Halloween has come and gone this year, but America’s interest in Zombies still lives on. Zombies are all the craze now on TV and in movies. You might be familiar with The Walking Dead, however there were many that came before this hit TV series including Shawn of the Dead, World War Z, 28 Days Later, Resident Evil, and 28 Weeks Later among others. Zombies really exist in nature. Usually “zombies” in nature are the result of a parasitic relationship. This type of relationship is when one member of the pairing benefits while the other is harmed.There are an array of parasites that include viruses, fungi, protozoa, wasps, and tapeworms. Parasites have different goals when invading a host.
