Kaposi's Sarcoma Herpesvirus


My name is Kaposi's Sarcoma Herpesvirus, or HHV-8.

I'm part of the Herpesviridae family.

When I appear, people usually get a type of skin cancer called Karposi's sarcoma.
It gives you red-brown spots all over.

I'm rarely seen in people with good immune systems.
I'm very common in people with HIV or AIDS.

My name is Roseolovirus.
Sometimes I'm called Human Herpes Virus 6 (HHV-6) or '6th disease'.
I'm part of the Herpesviridae family.

I mostly infect babies and children.
First you get fever, but it doesn't last long.
When thats gone, I give you a rash called Exanthem subitum, or Roseola infantum.

I got my name because people thought my rashes were as red as roses.

Varicella-Zoster Virus

Hi there, I'm VZV.
My family is the Herpesviridae family.
Most people get me as children.
I'm much more serious when I first infect you as an adult.

I pick one or two nerves and only live in those.

My primary infection is called chicken pox.
You get itchy spots all over.
I also cause fever and rash.

My recurring infections are called shingles.
I give you big, red, painful blisters, but only on the parts of skin that connect to my special nerve.

My name is CMV.
Herpesviridae is my family.

My primary illness can look alot like my cousin EBV and sometimes we get confused for each other.
You may not even notice me at all.
I cause lots of problems in people with weak immune systems.

My primary illness in pregnant mothers stops babies from developing properly before they are born.

I have double stranded DNA.

My disease is called infectious mononucleosis, mono, and glandular fever.

Herpes Simplex Virus 1

My name is HSV-1.
I'm a double stranded DNA virus that's part of the Herpesviridae family.
I live in your nerves.
I have a primary infection, then recurrent infections.
My recurrent infection causes painful red blisters around your mouth.
These are called herpes labialis, or cold sores.
Bright sun can convince me to come out again, as well as stress, sickness and menstruation.

I can also cause a deadly encephalitis, which means I infect your brain.
If I get into your eye, I can give you herpetic keratitis and make you blind.

Herpes Simplex Virus 2

Hello, my name is HSV-2.
I'm a double stranded DNA virus (I'm made up of 2 DNA parts).
I'm part of the Herpesviridae family.
Us herpes viruses make our homes in your nerves.
Once we get in, we stick around for the rest of your life.

I cause genital herpes, a very common STI.
First you get a primary infection, with red blisters and an itching or burning as I play with your nerves.
You can also
feel headache or fever.

Later on, I travel back down to visit your skin, giving you more itching and blisters.
This can happen if you are stressed, sick, or when women are menstruating.

Calymmatobacterium granulomatis

Hi there.
I'm C. granulomatis.
I'm a Gram Negative rod shaped bacteria.
I'm found more often in developing countries, especially in tropical places.

I cause a STI with ulcers and sores that eat into you.
You can call it granuloma inguinale, but I like to call it donovanosis (easier to remember).
When I infect you, I get eaten up by one of your cells.
Together we make up 'donovan bodies' that can be seen under a microscope.

Caulobacter crescentus

My name is C. crescentus.
I'm Gram Negative bacteria.
I live in water or in soil, even if there's not much food about.
I'm very good at living in places with little food.

I make 2 daughters when I divide.

One is called a swarmer and has a special tail for moving around.
The other is called a stalked cell and has a long tube with sticky stuff at the end.
Both of these help me survive where other bacteria can't.
