Pneumonia can result from a variety of causes, including infection with bacteria, viruses, fungi, or parasites.
Pneumocystis jirovecii causes pneumonia in people with AIDS. This pathogen was formerly known as Pneumocystic carinii.
The pathogen Streptococcus causes Strep throats.
A pathogen causes infectious disease. For instance, influenza virus is the pathogen that causes flu.

Pathogen
Double pneumonia does not identify which kind of pneumonia you have or which pathogen is the cause -- it is only identifying that you have it bilaterally, or in both lungs. Staph pneumonia identifies the actually pathogen causing the infection, Staphlococcus aureus, which is a very virulent pathogen. Staph pneumonia can be deadly if not treated properly. It may be helpful if you understand that there are many different forms of pneumonia, and that being diagnosed with "pneumonia" itself isn't a death sentence by any means -- it simply means you have inflammation and fluid in the lungs. This inflammation and fluid can be caused by a virus, bacteria, fungus or parasite, and sometimes is just caused by damage to lung tissue without any infectious origin at all. In most cases, pneumonia will clear up with antibiotic therapy, and the people with the highest risk of dying from the disease are very young children, elderly, and people with compromised immune systems.
I assume you mean bacterial pneumonia, from there it is dependent on what type of bacteria is causing the pneumonia. For example Streptococcus pneumoniae is gram positive, but Klebsiella pneumoniae gram negative.On the whole though, bacterial pneumonia is more typically caused by gram positive bacteria.
possibly it causes pneumonia, so you could say it causes pneumonia. pneumococcus
No. Certain bacteria causes pneumonia.
