  author={Sun Cheng-hu},
To study the relation between antibiotic resistance and plasmids for Bifidobacteria, experiments as below were conducted. With Staphylococcus aureus ATCC 25923 as the control bacterium, the antibiotic susceptibility patterns of 10 strains of adhesive Bifidobacteria were tested by the agar diffusion method. Twelve groups of antibiotics, thirty-eight kinds in total, are involved in the testing. Also the plasmids of the strains tested were extracted by using the alkaline lysis method. The results… CONTINUE READING
