i think is gram + It is gram positive, usually occurring in chains and pairs of gram positive cocci. It is also a beta hemolytic organism, meaning it will completely lyse RBC's in a zone around individual colonies. If you are using a Mannitol Salt agar medium, in this zone then it will be transparent.
S. mitis stains purple and therefore is a gram positive bacteria
Gram positive bacteria have a thick layer of peptidoglycan in their cell wall, which retains the crystal violet stain in the Gram staining process, causing them to appear purple under the microscope. Examples include Staphylococcus aureus and Streptococcus pyogenes.
Streptococcus pneumoniae is a gram-positive organism, which means it has a thick cell wall made of murein (or peptydoglycan as americans prefer to call it).
Strep A is a bacterial infection. As far as I know, onlyviruses are either enveloped or non-enveloped.
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.
Gram positive
Yes, gram negative streptococcus does exists. This is a type of bacteria that cannot retain a violet stain after the decolonization step of testing.
Streptococcus pyogenes is gram positive bacteria.
Never heard of that one. If you meant Streptococcus then yes, it is gram positive.

Frimbriae are structures related to Gram-negative bacteria. S. Pneumoniae, however, is Gram-positive. Therefore it does not have fimbriae.
Moryella indoligenes
Pneumococcal pneumonia is caused by the gram-positive bacteria Streptococcus pneumoniae.
Escherichia does not belong...bacteria of this Genus are Gram negative, the rest are Gram positive bacteria.
Streptococcus is a gram-positive bacteria which is spherical and grow in chains or pairs. They can cause pink eye and meningitis, among other things.
