Antibiotic resistance in human pathogens is a major public health issue. Some of the resistance problem can be attributed to the transfer of resistant bacteria from animals to people and the transfer of resistance genes from animal pathogens and commensal bacteria to human pathogens. Control measures include improvements in food hygiene to reduce the spread of zoonotic bacteria to people via the food chain. However, to specifically address the issue, the medical profession must control misuse and overuse of antibiotics in hospitals and community practice. In addition, the livestock industries and their advisors must reduce and refine the use of antibiotics in animal production and replace antibiotics with alternative disease control measures as much as possible.

On the purpose of epidemiological survey related to foods poisoning, a total of 316 specimens collected from street vended foods in Pusan area were examined for the presence of Campylobacter Jejuni(C. jejuni) and also the isolation rates, biochemical properties and antibiotic susceptibility were investigated. Of the 316 specimens, 13 strain(4.1%) of Campylobacter jejuni were isolated. Isolation rate for each food was 37.5% in gizzard, 4.1% in Korean sausage and 3.9% in kimpop. Isolated C. jejuni were grouped as biotype I(84.6%), II(7.7%) and IV(7.7%). C. jejuni isolated from street vended foods were resistant to cephalothin(100%), penicillin(84.6%) and erythromycin(76.9%), but sensitive to gentamicin(92.3%), kanamycin(84.7%) and chloramphenicol(77.0%).

Objectives : This study is to report the effects of Bangkibokryeong-tang(Fanjifuling-tang(BBT)) on stroke patient with Urinary tract infection.(UTI) Methods : A stroke patient diagnosed as UTI was treated with BBT (防己茯笭湯) at one-month intervals. We observed body temperature, amount of urine and recorded photographs of any changes during the treatment period. Treatment efficacy was assessed using urinary analysis. Results : After the treatment, there was improvement in urine analysis. And the symptoms of UTI and her conditions got better. Conclusion : The report suggests that BBT is effective in controlling various symptoms related to UTI with antibiotic resistance on stroke patient.

Phenazine 1-carboxylic acid (PCA) is an antifungal antibiotic isolated from a culture filtrate of Bacillus sp. B-6 producing an acyl CoA synthetase inhibitor. This antibiotic is reported as an inhibitor of an acyl CoA synthetase from Pseudomonas sp.. Bacillus sp. B-6 was resistant to PCA up to 350 ${\mu}g/ml$. We investigated the mechanism of the resistance of Bacillus sp. B-6 to PCA. The rate of growth in a medium containing up to 100 ${\mu}g/ml$ was as rapid as the PCA-free medium. At a PCA concentration of 300 ${\mu}g/ml$, the growth rate was more than half that of the control. In this work, we purified acyl CoA synthetase from Bacillus sp. B-6 and found that this acyl CoA synthetase was much less sensitive to PCA than the acyl CoA synthetase from other source. These findings suggested that the insensitivity of Bacillus sp. B-6 acyl CoA synthetase plays an important role in the PCA resistance of this bacterium.

In the course of screening for new anticancer antibiotics from myxobacteria, strain JW357 was found to produce an antibiotic that was active against several human cancer cell lines. This strain was identified as Angiacaccus disciformis by morphological and cultural characteristics. The antibiotic produced was identified as myxochelin A. It demonstrated significant cytotoxicity against certain human cancer cells with $IC_{50}$ values ranging 1.15 to $2.36{\mu}g/ml$. Myxochelin A was interestingly as active against multidrug-resistant CL02 cells as against the sensitive parental cells (HCT15).

