I was recently diagnosed with bacterial Pneumonia, in addition I had a severe bladder infection last month that went untreated for 2weeks.  In researching the cause of my Pneumonia online, I came across a specific bacteria found in kidney infections that can migrate to the lungs in severe cases, causing Pneumonia. I cant seem to find the article again where I found this information, and would really like to know the name of this bacteria, I have a feeling my bladder infection that went untreated for 2 weeks my have been the root cause of my pneumonia.  Please help.
Many types of bacteria can cause both pneumonia and a bladder infection. It is very possible that some bacteria from your bladder got out into your blood and were carried to your lungs to cause the pneumonia. You might also have gotten 2 different types of bacteria in each area just coincidentally. Some of the bacteria that can cause both Otis and pneumonia include E. coli, Klebsiella, Pseudocodes, Enterococcus, Staphylococcus and more. In fact, most common bacteria have the potential to cause infection in both areas. So I can say yes, its very possible your untreated UTI was the cause of your pneumonia, but only cultures from both areas could prove whether it was the same bacteria. Hope this helps.
