The urethral discharge was cultured on 87 patients who were suspected as non-gonococcal urethritis by clinical symptoms and Gram`s stain. Among them, H. vaginalis could be cultured and isolated from 9 patients.
The results obtained in this investigation were summarized as follows.
1. The distribution of age showed the highest incidence in 20 to 39 years. The ratio of gonococcal to non-gonococcal urethritis was 1:2.2. The isolated organisms were S. aureus (15 cases), H. vaginalis (9 cases), Streptococcus (8 cases), Diphtheroid (7 cases), S. epidermidis (4 cases), Enterobacter (1 case), Pseudomonas (1 case), Acinetobacter (1 case), and Corynebacterium species (1 case) in order Of their frequency.
2. In group of the patients with H. vaginalis, incubation period was 10 to 20 days in the majority of patients, and there were no clinical symptoms except scanty urethral discharge, and there was no extra-marital sexual relations in 3 patients.
3. Gram (─) bacilli and coccobacilli were found in Gram´s stain. And WBC was found in the counts of less than 10/HPF in 78%.
4. All the H. vaginalis were sensitive to ampicillin and cephlosporin in sensitivity test.
5. The incidence of H. vaginalis urethritis in man corresponded to 7% of all urethritis, and 10% of non-gonococcal urethritis.
