Abstract Salmonella is a bacterium associated with food contaminated by various animals, primarily poultry. Interest and research on bacteriophages are increasing because they can be used as an alternative against antibiotic resistance. In our study, eight ‐specific lytic were isolated from chicken feces. Two of the phages (AUFM_Sc1 AUFM_Sc3) chosen for their characterization due to broader host range. Based morphological genomic analysis, AUFM_Sc1 was identified close similar Enterobacteria...
Surfactants are chemical products widely used in our daily life toothpaste and other personal hygiene cosmetic products, several industries. Biosurfactants surfactants of biological origin that can be produced by microorganisms have many advantages, such as low toxicity high biodegradability, compared to synthetic counterparts. Unfortunately, production costs limit the use biosurfactants. Low-cost is most important factor for biosurfactants able compete global market place. This review...
The aim of this study was to investigate and compare in detail both the antifungal activity vitro (with planktonic biofilm-forming cells) essential oil composition (EOs) naturally growing (OMN) cultivated (OMC) samples Origanum majorana L. (marjoram). analyzed using GC-MS. major constituent EOs carvacrol: 75.3% 84%, respectively. Both oils showed high against clinically relevant Candida spp. with IC50 IC90 less than or equal 0.5 µg mL-1 inhibition biofilm a concentration 3.5 less. Cultivated...
One Health is a unified approach that aims to sustain and maintain the health of humans, animals ecosystem. The environment plays an important role in spread resistance genes, as it unlimited source antimicrobial genes. Escherichia coli can acquire genes from its environment. Extended-spectrum beta-lactamase (ESBL)-producing E. global concern because hydrolyse many beta-lactam antibiotics. In this study, aim was isolate faeces soil samples collected cattle, sheep poultry three districts...
The aim of this study was to increase rhamnolipid production by formulating media using kefir and fish meal for Pseudomonas aeruginosa strains isolated from different environmental resources. strains, named as H1, SY1, ST1, capable were soil contaminated with wastes originating olive oil factories. Additionally, P. ATCC 9027 strain, which is known producer, included in the study. Initially, determined Mineral Salt Medium (MSM) then prepared meal. obtained rhamnolipids purified quantified...
When the problem with carbapenem-resistant Enterobacteriaceae (CRE) increases, older antimicrobial agents such as colistin and fosfomycin are used for treatment of these infections. In this study, broth microdilution method agar dilution were a total 147 multidrug-resistant (MDR) or extensively drug-resistant (XDR) strains CRE. The study included Klebsiella pneumoniae (91.16%), Escherichia coli (7.48%), Enterobacter cloacae (0.68%), Serratia marcescens (0.68%). All produce various types...
Abstract Multidrug‐resistant strains of Acinetobacter baumannii cause major nosocomial infections. Bacteriophages that are specific to the bacterial species and destroy bacteria can be effectively used for treatment. In this study, we characterized lytic bacteriophages A. strains. We isolated from environmental water samples then investigated their morphology, host range, growth characteristics, stability, genome analysis, biofilm destruction on catheter surface. Our results showed efficacy...
There has been an increased interest in essential oils during recent years accordance with new treatments against pathogens. The aim of the present study was to investigate contents and compare antimicrobial activity different brands commercial two natural cinnamon obtained from barks. Antibacterial antifungal were estimated using disc diffusion macro dilution methods Enterococcus faecalis ATCC 19433, 29212, Escherichia coli 25922, 35218, Staphylococcus aureus 29213, 25923, methicillin...
Summary Bacteria adherence to the surface and resulting biofilm have serious harmful effects in food. Biofilm formation foods can lead food deterioration disease transfer easily. Some alternative applications are being tried remove biofilms. Among these, biosurfactants bacteriophages promising owing their low toxicity, easy availability, high activity. In our study, action of phage rhamnolipid, a biosurfactant, on Salmonella Infantis, which is an important pathogen food, was examined....
This study applied two phenotypic tests, namely "Carbapenemase Nordmann-Poirel" (CarbaNP) test and "Carbapenem Inactivation Method" (CIM), against the isolates carrying carbapenem resistance genes. The included 83 carbapenem-resistant Enterobacteriaceae producing oxacillinase-48 (OXA-48) 30 carbapenem-sensitive isolates. Out of total studied, 77 (92.77%) were identified as Klebsiella pneumoniae six (7.23%) Escherichia coli by Matrix Assisted Laser Desorption Ionization-Time Flight Mass...
Background: Biosurfactants are biological origin surfactants, produced by microorganisms and reduce surface interfacial tension between liquids solids. They have many outstanding properties, such as lower toxicity, biodegradability, selectivity specific activity at extreme conditions, compared with synthetic ones. Despite all these positive features high production cost prevents the widespread use of biosurfactants active substances. So using low material wastes, is important for reducing...
Objective: The genotypic analysis of the strains can provide information to evaluate genetic relationships among and epidemiological investigations, it is crucial for monitoring their circulation in different geographic regions. This study was aiming identify similarities or dissimilarities clinical Acinetobacter baumannii (A. baumannii) isolates from four hospitals. Result Discussion: In this study, 78 non-duplicate A. were received patients critical care units. colistin MIC values 24...
Accurate identification of viridans group streptococci (VGS) frequently encountered as a causative agent infective endocarditis is always challenge for the clinical microbiology laboratory. Clinical laboratories generally use semi automatic/full automatic systems, molecular methods and also conventional these bacteria. There are recent published studies that have used MALDI-TOF (Matrix Assisted Laser Ionization Mass Spectrometry-Time Flight) systems in VGS. The aim study was to compare...
Determination of treatment protocols for infections according to antimicrobial susceptibility test (AST) results is are important controlling the problem antibiotic resistance. Two standards widely used in world. One them Clinical Laboratory Standards Institute (CLSI) Turkey many years and other European Committee on Antimicrobial Susceptibility Testing (EUCAST) which Union member countries came into use 2015 Turkey. Since EUCAST had higher clinical sensitivity limits particularly...
Chemical investigation of secondary metabolites in crude methanol extract a solid rice medium marine-derived fungus, Rhizopus oryzae, has enriched the metabolic profile this genus by affording three mycophenolic acid derivatives recognized as new fungal trivially named penicacids H-J (1-3), along with two known naphtho-γ-pyrone dimers, asperpyrone A (4) and dianhydroaurasperone C (5). Structure elucidation isolated compounds was unambiguously determined based on extensive 1D 2D NMR...
Purpose: To determine the efficacies of three commercially available new generation disinfectants against some bacteria and yeast.Methods: Three disinfectant (0.2 % chlorine dioxide, 0.3 dioxide 50 hydrogen peroxide-stabilized by colloidal silver) were screened for their antimicrobial activity Escherichia coli ATCC 25922, Klebsiella pneumonia RSKK 574, Pseudomonas aeruginosa 9027, Enterococcus faecalis 29212, Staphylococcus aureus 25923, S. 43300 (methicillin resistant), epidermidis 12228...
