The bacterial flora of the Men of Kendo (the fencer wears a helmet and mask in the Japanese fencing)has received little attention. Bacteriological examinations were carried out to get information about bacteria on the Men of Kendo in the Nippon Sport Science University during the four seasons. Forty five strains of typical bacteria istlated from the Men of Kendo were rapidly identified with a Gram-Positive and Negative Identification card used in conjunction with the Auto Microbic system. The isolates were distributed in the 17 genera, Bacillus, Flavimonas, Chryseomonas, Actinobacillus, Stenotrophomonas, Corynebacterium, Comamonas, Flavobacterium, Micrococcus, Pasteurella, Pantoea, Pseudomonas, Vibrio, Eikenella, Sphingobacterium, Staphylococcus and Acinetobactor. We found that these bacteria were non-pathogenic bacteria which are often found on the Men of Kendo. Its main constituent were Staphylococcus saprophyticus and Micrococcus luteus, which were followed by Bacillus sphaericus. Results obtained in the successive isolation trials showed that Micrococcus luteus as in figure 1 is typical bacteria of the Men during the four seasons. However, Staphylococcus epidermidis, Staphylococcus capitis, Staphylococcus hominis, Staphylococcus haemolyticus, Pseudomonas stutzri, Bacillus subtilis and Bacillus cereus strains have recently been noticed as the bacteria of opportunistic infections in the clinical medicine.
