Full textThis project evaluates the scalability and viability of a disinfectant tablet capable of being diluted in water and purifying any physical space. Its purpose is to trade it in the Peruvian market, satisfying the needs of our clients, as well as solving the two problems encountered. On the one hand, the high pollution due to plastic packaging puts the entire world population at risk and as a consequence, less harmful alternatives are being sought in the market. On the other hand, the impact of COVID-19 has caused more consumers to seek products with a high level of disinfection. For all this, it was figure out way to find a disinfectant product that does not pollute the environment thanks to tablets with an aluminum container and providing disinfection safety for the target audience The research of this work was focused on the development of the disinfectant tablet trade in Metropolitan Lima and Callao for socioeconomic sectors B and C, since there is currently no company in the national market that offers a product similar to ours. In this way, the objective of the project is to publicize the innovative potential and transmit its added value to consumers. After the financial evaluation, it was determined that the initial investment required by the shareholders would be 11,350 soles for each one, giving a total of 56,750 soles. While at the end of the operations of the 3 year of the project, a net present value of 14,573 soles would be obtained, an internal rate of return of 33% and that the total investment would be recovered in 2.46 years.

Full textO presente trabalho, teve como principal objectivo avaliar a eficácia de diferentes desinfectantes na indústria Agro – Alimentar. Para este efeito, testaram-se diferentes desinfectantes, produzidos pela Mistolin e por uma marca concorrente. Foram recolhidas amostras de superfícies, com ajuda de zaragatoas, em diferentes sectores da indústria Agro – Alimentar, sector das carnes, sector dos vinhos e sector dos lacticínios. Todas as amostras foram recolhidas em diferentes condições de higienização e posteriormente semeadas em meio PCA, para quantificação dos efectivos microbianos, sendo os resultados expressos em UFC por cm2. Ainda neste trabalho, foram efectuadas análises microbiológicas às águas utilizadas no processo de higienização, adicionando um redutor, tiossulfato de sódio, para inibir o efeito do cloro sobre os microrganismos presentes na água. Analisou-se ainda a presença ou ausência de resíduo químico de desinfectante, com tiras indicadoras de pH e com um indicador para produtos alcalinos, a fenolftaleína. Com a primeira formulação do desinfectante da Mistolin, a percentagem de eficácia varia entre 47 e 71%, enquanto no caso da concorrência varia entre 85 e 93%, para a mesa de vísceras vertical e horizontal, respectivamente. Após o desenvolvimento da nova formulação da Mistolin, as percentagens sofreram um aumento significativo, variando entre 94 e 95%. No caso da queijaria, as percentagens variam entre 93-97% e no caso da concorrência variam entre 92-95%, para os diferentes pontos de recolha. Em todos os pontos da adega, a eficácia é ligeiramente superior no caso da Mistolin. As análises microbiológicas efectuadas nas amostras de água, apresentam valores de microrganismos abaixo do permitido por lei. Com as tiras de pH e com a fenolftaleína, foi possível verificar a ausência de qualquer resíduo químico da solução desinfectante. No futuro, seria interessante desenvolver mais estudos, nomeadamente verificar a acção bactericida contra microrganismos específicos de cada sector.
This project’s main objective is to assess the efficiency of different disinfectants in the agro-food industry. For this purpose, different disinfectants, produced by Mistolin and by a competing brand, were tested. Samples were collected, using swabs, from different agro-food industry surfaces in the meat, wine and dairy sectors. All samples were collected under different hygiene conditions and subsequently plated on PCA medium for microbial quantification; the results are expressed in CFU per cm2. This project also involved the microbiological analysis of the water used in the cleaning process, by using a reducing agent, sodium thiosulfate, with the aim of cut the chlorine’s effect over the microorganisms in the water. An alkaline sensible chemical, phenolphthalein, and pH indicating strips were used to determine the presence or absence of any disinfectant’s chemical residue. With the Mistolin’s disinfectant first formulation the efficiency varies between 47% and 71%, whereas the efficiency of the competing brand’s product is ranged between 85% and 93% for the viscera vertical and horizontal table, respectively. However, after the development of a new Mistolin’s disinfectant formulation the efficiency percentage was significantly increased, now being comprised between 94% and 95%. Regarding the dairy sector, Mistolin’s efficiency is set from 93% to 97%, while the competing brand’s product varies from 92% to 95%. About the wine sector, the Mistolin’s efficiency is slightly higher in all the collecting locations. The microbiological analysis carried out in the water samples revealed microorganisms values bellow the ones set by law. The use of pH indicating strips and phenolphthalein allowed verifying the absence of any chemical residue from the disinfectant solution. In future studies, it would be interesting to evaluate the bactericidal action against microorganisms specific to each sector.

