Table 4 MIF antibody titers and SPDs from reciprocal cross-reactions of mouse antisera to the members of the Rickettsia conorii complex.

From: Proposal to create subspecies of Rickettsia conorii based on multi-locus sequence typing and an emended description of Rickettsia conorii

  MIF antibody titer (SPD) of mouse antisera to *:
Antigens R. conorii ITTR AFR isolate A-167 AFR isolate Chad ISFR
R. conorii 1,024 256 (4) 256 (5) 256 (5) 256 (4)
ITTR 512 (4) 2,048 512 (4) 256 (5) 256 (5)
AFR isolate A-167 128 (5) 256 (4) 1,024 512 (2) 256 (4)
AFR isolate Chad 128 (5) 256 (5) 512 (2) 1,024 256 (4)
ISFR 128 (4) 128 (5) 128 (4) 128 (4) 512
  1. * Titers are the reciprocals of the highest dilution of antisera that gave a positive reaction. SPDs are calculated according to the formula given in the Materials and Methods section.
