Texto completoEnterococci are pathogens with considerable ability to express resistance to multiple antimicrobials and abundant representation in foods. This study aimed to carry out the isolation of strains of the genus Enterococcus in food, represented by chicken and pork (raw and processed), to analyze the profile of antimicrobial resistance by the disk diffusion method and by molecular techniques to identify species isolates and genes encoding resistance to vancomycin and tetracycline. 36 samples, totaling 54 strains belonging to the genus Enterococcus were analyzed. The species detected in most occurred in isolates from raw chicken meat (40 %) and raw pork (29%) was isolated in E. faecalis and processed meat products (100%) E. faecium. E. casseliflavus / E. flavencens had its isolation only in the processed product. The species E. gallinarum was confirmed between food samples surveyed. E. faecalis and E. faecium isolates from raw chicken meat isolated were significantly more resistant than the other samples, showing high percentage of resistance to: streptomycin, ciprofloxacin, norfloxacin, erythromycin, vancomycin and tetracycline. The isolated raw poultry and swine gene showed resistance to tetracycline and vancomycin. Therefore, it is suggested that food of animal origin may play an important role in the dissemination and transfer resistant enterococci and / or resistance genes to humans.

Texto completoSome naturally occurring compounds containing the naphtho [2,3 - c] pyran ring system have been found to be useful antibiotic agents and thus the laboratory synthesis ofthese compounds and their derivatives are of importance in the medical field. Their antibiotic and even antineoplastic activities are attributed to their potential to act as alkylating agents, via a bioreductive process. This thesis deals with studies directed towards the synthesis of some benzo [c] pyrans as these compounds also possess the correct structural configuration to undergo the bioreductive process, and act as alkylating agents to cellular nucleic acids. Chapter Two describes the synthesis 00,4 dihydro - 1,3 - dimethyl- IH - benzo - [cl pyran - 5,8 - quinone (13) by employing a base induced cyclization with potassium tertiary butoxide. This compound was proven to be biologically active against both Gram positive and Gram negative organisms. (±) (1R, 3R, 4R) - 3,4 - Dihydro - 4 - hyroxy -1,3 - dimethyl- 1H - benzo [e] pyran - 5,8quinone (17) and its 4 S diastereomer (18) were synthesized with cerium (IV) ammonium nitrate as the cyclizing reagent. Antimicrobial evaluation ofcompound (17) displayed inhibitory activity against both Gram positive and Gram negative organism growth. This is discussed in Chapter Three. In Chapter Four, the synthesis ofthe benzo analogue ofthe naturally occurring naphthopyran antibiotic, hongconin, is discussed. The synthetic route used for this synthesis could well be applied to synthesise hongconin.

Resumo: As indústrias cosméticas e farmacêuticas têm um crescente interesse na substituição dos antimicrobianos sintéticos nos produtos dermatológicos, devido à resistência dos microrganismos aos antimicrobianos convencionais. O pequi (Caryocar brasiliense Camb) é uma frutífera nativa do Cerrado brasileiro utilizada na medicina popular, na indústria cosmética e na alimentação, com atividades leishmanicida e antimicrobiana descritas na literatura. O objetivo principal deste trabalho foi avaliar a segurança e a eficácia do extrato de Caryocar brasilense obtido por CO2 supercrítico visando sua aplicação cosmética. A concentração inibitória mínima (CIM) frente às bactérias Escherichia coli, Pseudomonas aeruginosa e Staphylococcus aureus foi determinada pelo método clássico de microdiluição em placas. O potencial antioxidante do extrato foi determinado por um método baseado na oxidação do 2,2-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS). Para avaliação da citotoxicidade e fototoxicidade in vitro, foram utilizados métodos colorimétricos baseados na conversão do corante tetrazólio (XTT) e o método do vermelho neutro (3T3 NRU), respectivamente. Na avaliação do potencial de irritação ocular empregou-se o teste na membrana corioalantóide do ovo de galinha (HET-CAM). O Perfil fitoquímico do extrato foi analisado quanto à presença de alcalóides, saponinas, antraquinonas, esteróides, taninos, flavonóides e compostos fenólicos, de acordo com métodos colorimétricos padronizados. Os resultados obtidos indicam que o extrato de Caryocar brasilense obtido por CO2 supercrítico demonstra atividade antimicrobiana frente às bactérias testadas, além de potencial antioxidante comparado ao padrão testado. Adicionalmente, o extrato de Caryocar brasilense obtido por CO2 supercrítico não apresenta efeitos tóxicos, mostrando-se um extrato seguro. Estes resultados fornecem perspectivas de desenvolvimento de produtos para o cuidado pessoal, principalmente aqueles com atividade antisséptica e os que minimizam os danos causados pelos radicais livres
Abstract: The cosmetic and pharmaceutical industries have an increasing interest in replacing synthetic antimicrobials in dermatological products due to increased microbial resistance to conventional antimicrobial agents. Caryocar brasiliense Camb (pequi) is a typical Brazilian Cerrado fruit tree. Its fruit is used as a vitamin source for culinary purposes and as a source of oil for the manufacture of cosmetics. Leishmanicidal and antimicrobial activities have been reported previously. This study was designed to evaluate the safety and efficacy of C. brasiliense extract obtained by supercritical CO2 extraction. The minimum inhibitory concentrations (MICs) against Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus were determined by the classical microdilution method. Antiseptic activity against these organisms was evaluated by the plate diffusion method. The antioxidant potential of the extract was evaluated using a method based on the oxidation of 2,2-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS). In vitro cytotoxicity and phototoxicity of C. brasiliense supercritical CO2 extracts were assessed using a tetrazolium-based colorimetric assay (XTT) and Neutral Red methods; eye irritation potential was assessed using the Hen's Egg Test ¿ Chorioallantoic Membrane (HET-CAM) Test Method. The extract¿s chemical profile was analyzed for the presence of alkaloids, saponins, anthraquinones, steroids, tannins, flavonoids, and phenolic compounds according to standard colorimetric methods. The C. brasiliense supercritical CO2 extract exhibits antimicrobial activity against all bacteria tested. It also possesses antioxidant activity, when compared to a vitamin E standard. We also found that the C. brasiliense (pequi) extract obtained by supercritical CO2 extraction did not present cytotoxic and phototoxic hazards This finding suggests that C. brasiliense supercritical may be useful for the development of cosmetic and/or pharmaceutical products, primarily for antiseptic skin products that inactivate, reduce, prevent, or arrest the growth of microorganisms with the inherent intent to mitigate or prevent disease as well as products that minimize damage caused by free radicals
