Identification of Salmonella serotypes is important for understanding the environmental diversity of the genus Salmonella. This study evaluates the diversity of Salmonella isolates recovered from 165 of 202 Central Florida surface water samples and investigates whether the serotype of the environmental Salmonella isolates can be predicted by a previously published multiplex PCR assay (S. Kim, J...

Copying multiple regions of a DNA molecule is routinely performed today using the polymerase chain reaction (PCR) in a process commonly referred to as multiplex PCR. The development of a multiplex PCR reaction involves designing primer sets and examining various combinations of those primer sets and different reaction components and/or thermal cycling conditions. The process of optimizing a mul...

Institute for Molecular Genetics, Baylor College of Medicine, Houston, Texas 77030 Ever since it was shown that PCR could simultaneously amplify multiple loci in the human dystrophin gene, (1) multiplex PCR has been firmly established as a general technique. A short list of multiplex PCR applications now includes pathogen identification, gender screening, linkage analysis, forensic studies, tem...

Background: Paratuberculosis and tuberculosis (TB) caused by Mycobacterium avium paratuberculosis (MAP) and Mycobacterium tuberculosis complex (MTC), respectively are economically important, chronic debilitating diseases affecting the dairy herds and are also potential zoonotic threats. Aims: Differential diagnosis of paratuberculosis and TB i...

A traditional nested reverse transcription-polymerase chain reaction (RT-PCR) assay specific for eastern equine encephalomyelitis (EEE) virus was designed to multiplex with a previously described West Nile (WN) virus nested RT-PCR assay. Differentiation of EEE and WN was based on base pair size of the amplified product. One hundred fifty-seven mammalian and avian brain tissues were tested by EE...

clostridium perfringens is an important cause of bacterial food poisoning worldwide. the disease is caused by c. perfringens enterotoxin (cpe) encoded by cpe gene. the aim of this research was to identify the different types of c. perfringens and the presence of cpe gene in isolated bacteria from broilers’ meat marketed in retail meat shops of mashhad city in northeastern of iran. after isolati...
