The incidence of enteritidis serotype of Salmonella enterica in salmonellae infections has steadily increased in Spain from 27.1% in 1982 up to 63.4% in 1987. Given this high incidence, we have studied the plasmid profiles of Enteritidis isolates to subclassify them. Different profiles were observed in 50 isolates. In 13 Enteritidis serotype outbreaks, up to 5 different plasmid profiles were found. Each outbreak correlated with a single plasmid profile except in one case where plasmids of two different profiles were observed in strains from the same outbreak.
在西班牙，肠炎沙门氏菌肠炎血清型在沙门氏菌感染中的发生率从1982年的27.1%稳步上升至1987年的63.4%。鉴于这一高发生率，我们研究了肠炎沙门氏菌分离株的质粒图谱以对其进行亚分类。在50株分离株中观察到了不同的图谱。在13起肠炎血清型暴发中，发现了多达5种不同的质粒图谱。除了在1起暴发中，同一暴发中的菌株观察到两种不同图谱的质粒外，每起暴发都与单一的质粒图谱相关。
