Question
Why was the presence of a carbapenem resistant E. coli strain of even greater concern as a health-care threat?
Escherichia coli is extremely mobile and is able to secondarily “contaminate” other body orifices
Escherichia coli is a very common part of the flora. An antibiotic resist E. coli strain could thus become a notable source of infection, even among the healthy
Escherichia coli can produce endospores, so it could easily contaminate hospital equipment
Escherichia coli is much smaller and can replicate faster, thus is a concern because its population can grow quickly

Explanation / Answer
The answer will be Escherichia coli is a very common part of the flora. An antibiotic resist E. coli strain could thus become a notable source of infection, even among the healthy (Option 2).
Explanation: E. coli is a non-spore forming bacteria. So, we can ignore option 3. Though other options are correct in some way but option 2 will be correct answer in the current question scenario. Carbapenem is used as the last resort for treatment of the multi-drug resistant infections in humans. But increased use of carbapenem showing carbapenem-resistant bacteria in various strain. If carbapenem is also resistant to bacteria then it reduce the therapeutic options. Moreover, a carbapenem resistant E. coli strain can cross contaminate other bacteria. E. coli is very common in our gut flora & removed through feces. Thus a carbapenem resistant E. coli strain can easily cross-contaminate other E. coli & bacterial strain & become a notable source of infection. Thus the correct answer will be option 2.
