A simple and rapid method is described for detecting as little as 1 ng each of staphylococcal enterotoxins A, B, and C2 in 100 mL samples of food extracts. Samples were fractionated on copper chelate Sepharose 6B and the recovery of added staphylococ

Staphylococcus aureus growth, thermostable nuclease (TNase) and enterotoxin production in inoculated canned salmon incubated at 22 ± 1°C for 4 d were dependent on the size of inoculum, and on the amount of oxygen present in the headspace; under nit

Macroinvertebrate colonisation of perspex multiplate artificial substrates suspended in the Ohinemuri River, New Zealand, was investigated over a 70‐day period. Community development was examined in terms of the colonisation and extinction rates of

Perspex multiplate artificial substrates were deployed in the Ohinemuri River on two occasions from May to November 1987. A pilot study was conducted to compare the fauna on substrates with that occurring naturally in the benthos, and a second study

Verotoxin (VT), which is immunologically unrelated to VT1 (Shiga-like toxin I), was purified from the culture filtrate of Escherichia coli hemorrhagic colitis serogroup O157:H7 strain 3657 by copper ion chelate affinity chromatography followed by ani

A new simple method for purification of heat-stable enterotoxin from human strain 73081 of Escherichia coli has been developed. The enterotoxin was produced in casamino acid-yeast extract medium by the reverse sac culture method. The purification inv

SummaryThe degradation of DNA after irradiation was determined in Escherichia coli wild type (parent) and three radiation-resistant mutants 1γ, 6γ and 12γ by measuring the loss of radioactivity from cells previously labelled with [3H] thymidine. L

The past thirty years have witnessed the isolation and synthesis in pure form of several compounds (presumably catalysts) which have been demonstrated to affect in different manners the rate at which various chemical changes occur in the cells of the
