community the risk is revealed in new research but trinity college's dental school and an optional mrsa reference not to over ten years the scientists has a large community infections but strains of the potentially dangerous often antibiotic resistant bacteria. they discovered a forty four fold increase in the number of infections and six fold rise in him and strains resistant to multiple topics. most were associated with skin infections but some are like sixty cases of serious life threatening conditions on like things that can cause infections in the longer more. isn't it and stick to these donuts for five months. study about twenty cents of the individuals within range was this year also funds increased diversity and the strains of mrsa in the community into the stocks to grey shirt into enough trouble with people coming back into the country inadvertently bringing the books with them. watch this. most of it strains circulating in arms. someone made the comfort on that time may spread rapidly but we didn't win it so we too need to continue to watch this jesse says this is targeted to

doctors carry these bugs, mrsa from patient to patient. the tip of the stethoscope has 89 germs. the bacterias. >> it's a whole neighborhood. >> the tip of the fingers have about 467 of them. the thumb was about 37. >> and your tie? >> that's a good one. this is another one. the doctor leaned over to look at the stethoscope and the tie gets contaminated and this goes from patient to patient. that's one of the reason yes paid w pediatricians wear a bow tie. >> the lab coats are loaded with bacteria. >> this is another horror story. another study was done in indiana. they find out that the doctors are not washing their hands. only 13% and 5% do it correctly. you want to bring the fingers and really wash them at the palm of your hands and go for at least 30 seconds and wash them and dry that. that becomes a hand. >> this is a big problem. >> hand sanitizers are on the outside of every room now. most hospitals have them outside of the door. please use them whether you are a doctor or a patient. >> i actually thought when the doctor took the stethoscope to warm it up, but no more. wow

mrsa's findings were immediately forwarded to the emergency rescue center in perth yesterday. emphasized that we cannot tell wlur the potential objects are from mh-370. nevertheless, this is another new lead that will help direct the search operation. we have now have four operate satellite leads from australia, from china and france showing possible debris. it's now imperative that we link the debris to mh-370. this will allow us to locate the search more for the plane. authorities are leading the search in the southern indian ocean based out of perth. malaysia continues to play a coordinating role. all countries involved are displaying unprecedented levels of cooperation. that has not changed. australia has divided the search efforts into two sectors. the east and the west. today, the weather has improved, and 12 planes will travel to the search area, six in the e sector, and six in the west. in the east sector, searching will be conducted by one australian p-3 orion and 3 aircraft. one orion. in the western sections, searches will be conducted by u.s. p-8 pos sidian. weren'

the study did also show mrsa on some of these stethoscopes. that is the super bug. the one thing is it doesn't show which path logical bacteria are there and can they actually cause infection. i would like to see the study which is rammed into hospitaling right now. is it passing from doctor's lab coats to stethoscopes to patients. put a little alcohol on your stethoscope. >> what if i go to the doctor and say hi, doc, would you wash that? will he just make a joke about it. >> you're not insulting him. but it's perfectly your right to say please wash your hands or stethosco stethoscope. fortunately i don't carry a stethoscope anymore. but thislele study th study tha mayo klinic is very critical. >> 89 different little bacterias? >> the tip of the fingers had about 467 of them. the thumb was like 37. >> and your tie? >> that's a good one. this is another one. so if the doctor actually leans over to hook at the stethoscope, the tie that gets contaminated and this goes on from patient to patience. that's one of the reasons why pediatricians wear a bow tie. >> lab coats

we got all types of mrsa here. we got staph infections. we tell you a third time, we put your stuff out of the gate and you got to go. you don't step on nobody's toes. you're good. >> though nunez was only arrested on drug charges he admits selling an unregistered handgun to stark who completed his first night here. stark was arrested because the gun he purchased was used by his friend robert leonardes to shoot at police officers. >> yesterday i was just emotionally distraught and the fear of just not what is going to happen to me and who was going to be there for me was very hard. my mind was all over the place but i've gotten a lot calmer and my head's in the right place. >> because of their connections to the high-profile case, stark and nunez were immediately placed in separate maximum security housing units. most other new inmates were assigned to a temporary unit until the jail's classification unit can determine the appropriate housing unit. deanna collins has been in the female pre-classification unit for two weeks now. >> we have

talk about mrsa, for instance, all those things very commonplace. very little room to maneuver.why 23,000 people die every year and you have so many infections. the fight is to find new chemicals, new bathways to attack bacteria. now scientists have discovered at least something they can sort of put a flag on, move forward and mark. so for us i think it's very exciting. >> that's good. because people worry, right, greg? you go into a hospital with one thing and then you can pick up an infection. if there isn't an apartment by theic to control it, maybe these pain killers hold some truth. but with every medicine i'm sure there's a little poison. >> is there? we hear that. >> sure. i mean, everything -- you don't want to take a lot of medication. and everything has a side effect. they could harm you. the big question is when you have now -- if you take any of the nonsteroidals you're familiar with, ibuprofen or alleve, we sort of knocking off some bacteria in our bodies that we shouldn't. that's going to be the point of analysis further on. but exciting point is that the chemistry

that can cause cuticle infections, finger herpes, staph, mrsa and more. but to find out the dirty truth for ourselves, 20/20 used hidden cameras, in glasses, purses and even a water bottle. and documented any germ spreading students, like this. check out this woman as she takes a cotton ball with nail polish remover, uses it on her own nails and then the same one right on us. >> that's how we can impart bacteria on people. >> watch as she grabs this old nail buffer, what looks like white chaling is probably someone else's dead skin. without hesitating, she uses it on us. a major no-no. those devices are one-time use only according to state regulations. is it really so bad that everything must be cleaned and disinfected? we swabbed and swabbed and swabbed all over the salon, and sent it to the lab. in one foot bath, they found 28 million bacteria from feces. and on a pedicure towel, staph. >> if you have a break in the skin that is one way the staph can get into there, by using the towel. >> worst of all, we found salons using illegal instruments. is that
