Abstract

The distribution of plasmids was studied in a representative collection of salmonella strains which comprised 98 Salmonella typhimurium and 96 other serotypes. Plasmids were detected in 72% of strains (mean 1.3 plasmids/strain) and individual strains harboured between 0 and 7 plasmids. They were more common among S. typhimurium than other serotypes (incidence 92 and 53%; mean 1.9 and 0.8 plasmids/strain respectively). Although a higher proportion of S. typhimurium (33%) were antibiotic-resistant compared to other serotypes (14%) the evidence presented indicated that R-plasmids were not responsible for the difference observed in the number and distribution of plasmids in these strains. These results were discussed in comparison with similar studies of Escherichia coli and other enteric genera.

摘要

对一组具有代表性的沙门氏菌菌株进行了质粒分布研究,该组菌株包括98株鼠伤寒沙门氏菌和96株其他血清型菌株。在72%的菌株中检测到质粒(平均每株1.3个质粒),单个菌株携带的质粒数在0至7个之间。它们在鼠伤寒沙门氏菌中比在其他血清型中更常见(发生率分别为92%和53%;平均每株分别为1.9个和0.8个质粒)。尽管与其他血清型(14%)相比,鼠伤寒沙门氏菌中抗生素耐药菌株的比例更高(33%),但所提供的证据表明,R质粒并非造成这些菌株中质粒数量和分布差异的原因。将这些结果与对大肠杆菌和其他肠道菌属的类似研究进行了比较和讨论。
