Preliminary report on the observation of a coronavirus in the intestine of the laboratory rabbit.

abstract：:Several restriction systems were detected in different strains of Streptomyces antibioticus by using actinophages as biological indicators. Adsorption of phages to the bacteria, together with the study of the efficiency of plating gave an initial indication of restriction in three strains. The alternation of efficienc...