Full textIntrodução e objectivos: O tratamento endodôntico consiste na preparação químico-mecânica, nomeadamente a instrumentação do sistema tridimensional de canais, irrigação e medicação intracanalar, que visam à desinfecção do sistema de canais radiculares. Posteriormente o sistema de canais radiculares é obturado, ou seja, selado, impedindo a re-infecção do dente. O seu sucesso é significativamente influenciado pela presença de bactérias nos canais radiculares no momento da obturação. (Fabricius et alii. 2006, Siqueira e Rôças 2008, Stuart et alii. 2006, Waltimo et alii. 2005) Não obstante o facto de a infecção endodôntica ser polimicrobiana, neste trabalho será dado ênfase ao Enterococcus faecalis, que é uma bactéria com elevada patogenicidade e com elevada prevalência na patologia Endodôntica. (Kayaoglu e Ørstavik 2004, Sedgley et alii. 20062, Siqueira e Rôças 2008, Stuart et alii. 2006, Ozbek et alii. 2009) Convencionalmente, a irrigação é realizada com NaOCl ou CHX e a medicação intracanalar, se o tratamento for multi-sessões, é feita habitualmente com Ca(OH)2. O objectivo deste trabalho é verificar as limitações dos princípios activos supracitados ao E.faecalis. Materiais e métodos: Foi realizada uma pesquisa bibliográfica nas bases de dados PubMed e Embase usando as seguintes palavras-chave: “endodontic infection”, “endodontic microbiology”, “endodontic disinfection”, Enterococcus faecalis”, “virulence”, “culture”, “topic disinfection in endodontics”, “endodontic treatment”, “root canal disinfection”, “irrigating solutions”, “Enterorococcus faecalis erradication in endodontics” publicados entre 2003 e 2011, da qual resultaram 73 artigos que continham informação relevante para este estudo e cumpriam os critérios estabelecidos. Resultados: Verificou-se que tanto a CHX, como o NaOCl e o Ca(OH)2 possuem limitações na erradicação do Enterococcus faecalis, sendo que não há consenso quanto ao protocolo de desinfecção ideal. RESUMO vi Conclusões: Um método eficaz proposto para a erradicação do E.faecalis consiste em boa técnica asséptica, aumento do calibre apical até #30, irrigação alternada com NaOCl a 2,5%, uma solução quelante como EDTA a 17% e CHX a 2%, e como medicação intracanalar, se tratamento for multi-sessão, com CHX em gel a 2%. Introduction and objectives: Root canal therapy consists in chemo-mechanical preparation, particularly with the instrumentation of the three-dimensional system of canals, irrigation and dressing, aimed at disinfecting the root canal system which is then sealed, preventing the re-infection of the tooth. Its success is significantly influenced by the presence of bacteria in root canals at the time of filling. (Fabricius et alii. 2006, Siqueira e Rôças 2008, Stuart et alii. 2006, Waltimo et alii. 2005) Even though the endodontic infection is polymicrobial, this work will be given emphasis to Enterococcus faecalis, a bacterium that is highly pathogenic and high prevalent in Endodontic pathology. (Kayaoglu e Ørstavik 2004, Sedgley et alii. 20062, Siqueira e Rôças 2008, Stuart et alii. 2006, Ozbek et alii. 2009) Conventionally, irrigation canal is performed with NaOCl or CHX and intracanal medication if treatment is multi-session, is usually made with Ca(OH)2.The aim of this study is to observe the limitations of the above active substances against E.faecalis. Materials and methods: It was performed a literature search in the databases PubMed and Embase with the following keywords: “endodontic infection”, “endodontic microbiology”, “endodontic disinfection”, Enterococcus faecalis”, “virulence”, “culture”, “topic disinfection in endodontics”, “endodontic treatment”, “root canal disinfection”, “irrigating solutions”, “Enterorococcus faecalis erradication in endodontics” published between 2003 and 2011, of which resulted in 73 articles that contained information relevant to this study and met the established criteria. Results: It was found that both CHX, such as NaOCl and Ca(OH)2 have limitations in eradicating Enterococcus faecalis, and there is no consensus on the ideal protocol disinfection. Conclusions: An effective method proposed for the eradication of E.faecalis consists of good aseptic technique, increasing the apical size # 30, alternating irrigation ABSTRACT viii with 2.5% NaOCl, 17% EDTA as a chelating solution and 2% CHX and as intracanal medication, if treatment is multi-session, with 2% gel CHX.

