Detection of Clostridium proteoclasticum and closely related strains in the rumen by competitive PCR

Article Abstract:

A competitive polymerase chain reaction (PCR) procedure which detects the proteolytic bacterium Clostridium proteoclasticum and these closely related Butyrivibrio fibrisolvens strains directly from the rumen was developed. The cPCR approach is found to be an easy and accurate method of bacterial quantitation. It was also found to be useful in quantifying ruminal bacterial populations in vivo.

Detection of Salmonella enterica serovar Typhimurium by using a rapid, array-based immunosensor

Article Abstract:

Research discuses the results of a rapid, multianalyte array biosensor testing of Salmonella in food samples and the test's usage in preharvest testing of chickens for Salmonella infection. Results indicate that that the detection limit of the test is 8 X 10(sup)4 CFU/milliliter.
