Resistant bacteria
Resistant bacteria
Strains evolved to survive antibiotics that once treated them
Why bacteria develop resistance quickly
Why bacteria develop resistance quickly
Reproduce rapidly, allowing frequent mutations
How mutations lead to antibiotic resistance
How mutations lead to antibiotic resistance
Mutations create new genes conferring antibiotic resistance
Selection pressure in bacterial resistance
Selection pressure in bacterial resistance
Antibiotics kill non-resistant; resistant bacteria survive
How resistance genes spread
How resistance genes spread
Resistant bacteria reproduce and pass genes to offspring
MRSA full name
MRSA full name
Methicillin-resistant Staphylococcus aureus
MRSA antibiotic resistance
MRSA antibiotic resistance
Resistant to multiple antibiotics
Where MRSA is particularly problematic

Hospitals (spreads easily as staff move between patients)
Why avoid antibiotics for viral infections
Why avoid antibiotics for viral infections
Antibiotics are ineffective against viruses
Why complete full antibiotic course
Why complete full antibiotic course
Eliminates all bacteria, reduces chance of resistant strains