Full textLos datos epidemiológicos que poseemos en nuestro país señalan que la mayor parte de los brotes de toxiinfecciones alimentaria se desencadenan en el ámbito doméstico. Debido a ello, cada vez más se están desarrollando formulaciones químicas con actividad desinfectante para ser utilizadas en el hogar. La mayoría de los productos desarrollados tienen como objetivo el actuar como bactericidas. Sin embargo, poco se estudia respecto a su posible actividad fungicida. Encontrado microorganismos patógenos, como Candida albicans y otros alterantes. Por este motivo, nuestro trabajo pretende comparar la actividad fungicida de los desinfectantes utilizados en el ámbito doméstico, para conocer su eficacia real y su aplicabilidad.
Pretendemos evaluar el empleo de las técnicas impedanciométricas, ya que se trata de una metodología particularmente adecuada a pruebas de desinfectantes en superficies. El protocolo deja la adherencia en el mismo estado morfológico y no los enfrenta a un estrés por remoción y por lo tanto no influye en la eficacia del desinfectante(Gibson y col., 1995).
OBJETIVOS:
Evaluar la eficacia funguicida de los productos comerciales de uso domestico, aplicando las normas internacionales de evaluación UNE EN-1275 y 1650.
Desarrollar una técnica rápida de evaluación de estos mismos productos comerciales.
Desarrollar sistemas que simulen situaciones reales de uso.
Verificar su eficacia, una vez adaptada la metodología, ensayar y comparar la eficacia de los diferentes desinfectantes en condiciones reales de uso.
MATERIAL Y MÉTODO:
La fase experimental del proyecto se realizó en 5 etapas:
Aplicación de las normas Españolas UNE-EN 1275 y 1650 para la evaluación de la actividad fungicida en 20 productos comerciales.
Diseñar un método rápido de screening a dos concentraciones y dos tiempos de contacto, para ayudar a discriminar los compuestos y poder encontrar su rango de acción.
Adaptar las normas a una técnica impedanciométrica, para automatizarla y permitir una detección de la actividad desinfectante en un menor tiempo.
Analizar los efectos de las condiciones ambientales en la viabilidad de las cepas fúngicas en varias superficies.
Emplear la técnica de epifluorescencia directa, con tinción vital de fluorescencia y captura de imagen.
Se evaluó la actividad fungicida en tela de algodón
RESULTADOS:
Nuestros resultados señalan que el producto con hipoclorito sódico presenta mayor actividad fungicida, tanto para las levaduras como para esporas de mohos, así como el glutaraldehído, que también supero las 2 normas UNE EN-1275 y 1650.
Al mismo tiempo, hemos constatado la aplicabilidad de la impedancia como sistema para evaluar el recuento de estos microorganismos y poder evaluar la eficacia fungicida de diversas sustancias en un menor tiempo y en con una mayor eficacia.
