Which trial do we need? Ampicillin versus ampicillin plus ceftriaxone for E. faecalis endocarditis: is it time to start re-considering monotherapy?
Reviewing the evidence behind some established practices in infectious diseases is
both a professional responsibility and an ethical duty of the scientific community.

Pneumonia patient on ampicillin-sulbactam
Blood grows Strep pneumo, sensitivity pending
Patient is improving
Sulbactam adds *nothing* to ampicillin for S. pneumo (resistance not mediated by beta-lactamase)
So you can immediately narrow to ampicillin #IDsky #EMIMCC

Another plasmid I am excited about offering is this fully open source Taq polymerase expression circuit. Inducible via lactose or IPTG. Ampicillin selected. Born free. You can make your own polymerase and purification is as easy as boiling water and centrifuging. Coming soon!

"Okay, but these other guys weren't even exposed to the drug. How are they resistant?"
"Gasp!"
"What?"
"They're sending the data to each other with genetic material fragments!"

Using ampicillin as a selectable marker? You can skip the post-transformation outgrowth! Why? Because Amp targets cell wall synthesis, not protein synthesis, so the bacteria isn’t impeded from making the protein it needs to combat it! youtu.be/XZn8QG6dzgc

Yay, the ampicillin version of my transposase vector is finished! Got seq results this morning and it looks good. Now all I'm waiting for is the sacB gene fragment to arrive and I can greatly accelerate my transposase-mediated chromosomal integration experiments. Stable abx-free rainbow bugs soooon!

YES!!! No growth on ampicillin but LB growth still glows. Integraaaationnnnn 🥳
Okay so new protocol:
1. Clone GOI into Himar1 vector
2. Transform into your target bug
3. Streak once on LB Amp 37°C
4. Streak twice on LB 45°C
5. Test for susceptibility to Amp.
6. Sequence
Yay!
