Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS) are the most pathogenic and economically important mycoplasma pathogens that infect chickens. The development of rapid and innovative molecular diagnostic techniques is of pivotal importance for their effective control. The aim of the present study was to develop a novel duplex TaqMan real-time PCR assay for the simultaneous detection o...

mycoplasma synoviae (ms) is an important avian pathogen that can cause both respiratory disease and joint inflammation synovitis in poultry, inducing economic losses to the iranian chicken industry especially breeder farms. the aim of this study was to use the ms specific pcr and culture methods in order to detect of m. synoviae from breeder farms where located in tehran province. a total of 47...

We described a DNA microarray-based method combined with bisulphite treatment of DNA and regular PCR to examine hyper-methylation in promoter 1A of APC gene. A set of oligonucleotide probes were designed and immobilized on the aldehyde-coated glass slides for detecting the methylation pattern of 15 selected CpG sites in the region. The methylation status of 30 colorectal tumor samples have been...

Temperature-sensitive (ts+) vaccine strain MS-H is the only live attenuated M. synoviae vaccine commercially available for use in poultry. With increasing use of this vaccine to control M. synoviae infections, differentiation of MS-H from field M. synoviae strains and from rarely occurring non-temperature-sensitive (ts-) MS-H revertants has become important, especially in countries where local ...

Genotyping methods are essential to understand the transmission dynamics of Acinetobacter baumannii. We examined the representative genotypes of A. baumannii at different time periods in select locations in Ohio, using two rapid automated typing methods: PCR coupled with electrospray ionization mass spectrometry (PCR/ESI-MS), a form of multi-locus sequence typing (MLST), and repetitive-sequence...

A standardized molecular test for the detection of Chlamydophila pneumoniae DNA in cerebrospinal fluid (CSF) would assist the further assessment of the association of C. pneumoniae with multiple sclerosis (MS). We developed and validated a qualitative colorimetric microtiter plate-based PCR assay (PCR-EIA) and a real-time quantitative PCR assay (TaqMan) for detection of C. pneumoniae DNA in CSF...

We have developed a highly accurate, low-cost, single-step, mutagenically separated polymerase chain reaction (MS-PCR) method for the determination of angiotensin II type-1 receptor (AT(1)) A1166C gene polymorphism. The genotypes are determined using the microtiter array diagonal gel electrophoresis (MADGE) system. We have compared the MS-PCR method with allele-specific oligonucleotide hybridiz...

conclusions molecular assays in the early stages of the disease could help in elucidating the effectiveness of the mbp as a prognostic factor in ms. methods this study is convergence of three arms including in silico and in vitro (bioinformatics) with the in vivo (experimental). a novel methodology combining molecular techniques was used to confirm the antigenic properties of mbp and study its ...
