Whoa, that is sad....this is what wiki has to say about her infection:

Pseudomonas aeruginosa is a commonly occurring bacterium that can cause diseases in both animals and humans. It is found throughout the world where there is soil and is found in both soil and water and in most man-made environments. It thrives in normal atmospheres but can also thrive where there is little oxygen, which enables it to colonise many natural and artificial environments. It uses a wide range of organic material for food and, in animals, this means that damaged tissues or people with reduced immunity can become infected with the organisms. The symptoms of such infection are generalised inflammation and sepsis. If such colonisations occur in critical body organs such as the lungs or the urinary tract and kidney, the results can be very damaging and potentially fatal[1]. Because it thrives on moist surfaces, it is also found on and in medical equipment including catheters and this can be the cause of cross infections in hospitals and clinics. It is also implicated in the condition "hot-tub rash" - a form of dermatitis associated with poor hygiene and low maintenance of hot tubs.
