Most people encounter the bacterium Staphylococcus aureus and its toxin staphylococcal enterotoxin type B (SEB) at some point in their lives fi om food (ptomaine) poisoning. Some of these strains of bacteria have been responsible for toxic shock syndrome among women using feminine hygienic products, especially during the peak of the affliction in the early 1980s. 

Representatives of medium-size analytes detected by affinity biosensors based on spectroscopy of guided modes include food-safety related analytes such as staphylococcal enterotoxin B , botulinum toxin, and E. coli... 

Suggested Alternatives for Differential Diagnosis Campylobacteriosis, cryptosporidiosis, cyclosporiasis, E. coli infections, Listeria monocytogenes, shigellosis, Vibrio infections, yersiniosis, ingestion of bacterial toxins such as staphylococcal enterotoxins or botulinum toxin. 

Caution A toxin is a poison produced by a living organism. The middle term of staphylococcal enterotoxin B means a toxin that is produced by microorganisms, such as some staphylococci, and causes gastrointestinal symptoms. 

Biological Agents BACTERIA (Anthrax, Brucellosis, Cholera, Plague, Tularemia). VIRUSES (Crimean-Congo Hemorrhagic Fever, Rift Valley Fever, Smallpox, Venezuelan Equine Encephalitis (VEE), Viral Hemorrhagic Fever (Ebola)). TOXINS (Botulinum, Ricin, Staphylococcal Enterotoxin B (SEB), Trichothecene Mycotoxins/T-2). 

Protein toxins such as botulism, staphylococcal enterotoxin B, or ricin can be separated with gas or liquid chromatography, electrophoresis, or a combination. The pChemLab (Sandia National Laboratories Albuquerque, NM) series of instruments includes a hand-held Bio Detector. Proteins in the sample are labeled with fluorescent tags, and nanoliter volumes of samples are separated by microchannels etched into a glass chip. The separation occurs as the sample moves through the channels and identification is based on retention times. The analyses can be completed within 10 min. 

Molecular weight of the main bacterial toxins ranges from 28,000 to 150,000, which makes it possible for most sensitive SPR biosensors to measure their concentrations directly or using a sandwich assay. Examples of food safety-related toxins detected by SPR biosensors include Botulinum toxin (detection limit 2.5 pg/ml " ), . coli enterotoxin (detection limit 6 pg/ml " ) and Staphylococcal enterotoxin B (detection limit 5 ng/ml and 0.5 ng/ml for direct detection and sandwich assay, respectively" ).

Bacillus cereus exotoxin is produced in the gastrointestinal tract after ingestion of improperly stored boiled or fried rice. B. cereus toxin is thermoresistant, as is staphylococcal enterotoxin. Symptoms of food poisoning occur up to six hours after food ingestion and are not characteristic (Butterton and Claderwood, 2001). 

Detection of staphylococcal enterotoxin B (SEB), a causative agent of food poisoning, was achieved by QDs conjugated with polyclonal sheep anti-SEB antibody.57 Moreover, this approach also harbors the possibility of a multiplexed immunoassay (see Fig. 12.3), which was first reported by Goldman et al.58 in 2004 four toxins of interest in food- or water-borne illnesses (cholera toxin, ricin,...
