Sporulation and enterotoxin regulation by sigma factors in Clostridium perfringens
Clostridium perfringens is a leading cause of food poisoning annually in the United States. Ingested C. perfringens vegetative cells respond to the acidic conditions of the stomach by initiating sporulation. The process of sporulation is essential in the formation of an enterotoxin (CPE) that is …

Intervention Strategies to Reduce Foodborne Pathogens in Poultry During Grow-out and Processing
Several foodborne pathogens like Salmonella spp., Campylobacter jejuni and Clostridium perfringens can occasionally be traced to poultry sources. The development of intervention strategies that are applicable to different stages of poultry production can help lessen the level of these pathogens in …

Knowledge, beliefs and attitudes, concerning food hygiene, in children and young adults, in south east Wales
Surveillance statistics show that many food poisoning cases occur in the home and surveys have revealed wide spread ignorance of cross-contamination and temperature control. In this work the food preparation practices of children and young adults (n=267) in south East wales were considered. Regular …

Sensitive Detection of Foodborne E. coli O157:H7 by Dendrimer-aptamer Modified Microchannels - with RCA Signal Intensifications
Foodborne pathogenic bacterial infection is one of the main causes for food poisoning cases. Therefore there is an urgent need for rapid, sensitive and cost-effective detection methods in order to avoid or to respond to outbreaks of such diseases in a timely manner. To this end, a dendrimer-aptamer …
