Final answer:
True, antibiotic resistance is a serious global health threat, with every class of antibiotics affected by resistant strains of bacteria.
Step-by-step explanation:
True. Every antibiotic drug class has resistant organisms that influence prescribing decisions. This resistance arises due to various factors, including the excessive use of antibiotics leading to the natural selection of resistant bacteria, the misuse and overuse of these medications, and the subsequent adaptation of infectious organisms to the drugs. Bacterial antibiotic resistance is a serious global health threat as it causes an increasing number of infections to become difficult to treat. Antibiotic resistance occurs when bacteria evolve and change, reducing the effectiveness of drugs designed to cure or prevent infections. Conditions such as MRSA and multidrug-resistant tuberculosis (MDR-TB) exemplify the challenges of treating infections caused by these resistant strains.
