The purpose of this study was to investigate the biochemical characteristics and antimicrobial susceptibility of Escherichia (E.) coli O157 and verotoxin-producing E. coli isolates from the Northern Kyushu Island and Yamaguchi area of Japan. A total of 54 isolates- 50 E. coli O157, 3 verotoxin-producing E. coli O26 and 1 verotoxin-producing E. coli O111 - were used in this study. Regarding H antigen, H7 type in E. coli O157 accounted for 98% (49/50), and residual 1 strain of E. coli O157 was untypable H type. Two of 3 E. coli O26 isolates were H11 type, residual 1 strain of E. coli O26 was untypable H type, and E. coli O111 isolate was non-motile strain. All 54 isolates were susceptible to cephems, fosfomycin, kanamycin, amikacin and co-trimoxazole. Tetracycline-resistant isolates existed in 13 of all 54 isolates, 5 of those 13 isolates had tetA, and the other 7 isolates had tetB. Eight amoxicillin-resistant isolates had TEM-1 beta-lactamase. Four of the 5 isolates that had tetA also had TEM-1 beta-lactamase. Nalidixic acid and 6 fluoroquinolone used had no insensitive or resistant isolates. Kanamycin-resistant isolates, fosfomycin- and nalidixic acid-insensitive isolates have been reported, so we must notice the antibiogram of such strains. It is important that the surveillance of antimicrobial susceptibility of enterohemorragic E. coli should be continued after this.

Background: We examined the effect of acupuncture for the overactive bladder., Methods: Eleven patients (9 males and 2 females) with the overactive bladder were treated with acupuncture. The age of the patients ranged from 51 to 82 years (mean 71 years). Nine patients complained of urge incontinence and 2 patients of urgency. Uninhibited contraction was observed in all patients before the acupuncture. A disposable needle (0.3 mm in diameter, 60 mm in length) was inserted into bilateral BL-33 points at the depth of 50 to 60 mm and was rotated for 10 minutes manually. The treatment was performed 4 to 12 (average 7 times)., Results: Urge incontinence was controlled completely in 5 and partially in 2 of 9 patients. In 2 patients who complained urgency complete response was obtained after the treatment. Uninhibited contraction disappeared in 6 patients after the treatment. Acupuncture induced an increase of maximum bladder capacity and bladder compliance with statistical significance (p < 0.01 and p < 0.05), respectively., Conclusion: Acupuncture at the BL-33 point was effective for controlling the overactive bladder.
