Research ArticleOpen accessIn the abstractIdentification and Characterization of Antibiotic-Producing Actinomycetes IsolatesMeera Kumari, Bat-Erdene Myagmarjav, Birendra Prasad, Madhusudan ChoudharyActinomycetes are a gram-positive, filamentous subgroup of bacteria most known for antibiotic production. In fact, most of the antibiotics available today have originated from actinomycetes, namely from the genus Streptomyces. Novel bacteria with antimicrobial activities have been discovered from bacterial screen studies for decades and there is still much more yet to be unearthed. One hundred seventy five strains of … …Current Research in Microbiology, Vol. 4, Issue 1 · 25 Jun 2013 · 15,437 accessesView PDFCite
Research ArticleOpen accessIn the abstractRapid Real Time PCR Based Detection of Cell Count in Case of Urinary Tract InfectionPoulomi Nandy, Ashoke Ranjan Thakur, Shaon Ray ChaudhuriMicrobial identification and antimicrobial susceptibility testing methods currently used in clinical microbiology laboratories require at least two to three days because they rely on the growth and isolation of micro-organisms. This long, but necessary, delay has enormous consequences on prophylactic usage of antimicrobial drugs. This study was an attempt to reduce this detection time span. Taq Man Real Time PCR … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 2 · 22 Jun 2013 · 8,214 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification and Mode of Action of Antibacterial Components from Melastoma malabathricum Linn LeavesMourouge Saadi Alwash, Nazlina Ibrahim, Wan Yaacob AhmadThe present study aimed to assess the antibacterial activity of the methanol extract of Melastoma Malabathricum Leaves (MMML), active fraction of M. Malabathricum Leaves (ML5) and isolated kaempferol-3-O-(2",6"-di-O-p-trans-coumaroyl)-β-glucopyranoside (Kf) and to describe the preliminary mode of action against Gram-positive and Gram-negative bacteria. The MMML extract was fractionated by Vacuum Liquid Chromatography (VLC) to afford M. malabathricum Leaves fractions (ML1-ML6) of … …American Journal of Infectious Diseases, Vol. 9, Issue 2 · 18 Jun 2013 · 12,621 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnti-Microbial, Anti-Oxidant and Anti-Ulcerogenic Effects of Shilajit on Gastric Ulcer in RatsMohamed-I. Kotb El-Sayed, Hatem-K. Amin, Ali-G. Al-KafProblem statement: To evaluate the effects and mechanisms of action involved in anti-ulcer, antioxidant and antimicrobial activities of different native shilajit samples. Approach: Shilajit samples were collected in the mountain region of Yemen (Al-Jouf and Rayma), Russia (Tien-Shan) and India (Kumoan). Stomach ulcers were induced in rats by oro-gastric ingestion of ethanol/HCl. Pre-treatment with ranitidine (100 mg kg-1, p.o.) and … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 1 · 10 Mar 2012 · 8,996 accessesView PDFCite
Research ArticleOpen accessIn the abstractStrains of Klebsiella Pneumoniae from Intensive Care Unit Producing CTX-M-15 Extended Spectrum Beta LactamasesI.R. Iroha, A.E. Oji, A.E. Nwakaeze et al.Problem statement: Resistance to third generation cephalosporins due to acquisition and expression of Extended Spectrum β-Lactamase (ESBL) among Gram-negative bacteria is on the increase. Infections involving extended spectrum beta lactamase bacteria are associated with significant morbidity and mortality. Therefore, infections due to ESBL isolates continue to pose a serious challenge to infection management worldwide. Since screening for ESBL is not … …Current Research in Microbiology, Vol. 2, Issue 2 · 6 Mar 2012 · 7,826 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtraction 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 abstractAntibacterial Activity of β-Cyclodextrin and 2-Hydroxypropyl-β-Cyclodextrin Trimethoprim ComplexesHsien-Kuo Sun, Madhumathi Seshadri, Scott Lingard et al.Problem statement: Cyclodextrin complexation has previously been shown to improve the solubility and dissolution properties of trimethoprim; however, no report provides an account of the effect cyclodextrin complexation has on the antibacterial activity of this agent. Approach: β-cyclodextrin and 2-hydroxypropyl β-cyclodextrin inclusion complexes of trimethoprim were prepared and confirmed by differential scanning calorimetry and proton nuclear magnetic resonance. The in-vitro … …Current Research in Microbiology, Vol. 2, Issue 1 · 26 Oct 2011 · 14,801 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Study of Antibacterial Susceptibility Patterns of the Bacteria Isolated from Patients' Blood Samples over Two PeriodsAziz Japoni, Mehdi Kalani, Abdolvahab Alborzi et al.Problem statement: Due to continuous changes in the frequencies and antibacterial susceptibility patterns of nosocomial pathogens, periodical surveillance of these fluctuations could help the clinicians to treat hospitalized patients more efficiently whenever empirical therapies need to be considered. This study was conducted to compare the prevalence of the bacteria recovered from bloodstream samples by Bactec 9240, over the two periods … …American Journal of Infectious Diseases, Vol. 7, Issue 1 · 27 Apr 2011 · 8,158 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Phytochemical Contents and Antimicrobial Activities of Malaysian Calophyllum RubiginosumSuhaib Ibrahim ALkhamaiseh, Muhammad Taher, Farediah AhmadProblem statement: Many species of plants in Malaysia are widely used in folk medicine. However, Calophyllum species have been used in traditional medicine for their therapeutic values for many years. Several studies reported that antimicrobial, antifungal, anti-HIV and anti-cancer compounds were isolated from numerous Calophyllum species. Approach: The stem bark was extracted by EtOH, after with it was fractionated with … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,573 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Antifungal Bacteriocin-Synthesizing Strains of Lactococcus lactis ssp. lactis as the Perspective Biopreservatives for Protection of Raw Smoked SausagesL.G. Stoyanova, E.A. Ustyugova, T.D. Sultimova et al.Problem statement: Screening for the effective bacteriocin-synthesizing strains of Lactococcus lactis as the perspective biopreservatives was performed.
