1. Characterization of Lactobacillus plantarum strains isolated from Turkish pastırma and possibility to use of food industry
Abstract Five Lactobacillus plantarum strains (which were previously isolated from Turkish pastırma), were evaluated for the possibilities of using in the food industry. Antimicrobial properties, metabolic activities, exopolysaccharide production and antibiotic resistance were investigated. It was also assessed probiotics features such as adhesion ability,

2. Methodology Development and Validation of Amphotericin B Stability by HPLC-DAD
The high worldwide consumption of antibiotics and their complex impurity profiles has drawn the attention of the scientific community to the development and validation of stability methods for these drugs. Amphotericin B is an antibiotic that is a natural fermentation product of bacterium Streptomyces nodosus, used as a broad-spectrum antifungal agent, and i

3. Mitomycin C in the Endoscopic Treatment of Laryngotracheal Stenosis: Systematic Review and Proportional Meta-Analysis
Abstract Introduction Mitomycin C is a natural antibiotic that has been used to inhibit the proliferation of fibroblasts in scar tissue. Objective To evaluate the effectiveness and safety of topical Mitomycin C as an adjuvant in the endoscopic treatment of laryngotracheal stenoses. Data synthesis A systematic review of experimental or observational st

5. Structure and Absolute Configuration of Secondary Metabolites from Two Strains of Streptomyces chartreusis Associated with Attine Ants
The antibiotic streptazolin (1), its E-isomer (2), along with the stereoisomers strepchazolin A (3) and strepchazolin B (4) and the inorganic compound cyclooctasulfur (5) were produced in solid culture by Streptomyces chartreusis ICBG377, which was isolated from the fungal garden of the leaf-cutter ant Acromyrmex subterraneus brunneus. This is the first time

6. Inibição do crescimento de microrganismos patogênicos induzida por butenolídeos análogos aos cadiolídeos
The increasing number of antibiotic resistant microorganisms requires the development of new drugs. In this context, natural cadiolides are promising leads as they present potent antimicrobial activity and low cytotoxicity. In this work we report the synthesis of 21 new cadiolide analogues. The synthesis involved a Diels−Alder cycloaddition/ cycloreversion

7. Biotic Contamination and Possible Ways of Sterilization: A Review with Reference to Bamboo Micropropagation.
ABSTRACT Multipurpose use of bamboo in rural life makes it as poor man’s timber in Asian countries. Deforestation and industrialization leads to destruction of natural forest. To replenish, a rapid plantation of bamboo could be one of the possible solutions. Bamboo is propagated mainly by vegetative methods though it is not suitable for large scale plantat

8. Ocellatin peptides from the skin secretion of the South American frog Leptodactylus labyrinthicus (Leptodactylidae): characterization, antimicrobial activities and membrane interactions
Abstract Background The availability of antimicrobial peptides from several different natural sources has opened an avenue for the discovery of new biologically active molecules. To the best of our knowledge, only two peptides isolated from the frog Leptodactylus labyrinthicus, namely pentadactylin and ocellatin-F1, have shown antimicrobial activities. The

9. Assessment of a natural, non-antibiotic blend on performance, blood biochemistry, intestinal microflora, and morphology of broilers challenged with Escherichia coli
ABSTRACT The effect of a non-antibiotic growth-promoting component composed of natural phytomolecules, direct-fed microbials, glucomannan oligosaccharides, and organic acids on the performance, intestinal morphology and microbiology, plasma biochemistry, enzyme activities, visceral organ weights, and immune response of commercial broilers challenged with Esc

10. Frequency of zoonotic bacteria among illegally traded wild birds in Rio de Janeiro
Abstract The illegal wildlife trade may increase the risk of infectious disease transmission, and it may not only cause disease outbreaks in humans but also threaten livestock, native wild populations, and ecosystems' health. Bird species may act as carriers in the transmission of enteric pathogens. However, epidemiological studies on zoonotic bacteria in wi

11. Effects of the encapsulation of usnic acid into liposomes and interactions with antituberculous agents against multidrug-resistant tuberculosis clinical isolates
Mycobacterium tuberculosis (Mtb) has acquired resistance and consequently the antibiotic therapeutic options available against this microorganism are limited. In this scenario, the use of usnic acid (UA), a natural compound, encapsulated into liposomes is proposed as a new approach in multidrug-resistant tuberculosis (MDR-TB) therapy. Thus the aim of this st

12. Monoterpene isolated from the essential oil of Trachyspermum ammi is cytotoxic to multidrug-resistant Pseudomonas aeruginosa and Staphylococcus aureus strains
Abstract INTRODUCTION: The aim of this study was to determine whether an herbal extract containing monoterpene exhibited activity against multidrug-resistant Staphylococcus aureus and Pseudomonas aeruginosa isolated from clinical infection samples. METHODS: The essential oil of Trachyspermum ammi (L.) Sprague ex Turrill (Apiaceae) fruit was extracted by
