With fast-growing polymerase chain reaction (PCR) technologies and various application methods, the technique has benefited science medical fields. While having strengths limitations on each technology, there are not many studies comparing efficiency specificity of PCR technologies. The objective this review is to summarize a large amount scattered information focused two majorly used technolog...

conclusions the high prevalence of tet (o) resistance gene along with new detection of tet (a) resistance gene in campylobacter spp. isolated from poultry carcasses revealed an extensive tetracycline resistance among campylobacter isolates from poultry in iran. it emphasized the need for cautious use of tetracycline in poultry production to decrease the extension of tetracycline-resistant campy...

background: enterococci faecalis are predominating species of enterococci causing nosocomial infections. acquisition of resistance to antibacterial agents, and ability to transfer the resistant genes made them clinically important. this study was performed to determine the frequency of isolation of different species of enterococci , and the antibacterial resistance pattern of the isolated speci...

Background: One third of epileptic patients are resistant to several anti-epileptic drugs (AED). P-glycoprotein (P-gp) is an efflux transporter encoded by ATP-binding cassette subfamily B member 1 (ABCB1) gene that excludes drugs from the cells and plays a significant role in AEDs resistance. Over-expression of P-gp could be a result of polymorphisms in ABCB1 gene. We studied the association of...

INTRODUCTION The mosquito Aedes aegypti has evolved resistance to pyrethroid insecticides. The present study evaluated Ae. aegypti from Goiânia for the resistant phenotype and for mutations associated with resistance. METHODS Insecticide dose-response bioassays were conducted on mosquitoes descended from field-collected eggs, and polymerase chain reaction (PCR) was used to genotype 90 individ...

Antibiotic resistance genes in the feces of healthy young adult Japanese were analyzed with polymerase chain reaction using specific primers. Antibiotic resistance genes against macrolides (ermB, ermF, ermX, and mefA/E), tetracyclines (tetW, tetQ, tetO, and tetX), β-lactam antibiotics (blaTEM ), and streptomycin (aadE) were detected in more than 50% of subjects. These antibiotic resistance gene...

background and objectives: klebsiella pneumoniae ( k. pneumoniae ) is an opportunistic microorganism. this study aimed to investigate the presence of mag a gene and antimicrobial susceptibility in k. pneumoniae . materials and methods: 195 clinical specimens were collected from hospitals of shahrekord, iran. bacterial culture, biochemical diagnostic standard test, determination of antibiotic se...

Composite electrodes containing active materials, carbon and binder are widely used in lithium-ion batteries. Since the electrode reaction occurs preferentially in regions with lower resistance, reaction distribution can be happened within composite electrodes. We investigate the relationship between the reaction distribution with depth direction and electronic/ionic conductivity in composite e...
