Can You Get A Bacterial Infection More Than Once

What Happens When You Dont Brush Your Teeth

No one likes going to the dentist, but youshould all go every year. Because really, do you want to risk an infection in the biggesthole in your headé! Hey guys, Amy talking the joys of oral hygienewith you on DNews today! As many as 700 types of bacteria can livein our mouths, though most people only host between 34 and 72 varieties. Some of thesebacteria are innocuous, others known as probiotics actually help us digest food. There are evenbacterial strains that protect our teeth and gums. But there are some bad bacteria livingin your mouth as well. One is called streptococcus mutans. This bacteriafeeds on the sugars and starches you eat,

producing enameleroding acids as a byproduct,which can lead to tooth decay. Another bad bacteria is porphyromonas gingivalis, whichis linked to periodontitis, a serious and progressive disease that affects the softtissue and the alveolar bone that support the teeth causing tooth pain and in some casestooth loss. For most of us, our main dental issue willbe plaque, the film that builds up on your teeth and contains the bacteria that producesenameldestroying acids. Regular cleanings get rid of plaque, but if you don't cleanthe plaque from your teeth it hardens into tartar, which can get below your gums, causinginflammation and infection. That can open

a pathway into your bloodstream. Once thatbacteria is in your blood, it can get anywhere. The first place that bacteriafilled bloodcould go is your heart where there is some evidence that it can lead to atherosclerosis,or a hardening of the arteries caused by plaque, though this is a different kind of plaquethan you'd find on your teeth. The plaque in your arteries is made of cholesterol, fattysubstances, cellular waste products, calcium and a clotting agent called fibrin. It buildsup and thickens the walls of the arteries, constricting blood flow and increasing riskof a heart attack. Clogged or blocked arteries can also restrict blood flow to the brain,increasing risk of stroke.

A recent single study in Osaka, Japan,found that a quarter of stroke victims had a bacteria called cnmpositive S. mutans intheir saliva. The researchers acknowledged that it's a rare bacteria only 10 percentof people have, but it's still enough to reinforce the link between the oral bacteriumand stroke. And mouth bacteria can even follow a pathto your brain, increasing risk of dementia. A 2013 study from the University of CentralLancashire found a correlation between the bacteria commonly associated with gingivitisand an immune response that may kill neurons. This could ultimately change the brain ina way consistent with Alzheimer's disease.

And, if that weren't bad enough, letting bacteriaform colonies in your mouth can also lead to lung infections, but not through the bloodstream…Instead you literally breathe oral microbes into your lungs, where it can infect and spread. And your oral health doesn't just impactyour body health, it can be a good indicator of your overall health. For example: gum diseasecan be a sign of diabetes, painful mucosal lesions are more common in people who areHIV positive, and tooth weakness or loss can be a sign of osteoporosis. So it should be said that this is a huge “moreresearch is needed� topic since most studies

have small sample sizes and need followupwork. And experts somewhat begrudgingly admit that we just don't know yet whether treatinggum disease can reduce the risk of heart attack, stroke, or dementia. But, really, do you needmore motivation for keeping up with dental visits than maintaining good teeth for chewingéFloss! Brush! And above all: go to the dentist!

4 Nastiest Parasites in the World

These are the four nastiest parasites in theworld. Warning: this content may be disturbing to most people. Number 4: The Guinea WormThe guinea worm is a nematode that causes disease most commonly referred to as “guineaworm disease.� This disease is caused by people drinking water that has been contaminatedby guinea worms and water fleas. When one is infected with a guinea worm, they willfirst not feel any symptoms. Then after a year or so, they'll begin feeling a burningsensation on their skin. This is the worm developing blisters underneath its host'sskin. They will also experience nausea, vomiting,

fevers, rashes, and dizziness. If the wormis not removed, it will likely die inside of the human, causing paralysis of the spinalcord or arthritis in the joints. Guinea worms often grow longer than 2 feetlong. Although the worm can be removed, they do form ulcers in the process that can becomeinfected. The resulting pain has the potential of lasting up to a few months. There are novaccines for guinea worms, but steps to prevent the disease from getting worse can and shouldbe taken. Submerging the infected area into water forcesthe worm to discharge its larva, thus lowering the risk of infection. The worm is then removedby wrapping it around a stick and slowly pulling

it out, a process that is said to feel likethe infected area is literally on fire. In the most extreme of cases, this removal processcan take up to several weeks. Number 3: Filarial WormsFilarial worms are parasites that are passed on to humans through mosquitoes. Similar toguinea worms, filarial worms reside in the body for roughly a year after infecting someone.They then move into the lymphatic system and clog up excess fluids in the region wherethe worms have settled. This causes the fluid to accumulate and therefore enlarge the areahosting the worms. This disease is known as Elephantiasis Tropica.

In addition to the lymphatic build up, filarialworms cause skin rashes and arthritis. They even have the capacity to cause river blindness,which is one of the leading causes of blindness in the world. Different types of medicine and surgery havebeen used to treat those infected with filarial worms. The World Health Organization claimsthey are on track towards eliminating the disease through a process known as geotargeting. Number 2: PinwormsPinworms are nematodes responsible for one of the most common parasitic infections inthe world. This infection is known as enterobiasis.

The pinworms themselves are very small, reachingup to only 13 mm in length. However, once they infect a host they cause intense itchingand sometimes pain near the anus. As a result, bacterial infections are often associatedwith pinworms. Other possible symptoms include irritability, insomnia, appetite and weightloss, urinary tract infections, and uncontrolled urination. Those who have ingested pinworm eggs oftendo so from contaminated food, water, or from other people. But medicine for these infectionsis considered to be very effective. Additionally for those infected, there still remains ahigh possibility of reinfection even after

they've already been treated. This is dueto the fact that drugs kill the pinworms but not the eggs themselves. Therefore, it isoften recommended that patients seek continued treatment for two to three weeks after theirinitial treatment. Number 1: New World ScrewwormThe new world screwworm is a parasite that is known for feeding on live tissue. They'reindigenous to Central and South America. The new world screwworm is known to infect thewounds of large animals such as cattle, horses, and sheep. There have been, however, manyinstances where they've affected humans as well.
