Serological Analysis of Serogroup Icterohaemorrhagiae Using Monoclonal Antibodies

Abstract

Eighteen serovars (19 strains) of serogroup Icterohaemorrhagiae were serologically analyzed using 18 monoclonal antibodies against serovar copenhageni Shiromizu, M20 and serovar icterohaemorrhagiae RGA strains. The reaction patterns of the serovars against these monoclonal antibodies were different. According to these results, we divided the serovars, except for serovar tonkini, into the following three subgroups: Subgroup 1 reacted to many monoclonal antibodies including serovars ictero-haemorrhagiae., copenhageni, hualien, monymusk, mankarso, and budapest. Subgroup 2 fell between subgroups 1 and 3 including serovars dakota, naam, bog-vere, birkini, smithi, ndambari, gem, ndahambukuje and mwogolo. Subgroup 3 reacted to only a few monoclonal antibodies: serovars weaveri and sarmin. © 1985, IEEE. All rights reserved.
