To survey on the bacterial cause infected wound and the sensitiveness with antibiotic of isolate microbial strain at surgical department, Can tho General Hospital

Wound infection is one of the most important surgical infection and is a high percentage of hospital infection. In general surgical deparment at Can Tho General Hospital from 2001-2002, 110 samples of wound infection were isolated and tested antibiogram. Total of 133 microbial strains were isolated, multi infection is 19.09%, the highest of number of bacterial strain in a sample is 3. E. coli is the most common isolated (26.34%), Klebsiella sp 16.55%, Staphylococcus aureus: 9.78%. The result of antibiogram showed that among cocci gram positive group, lowest resistance antibiotic are vancomycin (6.24%), ciprofloxacin (55.3%); among bacilli negative group most of antibiotic tested were resistant in more than 50%, antibiotics nearly completely resistant were ampicillin (95.92%) and amoxicillin+clavulanic acid (82.35%), amikacin (75.29%). For Pseudomonas, antibiotica are still good effect are ciprofloxacin (90%), colistin (80%). Pseudomonas are still reristant to other antibiotics (50-70%).

H.pylori infection status in gastroduodenal ulcer patients and primary evaluations of bacterial antibiotic sensibility at Can Tho General Hospital

Study on 100 gastroduodenal ulcer patients treated at Can Tho General Hospital between March and December 2001. Results: the prevalence of gastric ulcer was high (58%), followed by duodenal ulcer (39%) and the prevalence of gastroduodenal ulcer was low (3%). The rate of H.pylori positive was 66.66% in duodenal ulcer patients, 55.17% in gastric ulcer patients. The rate of H.pylori infection was 33.33% in gastroduodenal ulcer patients. H.pylori was still sensitive with amoxicillin (97.29%), tetracycline (94.6%), clarythromycine and erythromycin (72.97%), but was highly resistant with metronidazole (91%).
