Glowing Parasites

I'm always fascinated by how scientists can manipulate the green fluorescent protein from a jelly fish to learn about another creature.

Now, green fluorescent parasites are being used to infect rodents with malaria and the infection can be tracked throughout the life cycle of the parasites. Green fluorescent blood cells, green fluorescent mosquito eggs and green fluorescent sporozoites (cells that infect new hosts devoloping in the mosquito's salivary glands) are glowing life phases of the protozoa that causes malaria.
