An unusual Salmonella typhimurium hybrid with sensitivity to coliphage lambda and salmonella phage P22 has been recovered from matings between an Escherichia coli K-12 Hfr donor and an S. typhimurium recipient. The hybrid is an excellent host for achieving genetic recombination between lambda and P22. Two broad classes of hybrid phages were isolated. The lambda-P22 hybrid class, which has the protein coat of lambda, contains at least the c region of P22. The P22-lambda hybrid class has the protein coat of P22 and has inherited at least the c marker of lambda.
从大肠杆菌K-12 Hfr供体与鼠伤寒沙门氏菌受体的杂交中获得了一种对大肠杆菌噬菌体λ和沙门氏菌噬菌体P22敏感的异常鼠伤寒沙门氏菌杂种。该杂种是实现λ和P22之间基因重组的优良宿主。分离出了两大类杂种噬菌体。具有λ蛋白外壳的λ-P22杂种类至少含有P22的c区域。P22-λ杂种类具有P22的蛋白外壳,并至少继承了λ的c标记。
