Abstract

A peptide cocktail derived from the mycobacterial antigens ESAT-6, CFP-10, and Rv3615c allowed differentiation between Mycobacterium bovis-infected and M. bovis bacillus Calmette-Guérin (BCG)-vaccinated cattle when used as a skin test reagent for a "DIVA" test (i.e., a test capable of differentiating infected and uninfected vaccinated animals). Addition of the antigen Rv3020c improves the diagnostic sensitivity without compromising specificity in the face of BCG or Johne's disease vaccination.

摘要

一种源自分枝杆菌抗原ESAT-6、CFP-10和Rv3615c的肽混合物,当用作“鉴别感染与疫苗接种动物”(DIVA)试验(即一种能够区分感染动物和未感染的接种疫苗动物的试验)的皮肤试验试剂时,可区分感染牛分枝杆菌的牛和接种卡介苗(BCG)的牛。添加抗原Rv3020c可提高诊断敏感性,同时在面对卡介苗接种或副结核菌素病疫苗接种时不影响特异性。
