“…However, the question arises as to whether strains which are able to produce SEF in broth also produce the toxin under other conditions. It is known that enterotoxin production of S. aureus under anaerobic conditions is much reduced (Baird-Parker, 1971). Under strict anaerobic conditions we found that SEF producing S. aureus strains failed to produce this toxin in vitro (results not presented).…”

SummaryEnterotoxin production by strainsof Staphylococcus aureusisolated from clinical specimens of human and animal origin and from healthy human carriers was investigated. All nine patients admitted to hospital with symptoms of toxic shock syndrome (TSS) yielded enterotoxin-producing strains ofS. aureus. Eight of these produced staphylococcal enterotoxin F (SEF). A significantly smaller proportion of strains (42% of 50 strains tested) isolated from other clinical specimens of hospitalized patients produced SEF. Production of SEF by strains isolated from clinical specimens of animal origin (48 strains) was not observed. Twenty-nine per cent of 24S. aureusstrains isolated from noses of hospital staff produced SEF. This result was not significantly different from that obtained from strains isolated from clinical specimens other than TSS. A similar percentage of strains isolated from healthy human carriers outside hospital produced SEF (25% of 24 strains tested).The results indicated that enterotoxin production, especially that of SEF. is associated withS. aureusisolated from patients suspected of TSS. There was no indication of an association betweenS. aureusisolated from other staphylococcal infections and SEF production.All strains were phage typed and 79%, of the strains belonging to the international phage-group I produced SEF. All strains lysed by phage 187 were found to produce SEF.

“…Enterotoxins are single, unbranched water-soluble peptides (M.W. 30,000-35,000) that cause gastroenteritis by acting on the intestines (Baird-Parker, 1971; Minor and Marth, 1972). To date, there are 8 sero logically different enterotoxins identified.…”

“…Because the toxin causing the syndrome is produced outside the body, food poisoning caused by S. aureus is classified as a food intoxication (Minor and Marth, 1972) . The minimum number of cells needed to produce a sufficient quantity of enterotoxins to cause food poisoning is generally agreed to be >10^ cells/g (Baird-Parker, 1971; Barber and Deibel, 1972;Genigeorgis et a2., 1971a). Optimum conditions for the pro duction of all enterotoxin types include: 1) a pH in the range of 6.U to 8.0, 2) a temperature of 37 to 40°C, 3) an Aw greater than 0.94, and 4) an environment of high Og tension (Jay, 1978).…”

“…Conditions favorable for the production of specific enterotoxins differ depending on the type of enterotoxin being produced (Minor and Marth, 1972) . Not all strains of S. aureus are capable of producing enterotoxins or are enterotoxigenic (Baird-Parker, 1971) . On the other hand, many enterotoxigenic staphylococci are able to produce more than one type of enterotoxin (Gilbert and Wieneke, 1973;Payne and Wood, 1974).…”