CONCLUSIONES:
Es posible la adaptación de la metodología estándar a otra rápida, con una reducción en el tiempo de incubación y una simplificación de las pruebas a realizar.
La adaptación del protocolo normalizado a un método de screening se realizo seleccionando dos concentraciones de los productos a emplear (80% y 20%) a dos tiempos de contacto (15 y 60 minutos). Los resultados obtenidos permiten clasificar los productos por diferentes niveles de eficacia.
El producto con más amplio espectro fungicida es el hipoclorito sódico (lejía), tanto para levaduras como para esporas de mohos. Con este producto se consigue una reducción de más de 5 unidades logarítmicas de recuento con la menor concentración en menos de 5 minutos de contacto con gran diferencia respecto al resto.
Los productos estudiados poseen una actividad desigual, dependiendo de las condiciones del ensayo (concentración, el tiempo de exposición y el microorganismo utilizado).
INTRODUCTION
The epidemiological data that we have in our country show that most food poisoning outbreaks happen in home environment. For this reason, formulations of detergents with disinfectant activity are being developed. Most of the new products act as bactericides. However, there is not much information about their possible fungicide activity except from some pathogen microoganisms like Candida. The main aim of this study was to compare fungicide activity of disinfectants most commonly used at home in order to know their real efficiency and applicability. Impedanciometric techniques were used as an appropriated methodology to test disinfectant in surfaces. The protocol left the adherence in the same morphologic state and did not confront them to stress by removal and therefore did not have influence in the disinfectant efficiency (Gibson et al., 1995).
OBJECTIVES.
To evaluate the fungicide efficiency of domestic-use commercial products, applying the international norm of evaluation (UNE EN-1275 and 1650).
To develop a fast evaluation technique of the same commercial products.
To develop systems that simulate real situations.
To verify their efficiency, once the methodology is adapted, test and compare the efficiency of the different disinfectants in real use conditions.
RESULTS.
Our results showed that the product with sodium hypoclorite and glutaraldehide both had the higher fungicide activity for yeast and mold spores. At the same time, we constated the applicability of the impedance as a system to count these microorganisms and evaluated the fungicide efficiency of several substances in less time and with more efficiency.
CONCLUSIONS.
It was possible to adapt the standard methodology to a faster one, with a reduction in time of incubation and a simplification of the tests.
The adaptation of the standardised protocol to a screening method was done selecting two concentrations of the products (80% and 20%) and two contact times (15 and 60 minutes). The results obtained allowed the classification of the products by efficiency levels.
The product with higher fungicide activity was the sodium hypochlorite (bleach), both for yeast and mold spores. With this product was obtained a reduction of more than 5 logarithmic units with the smaller concentration in less than 5 minutes of contact and with a high difference with the others.
The studied products had different activity, depending on the test conditions (concentration, exposure time and microorganisms used).

Full textEl desarrollo de estudios sobre la actividad antimicrobina, que permitan la selección de productos biocidas eficaces puede suponer una importante mejora en la lucha contra las IN.
Se estudió in vitro la actividad antimicrobiana del ácido peracético al 0.26% (Perasafe®) en comparación con el glutaraldehído alcalino al 2% (Cidex®), frente a Mycobacterium avium- Mycobacterium intracelulare (MAI), Mycobacterium tuberculosis H37Rv, Mycobacterium fortuitum y Mycobacterium chelonae. Perasafe® fue micobactericida y tuberculocida (factor de reducción ? 5 log10) en 20 min. de contacto; mientras que Cidex® lo fue en 30 min. de exposición. MAI fue la micobacteria más resistente.
También demostramos la eficacia de Perasafe® en comparación con Cidex® para la desinfección de broncoscopios contaminados experimentalmente con M.tuberculosis H37Rv y MAI. Ambos productos consiguieron un factor de reducción ?5 tras 10 min. de contacto frente a M.tuberculosis, y tras 20 min. frente a MAI. Así pues, como demuestran los estudios in vitro y de "uso simulado", Perasafe®, es un desinfectante de alto nivel efectivo frente a micobacterias y constituye una posible alternativa al glutaraldehído alcalino al 2% en la desinfección de broncoscopios.
