Abstract
Inoculation of trachoma material into the testicle of guinea pig gave, in serial passage, a positive result in 9 strains out of 31 ones. That is, an orchitis occured respectively. In the majority of cases the inflammation of testicle was not so serious: the tunica vaginalis and the parenchyma were slightly hyperemic and edematous.
The inflammatory testicle is excised, ground down sufficiently and suspended in saline solution. The suspension is frozen and melted in freezing mixture several times, and after it is centrifuged at 4, 000 rpm for 30 minutes, the supernatant fluid is employed as antigen.
The agglutination tests were performed in 37 cases of trachoma and 20 cases of non-trachoma. The tests proved positive in 20 cases (54%) of trachoma and 1 case (5%) of non-trachoma. If explained in detail, in 31 cases of stadium I and II of trachoma 26 cases (64.5%) were positive, in 29 cases of stadium I 19 cases (65.5%) positive, in 20 cases of granular tarchoma 16 cases (80%) positive.
Therefore, it is the author's judgement that the agglutination is of specific reaction for the serum of trachoma patient.
