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...
The simultaneous amplification of multiple regions of a DNA template is routinely performed using the polymerase chain reaction (PCR) in a process termed multiplex PCR. A useful strategy involving the design, testing, and optimization of multiplex PCR primer mixtures will be presented. Other multiplex design protocols have focused on the testing and optimization of primers, or the use of chimer...
AIM To conduct developmental validation studies on a polymerase chain reaction (PCR) based short tandem repeat (STR) multiplex typing system, developed for the purpose of genetic individualization and parentage testing in domestic cat samples. METHODS To evaluate reproducibility of the typing system, the multiplex was amplified using DNA extracted from hair, blood, and buccal samples obtained...
BACKGROUND At least six HCV (hepatitis C virus) genotypes are unequally distributed worldwide. HCV genotyping guides the selection of treatment regimens and provides important epidemiological markers that enable the outbreak source to be traced and the spread of disease to be controlled. In Egypt, there is an increasing need for cost-effective, fast, and easily performable HCV genotyping assays...
Simultaneous quantification of four RNA targets by multiplex, real-time RT-PCR without optimization.
Researchers carrying out quantitative, multiplex, realtime PCR and RT-PCR require master mixes that provide accurate, simultaneous quantification of multiple targets in the same reaction without time-consuming optimization. Our results at Wyeth Research show that QuantiTect® Multiplex Kits from QIAGEN are well suited for multiplex analysis of up to four RNA targets in two-step and onestep real-...
در این مطالعه واکنش rt-pcr برای تشخیص ویروس در نمونه های کلینیکی به کار گرفته شد. در نمونه های مثبت قطعه ای از ژن b2 ویروس به طول 131 جفت باز تکثیر گردید. در طی یکسال از 12 نمونه کلینیکی که از کانونهای بیماری در استان آذربایجان شرقی جمعاوری شده بود تعداد 10 نمونه حاوی ویروس تب برفکی تشخیص داده شد در آزمایش multiplex-pcr برای تشخیص سروتیپ این ویروسها، مشخص گردید که از این تعداد 4 نمونه از سروتیپ...
تکنیک های مولکولی مانند واکنش زنجیره ای پلیمراز (pcr) روش تشخیصی سریع و قابل اعتماد برای شناسایی پاتوژن های میکروبی می باشند. در دهه¬های اخیر در پی درمان آنتی¬بیوتیکی، سودوموناس آئروژینوزا به عنوان یکی از مهم¬ترین پاتوژن بیمارستانی شناسایی شده است که باعث عفونت¬های حاد و مزمن در افراد بستری در بیمارستان می¬شود. بسیاری از روش های تشخیصی بر اساس pcr برای شناسایی سودوموناس آئروژینوزا توسعه یافته ا...
shigella species are among the common causes of bacterial diarrhoeal diseases. traditional detection methods are time-consuming resulting in delay in treatment and control of shigella infections thus there is a need to develop molecular methods for rapid and simultaneous detection of shigella spp. in this study a rapid multiplex pcr were developed for simultaneous detection of three pathogenic ...
introduction: awareness of the species of shigella has particular importance in the way of dealing with an outbreak, controlling it, and treating patients. the purpose of this study was to use the multiplex pcr method and comparison with the culture method to detect shigella species, as well as analysing the antibiotic resistance pattern in its different species. methods: simultaneously, the fe...
the present study was designed to investigate the prevalence of salmonella species, their molecular characterization and antibiotic resistance in backyard chickens. a total of 1125 samples were collected from backyard chickens in two consequent samplings. in the first part, samples were included of 820 poor recently hatched chicks, hatching residuals, egg shells in the nest floor, cloacal swabs...
