Detailed Description

Gram-negative. Grow on nutrient or LB agar. E. coli HT-99 harbours a plasmid that includes a gene conferring resistance to the antibiotic chloramphenicol. Together with J53-R, it can be used to demonstrate bacterial conjugation [in this case, showing one way in which antibiotic resistance spreads].
