The antibacterial activity of plant extracts the Lamiaceae family was evaluated against clinical isolates multi-resistant Gram-negative bacteria by broth microdilution technique. Promising results were obtained considering that all active for at least two bacterial species with MIC ranging from 0.5 to 2.0 mg/mL.
Infections caused by multidrug-resistant bacteria are a problem of public health, turning the search for natural products an alternative to antibiotics great importance. The aim this study was investigate in vitro antimicrobial activities Hymenaea courbaril and Stryphnodendron adstringens against bacterial clinical isolates. crude extracts both vegetal species showed bacteriostatic activity almost all evaluated, with minimum inhibitory concentration (MIC) ranging from 125 1250 µg/ml....
Baccharis trimera (Less.) (Asteraceae), popularly know as "carqueja", is a species commonly used in folk medicine for the treatment or prevention of diseases. In this context, purpose work was to study antibacterial activity crude hydroalcoholic extract from against Gram-positive bacterial strains (Staphylococcus aureus ATCC 29213, Staphylococcus saprophyticus 15305, epidermidis 12228, Enterococcus faecalis 19433) and Gram-negative bacteria (Escherichia coli EHEC 43895, Pseudomonas...
The aim of this investigation was to evaluate the phytochemical, antibacterial and cytotoxic activities ethanol extract hexane, dichlorometane, ethyl acetate hydroethanolic fractions from Aristolochia galeata’s rhizomes. minimum inhibitory concentration (MIC) lethal (MLC) were evaluated by broth microdilution assay investigate activity various extracts A. galeata against Gram-positive Gram-negative bacteria. cytotoxicity plant samples in human cervix carcinoma cell line (HeLa)...
Background: The need to identify new antimicrobial drugs that present different mechanisms of action is urgent. variety biological properties chalcones give them a potential therapeutic compounds. Chalcones' synthetic manipulations are investigated worldwide in search more powerful and efficient several infectious diseases' treatment. Objective: purpose this work was evaluate the antibacterial, antifungal, anti-dengue virus (DENV) ten triazole chalcones. Materials Methods: Triazole were used...
Considering the clinical importance of biofilm in medical devices and chronic infections, this study aimed to investigate action polymyxin B on Klebsiella pneumoniae (K. pneumoniae) biofilm. The experiments were performed using a formation assay interaction polysorbate 80 was explored. Both inhibition reduction pre-formed occurred concentration-dependent manner with as high 56 64%, 70 66%, without polysorbate, respectively. addition enhances reduction, but more studies are needed elucidate...
Four novel Cr (III), Co (II) and Ni complexes with 2-thiazoline-2-tiol derivative ligands were synthesized characterized using elemental, physiochemical, spectroscopy analytical methods. The results showed the formation of coordinated by sulfur atoms C = S bond to L1 ligand atom C-S and/or nitrogen intra C-ring L2 ligand. activity against Gram-negative, Gram-positive bacteria yeasts clinical importance was evaluated broth microdilution method. best result obtained L2-Ni compound E. cloacae...
Introdução: Serratia marcescens é considerada causa de infecções em pacientes imunocomprometidos e recém-nascidos o tratamento desafiador, devido a sua resistência intrínseca vários antimicrobianos. É encontrada no solo, plantas água, nesta última antimicrobiana menos estudada. Neste trabalho foi investigada presença susceptibilidade S. água um rio urbano. Material Métodos: Para tal objetivo conduzida uma cultura enriquecida da sob pressão seletiva colistina. Os isolados foram identificados...
The emergence of antibiotic resistance among microbial pathogens is a serious public health problem, resulting in constant need discovering new antibiotics.For this purpose, we synthetized and determined the antimicrobial activity copper (Cu), cobalt (Co), tin (Sn) complexes coordinated with scorpionate ligand tridentate mode against microorganisms clinical importance.New sodium hydrotris(2-mercaptothiazolyl)borate were characterized by physicochemical spectroscopic techniques (UV-vis, IR, 1...
Stryphnodendron adstringens e Hymenaea courbaril são duas espécies vegetais comuns na região do cerrado brasileiro, tradicionalmente empregadas medicina popular). Neste estudo, foi demonstrada a atividade dos extratos hidroetanólicos brutos, obtidos das cascas destas plantas, contra o isolado clínico meticiclina-resistente Staphylococcus aureus (MRSA). A concentração inibitória mínima (CIM) determinada pelo método de microdiluição em caldo (CLSI) fracional (CIF) pela técnica checkerboard...
A prevalência de microorganismos multirresistentes tem aumentado em infecções nosocomiais ,com isso novos antimicrobianos origem vegetal sido utilizado,como o extrato hidroetanólico da Baccharis trimera, conhecida como “carqueja”, uma espécie arbustiva comumente empregada na medicina tradicional. O presente trabalho determinou potencial antimicrobiano do hidroalcoólico bruto Bacharis trimera frente a bactérias Gram-positivas e Gram negativas prevalentes hospitalares. sensibilidade bacteriana...
Resumo: Diante da circulação simultânea de doenças transmitidas pelo Aedes aegypti no Brasil e dos surtos dengue, chikungunya zika, ocorridos 2014 a 2016, torna-se imprescindível intensificação nas ações prevenção conscientização população sobre essas doenças. Nesse sentido, o presente Projeto Extensão teve por objetivo desenvolver atividades combate ao mosquito tema com alunos do Ensino Fundamental II (6º 9º ano). Foram realizados 22 eventos educação em saúde, aproximadamente 1.000 alunos,...
Chalcones highlights as an important structure in medicinal chemistry and thus has been widely used a template the development of new drugs. In this study, we aim to determine antibacterial, anti-Candida, anti-Dengue potential chalcone-bearing 2,4-dihydroxyl tetrahydropyranyl moieties. Antimicrobial activity assays showed that microorganism Staphylococcus genus (including methicillin-resistant strains) were susceptible 2,4-dihydroxychalcones, with minimum inhibitory concentrations (MICs)...
Introduction: Candida albicans is the most common causative agent of Intra-abdominal Candidiasis (IAC) and it resistant to antifungal drugs currently available. Here we investigated atorvastatin in vitro vivo activities against a fluconazole-resistant C. strain as potential repurposed drug. The following tests were carried out: susceptibility determine minimum inhibitory concentration (MIC) fungicidal (MFC), determination time-kill curve, biofilm assays, yeast-hyphae transition inhibition...
A prevalência de microorganismos multirresistentes tem aumentado nas últimas décadas. Diante disso, a prospecção novos antimicrobianos, através compostos químicos sintetizados, representa uma alternativa eficaz no combate às infecções. Portanto, o objetivo deste trabalho foi avaliar atividade antibacteriana dos DT12, PEG e 19 contra bactéria Streptococcus mutans, principal agente causador da cárie dentária outras infecções oportunistas. concentração inibitória mínima (CIM) determinada...
