A new diagnostic reagent was developed that is capable of detecting the presence of Clostridium perfringens rapidly and accurately compared to the conventional methods. C. perfringens enterotoxin (cpe) gene is the gene of interest since it encodes the enterotoxin responsible for food poisoning. Two new cpe-specific labeled DNA probes were evaluated using Southern and dot blot hybridization. Bac...
The use of DNA probes for Shiga-like toxin I (SLT-I) and SLT-II for detection of SLT-producing Escherichia coli (SLTEC) in foods and calf fecal samples was evaluated. Enrichment cultures were prepared from food or fecal samples. Colonies formed by plating of enrichment cultures were probed for SLTEC by colony hybridization. Alternatively, enrichment cultures were analyzed for SLTEC presence by ...
Molecular techniques previously used for genome comparisons of closely related bacterial species could prove extremely valuable for comparisons of complex microbial communities, or metagenomes. Our study aimed to determine the breadth and value of suppressive subtractive hybridization (SSH) in a pilot-scale analysis of metagenomic DNA from communities of microorganisms in the rumen. Suppressive...
An improved PCR-based subtractive hybridization strategy was used to clone apoptosis-related genes induced by all-trans retinoic acid (ATRA) from human promyelocytic leukemia cell line HL-60 cells. The protocol used the cap-finder method, long-distance PCR, streptavidin magnetic bead-mediated subtraction and spin column chromatography. Twenty-seven clones related to apoptosis were identified by...
