Emerging bacterial threats are pathogens that pose new or increasing risks to public health. Examples include: - Clostridium difficile: Causes severe diarrhea and colitis, often linked to antibiotic use. - Carbapenem-resistant Enterobacteriaceae (CRE): Highly resistant bacteria that are difficult to treat. - Methicillin-resistant Staphylococcus aureus (MRSA): Resistant to many common antibiotics, leading to challenging infections.
