I don't know of any creationist or intelligent design proponent who disputes micro-evolution: the mutations of viruses and bacteria that has lead to bacterial resistance. Viral evolution is typically used as "proof" of the theory of evolution.
The rebuttal, of course, is that sure, micro-evolution occurs but that doesn't "prove" macro-evolution, e.g. that a bacteria will become an elephant given enough time and the right circumstances.
Also, I am not aware of anyone (other than Dini) who blames the over-medication of antibiotics on creationist physicians.
Bottom line: when Dini claimed The current crisis in antibiotic resistance is the result of such decisions --- the term such decisions was in reference to his own imaginings:
His whole statement tries to present his imaginings as facts and thus justification for why there should be no creationist physicians.
