While the Lancefield whole blood killing assay is named after the renowned streptococcal researcher Rebecca Lancefield, the protocol was first described by Todd in 1927 (Br J Exp Pathol 8:1-5, 1927). Initially, the assay was used to identify novel Group A Streptococcal (GAS) serotypes through the supplementation of non-immune human blood (often from infants) with type-specific antisera prepared in rabbits (Lancefield, J Exp Med 106:525-544, 1957; Maxted, Br J Exp Pathol 37:415-422, 1956) and to demonstrate the impressive longevity of type-specific immunity in patients following invasive GAS infection (Lancefield, J Exp Med 110:271-292, 1959). The modern assay is routinely used to screen defined GAS mutants (Wessels, Bronze, Proc Natl Acad Sci U S A 91:12238-12242, 1994; Zinkernagel et al., Cell Host Microbe 4:170-178, 2008) or transposon libraries (Le Breton et al., Infect Immun 81:862-875, 2013) for enhanced susceptibility to opsonophagocytic killing or to screen vaccine antisera (Salehi et al., mSphere 3:e00617-e00618, 2018) or other serological preparations (Reglinski et al., Sci Rep 5:15825, 2015) for anti-streptococcal activity.
虽然 Lancefield 全血杀伤测定法是以著名的链球菌研究人员 Rebecca Lancefield 的名字命名的,但该方案最初是由 Todd 在 1927 年描述的(Br J Exp Pathol 8:1-5, 1927)。最初,该测定法用于通过用兔制备的针对特定类型的抗血清(通常来自婴儿)补充非免疫的人类血液(Lancefield,J Exp Med 106:525-544, 1957;Maxted,Br J Exp Pathol 37:415-422, 1956)来鉴定新型 A 组链球菌(GAS)血清型,并证明侵袭性 GAS 感染后患者针对特定类型的免疫具有令人印象深刻的持久性(Lancefield,J Exp Med 110:271-292, 1959)。现代测定法通常用于筛选特定的 GAS 突变体(Wessels,Bronze,Proc Natl Acad Sci U S A 91:12238-12242, 1994;Zinkernagel 等人,Cell Host Microbe 4:170-178, 2008)或转座子文库(Le Breton 等人,Infect Immun 81:862-875, 2013),以筛选对调理吞噬杀伤作用敏感的突变体,或筛选疫苗抗血清(Salehi 等人,mSphere 3:e00617-e00618, 2018)或其他血清学制剂(Reglinski 等人,Sci Rep 5:15825, 2015)的抗链球菌活性。
