Does furadantin (nitrofurantoin) work for uti's or is there antibiotic resistance now?

Does furadantin (nitrofurantoin) work for uti's or is there antibiotic resistance now?

Yes, yes: Furantoin still works for many utis but there is also antibiotic resistance so you may need another antibiotic. ...Read more

Tolerance (Definition)

When one takes a drug, such as heroin or alcohol, repeatedly, 'tolerance' develops because more of the drug is needed to give the same effect on the body/brain; e.g. Liver enzymes r stimulated to metabolize the drug faster and faster. There may be a strong genetic predisposition to addiction, some studies suggesting that 1 of 10 people will become dependent on alcohol or some ...Read more

What is risk of c diff if repeatedly treated with antibiotics? Also risk of antibiotic resistance?

What is risk of c diff if repeatedly treated with antibiotics? Also risk of antibiotic resistance?

Uncommon but real: This is an uncommon but real issue.Risk varies with the type/duration and intensity of antibiotic use (IV vs oral,etc.) Many centers do stool surveillance cultures to spot this in higher risk patients. Resistance is an everyday issue today which drives us to be selective & specific on antibiotic use.The risk of an individual having to deal with these is part of dealing with healthcare today ...Read more

What sort of problem is antibiotic resistance?

What sort of problem is antibiotic resistance?

Big problem: When an antibiotic is given, susceptible bacteria die but any bacteria that have the ability to survive the antibiotic survive and then multiply so the bacteria that are left, cannot be killed by that antibiotic. The bacteria that are left are thus resistant to that antibiotic. ...Read more

Which factors that lead to antibiotic resistance?

Which factors that lead to antibiotic resistance?

Acquired genes: Since the introduction of abx in usable quantities we have seen germs gradually change. They have dna like u do & can mutate over time.Some can reproduce in < 10 minutes & every generation can form a new resistant mutant, reg abx kill the old & the mutant lives on to create pbs.Every time someone takes abx it puts pressure on germs & a mutant may emerge. That's why we shouldn't take for viruses. ...Read more

What are the causes for the development of antibiotic resistance?

What are the causes for the development of antibiotic resistance?

Mutations: Just like humans, germs have dna that occasionally mutates. For some mutations it will lead to development of new cell wall structure or other features that alter the germ enough that a specific antibiotic no longer works to kill it. The more often an antibiotic is used in the general population, the more pressure exists to create a resistant strain. ...Read more

What organisms have antibiotic resistance?

Many: These little buggers evolve so fast! you've heard of the flesh eating bacteria? Some strains are deadly to the point of no current antibiotic works against them now. Sorry, not a good answer to your question. Please ignore this answer. ...Read more

How do bacteria become antibiotic resistance?

How do bacteria become antibiotic resistance?

They Adapt!: Antibiotic resistance is a type of drug resistance where the bacteria no longer are succeptible to the drug. This usually occurs when the microorganism mutates its dna to be able to "inactivate" the medication. This is a type of "natural selection" amoung the bacteria. This is a real threat to medicine today. The overuse of certain antibiotics has contributed to this. ...Read more

How does antibiotic resistance occur in hospitals?

How does antibiotic resistance occur in hospitals?

Antibiotic resistanc: Bacteria are able to adjust to exposure to the drugs that are designed to inhibit or kill them. It is a form of evolution. In a hospital, compared to other settings, the number of infections treated with antibiotics in very high. So the chances for these mututations is much higher. When patients become infected with bacteria from the hospital, it is often showing mulitple resistance. ...Read more

Urinary Tract Infection (Definition)

A urinary tract infection, also known as an UTI, may involve the kidney, ureter, bladder, or urethra. A common cause is an intestinal bacteria, E. coli. Common symptoms include a frequent urge to urinate, and pain or burning when urinating. Antibiotics are typically ...Read more

Antibiotic Resistance (Definition)

Antibiotic resistance is a symptom in which the bacteria infecting a person is resistant to some or all of the antibiotics available. Resistance means that the bacteria cannot be stopped or killed by the antibiotic, or that it takes a lot more antibiotics (big doses) ...Read more
