Research ArticleOpen accessIn the abstractInduction of a Soluble Anti-HIV-1 factor (s) with IFN-γ, IL-10, and β-Chemokine Modulating Activity by an Influenza-Bacterial Polyantigenic MixtureJosé W. Rodríguez, Nat O. Pagan, Mar C. Ocasio et al.Partial immune restoration may be obtained with highly active antiretroviral therapy (HAART), but specific anti-HIV-1 immune responses do not appear to improve substantially. We have demonstrated that a soluble factor(s) induced by a mixture of inactivated influenza and bacterial vaccines called polyantigenic immunomodulator (PAI), possesses strong immunoregulatory and anti- HIV-1 activities. In the present study, we show that culture fluids … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 6,845 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIsolation and Purification of Bacterial Strains from Treatment Plants for Effective and Efficient Bioconversion of Domestic Wastewater SludgeK. C.A. Jalal, Md. Z. Alam, Suleyman A. Muyibi, P. JamalForty six bacterial strains were isolated from nine different sources in four treatment plants namely Indah Water Konsortium (IWK) sewage treatment plant, International Islamic University Malaysia (IIUM) treatment plant-1,-2 and -3 to evaluate the bioconversion process in terms of efficient biodegradation and bioseparation. The bacterial strains isolated were found to be 52.2% (24 isolates) and 47.8% (22 isolates) in the … …American Journal of Environmental Sciences, Vol. 2, Issue 1 · 31 Mar 2006 · 7,575 accessesView PDF Cite

Review ArticleOpen accessIn the abstractRole of Cytokines and Transcription Factors in Periodontitis: A Review of Cellular and Molecular MechanismsAnne Carolina Eleutério Leite, Valéria Martins de Araújo Carneiro, Júlia Faria Nunes et al.Periodontal Diseases (PD) are characterized by pathological manifestation of host immune response to bacterial infection at the tooth/gingival interface. Evidences points periodontitis as a risk factor for pathological systemic conditions, such as, cardiovascular diseases and diabetes. The identification of host factors that determine their susceptibility to immune subversion can provide useful information in the pathogenesis of periodontitis. Protective acute inflammatory … …American Journal of Immunology, Vol. 11, Issue 4 · 9 Dec 2015 · 7,807 accessesView PDF Cite

Research ArticleOpen accessIn the abstractLIQUID AND VAPOUR PHASE ANTIBACTERIAL ACTIVITY OF EUCALYPTUS GLOBULUS ESSENTIAL OIL = SUSCEPTIBILITY OF SELECTED RESPIRATORY TRACT PATHOGENSBoukhatem Mohamed Nadjib, Ferhat Mohamed Amine, Kameli Abdelkrim et al.Essential Oils (EO) produced by medicinal plants have been traditionally used for respiratory tract infections and are used nowadays as ethical medicines for colds. Although several studies of Eucalyptus Globulus Labill. Essential Oil (EGEO) have been reported, there are no reports describing vapour activity of EGEO against bacterial respiratory tract pathogens. The aim of this study was to test the … …American Journal of Infectious Diseases, Vol. 10, Issue 3 · 3 Sep 2014 · 13,311 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordBiomolecular Identification of Bacteria Endophytic From Betel Leaf in Jambi City Forest Park Area as Antibiotic-Producing PotentialArzita, Miranti Sari Fitriani, Nyimas Myrna Elsa Fathia et al.Background and Objective: Muhammad Sabki City Forest Park in Jambi City has three types of betel plants that contain endophytic bacteria. In 2021, six isolates of endophytic bacteria with the potential for producing antibiotics (halo zone above 10 mm) have been isolated, which can kill Gram-negative (Escherichia coli) and Gram-positive (Staphylococcus aureus) test bacteria. that are 5 (five) isolates derived … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 15 Feb 2026 · 1,234 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordIsolation 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 PDF Cite

Research ArticleOpen accessAll words, across the recordIdentification of Major Cultivable Aerobic Bacteria in the Oral Cavity of Malaysian SubjectsKoshy Philip, Wuen Yew Teoh, Sekaran Muniandy, Hashim YaakobCulture dependent and culture independent methods have shown that about 600 species of bacteria inhabit the human oral cavity. While some oral microorganisms have a direct link to dental caries, periodontal disease and halitosis, opportunistic pathogens may be responsible for systemic diseases such as bacterial endocarditis, aspiration pneumonia, osteomyelitis in children, preterm low birth weight, coronary heart disease and cerebral … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 7,990 accessesView PDF Cite
