forgive me in advance for sounding like a crabby, conservative,
safety concious old man but...

If you have not got enough microbiology experience to know what
kinds of bugs to expect in a sputum from a pneumonia patient, you
have absolutely no business handeling such a sample.  Human
pathogens should be taken very seriously and only handled by people
with sufficient training to assure that they do not expose
themselves and others to inadvertant infection.

Now, to answer what you asked.  Streptococcus pneumoniae is a common
cause of bacterial pneumonias.  Klebsiella pneumoniae is less common
as are a number of others.  You can expect to find all sorts of
"normal flora " if the sample was not carefully collected, much 
less if it is a " clean" sputum
