You won't ever want to get any of these horrible and disgusting bacteria in your body here are the most shocking infections ever!

8. Streptococcus Pyogenes (pyah gen ease)
Like E.coli this dangerous bacteria can be found residing in a small percentage of human beings without causing harm. Around 700 million people are infected with the bacteria every year. Of those cases, around 650,00 are considered severe and invasive and come with a frightening mortality rate of 25%. Once you have an infection the bacteria has been known to cause a wide range of diseases from skin disorders and sore throat to scarlet fever. Luckily penicillin is usually an effective treatment for this bothersome bacteria.

7. Clostridium Difficile
As this bacterium overgrow they release toxins that attack the lining of the intestines, causing a condition called C.diff colitis. The bacteria develops spores that are resistant to high temperatures and aren’t affected by normal cleaning agents. The germ was estimated to cause nearly half a million infections in the United States in 2011 with 29,000 of those people dying within thirty days of diagnosis. Most mortalities are elderly and younger people.

6. Neisseria Meningitidis
This round shaped bacteria causes meningitis and other life threatening diseases. It’s the main cause of bacterial meningitis, which infects children and young adults, causing developmental impairment and death in 10% of cases. It can be spread through saliva and respiratory secretions during coughing or kissing and can only infect human beings.

5. Mycobacterium Tuberculosis
First discovered in 1882 by celebrated German physician Robert Koch this deadly bacterium is responsible for tuberculosis, which has been seen throughout history. An epidemic of tuberculosis known as the White Plague affected Europe for two hundred years starting in the 17th century. Europe’s poor sanitary conditions combined with its high population density made it the perfect breeding ground for the disease. Evidence of the infection has been seen in Egyptian mummies and human remains from the Neolithic era dating from 9,000 years ago.

4. Vibrio Vulnificus
This rod shaped, pathogenic bacteria is present in warm, shallow, coastal salt water in temperate climates throughout the world. When a wound is exposed to the sea water carrying this bacteria it becomes infected but it can also be contracted by eating raw or uncooked seafood that has been introduced to the bacteria as well. It can produce wound infections, causing potentially serious problems as it clearly did when it found its way into this Chinese man’s head. Just look as the damage it was able to do! The bacteria that causes cholera is related to this pathogen so watch out.

3. Bacillus Anthracis
This deadly bacterium is more commonly known as anthrax, an infection that became notorious in the United States thanks to an anthrax attack shortly after the September 11 attacks. Starting in September 18 2001 and spanning several weeks several letters containing anthrax spores were mailed to a number of news media offices and two Democratic U.S. Senators, killing five people and infecting an additional 17. The FBI called the ensuing investigation one of the largest and most complex in the history of law enforcement. Biologist Bruce E Ivins was found to have single-handedly prepared and mailed the deadly anthrax spores. He was initially involved in the investigation of his own attacks because he was regarded as a highly skilled microbiologist. Ivins committed suicide in 2008 after learning that criminal charges were likely to be filed against him.

2. Vibrio Cholerae
You may have guessed from it’s name that this bacteria causes the common disease cholera, which infects the small intestines through water and causes some very unpleasant symptoms like diarrhea and vomiting. The disease is most dangerous to poverty stricken areas where clean water isn’t readily available and is to blame for up to 142,000 deaths a year. The bacterium was first discovered by Italian anatomist Filippo Pacini in 1854. Most U.S. cases of cholera are from people who have acquired it during international travel.

1. Yersinia Pesti
Plague is the disease that this bacterium causes, making it the deadliest bacteria of all time. Everyone knows about the Black Plague that took place in Europe during the Middle Ages. It devastated the population and killed millions of people, wiping out a quarter of the total population at the time. Modern antibiotics have rendered the disease much more harmless in today’s world, but there are still a significant amount of cases in Africa and Asia. It is usually spread by a rodent flea or by handling animals infected with the plague.
