Q. How the bacterias are produced?

A1The Bacteria are a large group of unicellular microorganisms. Typically a few micrometres in length, bacteria have a wide range of shapes, ranging from spheres to rods and spirals. (The name comes from the Greek bakterion, meaning small staff.) Bacteria are ubiquitous in every habitat on Earth, growing in soil, acidic hot springs, radioactive waste,[2] water, and deep in the Earth's crust, as well as in organic matter and the live bodies of plants and animals. There are typically 40 million bacterial cells in a gram of soil and a million bacterial cells in a millilitre of fresh water; in all, there are approximately five nonillion (5×1030) bacteria on Earth,[3] forming much of the world's biomass.[4] Bacteria are vital in recycling nutrients, with many important steps in nutrient cycles depending on these organisms, such as the fixation of nitrogen from the atmosphere and putrefaction. Hope this helps.
A2for every cell in your body there are 10 bacteria that sits on you. in a nice eco balance... but if that balance is being interrupted - let's say you kill a group. there is place for the neighbors to grow, so they multiply. by doing so there are sometime mutations in their genes. this mutation can help the bacteria of harm it. so naturally the bacterias with the beneficial mutation will survive. this is why today there are bacterias that are resistant to all of our antibiotics.

Q. I am wondering why did he prescribe me a bacteria?

My doctor has prescribed some probiotic medicines for diarrhea recently and these medicines are actually bacteria…..I am wondering why did he prescribe me a bacteria?
ASome bacteria like Lactobacillius and Bifidobacterium are normally present in the guts of the humans and they are beneficial bacteria for humans. If not present or if they reduce in the guts then other harmful bacteria may invade your guts and will lead to other bowel problems, low immunity and ulcers. So these bacteria are friendly. Diarrhea would flush out these gut bacteria which have to be supplemented immediately by giving probiotics in some.

Q. Dog waste bacteria. How bad is it.Dose it ever die?

My husband has invented a Pet Waste-A-Way it liquefies the dog waste & it goes into the earth with in 8 seconds.We are worried about the environment & what it would do. We have gotten info back both ways. Some say it is there if you have dogs & some say it is bad & never dies.
A2Dogs existed before we made them pets, and in that time they would leave their waste on the ground, and it seems no ecological disaster happened. On the other hand, dog waste may harbor many parasites and bacteria, and these are the part of the past we generally would like to avoid...

I would make sure avoid spilling it close to water used by human either for drinking or swimming, or close to ground on which kids play.

Q. My left foot is swollen and painful. Can it be flesh eating bacteria?

I am a 24 years old lady and my left foot is swollen and painful. To be more specific it is not just swollen it's red, painful and hot. I just saw a TV show few days ago about "flesh eating bacteria". I know it sounds like I have hypochondria but I am very afraid.
A1To get a serious skin infection you need a port of entry for it. Think if you had any cosmetic therapy for your legs lately. If you can find a port of entry you can read here about cellulites - the name for swollen red and painful area of the skin.
A2Don't feel bad for caring for yourself. Yes, the risk that this situation is flesh eating bacteria (FEB) is small (maybe we saw the same show :)) but it's important to find out. I had cellulites (the thing that mimic FEB)once, and you sound to me like you have it too.
FEB is a more systemic illness with fever and with rapid enlargement of the swelling. Mark the red area on your foot. If it grows go to the ER for antibiotic therapy.

Q. I need to know anything there is to know about Diphtheria, where can I find information?

I have a paper that’s due to this Monday and I need to know where it comes from, what it is, and so on. If you could help me find a site that covers all i need to know that would be great.

Here's everything you could possibly need to know about it, including:

* Introduction
* Signs and symptoms
* Causes
* Risk factors
* When to seek medical advice
* Screening and diagnosis
* Complications
* Treatment
* Prevention
* Self-care
A2Diphtheria is an acute pharyngeal or cutaneous infection by Corynebacterium diphtheriae, some strains of which produce an exotoxin. Symptoms are either nonspecific skin infections or pseudomembranous pharyngitis followed by myocardial and neural tissue damage secondary to the exotoxin. Diagnosis is clinical and confirmed by culture. Treatment is with antitoxin and penicillin or erythromycin. Childhood vaccination should be routine.
Here are some sites about it:

Q. Can Cholera outbreak here in the U.S?

I looked for information about Cholera and couldn’t find much…
A1You can find any information in wikipedia. here is a link about Cholera :
and here is all the info about Cholera outbreaks in the world:
A2Well, as far ad I know- Cholera outbreaks usually happen in third world countries and that because of very bad hygiene. It’s a intestinal Bacteria that cause severe diarrhea. And I mean SEVERE diarrhea, so it spreads by sewage, people who does not wash hands after getting infected and cook for you. Those things get treated very fast here. So the chances are very unlikely. So I think anyway. Couldn’t find an article about Cholera in the U.S.A.

Q. Are superbugs contagious through the air?

Last week we visited my dad in the hospital, and we noticed that on the next room’s door there was a warning sign. After asking, we were told it was a denoting that the patient inside had a superbug (called klebsiella). On our way out we passed against this patient in the hallway – is it possible that I also carry this superbag? Is it dangerous?
A1Usually these bacteria are transmitted from person to person through direct contact, and less through the air. Moreover, these germs are dangerous in ill and debilitated patients, and not in normal healthy individuals.
A2No, you did not catch it. Klebsiella pneumoniae is a gram-negative rod-shaped bacteria. It can cause pneumonia although it more commonly implicated in hospital-acquired urinary tract and wound infections, particularly in people with weakened immune systems. It is an increasing problem on hospitals because of the evolution of antibiotic resistant strains. Since you are healthy and not hospitalized you cannot catch it. Only other patients can catch it.
