title: Development of Escherichia coli virus T1: escape from host restriction.
abstract: The bacterial virus T1 grows interchangeably on different Escherichia coli strains (C, B, and K). This implies that T1 has an efficient mechanism to overcome the host restriction barrier. The DNA of T1 was found to be methylated independently of the hosts. The percentage of N6-methyladenine varied from 1.6 to 1.8, and the 5-methylcytosine content varied from 0.1 to 0.4%. In contrast, the range in percentage of N6-methyladenine and 5-methylcytosine found in the hosts was 0.7 to 2.4 and 0.0 to 1.1, respectively.
