Streptococcus pyogenes survives poorly on plain cotton-wool swabs, whereas serum-dipped swabs permit its survival but also allow overgrouth by other bacteria and are likely to contain virus inhibitors. The use of swabs dipped in a solution of 20% bovine albumin (fraction V) and sterilized by steam is therefore recommended, since these permit bacterial survival without growth and are unlikely to contain virus inhibitors.
化脓性链球菌在普通脱脂棉拭子上存活不佳,而浸有血清的拭子虽能使其存活,但也会让其他细菌过度生长,且可能含有病毒抑制剂。因此,建议使用浸有20%牛血清白蛋白(第五组分)溶液并经蒸汽灭菌的拭子,因为这些拭子能让细菌存活但不生长,且不太可能含有病毒抑制剂。
