Abstract
An agar diffusion method using microtiter plates was used to detect antibodies to the DNases produced by Staphylococcus aureus, S. intermedius, and S. hyicus. Antibodies to DNase from S. aureus were demonstrated in most of the sera from the species investigated, except dogs, only 11% of whose sera were positive. Positive titers to S. intermedius DNase were found in 84% of deg sera, 61% of Icelandic pony sera, 41% of pig sera, 21% of human sera, and 20% of cow sera but in only 2 and 4% of goat and sheep sera, respectively. Although antibodies to DNase from S. hyicus were not found in sera from humans, dogs, goats, or sheep, 84% of sera from pigs and cows and 29% of sera from Icelandic ponies were positive in this respect. The good accordance between the findings from bacteriological investigations performed elsewhere and the results of serologic tests performed in this study indicates that the results obtained with the serological method in this study properly reflect the actual antigenic exposure to and distribution of the three Staphylococcus spp. in animals and humans.
