Final answer:
Antibiotic-resistant strains such as MRSA and Multidrug-Resistant Mycobacterium tuberculosis are increasing due to misuse and overuse of antibiotics, representing a significant challenge to modern medicine.
Step-by-step explanation:
Compliance problems with antibiotic use are leading to a large increase in antibiotic-resistant strains of various bacteria. As highlighted by current medical findings, one of the most notorious of these is methicillin-resistant Staphylococcus aureus (MRSA), a bacterium that is resistant to a multitude of antibiotics. Multidrug-Resistant Mycobacterium tuberculosis, which includes MDR-TB and XDR-TB, is another critical concern, thriving due to improper antibiotic treatment procedures. This increasing resistance poses a severe challenge to treating infections, as it decreases the effectiveness of standard antibiotics, leading to higher rates of morbidity and mortality.
