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.

Staphylococcus saprophyticus

My name is S. saprophyticus.
I'm a Gram Positive cocci like my cousin S. aureus.
But I'm a little different to him, I'm called a "coagulase negative" staph, which means I react differently then him in a special test.

Staphylococcus aureus

Hello there!
You can call me S. aureus.
I am a Gram Positive cocci (round) bacteria.

HACEK bacteria

We are the HACEK bacteria.
We are a special group of Gram Negative rods.
The word "HACEK" is an acronym of our names.
We are Haemophilus aphrophilus (and Haemophilus paraphrophilus), Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens and Kingella kingae.

We live in the mouth, throat and urogenital tract, but most of the time we don't cause many diseases.
When we do cause diseases, we love to cause endocarditis in people's hearts.
Endocarditis is inflammation of your heart valves.
