Research ArticleOpen accessIn the keywordsExtraction and Evaluation of Antibacterial Activity from Selected Flowering PlantsErlina Abdullah, Raha Ahmad Raus, Parveen JamalThe huge diversity of Malaysian flora has various chemical constituents that make them as outstanding natural product candidates for the treatment of infectious diseases. The screening practice for phytochemical compound in them is essential to explore more natural sources to replace synthetic antibiotics, which generally have side effects such as hypersensitivity, immune-suppression and allergic reactions. Antibacterial activities have been detected … …Current Research in Medicine, Vol. 3, Issue 1 · 20 Feb 2012 · 16,312 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of the Clinical Incidence and Correlation between Colorectal Cancer and MicroorganismsKalia Koutouvalis, Pablo Augusto BejaranoIn this single institution retrospective medical record review, patients diagnosed with colorectal cancer from the years 2018-2022 were evaluated to distinguish an associative linear relationship between diagnosed colorectal cancer and a positive result for the presence of an infectious microorganism. A total of 241 patients diagnosed with colorectal cancer accompanied by a test or order placed with the purpose of … …American Journal of Infectious Diseases, Vol. 20, Issue 1 · 27 Jun 2024 · 5,023 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation and Identification of Bacteria Leading to Microbial Spoilage of Sweet Potato and Screening for Antistaling Agents Running HeadDaoqi Liu, Huili Liu, Yuanyuan Dang et al.To develop natural preservatives tailored for sweet potatoes, the control effect of essential oils on the spoilage microorganisms of sweet potatoes is uncertain. Therefore, we first isolated and identified the dominant spoilage bacteria from spoiled sweet potatoes. Micrococcus aloeverae, Priestia aryabhattai, and Glutamicibacter arilaitensis were identified through screening, morphological observation, gram staining, and 16S rDNA assays. Subsequently, five plant essential … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 1 · 26 Apr 2024 · 5,221 accessesView PDFCite
Research ArticleOpen accessIn the abstractSelection of Probiotic Microorganisms Against Pathogens of Agricultural AnimalsSagidoldina Zhanar, Sadanov Amankeldi, Ratnikova Irina et al.The work was carried out on the selection of probiotic microorganisms to create an environmentally friendly therapeutic and preventive biological product that is active against pathogens of agricultural animals. According to the results of research, 3 strains of lactic acid bacteria were selected for the construction of a probiotic - Lactobacillus plantarum 1, Streptococcus salivarius 20 n, Lactobacillus fermentum 15 … …OnLine Journal of Biological Sciences, Vol. 21, Issue 4 · 27 Nov 2021 · 6,044 accessesView PDFCite
Research ArticleOpen accessIn the abstractConcentric Circles Painting Versus Back-and-Forth Scrubbing: A Comparison Between Two Skin Disinfection TechniquesKai Beng Tan, Yu Cheng Chiu, Audrey Tham et al.Traditionally, skin disinfection is performed in concentric circles. In recent years, there are studies which suggest that back-and-forth scrubbing could be a better technique. However, there is insufficient evidence to demonstrate which disinfection technique is better in reducing microbial load prior to invasive procedures. This study aims to compare the effectiveness of concentric circles painting and back-and-forth scrubbing skin disinfection … …International Journal of Research in Nursing, Vol. 12, Issue 1 · 24 Nov 2021 · 10,371 accessesView PDFCite
Review ArticleOpen accessIn the abstractRecognizing Dissolved Organic Matter with an Improved Fluorescence Regional Integral MethodZhang Jianguo, Wang Xinyi, Liu Xiaoman et al.The aim of this paper was to study transformations of Dissolved Organic Matter (DOM) in marl rock groundwater. To achieve this, we carried out a series of soil column experiments, using a DOM solution as the water sample and marl rock as the testing rock sample. Three-Dimensional Excitation-Emission Matrix Spectra (3DEEMS) were generated for DOM solutions and the Analytic Hierarchy … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 4 · 24 Dec 2019 · 7,288 accessesView PDFCite
Research ArticleOpen accessIn the abstractNovel Production of Two New Nonpolyenic Antifungal Macrolide Derivatives by Streptomyces Z26 Isolated from Moroccan Rhizospheric SoilAhmed Nafis, Brahim Oubaha, Najoua Elhidar et al.The aim of our study was to screen Moroccan actinomycete isolates able to produce nonpolyenic antifungal metabolites in order to contribute to limiting the problem of fungal infections emergence in particular mycotic diseases and to discover known antifungal families, especially nonpolyenic drugs. 480 isolates were tested against 5clinically pathogenic Candida species. Several methods have been used to study the polyenic … …OnLine Journal of Biological Sciences, Vol. 18, Issue 2 · 8 Mar 2018 · 8,459 accessesView PDFCite
Research ArticleOpen accessIn the abstractBacteria Contaminants and their Antibiotic Sensitivity from Selected Herbal Medicinal Products from Eldoret and Mombasa, KenyaLucia Keter, Richard Too, Nicholas Mwikwabe et al.Herbal products are used worldwide for the treatment and prevention of various diseases and currently represent a substantial proportion of the global drug market. However, these products have the potential of being contaminated by different microorganisms due to poor hygienic practices during handling, processing and packaging. The main aim of this study was to evaluate microbial quality of herbal products … …Current Research in Microbiology, Vol. 7, Issue 1 · 28 Jan 2016 · 17,160 accessesView PDFCite
Research ArticleOpen accessIn the abstractHemodynamic Catheters: The Reprocessing, Cleanliness and in vitro Biofilm Formation by Enterococcus faecium in a Continuous Flow ModelCleber Galdino da Silva, Edson Pires de Oliveira, Ednalva Miranda Guizi et al.Reprocessing single-use devices to cut costs is a common practice in hospitals around the world. In Brazil, there are few studies of reprocessing hemodynamic catheters and thus, this study aimed to evaluate the effectiveness of reprocessing hemodynamic catheters before and after biofilm formation in vitro using a continuous flow model. We used a sterility test and Scanning Electron Microscopy (SEM) … …American Journal of Infectious Diseases, Vol. 11, Issue 2 · 24 Jul 2015 · 7,808 accessesView PDFCite
