This depends on the stage of the lactation when the cure occurs. If the infection cures during the dry period, specific antibodies will not be detected, or detection will be below the test cut-off during the next lactation, except for the very early stage of the lactation.  Similarly, if the infection clears during the lactation and inflammation has subsided (as measured by SCC returning to normal levels), S. aureus-specific antibodies are not normally detected during the next herd test in four weeks.
