[ 1 ] - Bacterial diversity determination using culture-dependent and culture-independent methods
Mud volcanoes are taken into consideration by geologists and oil industry experts have given their association with oil and gas reserves and methane greenhouse gas production in hydrosphere and atmosphere. Gomishan mud volcano phenomenon in the southeastern edge of the Caspian Sea, given its oil and gas resources, has been studied by some geologists in terms of geology and tectonics but not in ...
[ 2 ] - Antibacterial Activity of the Peptide Microcin J25 Produced by Escherichia coli
Background and objectives: Bacteriocins are generally active antimicrobial peptides effective against bacteria closely related to the producer. Escherichia coli produce two bacteriocins: colicins and microcins. Microcin J25 (Mcc J25) is an antibacterial peptide that inhibits bacterial transcription by disrupting the nucleotide-uptake channel of bacterial RNA polymerase. The objective of this st...
[ 3 ] - Determining frequency of Escherichia coli producing beta lactamase CTX-M and SHV in hospital and non-hospital clinical specimens in Isfahan
Background and aim: Antimicrobial resistance is a worldwide problem causing health threats. Escherichia coli is one of the most important bacteria that causes resistance problems. The aim of this study was to evaluate the frequency of Escherichia coli, a extended spectrum beta-lactamase producing CTX-M and SHV, in hospital and non-hospital clinical specimens in Isfahan. Methods: In this stu...