This study was performed to determine the antibiotic susceptibility profiles of Salmonella spp., coliforms, Listeria monocytogenes, Staphylococcus aureus and Vibrio spp. isolated from broiler carcasses, aquacultured flounders, hamburgers, and lettuce, which are foods consumed in large quantities in Korea. Salmonella spp. and L. monocytogenes were isolated only from broiler carcasses and Salmonella spp. had a high multidrug resistance rate of 61.1%. Meanwhile, coliforms and S. aureus were isolated from all four foods tested in this experiment. The multidrug resistance rate of coliforms from broiler carcasses was 50%, and that of Vibrio spp. from flounders was 71.4%. The resistance to tetracycline, streptomycin, ampicillin or carbenicillin was common regardless of the kind of food or isolate.

This study was conducted to investigate the biochemical characteristics, the population and antibiotic susceptibility test of Clostridium perfringens isolated from intestinal contents of slaughter cattle in Kyung-ju and Po-hang. 1. In slaughter cattle Cl perfringens were isolated from intestinal contents of 51 of 101 cases(50.4%) and the population were $\leq$$10^5$cfu/ml of 44 cases(86.3%). 2. In antibiotic susceptibility test, ampicillin, bacitracin, cephalothin, penicillin polymyxin B were highly susceptible, ohloramphenicol, erythromycin, tetracycline were lowly susceptible, gentamicin, kanamycin, amikacin, streptomycin, sulfamethoxine, sulfamethazine were resistant. 3. In leaving test intestinal contents leaved for 0, 4, 8, 16, 32 hours in room temperature and population of Cl perfringens were gradually increased.

The purpose of this study was to investigate the cause of chronic diarrhea from anaerobic bacteria isolated from Siberian tiger with chronic diarrhea. Major anaerobic bacteria isolated from faces were Clostridium perfringens and their population was $6 {\times} 10^3$ cfu/g feces. Antibiotic sensi- tivity test against Clostridium perfringens was performed using 6 antibiotic drugs including colistin gentamicin, trimethoprim/sulfamethoxazole, amikacin, enofloxacin and penicillin. Clostridium per- fringens were sensitive to amikacin, enrofloxacin and penicillin while they were resistant to colistin. gentamicin and trmetboprim/sulfamethoxazole. And we found that chronic diarrhea of Siberian tiger was treated successfully with penicillin. These results suggested that Clostridium perfringens may bee a cause of chronic diarrhea in Siberian tiger.

A retrospective double blind study comparing 7 day with 2 day regimen of antibiotic prophylaxis was conducted among 200 patients undergoing open heart surgery. No case of endocarditis and wound infection occurred. Pneumonia developed in 5 cases of the 7 day and 1 case of the 2 day group. Urinary tract infection without clinical significance developed in 1 case of the 7 day and 3 cases of the 2 day group. Bacteremia developed in 2 cases of the 7 day and 1 case of the 2 day group. We concluded as follows: l. Administration of antibiotics for 2 days appears to be without substantial risk of infection comparing long term 7 day regimen. 2. 7 days of antibiotics may actually increase the risk of serious infection such as nosocomial pneumonia, and predispose to the development of infections with fungi or antibiotic resistant bacteria. 3. 2 days of prophylaxis is more beneficial than long term 7 day regimen for example economically.

Since many years, continuous low dose antibiotic prophylaxis (CAP) has been used for children at a risk for recurrent urinary tract infection (UTI), especially those with vesicoureteral reflux (VUR). The incidence of recurrent UTI has been shown to be higher in children with VUR with bladder and bowel dysfunction (BBD) than in those with VUR without BBD. Therefore, CAP has been recommended for children with BBD and VUR because of the increased risk of UTI. However, the use of CAP has become highly controversial because of bacterial resistance developed due to antibiotic over-usage. The preventive effects of probiotics have been proved in various adult urogenital infections, and the antimicrobial activities of lactobacilli against uropathogens have been demonstrated in previous in vitro studies. However, a critical assessment of their efficacy in children with UTI is lacking. The importance of the use of urogenital probiotics is that it is a natural approach that replenishes the depleted normal flora to create a better environment to fight off uropathogens. Probiotics have a great potential, particularly today with the increasing threat of antibiotic-resistant microorganisms.
