Ferrets which had been orally dosed with 5 mg of Staphylococcal
enterotoxin B (SEB) responded with an increase in subcutaneous temperature. At 75 min, the subcutaneous temperature was significantly higher (+ 0.9°C ± 0.38°C, P < 0.007) than
in control animals. Animals dosed with 1 or 2 mg of SEB responded with
a small, but not significant, increase in subcutaneous temperature. All
of the animals dosed with 5 mg of SEB retched and vomited. The mean latency for the onset of retching was 105 ± 36 min, and the mean latency for the onset of vomiting was 106 ± 34 min. The mean
number of retches was 17.8 ± 19.6, and the mean number of vomits
was 2.0 ± 1.5. These findings indicate that ferrets can be used
as alternatives to primates for the study of the biological activities of SEB.
