The Micro Flocculation Test of Eagle in Syphilitic White Mice

Abstract

Summary and Conclusions

In a study of the micro Eagle test on the sera of 57 syphilitic white mice, we found that: (1) of 28 mice infected 30 days, none was positive; (2) of 47 mice infected 60 days 2 or 4.3% were positive; and (3) of 38 mice infected 120 days 1 or 2.6% was positive. These findings confirm those of other authors; namely, that a positive serologic test for syphilis infrequently occurs in the syphilitic mouse and is, therefore, of no value in studying the course of experimental syphilis in this animal.
