growth at a concentration of 5% against S. sp. 100% mortality against R. sanguineus in the same concentrations. On in vivo tests against C. felis was a reduction of 100% in the number of fleas treated with L. sidoides and efficacy of 100% in the mortality in vitro of C. felis felis after 24 hours exposure to oil L. sidoides. It was concluded that the essential oil of Lippia sidoides Cham 5% presented insecticide effectiveness on the adult form of Ctenocephalides felis felis in both tests. Well as antimicrobial activity against Staphylococcus spp and acaricide against ticks of R. sanguineus.
