No, there are different bacteria.

yes there are antibiotics that can treat esbl infections, carbapenem, ertapenem, aminoglycosides are some of the class of drugs that are used.

The KPC gene encodes for an enzyme known as Klebsiella pneumoniae carbapenemase, which is a type of beta-lactamase enzyme that confers resistance to carbapenem antibiotics in Gram-negative bacteria, particularly Klebsiella pneumoniae. This gene is associated with the spread of carbapenem-resistant strains of bacteria, posing a significant threat to public health.

Absolutely NOT. The reason super bugs like MSRA and the new carbapenem-resistant Enterobacteriaceae or CRE infection is so terrible is because people OVER-USE antibiotics! Never take anyone else's medicines. Always finish the antibiotic given to you for an infection. Never take antibiotics for a cold, flu or other viral infection. Never take antibiotics as "prevention"-- UNLESS a doctor instructs you to do so.

If you are talking about the culinary confection known as marzipan, that's a big "No!"

If you are talking about a brand of Meropenem (a carbapenem antibiotic) that seems to have a trade name of marzipan, any injections should be done by a doctor or under their direction.
