Which bacteria are most deadly?
There is a relatvely short list of "deadly" bacteria if you really just want to know which bacteria are the most feared. They would include Bacillus anthracis, Yersinia pestis, Francisella tularensis, Brucella species, Burkholderia mallei, Burkholderia pseudomallei, Mycobacterium tuberculosis. There is far more to this issue than deadly though. As others have stated, the immune status of the host plays an important role but there are certain bacteria that are highly infectious and would infect nearly every person who was exposed but would most likely not kill the host. There are others that do not generally infect many folks but pose extreme danger for anyone who gets infected. Terrorists break the rules because an idiot is actually creating a scenerio that causes infections with highly lethal bacteria.





Most of the bacteria mentioned by others are much more common and perhaps that makes them dangerous but many of them can be found in healthy people without any obvious symptoms. Unfortunately, nearly harmless bacteria are potentially dangerous for a compromised person. So quit smoking now, wash your hands after using the bathroom, keep your figers away from your eyes, ears, nose, mouth and any other openings, eat a balanced diet, don't over-eat, get some exercise, know your sexual partners and their history very well or don't have sex with them. It is much safer to prevent infections than to try to treat them.





Bacteria are found pretty much throughout your ailimentary canal and are perfectly normal there. They are also on your entire outer body and are again normal there. They are in the air you breathe and the water you drink. Unfortunately, your favorite eatery may also have some bad ones in your food. Beyond this, go to college and major in microbiology.

Botulism isnt a bacteria - it is an oxide of tin metal!
Reply:i dont much about bacteria.


but i do know about botulism.


botulism is a food poisoning and can be found mostly in canned goods, you can tell if the can is dented or under pressure, in or out.


it also grows on many other foods, but you really can't tell.


just a small bite of it, and, and my science teacher says,


"it will kill you dead."


very dangerous..


yes. im a hypochrondriac, thats why i know this :)
Reply:"The most common fatal bacterial diseases are respiratory infections, with tuberculosis alone killing about 2 million people a year, mostly in sub-Saharan Africa."





The most deadly is probably Bacillus anthracis with causes Anthrax.
Reply:staph and MRSA are the worst... and they are contracted when u have an cut or wound of some sort and dont keep it clean... MRSA is really bad... its fairly new and they're having a hard time treating it
Reply:You're going to have to think about exactly what you mean by "deadly." WildRockMan is correct about M. tuberculosis. Its prevalence, especially in areas with limited ability to treat those people, makes it a major killer. On the other hand, Yersinia pestis and Bacillus anthracis aren't seen every day, but pulmonary infections with either tend to have very high mortality. In developed western societies, common organisms like E. coli, Strep. pneumoniae, and Staph. aureus cause a lot of minor disease, are generally not that dangerous, but are at the top of the list of infectious diseases causing death again in large part because of their prevalence.
Reply:I would say staphylococcus aureus, because it can cause a septic shock and kill the person.





Here more explanation.





Staphylococcus aureus can cause a range of illnesses from minor skin infections, such as pimples, impetigo (may also be caused by Streptococcus pyogenes), boils, cellulitis folliculitis, furuncles, carbuncles, scalded skin syndrome and abscesses, to life-threatening diseases, such as pneumonia, meningitis, osteomyelitis endocarditis, Toxic shock syndrome (TSS), and septicemia. Its incidence is from skin, soft tissue, respiratory, bone, joint, endovascular to wound infections. It is still one of the four most common causes of nosocomial infections, often causing postsurgical wound infections.





IT CAN BE FOUND.





S. aureus may occur as a commensal on human skin (particularly the scalp, armpits, penis and vagina); it also occurs in the nose (in about 25% of the population and throat and less commonly, may be found in the colon and in urine.
Reply:This is highly a function of the host's immune status, so there's really no simple answer.
Reply:As somebody already mentioned, MRSA is a pretty bad bacterial infection. MRSA stands for Methicillin-Resistant Staphylococcus Aureus. What that all means is that the Staphylococcus aureus is resistant to the antibiotic, methicillin, which is used to heal the infection. For a MRSA infection, the only thing we have left for the infection is vancomycin. Vancomycin is pretty much the last resort. However, now there are even some Staphylococcus aureus that are resistant to vancomycin. These are very deadly bacteria because even vancomycin doesn't work for it. Pretty much, we have no antibiotics for it. To prevent these superbugs (bacteria resistant to many antibiotics) from arising, we should be very careful with using antibiotics. We want to avoid misuse of antibiotics. Some ways we can do that is to take antibiotics as the doctor tells us to. Avoid antibacterial soaps and handwashes because soap itself is antibacterial....we don't need to add antibiotics to the soap to make it antibacterial. All that does is give an opportunity to bacteria to develop resistance.
Reply:There is no way to say which is deadliest, because that depends on what you mean by your question, where you are in the world, etc. I will give you some interesting examples.





The deadliest bacteria are usually spread via respiratory droplets, but one bacteria, which causes the most deaths, is found in contaminated water. Vibrio cholera is the bacteria responsible for cholera. It secretes a toxin which causes profuse diarrhea (up to 10 gallons/day), which causes severe dehydration and death to those in developing countries.





Mycobacterium tuberculosis is a worldwide problem. In 2005, 8.8 million people fell ill and 1.6 million people died. This is a respiratory disease that can spread to virtually any part of your body and mimic almost any disease.





Yersinia pestis is the bacteria responsible for the plague, which wiped out nearly a third of the European population at one time. It is a bacteria that was associated with the ticks that infect rats. When infecting humans, infection of the lungs is the deadliest and the transmissible form of the disease. Today, antibiotics offer a 90% survival rate, but oubreaks have recently occurred in the desert southwest.
