The inappropriate use of antimicrobials, along with environmental conditions, can lead to the emergence resistant microorganisms. phytopharmaceuticals and herbal medicines has a positive impact represents promising alternative. Psidium guajava extracts have been widely reported antimicrobial potential; however, studies reporting their activity against bacterial strains are scarce. Because emerging resistance, aim this study was analyze capacity aqueous extract guava leaves wild-type strains....
SUMMARY Extracts and essential oils from plants are important natural sources of pesticides. These compounds considered an alternative to control ectoparasites veterinary importance. Schinus molle , endemic species Brazil, produces a high level oil several other compounds. The aim this work was determinate the chemical composition extracts S. further evaluate activity against eggs adults Ctenocephalides felis felis, predominant flea that infests dogs cats in Brazil. In vitro assay, non-polar...
This paper aims to gather and discuss important information about nonylphenol, such as physical chemistry properties, toxicity analytical methods in various matrices. As a degradation product of ethoxylated alkylphenols, nonylphenol presents higher degree reactivity than its precursor. Due harmful effects on the environment, use production has been banned European Union countries, alongside their precursors. The guide quality drinking water (USEPA) recommends maximum concentration 28 µg L-1...
Abstract Essential oils (EO) have the potential to control ectoparasites, being an alternative use of synthetic products. The essential Baccharis trimera and Mimosa verrucosa were evaluated for lethality, residual efficacy, repellence against ectoparasite Ctenocephalides felis Bouché, toxicity was using Saccharomyces cerevisiae eukaryote model. EOs obtained by steam distillation characterized GC/FID/MS. Mortality at different immature stages among adult fleas measured through in vitro filter...
Essential oil (EO) of Cannabis sativa (C. sativa) was evaluated against the egg, larval, pupal, and adult stages flea Ctenocephalides felis felis. The chemical composition EO determined by gas chromatography with flame ionization mass spectrometry. mainly comprised γ-elemene (16.2%) caryophyllene oxide (14.2%) as major compounds. To evaluate mortality in vitro, filter paper tests were performed at different concentrations. C. showed insecticidal activity (100% highest concentrations) for...
The essential oils (EOs) of Illicium verum and Pelargonium graveolens were evaluated for lethality, inhibition development residual efficacy against the flea Ctenocephalides felis felis. Their chemical composition was characterized by means gas chromatography with a flame ionization mass spectrometry detection. Mortality at different immature stages among adult fleas measured through in vitro filter paper tests concentrations EOs. characterization I. volatile oil showed that E-anethole...
Resumo: O uso de óleos essenciais para o controle ectoparasitos interesse veterinário pode ser uma excelente alternativa aos compostos sintéticos comercializados como forma reduzir os impactos negativos na saúde humana e no meio ambiente.A incidência diferentes espécies carrapatos em locais é resultado das características ambientais do território nacional.Entre as estão Amblyomma sculptum, Rhipicephalus microplus sanguineus.Óleos (OEs) Ocimum sp exibem gama atividades biológicas, inseticida,...
Essential oils (EOs) are considered a new class of ecological products aimed at the control insects for industrial and domestic use; however, there still is lack studies involving fleas. Ctenocephalides felis felis, most observed parasite in dogs cats, associated with several diseases. The aim this study was to evaluate vitro activity, establishment LC50 toxicity EOs from Alpinia zerumbet (Pers.) B. L. Burtt & R. M. Sm, Cinnamomum spp., Laurus nobilis L., Mentha spicata Ocimum gratissimum...
Fipronil is a phenylpyrazole class insecticide. It widely used as an insecticide in agriculture and the control of ectoparasites veterinary medicine. The application fipronil injectable form (subcutaneously) becomes innovation, since there no commercially available preparation containing herein. present study aimed at usage, applied subcutaneously cattle, to Rhipicephalus microplus. assessing criteria research have been construction plasma concentration curve efficacy studies. A method using...
Periodontal disease is considered the main oral cavity disorder in dogs. Essential oils have potential for use prevention and treatment of diseases. The antimicrobial activity Schinus molle L. essential oil (SMEO) has already been reported. Chitosan, a natural product with good biocompatibility biodental applications. In this study, we evaluated vitro SMEO against bacteria associated periodontal dogs, developed physicochemical properties novel chitosan-based buccal delivery system containing...
Plant extracts and essential oils have been showing potential for use as acaricides. Rhipicephalus sanguineus, the brown tick, mainly parasitizes dogs is responsible pathogens transmission. The insecticidal acaricidal activity of oil (EO) Syzygium aromaticum eugenol already reported, however against R. sanguineus lacked. To evaluate S. EO larvae in vitro assays were performed using larval immersion test. Bioassays duplicate, within concentration range 0.078 to 40 mg.mL-1. Mortality...
A fast and efficient method has been developed validated for the determination of fipronil in bovine plasma. Samples were subjected to solid-phase extraction (SPE) followed by reversed phase liquid chromatography (LC) separation, using acetonitrile/water (60:40 v/v) as mobile with a flow rate 1.0 mL/min ultraviolet (UV) detection at 210 nm. Ethiprole was used internal standard (IS). The found be linear over range 5-500 ng/mL (r = 0.999). limit quantitation (LOQ) 5 ng/mL. successfully applied...
With the increasing number of pets in home human-animal relationship is increasingly close and care about control disease growing. Ivermectin (IVM) frequently used because its proven safety. IVM recommended for treatment demodectic scabies prevention heartworm dogs, but informally extremely to Ctenocephalides felis Rhipicephalus sanguineus. The aim this study evaluate use by oral route at 0.6μg/kg dose, against experimental infection these parasites using construction plasma concentration...
EXTRACTION AND PURIFICATION OF SELECTIVES CICLOOXIGENASE-2 NONSTEROIDAL ANTIINFLAMMATORY DRUGS.Celecoxib (CB) and lumiracoxib (LM) are potent COX-2 inhibitors widely marketed for the treatment of rheumatoid arthritis osteoarthritis.Nevertheless, it is difficult to obtain because protected under patents.The aim this work was develop an extraction method drugs, CB LM, in order drug with a purity degree appropriated use research projects.The developed showed be effective both becoming...
Zoonoses are major causes of morbidity and mortality worldwide. Among them, Brazilian Spotted Fever (BSF) is an important one that occurs in some regions South America can be transmitted by the "star tick" Amblyomma sculptum. Application acaricides against larval stage as strategy population control. However, there still a deficiency studies on chemical control A. sculptum present work aims to evaluate vitro acaricidal activity cypermethrin, flumethrin, deltamethrin, fipronil, coumaphos...
