BACKGROUND In critically ill patients with pneumonia, accurate microorganism identification allows appropriate antibiotic treatment. In patients undergoing bronchoalveolar lavage (BAL), direct examination of the fluid using Gram staining provides prompt information but pathogen identification accuracy is low. Culture of BAL fluid is actually the reference, but it is not available before 24 to 4...
BACKGROUND To date, only influenza and RSV testing are recommended for respiratory viruses' detection in paediatric units. In this study, we described, according to seasons, ages and clinical units, the results obtained in children (<15 years old) by multiplex-PCR (mPCR) tests allowing a quick and wide range detection of all respiratory viruses. These results were also compared with RSV specifi...
mpcr is a stand-alone, exible and eecient implementation of the Chains of Recurrences (CR) method. It can be used interactively, as a network-based server, or as a library. Using the CR method, mpcr evaluates closed-form expressions over regular grids with an unsurpassed eeciency { often hundreds of times faster than comparable programs. In this paper, the main features of mpcr are described, e...
BACKGROUND Genetic testing for Duchenne/Becker muscular dystrophy (DMD/BMD) mutations initially involved multiplex polymerase chain reaction (mPCR), which targeted two mutation hotspots in the gene and detected deletions in affected males. A newer technology, multiplex ligation-dependent probe amplification (MLPA), was introduced for diagnostic testing in 2007. OBJECTIVES To evaluate MLPA rel...
BACKGROUND In Malaysia, Shigella spp. was reported to be the third commonest bacterial agent responsible for childhood diarrhoea. Currently, isolation of the bacterium and confirmation of the disease by microbiological and biochemical methods remain as the "gold standard". This study aimed to detect the prevalence of four Shigella virulence genes present concurrently, in randomly selected Malay...
Avian leukosis virus (ALV) subgroups A, B, and J are very common in poultry flocks and have caused serious economic losses in recent years. A multiplex PCR (mPCR) method for the detection of these three subgroups was developed and optimized in this study. We first designed a common forward primer, PF, and three downstream primers, AR, BR, and JR, which can amplify 715 bp for subgroup A, 515 bp ...
We report the development of a real-time Invader assay combined with multiplex PCR (mPCR-RETINA), an SNP-based approach that can measure the allelic ratio in copy number variation (CNV) regions of a genome. RETINA monitors the real-time fluorescence intensity of each allele during the Invader assay and detects allelic asymmetries caused by genomic duplication/multiplication in heterozygous indi...
Haemophilus parasuis causes Glässer's disease and pneumonia in pigs. Indirect hemagglutination (IHA) is typically used to serotype this bacterium, distinguishing 15 serovars with some nontypeable isolates. The capsule loci of the 15 reference strains have been annotated, and significant genetic variation was identified between serovars, with the exception of serovars 5 and 12. A capsule locus a...
INTRODUCTION: This study aimed to determine the prevalence, and virulence factors of Listeria monocytogenes isolated from various samples by multiplex polymerase chain reaction (MPCR). METHODS: A total of 617 isolates were obtained and MPCR was employed for detection of the inlA, inlC, and inlJ genes. RESULTS: L. monocytogenes was detected in 46 (7.45%) of the 617 specimens. inlA, inlC, a...
Citrus trees harbor a large number of viral and bacterial pathogens. Citrus yellow vein clearing virus (CYVCV), Indian citrus ringspot virus (ICRSV), Citrus yellow mosaic virus (CYMV), Citrus tristeza virus (CTV) and a bacterium, Candidatus Liberibacter asiaticus (CLa) associated with huanglongbing (HLB) disease, the most prevalent pathogens in citrus orchards of different regions in India and ...
