Pentaplex PCR assay for detection of hemorrhagic bacteria from stool samples.

Diarrheal diseases cause illness and death among children younger than 10 years in developing countries. Conventional testing for the detection of hemorrhagic bacteria takes 2 to 5 days to yield complete information on the organism and its antibiotic sensitivity pattern. Hence, in the present study, we developed a molecular-based diagnostic assay that identifies common hemorrhagic bacteria in stool samples.

Rapid detection of methicillin-resistant Staphylococcus aureus by a newly developed dry reagent-based polymerase chain reaction assay.

Background/purpose: Methicillin-resistant Staphylococcus aureus (MRSA) is a major pathogen responsible for significant numbers of nosocomial and community-acquired infections worldwide. Molecular diagnosis for MRSA nasal carriers is increasingly important for rapid detection and screening of MRSA colonization because the conventional methods are time consuming and labor intensive. However, conventional polymerase chain reaction (PCR) tests still require cold-chain storage as well as trained personnel, which makes them unsuitable for rapid high-throughput analysis.
