An Algerian strain of Salmonella typhi (56/75), resistant to tetracyclines and minocycline has been studied in our laboratory. Conjugation, transduction and spontaneous loss experiments suggest that these resistance characters are mediated by one R plasmid, referred to as pPA4. This "Tb" plasmid is incompatible with plasmids from groups incB (Grindley), com10 (Scavizzi) and inc0 (Datta). These results suggest that incompatibility group B is world-wide distributed.
我们实验室对一株对四环素和米诺环素耐药的阿尔及利亚伤寒沙门氏菌（56/75）进行了研究。接合、转导和自发丢失实验表明，这些耐药特性由一个R质粒介导，称为pPA4。这个“Tb”质粒与来自B族（格林德利）、com10（斯卡维齐）和C族（达塔）的质粒不兼容。这些结果表明B不兼容群在全球范围内分布。
