enteric bacteria

anonymous asked:

When viruses and bacteria first enter the body through the nose, they encounter the hairs lining the nostrils. These hairs trap nearly every particle that's inhaled, and they contain mucus that dissolves bacteria. A virus may survive, however, if it becomes detached from a nose hair and is sucked deeper into the nose. From the back of the nose, the virus can either go to the stomach, where it will be destroyed, or make its way to the throat, beginning the process of giving the person the flu.


Why Does No One Talk About It?: UTI’s And Other Infections

I’ve noticed that no one ever talks about UTI’s. No one talks about them even though most women suffer from them at least once in their life time. It’s same the with Yeast Infections.

I almost lost my left kidney to an asymptomatic bladder infection that moved to my kidneys. I found out only then, when I was lying in the hospital in pain and the doctors telling me that if I didn’t increase kidney function and stop peeing blood that I might have to get my kidney removed, that almost all women suffer from them! Whether it start when they become sexually active, when they become pregnant or just as a common problem! My mother has suffered from them since her early teens!

A UTI (Urinary Tract infection) occurs when bacteria enters the urethra and irritates the sterile area that is the urethra and bladder (Pee is sterile, who knew?) Now, the bodies way of trying to get rid of said bacteria is by creating the urge to pee as often as possible, burning sensation when urinating and an empty bladder.

There are ways to prevent it though.

Bladder infections are most likely to occur after sex, when PH Balance of the vagina is changed, during or after pregnancy when bladder control becomes an issue.

- Drink lots of water!

- Also drink lots of acidic fruit juices such as cranberry, pomegranate and orange. These help cleanse the bladder.

- Always urinate after sex to aid in the expulsion of any harmful bacteria from the area.

- Cleanse, but do not over cleanse. We always hear about these soaps or other ways of helping maintain PH balance. But did you know that the vagina is completely self sufficient and will ALWAYS return itself to proper PH whether it be after sex, pregnancy or menstruation.So, keep clean, but do not fall into the fear of over cleansing. (Unless told by a physician that you do have a problem)

- GO TO THE DOCTORS! I can’t stress that enough. If you have frequent bladder infections, go the doctors and get a script. Take it from me, you do not want to be in the hospital unable to breathe and vomiting from the pain while you pee blood while contemplating the need for surgery on a vital organ.

I know it was a random thing to write, but it was on my mind after talking to a friend about it, lol. Hope it helps someone out there!!!

Candy and Your Microbiome

Sugar doesn’t cause cavities—bacteria do! Sugar alone has no effect on teeth. But eating sugar does cause cavities. Here’s how it works:

What happens when bacteria on my teeth consume sugar from my food?

Some bacteria release acid that dissolves minerals in your teeth. Every sugary drink or snack releases a new round of acid.

What happens if I don’t brush my teeth and plaque (a sticky biofilm made of billions of bacteria) forms on my gumline?

Plaque blocks saliva, allowing acid to dissolve teeth nonstop.

What happens if acid is allowed to remain on my teeth too long?

Acid can dissolve holes in teeth called cavities. Bacteria can enter the tooth and infect nerves in the roots, causing toothaches.

TSI (Triple Sugar Iron) slants, used to differentiate and characterize mostly Enteric bacteria and facultative anaerobes. both aerobic and anaerobic growth can be studied because the slant is stabbed, and the the inoculating needle is then “wiggled” up the slant as it is pulled out. this will facilitate the growth of the bacteria, if it has the ability to grow in an aerobic setting. otherwise, no color change is observed in the slant region, while change in color is seen in the “butt” part of the slant. seen here on the left, is a bacterium that has the ability to ferment all three sugars present in the media as well as produce gas (the large empty gap at the bottom leading it to look like a “floating island”) along with production of an acid, altering the color of the slant from red to yellow. this is a typical result for a facultative anaerobe and an enteric bacteria such as Eschericia coli. the middle slant shows an alkaline slant and an acidic butt while the tube on the right illustrates the production of H2S (hydrogen sulfide).

After 24 hours of growth, this image depicts four different agar media culture plates that had been inoculated with Shigella sp., Escherichia sp., and Proteus sp. bacteria, (clockwise: MacConkey, Shigella-Salmonella, Bismuth Sulfite, and Brilliant Green agars).

Differences in the constituents, which compose the various agar media, are used as determinants as to which bacteria are fostered on each culture plate. Thriving culture colonies on one type of medium may not thrive on another type of medium based on the agars’ ingredients, which a given bacterium will require to maintain life.
