Yоu plаte оut а liquid culture оf E. coli on TSA contаining the antibiotic streptomycin, incubate for 24 hours, and observe a single colony. From this you obtain a pure culture of streptomycin resistant E. coli, which you propagate on TSA with streptomycin in the following weeks.

Months later, you discover your E. coli strain is no longer resistant to streptomycin. Please explain this result fully in paragraph form, a minimum of 4-5 sentences. Why was your original colony resistant to streptomycin? Why, months later, did you end up with a culture that was not resistant to the antibiotic?
