Rapid detection and quantitative estimation of type A botulinum toxin by electroimmunodiffusion.
An experimental system is described for the detection and quantitative estimation of type A botulinum toxin by electroimmunodiffusion. The method is shown to be rapid, specific, and quantitative. As little as 14 mouse LD(50) per 0.1 ml of type A toxin was detected within 2 hr. When applied to experimentally contaminated foods such as canned tuna, pumpkin, spinach, green beans, and sausage, the ...

Bacteriol. 86:1308-1313. 1963.-A procedure for the production and isolation of type B staphylococcal enterotoxin in yields up to 4 mg per liter of toxic culture is presented. Staphylococcus aureus S6 was grown in shake flask cultures at 37 C for 24 hr in a ...
متن کاملDetection of Staphylococcal Enterotoxin in Food.
Methods are described for the extraction and serological detection of trace amounts of enterotoxins A and B in foods incriminated in outbreaks of staphylococcal food poisoning. Evidence is presented for the probable applicability of the methods for the detection of unidentified enterotoxins.
متن کاملRapid quantitative serological assay of staphylococcal enterotoxin B.
A simple, rapid method, based on the Oudin single diffusion technique, is described for the quantitative assay of staphylococcal enterotoxin B. The method yields reproducible results without close control of such assay variables as temperature, antiserum dilution, and assay time, provided that the ionic strength is maintained above 0.2 n sodium chloride equivalent.
متن کاملNeutralization of Staphylococcal enterotoxin B by aptamer
12 Staphylococcal enterotoxin B (SEB) is a major virulence factor for 13 Staphylococcal toxic shock syndrome (TSS). SEB activates a large subset of the T 14 lymphocytic population, releasing pro-inflammatory cytokines. Blocking 15 SEB-initiated toxicity may be an effective strategy for treating TSS. Using a 16 systematic evolution of ligands by exponential enrichment (SELEX) process, we 17 iden...