Se evaluó la actividad antimicrobiana frente a M.tuberculosis H37Rv, MAI, M.kansasii y M.chelonae de Korsolex® AF. La concentración del 1% fue eficaz frente a todas las micobacterias ensayadas en 60 min. de contacto. Estos datos sugieren que los productos biocidas que contienen aminas podrían ser útiles en la desinfección intermedia y de alto nivel de los dispositivos médicos.
Acinetobacter baumannii destaca por su habilidad para desarrollar y transmitir resistencias antimicrobianas y por ser un patógeno nosocomial emergente difícil de erradicar. Se estudiaron 9 cepas multirresistentes, con adquisición progresiva de la resistencia a los antibióticos betalactámicos aisladas en el transcurso de un brote epidémico. Para ello, se realizó un estudio de suspensión cuantitativo según el European Standard EN 1040. Todas las cepas de A.baumannii fueron sensibles a todos los antisépticos (Sterillium®, 2 formulaciones alcohólicas no comercializadas, Hibiscrub® y Clorina®) y desinfectantes evaluados (Virkon® e Instrunet superficies®). Se comprobó que la resistencia a múltiples antibióticos betalactámicos en cepas de A.baumannii no se asocia a resistencia o descenso de sensibilidad a los biocidas.
Por otro lado, hemos analizado el espectro de actividad antimicrobiana de Virkon siguiendo las normativas AFNOR. Los resultados obtenidos demuestran que Virkon® al 1% es un desinfectante de bajo nivel por ser un biocida con efecto antimicrobiano rápido (5 min.) frente a bacterias vegetativas (gramnegativas y grampositivas), levaduras, virus y micobacterias no tuberculosas en ensayos cuantitativos de suspensión, pero únicamente bactericida en los ensayos con portagérmenes.
Finalmente, se evaluó la eficacia de un compuesto clorado (Solprogel®) frente al VIH-1 y VHB. La actividad virucida del VIH-1 se estableció mediante un ensayo de infectividad en células MT-2 y la del VHB midiendo la inhibición de la actividad de la DNA polimerasa (DNA-P). En ambos casos, la actividad antimicrobiana de Solprogel® se comparó con la del dicloroisocianurato sódico (NaDCC). Solprogel® y NaDCC, a una concentración de 120 ppm y 100 ppm de cloro disponible, respectivamente, inhiben el VIH-1 en 5 min. de contacto. La DNA-P del VHB fue sensible a la inhibición por los dos desinfectantes, requiriendo 960 y 1.000 ppm de cloro disponible para Solprogel® (16%) y NaDCC, respectivamente y un tiempo de exposición mínimo de 2 min.
Nosocomial infections (NI) lead to a high morbidity and mortality, significant staff work-loads and a high economic cost. The effective use of biocides, antiseptics and disinfectants along with the disinfection of surfaces and medical devices, hand washing and barrier techniques make up the means of prevention of NI.
The development of studies in antimicrobial activity, which allow for the selection of effective biocidal products, could lead to an important improvement in the fight against IN.
In vitro studies were made of the antimicrobial activity of peracetic acid at 0.26% (Perasafe®) in comparison to the 2% alkaline glutaraldehyde (Cidex®) against Mycobacterium avium- Mycobacterium intracelulare (MAI), Mycobacterium tuberculosis H37Rv, Mycobacterium fortuitum and Mycobacterium chelonae. Perasafe® was mycobactericidal and tuberculocidal (reduction factor ? 5 log10) after 20 minutes of contact. For Cidex®, 30 minutes of exposure was required. MAI was the most resistant mycobacterium.
