The molecular technique, enterobacterial repetitive intergenic consensus (ERIC)-polymerase chain reaction (PCR) produces genomic DNA fingerprint that discriminate bacterial species and strains. This technique was applied to the characterization of Listeria monocytogenes, an important food-borne pathogen implicated in numerous cases of listeriosis. The(More)
Histamine, the principal causative agent in scombroid food poisoning, was analyzed in seafood by a new, rapid, and sensitive method using capillary zone electrophoresis (CZE) with UV detection at 210 nm. Incurred histamine in methanolic fish extracts migrated within 4 min in a fused silica capillary filled with 0.02 M citrate buffer, pH 2.5, under an(More)
The cephalosporins are a group of structurally related, broad spectrum beta-lactam antibiotics isolated from the mold Cephalosporium. Methods of analysis of cephalosporin antibiotics include microbiological, titrimetric and chromatographic assays. Chromatographic techniques, including high-performance liquid chromatography, have been extensively utilized(More)
The polymerase chain reaction (PCR), a rapid, sensitive technique for amplifying target DNA sequences of pathogenic microorganisms, was used to amplify Clostridium botulinum type E neurotoxin gene fragments in smoked fish. Other botulinal neurotoxin-producing strains, nontoxigenic strains, and food-related microorganisms did not yield nonspecific(More)
Recently, the Northeast Regional Laboratory of the Food and Drug Administration conducted a collaborative study on the method to determine histamine in tuna by capillary electrophoresis. This study, under the guidance of the AOAC International, was the first of its kind involving the use of CE and was undertaken to establish official monograph status. The(More)
