Gram Stain help :)

[janglypangly]

Hey guys I was wondering if any of you could help me with this question.

How could you differentiate between bacterial pneumonia and viral pneumonia using the Gram stain?

I looked everywhere online and can't find it, any help is appreciated. Thanks in advance!!

The most common causes of bacterial pneumonia are Streptococcus pneumoniae (http://en.wikipedia.org/wiki/Streptococcus_pneumoniae), Gram-negative bacteria (http://en.wikipedia.org/wiki/Gram-negative_bacteria) and "atypical" bacteria. The terms "Gram-positive" and "Gram-negative" refer to the bacteria's color (purple or red, respectively) when stained using a process called the Gram stain (http://en.wikipedia.org/wiki/Gram_stain). The term "atypical" is used because atypical bacteria commonly affect healthier people, cause generally less severe pneumonia, and respond to different antibiotics than other bacteria.
The types of Gram-positive bacteria that cause pneumonia can be found in the nose or mouth of many healthy people. Streptococcus pneumoniae (http://en.wikipedia.org/wiki/Streptococcus_pneumoniae), often called "pneumococcus", is the most common bacterial cause of pneumonia in all age groups except newborn infants. Another important Gram-positive cause of pneumonia is Staphylococcus aureus (http://en.wikipedia.org/wiki/Staphylococcus_aureus). Gram-negative bacteria cause pneumonia less frequently than gram-positive bacteria. Some of the gram-negative bacteria that cause pneumonia include Haemophilus influenzae (http://en.wikipedia.org/wiki/Haemophilus_influenzae), Klebsiella pneumoniae (http://en.wikipedia.org/wiki/Klebsiella_pneumoniae), Escherichia coli (http://en.wikipedia.org/wiki/Escherichia_coli), Pseudomonas aeruginosa (http://en.wikipedia.org/wiki/Pseudomonas) and Moraxella catarrhalis (http://en.wikipedia.org/wiki/Moraxella_catarrhalis). These bacteria often live in the stomach or intestines (http://en.wikipedia.org/wiki/Gastrointestinal_tract) and may enter the lungs if vomit is inhaled. "Atypical" bacteria which cause pneumonia include Chlamydophila pneumoniae (http://en.wikipedia.org/wiki/Chlamydophila_pneumoniae), Mycoplasma pneumoniae (http://en.wikipedia.org/wiki/Mycoplasma_pneumoniae), and Legionella pneumophila (http://en.wikipedia.org/wiki/Legionella_pneumophila).

I entered this thread half-anticipating a story about some disgusting stain left on the carpet after your grandma came over for a visit. Instead, I walked away mildly enlightened. Thank you.
