Abstract

Survey results of 226 stool samples from healthy people collected from four districts in Ho Minh city in 2018 (districts no. 1, 5, 8 and 9) showed that the number of people carrying Salmonella spp. was 12/226 (5.3%). Twelve fecal samples were positive for Salmonella spp. with 15 Salmonella spp. strains isolated. Three of them are S. Indiana (20.0%); S. Typhimurium, S. Rissen and S. Give. Each has two strains (13.3%): 1 strain has serotypes O: 1 and one strains has 9: 1.5 (6.7%). These Salmonella strains belong to the non-typhoid group (the group that causes diarrhea). The Salmonella spp. strains isolated have highest antibiotic resistance to ampicillin, tetracycline, chloramphenicol (80.0%); followed by sulfamethoxazole/trimethoprim (66.7%); nalidixic acid (40.0%); gentamicin, ciprofloxacin, kanamycin (26.7%). Strains resistant to the third generation cephalosporins were found (cefotaxime and ceftazidime). Three of these are resistant to both types of antibiotics (20.0%). No strains resistance to cefoxitin and cosfomycin were detected.
