Phenotypic and Genotypic Analysis of In Vitro Selected Artemisinin-Resistant

Phenotypic and genotypic analysis of in vitro-selected artemisinin-resistant progeny of Plasmodium falciparum.

Emergence of artemisinin resistance in Cambodia highlights the importance of characterizing resistance to this class of drugs. Previously, intermediate levels of resistance in Plasmodium falciparum were generated in vitro for artelinic acid (AL) and artemisinin (QHS). Here we expanded on earlier selection efforts to produce levels of clinically relevant concentrations, and the resulting lines w...

Evaluation of Phenotypic and Genotypic Expression of Efflux Pumpin Clinical Isolates of Acinetobacter baumannii Resistant to Ciprofloxacin and Gentamicin

Introduction: Acinetobacter baumannii is an important bacteria because of high ability to obtain antibiotic resistance genes and creation of multi-drug resistant strains (MDR). Today, the active efflux pumps has been suggested as one of the most important mechanisms of intrinsic and acquired resistance of antibiotics in bacteria. The aim of this study was Evaluation of phenotypic and genotypic ...

Biofilm Formation in Staphylococcus Aureus and its Relation to Phenotypic and Genotypic Criteria

Abstract Background and Objective: Biofilm is a complex microbial community embedded in a self-produced extracellular polymeric matrix. We aimed to study the extent of biofilm formation by S. Areas isolates and its relation to some phenotypic and genotypic criteria. Material and Methods: One hundred-fifty strains of Staphylococcus aureus isolated from Gorgan were studied. Microtiter plate a...

Phenotypic and Genotypic Detection of Metallo-Beta-Lactamases in Carbapenem Resistant Acinetobacter baumannii

Phenotypic and Genotypic Characteristics of Methicillin-Resistant Staphylococcus aureus Isolated from Dairy and Meat Products in Iran

Background: Methicillin-Resistant Staphylococcus aureus (MRSA) plays an important role in gastrointestinal diseases. The goal of this research was to determine phenotypic and genotypic characteristics of MRSA isolated from dairy and meat products in Iran. Methods: Ninety-three S. aureus isolates were prepared which had been obtained in our previous study. Antimicrobial susceptibility testing w...
