Why might an infection by Gram-negative bacteria be more difficult to treat than a Gram-positive bacterial ?

---

help me pleaseee. im having probs with these bacteria questions. can someone please help me out? i appreciated it alot. The question is:
Why might an infection by Gram-negative bacteria be more difficult to treat than a Gram-positive bacterial infection?
Because the two layers of the cell wall in gram negative cells protect the cytoplasm better than the one layer in gram positive cells.

What does gram positive and negative stain do inside a bacterial cell?

---

It doesn't do anything inside a bacterial cell. These stains are for determining what type of bacteria they are (gram positive or negative). The reason why they are classified as such is because gram positive and gram negative bacteria have different cell walls. Knowing the structure of their cell walls will help determine which antibiotics should be used in order to destroy them.  (+ info)

What are some genus names of gram positive bacteria?

---

I need as many genus names for gram positive bacteria as you guys can think of.
I need to come up with a genus name for my bacterial unknown and I don't know to many different genuses. Let me know some names so I can research and figure out what mine is.
To narrow it down, it is a rod and I believe it is non-endospore forming.
Thanks for your help.

Oh and they dont have to be medically significant, but I thought this would be a good area to post my question.
WOW. I wish i could help but I got lost early in the question. Hope you get some help.  (+ info)

how will knowledge of Gram positive bacteria and their infections/diseases help in a healthcare careerr?

---

Nurse, doctors
Knowledge of what pathogen is causing infection aids in specifying a cure, often an antibiotic. Broad spectrum antibiotics are prescribed first until a culture can be incubated. Once this is done, the lab personnel can determine what antibiotic this specific organism is sensitive to. This done, antibiotic treatment can be targeted to the specific pathogen, thus preventing tolerances to the broad spectrum antiinfective class of medicine.  (+ info)

What is a Gram Positive Infection?

---

I am 28 weeks pregnant and had a routine Ob appointment on Monday July 30 with a routine urine test. The nurse called today and said there was an infection in my urine called a Gram Positive Infection. Last week suffered from a slight head cold that left me feeling congested with no other serious symptoms.

I searched the internet for information on Gram positive infections but found very little that proided an answer in layman's terms. What is a Gram Positive Infection and what are the effects on a fetus at 28 weeks gestation?

When I questioned the nurse she just stated that it was a bacterial infection.

Thank
Gram positive and gram negative and just ways of classifying bacteria. If you ever take Microbiology you will do this yourself in the lab, it's kind of fun.

Two common bacteria that may have found their way into your urine are staph aureus (common in the mouth) and e. coli (found in feces). However, when tested the cell wall of gram-positive bacteria (such as staph aureus) will retain gentian violent and show up as colored pinkish purple. Gram-negative bacteria, such as E. coli do not.

If you have a gram positive infection, most likely it's a staph infection, do you have a bladder infection? Did they do a vaginal swab at this appt? If so they may have been testing for GBS or group beta strep, a bacteria that lives in some women's vaginas. Normally, this is benign, but the dr. needs to know so you can be treated during labor with antibiotics. Otherwise, the baby is at risk for sepsis or infection.  (+ info)

I keep getting bacterial infections and keep going back to the doctor for medicine. Any suggestions?

---

I have recurring bacterial infections. I feel like the medicine I am being given to treat the infection is not strong enough and doesn't completely fight off the bacterial. Has anyone been in this situation before and does anyone know anything that can be done?
Well, generally I can say that if the treatment and diagnosis is right there should be no problem. Do you take antibiotics on right dosages and frequency? If antibacterials are suddenly stopped or minimized, drug resistance may occur thereby decreasing it's effectiveness. If that should happen, a "stronger" type of antibiotic is given OR a combination of drugs to increase potency.  (+ info)

How to Bacterial intoxications differ from Bacterial infections of the digestive system?

---

Bacterial intoxications differ from bacterial infections of the digestive system in that intoxications :
a. are accompanied by fever
b. are more severe
c. are transmitted via water
d. are treated with antibiotics
e. have a shorter incubation time
E. The toxin acts immediately.  (+ info)

What can be some possible causes for reoccurring bacterial infections?

---

I have had reoccurring bacterial infections for years now. Just recently my monthly period went away, and my vaginal area was hurting/irritatable. Now I have this discharge, with a slight order and I know that is a sign of some type of bacterial/yeast infection. It seems to come back like 3-4 months after I get the anitbotics.

Does anyone have the answer?
You have an imbalance somewhere. After the antibiotics are over, you need to take probiotics (acidophilus). Health food stores have them. This puts back the friendly bacteria in your body. Cut out the sugary food in your diet, it can spur the growth of yeast infections, they love sugar. You might want to drink natural cranberry juice as well. Good luck.  (+ info)

How would you explain the importance of avoiding bacterial infections to a person with leukemia?

---

How would you explain to a patient with leukemia, who has a greatly elevated white blood count, the importance of avoiding bacterial infections?
I agree with the others that they should have a low white blood cell count.

However, I would tell them its a matter of life or death, literally. During my leukemia treatment I got an infection while I was neutropenic. I went in to septic shock, was on life support for about two and a half weeks and very nearly almost died.  (+ info)

why are bacterial infections in the bone difficult to treat with antibiotics?

---

Hip replacement surgeries as well as other bone replacement or bone pinning operations are notorious as a source of bacterial infections that are intractable to antibiotic treatment. In two or three sentences, speculate on why this is the case.
Think about it, and you'll have your answer.

How is an antibiotic going to reach the site of an infection? Through the blood. What kind of blood supply is there to a bone, such as the femoral head (a common site of hip relacement surgeries). What if the single blood supply is interrupted because of a clean break through the femoral head? In a case like that, very little blood is reaching the area, and tissue death can result (avascular necrosis) and nothing can help tissue once it has died. An extreme example, but in each case it would be all about adequate blood supply to the area of a bone infection, or the lack thereof.

Best wishes.  (+ info)
