polymerase chain reaction based serotyping of pathogenic bacteria in food
Journal of Microbiological Methods, 2015Co-Authors: Joelle K Salazar, Yun Wang, Hui Wang, Wei ZhangAbstract:Serotyping analysis of bacterial pathogens in food products is important for foodborne disease surveillance and outbreak investigations. Traditional immunological techniques are labor-intensive and time-consuming, whereas polymerase chain r eaction (PCR)-based techniques are more robust, consistent and rapid. PCR-based methods also provide easier standardization and better reproducibility. Here, we summarize some recent developments and Applications of PCR-based serotyping for common foodborne pathogens, and provide a list of available bioinformatics tools for developing PCR-based serotyping assays.

PCR microfluidic devices for dna amplification
Biotechnology Advances, 2006Co-Authors: Chunsun Zhang, Wenling ZhengAbstract:The miniaturization of biological and chemical analytical devices by micro-electro-mechanical-systems (MEMS) technology has posed a vital influence on such fields as medical diagnostics, microbial detection and other bio-analysis. Among many miniaturized analytical devices, the polymerase chain reaction (PCR) microchip/microdevices are studied extensively, and thus great progress has been made on aspects of on-chip micromachining (fabrication, bonding and sealing), choice of substrate materials, surface chemistry and architecture of reaction vessel, handling of necessary sample fluid, controlling of three or two-step temperature thermocycling, detection of amplified nucleic acid products, integration with other analytical functional units such as sample preparation, capillary electrophoresis (CE), DNA microarray hybridization, etc. However, little has been done on the review of above-mentioned facets of the PCR microchips/microdevices including the two formats of flow-through and stationary chamber in spite of several earlier reviews [Zorbas, H. Miniature continuous-flow polymerase chain reaction: a breakthrough? Angew Chem Int Ed 1999; 38 (8):1055-1058; Krishnan, M., Namasivayam, V., Lin, R., Pal, R., Burns, M.A. Microfabricated reaction and separation systems. Curr Opin Biotechnol 2001; 12:92-98; Schneegabeta, I., Kohler, J.M. Flow-through polymerase chain reactions in chip themocyclers. Rev Mol Biotechnol 2001; 82:101-121; deMello, A.J. DNA amplification: does 'small' really mean 'efficient'? Lab Chip 2001; 1: 24N-29N; Mariella, Jr. R. MEMS for bio-assays. Biomed Microdevices 2002; 4 (2):77-87; deMello AJ. Microfluidics: DNA amplification moves on. Nature 2003; 422:28-29; Kricka, L.J., Wilding, P. Microchip PCR. Anal BioAnal Chem 2003; 377:820-825]. In this review, we survey the advances of the above aspects among the PCR microfluidic devices in detail. Finally, we also illuminate the potential and practical Applications of PCR microfluidics to some fields such as microbial detection and disease diagnosis, based on the DNA/RNA templates used in PCR microfluidics. It is noted, especially, that this review is to help a novice in the field of on-chip PCR amplification to more easily find the original papers, because this review covers almost all of the papers related to on-chip PCR microfluidics.

PCR based technology in veterinary parasitology
Veterinary Parasitology, 1999Co-Authors: Robin B GasserAbstract:Abstract DNA technology is having a major impact in many areas of veterinary parasitology. In particular, the polymerase chain reaction (PCR) has found broad applicability because its sensitivity permits enzymatic amplification of gene fragments from minute quantities of nucleic acids derived from limited amounts of parasite material. This paper discusses some recent Applications of PCR-based methods to parasites and highlights their usefulness or potential for those of veterinary importance. The focus is on PCR tools for the accurate identification of parasites and their genetic characterisation, the diagnosis of infections, the isolation and characterisation of expressed genes, the detection of anthelmintic resistance, and mutation scanning approaches for the high resolution analysis of PCR products.
