background and objectives: we developed and evaluated the utility of a quadruplex taqman real-time pcr assay that allows simultaneous identification of vancomycin-resistant genotypes and clinically relevant enterococci. materials and methods: the specificity of the assay was tested using reference strains of vancomycin-resistant and susceptible enterococci. in total, 193 clinical isolates were ...

today, it is nearly 25 years past from investigation of shiga toxigenic escherichia coli (stec) which is able to produce shiga toxins and cause different gastroenteritis. since incidence of gastroenteritis due to stec is increasing, it's necessary to develop rapid, specific and accurate procedures like pcr. in this study, we used pcr method to detect and identify stec in cultures of 55 escheric...

objective: methicillin-resistant staphylococcus aureus is a major cause of nosocomial and community-acquired infections. aminoglycosides are potent bactericidal agents that are often used in combination with either a β-lactam or a glycopeptide, especially in the treatment of staphylococcal endocarditis. the main mechanism of aminoglycoside resistance in staphylococci is drug inactivation by cel...

Escherichia coli (E.coli) is the most important etiologic agent of childhood diarrhea and represents a major public health problem in developing countries. Aim of this work was to investigate the role of diarrheagenic E.coli in Egyptian children below 5 years age using multiplex PCR and to evaluate multiplex PCR in rapid diagnosis of enteric infections caused by diarrheagenic E.coli strains. Re...

Real-time human papillomavirus (HPV) type-specific multiplex PCR assays were developed to detect HPV DNA in specimens collected for the efficacy determination of the quadrivalent HPV (type 6, 11, 16, and 18) L1 virus-like particle (VLP) vaccine (Gardasil). We evaluated the concordance between type-specific multiplex HPV PCR and the widely used, commercially available Roche Linear Array genotypi...

Objective: The study aimed to molecular characterization of Pasteurella multocida local strain using Enterobacterial Repetitive Intergenic Consensus (ERIC), 13 virulence genes and the outer membrane protein (OmpH) gene. Also, development of diagnostic markers by multiplex PCR from investigated genes. Methodology: The ERIC-PCR was used for the detection of the finger print of Pasteurella multoci...

BACKGROUND Characterization of fusion gene transcripts in leukemia that result from chromosome translocations provides valuable information regarding appropriate treatment and prognosis. However, screening for multiple fusion gene transcripts is difficult with conventional PCR and state-of-the-art real-time PCR and high-density microarrays. METHODS We developed a multiplex reverse transcripti...
