L’activité antimicrobienne des huiles essentielles de galles de Pistacia atlantica récoltées dans trois régions (Aïn-Oussara, Laghouat et Kheneg) a été évaluée sur sept souches pathogènes (Escherichia coli, Bacillus cereus, Pseudomonas aeruginosa, Staphylococcus aureus, MRSA+, Salmonella typhi et Candida albicans), en utilisant les méthodes de diffusion sur gélose, de microdilution et celle de microatmosphère (seulement pour Candida albicans). Les huiles essentielles ont révélé un effet antimicrobien remarquable contre les micro-organismes testés, avec des valeurs de CMI et de CMB variant de 0,13 à 7,99 μl/ml et de 0,25 à 7,99 μl/ml, respectivement. Une activité importante a été observée pour les échantillons de la station Kheneg contre l’espèce Candida albicans avec une zone d’inhibition de 68 mm (50 μl). Ces résultats suggèrent que les huiles essentielles testées pour leur activité antimicrobienne peuvent être classées comme bactéricides.

A resistência microbiana tem se mostrado um problema de proporções mundiais, causando estado de morbidade e mortalidade em diversos pacientes. Em vista disso, tem crescido a busca por métodos alternativos naturais de profilaxia. A investigação clínica sugere que o Extrato de Cranberry está entre as melhores propostas de prevenção natural. O Cranberry (Vaccinium macrocarpon) é um fruto que tem crescido comercialmente pelo sabor e propriedades benéficas à saúde. Dentre as formas comercializadas estão: o suco, o chá e as cápsulas contendo o extrato seco. A ação desta planta está relacionada ao tratamento de doenças do trato urinário, por possuir substâncias que inibem a adesão bacteriana ao epitélio do trato urinário, dificultando sua proliferação e reprodução. Dentre todas as infecções relacionadas à assistência a saúde, a Infecção do Trato Urinário é a mais frequentemente associada a procedimentos invasivos. Se não for tratada, pode resultar em complicações como pielonefrite aguda, bacteremia e pionefrose. Portanto, cranberry pode ser uma nova alternativa para o combate das infecções uroepiteliais, por ser um produto natural de preço acessível, e com formas de comercialização diversificada, ao contrário dos antimicrobianos convencionais, que por sua vez são caros e podem acabar causando resistência nos micro-organismos. Este trabalho teve como objetivo avaliar in vitro a atividade antimicrobiana do extrato de Cranberry, adquirido em farmácia de manipulação, sobre 8 micro-organismos isolados de infecções urinárias. As cepas utilizadas, adquiridas da coleção da FIOCRUZ, foram: Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Proteus mirabilis, Serratia marscecens, Staphylococcus aureus, Enterococcus faecalis e Enterococcus faecium. No estudo, foram utilizados o caldo Mueller Hinton (MH), Extrato de Cranberry e as bactérias patogênicas. O ensaio foi realizado em triplicata, com o uso de um controle de crescimento dos micro-organismos e o experimento para avaliação do crescimento bacteriano na presença do extrato. A turbidez foi medida com o auxílio de um espectrofotômetro, no comprimento de onda de 600 nm, antes e após 24 horas de incubação à 37 ºC. O procedimento forneceu a Densidade Ótica, do qual possibilitou a identificação da inibição microbiana. Para análise estatística foi utilizado o Teste t de Student. O Extrato de Cranberry apresentou atividade antimicrobiana sobre as bactérias Staphylococcus aureus, Klebsiella pneumoniae, Escherichia coli, Serratia marscecens e Enterococcus faecalis (p < 0,05), confirmando seu efeito benéfico em infecções urinárias. No entanto, não teve efeito inibitório significativo sobre Pseudomonas aeruginosa, Proteus mirabilis e Enterococcus faecium (p > 0,05).

Abstract With the increase of general knowledge and the advancement of science and technology, antibacterial substances were used more than antibiotics. In our current study, the antibacterial virtues of CFO/BiOI nanocomposite were investigated due to its high importance on Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Bacillus cereus. MIC, MBC , Disk Diffusion and IC50 tests Cefalotin (CF), Amoxicillin (AMX), Gentamicin (GM), Trimethoprim-sulphamethoxazole (SXT) and Ceftriaxone (CRO) antibiotics in concentration 30W, 10i, 10t , 25h and 30 were used to find the antibacterial properties of the synthesized nanocomposite, respectively. For the synthesis of nanocomposites polyethylene glycol (PEG) and sulfonic acid was used as a solvent. It is noteworthy that the synthesis was performed by heat dissolution method without the presence of surfactant. Also, various techniques such as X-Ray Diffraction(XRD), Scanning Electron Microscope (SEM), High resolution mapping and Energy Dispersive X-ray spectroscopy (EDAX) have been used to determine the properties of produced nanocomposites. SEM test results showed that the formed nanoparticles were globular and their size was limited area of 22 to 34 nm. The results showed CFO / BiOI nanocomposite exhibits strong significant biological activity against Bacillus cereus. The results of MBC (Minimum Bactericidal Concentration) and MIC (Minimum Inhibition Concentration) tests for CFO/BiOI nanocomposites on bacteria were examined in the range of 0.12-0.48 mg/ml and 0.06 to 0.24 mg/ml respectively. According to the results, the minimum IC50 value was determined at a concentration of 0.061 mg/ml. On the other hand, the most resisting and susceptible bacteria in this method were Pseudomonas aeruginosa and Bacillus cereus, respectively. These findings are identical to those of a prior study on CoFe2O4 nanoparticles antibacterial properties. MBC of the nanocomposites, 50 µl from all the tubes that showed no obvious bacterial growth were distributed on BHI agar plates and incubated for 24 h at 37 ◦C. The MBC endpoint is defined as the lowest concentration which killed 98% of the bacterial population.

Aim: This work was carried out in order to reduce the isopropanol contain of a World Health Organization (WHO) basic alcohol based hand rub (ABHR) formulation by substituting part of it with ethanol and essential oils. Study Design: A quasi-experimental design was used, based on WHO basic formulation modification, antimicrobial assessment followed by a panel test and challenge test of the best formulation. Place and Duration of the Study: The study was carried out in different laboratory of the University of Yaoundé 1 during March 2017 to July 2018. Methodology: This study was performed by producing different formulations nested from the WHO basic formulation and testing their antimicrobial capacity on selected strains based on the microbial percentage reduction. Following this, the best formulation was compared to two commercial products trough a panel test and later challenged with selected organism (Staphylococcus aureus SR196, Salmonella Typhi 15SA, Escherichia coli ATTC25922 and Pseudomonas aeruginosa PA01) inoculated in the product after different storage periods for one year and the antimicrobial stability assessed on the same strain for the same length of conservation. Results: The partial substitution of isopropanol with ethanol and Piper nigrum and Syzygium aromaticum essential oils proved to possess more antimicrobial properties than the original WHO formulation. The best formulation caused a 6 Log cells/ml reduction of the initial population compared to the 4 Log cells/ml of the WHO formulation. The product also proved to maintain its activity for one year and to be able to deactivate possible contaminations by Salmonella Typhi 15SA, Staphylococcus aureus NCTC10652, Escherichia coli ATCC25922, Pseudomonas aeruginosa PA01. Conclusion: The present work is a contribution to the improvement of ABHRs and could permit the reduction of hand hygiene associated infections in industries and health care facilities.
