C diff does not cause any problems in healthy people.

However, some antibiotics that are used to treat other health conditions can interfere with the balance of 'good' bacteria in the gut.

When this happens, C diff bacteria can cause symptoms such as diarrhoea and fever. As C diff infections are usually caused by antibiotics, most cases usually happen in a healthcare environment.

Most people with a C diff infection make a full recovery.

However, in very rare cases the infection can be fatal.

MRSA stands for Methicillin Resistant Staphylococcus Aureus.

Staphylococcus aureus is a commonly occurring bacterium.

MRSA is a variant of Staphylococcus Aureus.

Many years ago, at the onset of antibiotic use, infections caused by Staphylococcus Aureus were easily treatable.

However, over the years, these bacteria have developed resistance to antibiotics.

Usually, MRSA simply lodges on the skin without creating any symptoms.
