During the period from 2001 to 2004, a total of 72 isolates of Salmonella enterica serovars: Anatum (n=40), Enteritidis (n=18), Corvallis (n=8), and Typhimurium (n=6), of various origins (mainly food and diarrhoeagenic stool samples), were collected and further characterized by antibiotic resistance, plasmid analysis, and pulsed-field gel electrophoresis (PFGE). Forty-five isolates presented multidrug resistance to antibiotics. Among which one S. enterica serovar Anatum isolate was resistant to 11 antibiotics, and one S. enterica serovar Typhimurium DT104 isolate was resistant to eight antibiotics. Plasmid profiling identified eight plasmid profiles (with 1-5 plasmids) among the isolates, of which one plasmid profile (P01) was predominant. XbaI PFGE analysis revealed the presence of a predominant clone of the four studied Salmonella serovars circulating in Tunisia throughout the years 2001-2004.
在2001年至2004年期间,共收集了72株肠炎沙门氏菌血清型菌株:阿纳托姆(n = 40)、肠炎(n = 18)、科瓦利斯(n = 8)和鼠伤寒(n = 6),来源各异(主要是食品和腹泻性粪便样本),并通过抗生素耐药性、质粒分析和脉冲场凝胶电泳(PFGE)进一步鉴定。45株分离株表现出对多种抗生素耐药。其中一株肠炎沙门氏菌血清型阿纳托姆分离株对11种抗生素耐药,一株肠炎沙门氏菌血清型鼠伤寒DT104分离株对8种抗生素耐药。质粒图谱分析在分离株中鉴定出8种质粒图谱(含1 - 5个质粒),其中一种质粒图谱(P01)占主导。XbaI PFGE分析显示,在2001 - 2004年期间,四种研究的沙门氏菌血清型在突尼斯存在一个占主导的克隆。