We also demonstrated the effectiveness of Perasafe® compared to Cidex® for the disinfection of bronchoscopes experimentally contaminated with M. tuberculosis H37Rv and MAI. Both products achieved a reduction factor ? 5 after 10 minutes contact with M. tuberculosis and after 20 minutes with MAI. So, as demonstrated in in vitro studies and in simulated use, Perasafe® is a disinfectant with a high level of effectiveness against mycobacteria and would be a possible alternative to 2% alkaline gluteraldehyde for the disinfection of bronchoscopes.
The antimicrobial activity of Korsolex® AF against M.tuberculosis H37Rv, MAI, M.kansasii and M. chelona was evaluated. After 60 minutes contact the 1% concentration was effective against all the mycobacteria studied. These data suggest that biocidal products that contain amines could be useful in the intermediate and high level disinfection of medical devices.
Acinetobacter baumannii is noted for its ability to develop and transmit antimicrobial resistances and has become an emerging pathogenic nosocomial infection that is difficult to eradicate. Nine multi-resistant strains were studied. These had progressive acquisition of resistance to betalactamate antibiotics and were isolated during an epidemic outbreak. In this case, a quantitative suspension study according to European Standard EN 1040 was performed. All the strains of A. baumannii showed sensitivity to all the studied antiseptics (Sterillium®, two non-commercialised alcoholic formulations, Hibiscrub® and Clorina®) and disinfectants (Virkon® and Instrunet superficies®). This proved that resistance to multiple betalactamate antibiotics in strains of A. baumannii is not associated with resistance or decrease in sensitivity to biocidals.
On the other hand, we also analysed the antimicrobial activity spectrum of Virkon® according to the AFNOR regulations. The results obtained demonstrate that Virkon® at 1% concentration is a poor disinfectant to be a rapid antimicrobial effect biocide (5 minutes) against vegetative bacteria (gram negatives and gram positives), yeasts, viruses and non-tuberculoid mycobacteria in quantitative suspension studies. It was only bactericidal in the studies using the germ-carrier method.
Finally, the efficacy of a chloride compound (Solprogel®) against VIH-1 and VHB was evaluated. The virucidal activity against the VIH-1 was established by means of an infectivity study in MT-2 cells and for that of the VHB by measuring the inhibition of the DNA polymerase (DNA-P) activity. In both cases, the antimicrobial activity of Solprogel® was compared to that of sodium dichloroisocyanurate (SDIC). Solprogel® and SDIC at respective concentrations of 120 ppm and 100 ppm of available chlorine inhibited VIH-1 after 5 minutes of contact. The DNA-P of the VHB was sensitive to inhibition by both disinfectants, requiring 960 and 1,000 ppm of available chlorine for 16% Solprogel® and SDIC respectively, and a minimum exposure time of 2 minutes.

Full textLas puntas o conos de gutapercha son normalmente el material de obturación de elección en los tratamientos de endodoncia. Estas son ampliamente utilizadas por el odontólogo ya que presentan diversas ventajas. Se comercializan en cajas selladas y estériles, condición que se pierde al abrir el dispensador que las contiene cada vez que se realiza una obturación. Surge entonces la necesidad de desinfectar las puntas mediante su inmersión en una solución desinfectante que no altere la estructura del material y sus propiedades antes de introducirlos al conducto y asegurar que se encuentran libres de una carga bacteriana que lleve al fracaso del tratamiento. El propósito de este estudio fue evaluar las soluciones desinfectantes de gluconato de clorhexidina al 2%, hipoclorito de sodio al 5,25% y alcohol de 70° a los tiempos de 1 y 3 minutos de inmersión, en la desinfección de los conos de gutapercha previamente contaminados con cepas ATCC de Staphylococcus Aureus, Actinomyces, Enterococcus faecalis, y Candida albicans. El gluconato de clorhexidina al 2% y hipoclorito de sodio al 5,25% no mostraron evidencia estadísticamente significativa que demuestre ser mejor al alcohol de 70° en la descontaminación de los conos de gutapercha. Se concluyó que las soluciones de gluconato de clorhexidina al 2%, de hipoclorito de sodio al 5,25% y alcohol de 70° son eficientes en la desinfección de los conos de gutapercha.
