SAN ANTONIO, Sept. 29, 2025 /PRNewswire/ — Infection rates from drug-resistant “nightmare bacteria” rose almost 70% from 2019 to 2023, according to a new study published by  Centers for Disease Control and Prevention researchers. These nightmare bacteria — Carbapenem-Resistant Enterobacteriaceae (CRE) — are a family of bacteria that have developed resistance to carbapenem antibiotics, a powerful class of drugs often used to treat infections that don’t respond to other antibiotics.
