Hello, I'm S. pneumoniae.
I'm a Gram Positive coccus.
Sometimes I'm known as the 'pneumococcus'.
I'm found in some people's airways.

Streptococcus sanguis
Hi, I'm S. sanguis.
I am a Gram Positive coccus, but I am not a B haemolytic strep.
I am an A haemolytic strep, which means that when I'm grown on a blood agar plate, I end up green.
I am also known as a Viridian strep because of the green colour I make.

Streptococcus bovis
Hi, I'm S. bovis.
I'm a Gram Positive coccus and in the D Lancefield group.
However, I only look like a B heamolytic strep in a test made from rabbit blood.
On another test, made from sheep blood, I am an A heamolytic strep.
I cause endocarditis and get into the blood to cause bacteraemia.
I am also found in alot of places where colon cancer is found.
So if you have me, you should always check for colon cancer.

HACEK bacteria
Hello.
We are the HACEK bacteria.
We are a special group of Gram Negative rods.
