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...
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...
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...
This study aimed to develop a pyriproxyfen-based Rumino-Reticulum Device (RRD) consisting of films poly(vinyl)alcohol (PVA) and sodium carboxymethylcellulose (NaCMC) control the horn fly in cattle, one major pests livestock. Films were obtained by solvent casting method PVA/NaCMC crosslinking presented satisfactory homogeneity, drug content (104.8%) pH (6.5), besides great absorptive capacity with swelling degree 331.40% after 1 hour diffusion-controlled release kinetics (Higuchi). FTIR SEM...
Fipronil (FIP) is an ectoparasiticide of the phenylpyrazole class, used in veterinary medicine topical form. Supported by evidence uncontrolled human exposure to FIP and environmental damage caused commercially available formulations, its use oral administration has become promising. The effectiveness against flea Ctenocephalides felis tick Rhipicephalus sanguineus pharmacokinetics main active metabolite, fipronil sulfone (SULF) were evaluated after single tablets three different doses (2,...
Abstract Background Brazilian spotted fever (BSF), the most lethal tick-borne disease in Western Hemisphere, is caused by bacterium Rickettsia rickettsii and transmitted bite of Amblyomma sculptum . Capybaras are considered primary hosts this tick amplifier R. , generating new infected lineages A. BSF-endemic areas. To define a possible treatment regimen for controlling capybaras, aim study was to establish an effective fluazuron (FLU) dose control larvae artificially infested guinea pigs....
Doxycycline (DOX) is the antibiotic of choice for treatment canine monocytic ehrlichiosis (CME), one main infectious diseases affecting dogs. Despite therapeutic simplicity, need long-term use DOX tablets (28 days) and gastrointestinal effects may pose problems. The aim study was to develop a chewable tablet, evaluate its palatability pharmacokinetic profile in comparison with commercial formulation, Doxifin®, influence co-administration vitamin supplement on bioavailability doxycycline....
O carrapato Ambyomma sculptum, encontrado as várias regiões do Brasil, é conhecido como “carrapato estrela” ou cavalo” e parasita animais domésticos, silvestres humanos, sendo o principal transmissor de Rickettsia rickettsii, agente etiológico da Febre Maculosa Brasileira. Possui grande importância veterinária por causar diversos prejuízos aos seus hospedeiros. Estudos sobre sistema imunológico carrapatos buscam avaliar alterações na resposta celular hemolinfática que faça entender a...
A pulga Ctenocephalides felis (Siphonaptera: Pulicidae) é um inseto parasito de cães e gatos com distribuição cosmopolita. São insetos ápteros, pequenos, coloração castanho-avermelhada, comportamento hematófago na fase adulta, onde aparelho sugador introduzido epiderme, podendo causar irritação pele, espoliação sanguínea e, reações alérgicas. Sua importância saúde pública se destaca por ser vetor diversos agentes patogênicos à animais ao homem. Citrus paradisi (Rutaceae) conhecido...
The aim of the present study was to evaluate hemolymph engorged females Rhipicephalus microplus ticks exposed growth regulator fluazuron. Firstly, were divided into two groups (control and treated) these subjected an immersion test. Hemolymph collected 24 48 hours after test, cellular metabolic response. In comparison with control group, treated group had lower total hemocyte counts at both times, granulocyte higher spherulocyte counts. There reductions in glucose protein values 48-hour...
