Abstract

Urease-positive aerobic corynebacteria were isolated from the prepuce of 50 out of 77 (64.9%) healthy hogs and from the bladder, urethra and vaginal vestibule of 3 out of 10 (30.0%) healthy gilts. A total of 93 isolates from the pigs were divided, based on 41 characteristics, into two groups, A and B. Group A bacteria which were similar each other consisted of 67 isolates from the prepuce of hogs and 3 isolates from the bladder and urethra of gilts. Group B contained the remaining bacteria, which showed great diversity of characters. A numerical taxonomic study of group A strains showed that they were similar, with similarity values of more than 92%, and that they were different from the known species of urease-positive aerobic corynebacteria. It is possible that group A bacteria belong to a new species of genus Corynebacterium.
