Gram negative rod blood infection after c-section; where it came from why it happened; do I have organ damage; they treated it 5 days after c-section.

Infectious diseases: Blood stream infections by "gram negative rods" are often what we now call "healthcare associated infections" or hai's. Seen in hospitalized patients with indwelling urinary catheters or central venous lines. Patients who are chronically ill or immunosurpressed and those hospitalized for extended periods of time are more susceptible to these infections. ...Read more

Infection (Definition)

Infections are invasions of some other organism (fungus, bacteria, parasite) or viruses into places where they do not belong. For instance, we have normal gut bacteria that live within us without causing problems; however, when those penetrate the bowel wall and enter the bloodstream, ...Read more

My daughter 4 had a fever--urine results state she has small amount of hemoglobian and Lactose positive gram negative bacilli? Urinary tract infection

My daughter 4 had a fever--urine results state she has small amount of hemoglobian and Lactose positive gram negative bacilli? Urinary tract infection

Incomplete data: To properly label a 4 yo as a UTI you would need a clean catch or catheterized urine, and growth of >50,000 colonies/unit on a properly plated culture media. Just having pee with a germ in it doesn't qualify. The common squat pee collected in some offices is part vaginal wash out and will contain skin contaminant germs. This might or might not be a UTI. ...Read more

Gram negative bacilli found in urine? Does this mean a urinary tract infection? Doc didn't even mention it.I am urinating more frequently but no pain

GNB: A urine microscopy showing GNB may not be infection and can be a contaminant. Suggest a clean catch urine be done and a urine culture of needed but done right. Sounds like you have no symptoms and this may not be an issue. ...Read more

What's a rare gram negative rods mean? It was taken vaginally via gram stain.

This could be normal: Bacteria are classified, broadly, as being gram-negative or gram-positive (retains violet dye color after staining--gram stain-- a lab slide with specimen on it). And either being rod (cylindrical/barrel shaped) or spherical (cocci) when viewed under a microscope. Gram negative rods are very common in the genital tract, and it sounds like you don't have too many. I say probably normal. Good wishes ...Read more

See below: I assume you are referring to the gram stain of some type of secretion or wound.
This means that there are many gram negative bacilli such as e. Coli, klebsiella, proteus, pseudomonas etc seen on examining the gram stained specimen under the microscope. The specific gram neg bacillus should be identified on the culture results. ...Read more

What is meant by gram positive bacteria and gram negative bacteria?

What is meant by gram positive bacteria and gram negative bacteria?

Staining technique: Gram positive organisms have a high amount of material in their cell walls which retain gentian violet (a purple stain) on slides looked at under the microscope. Gram negative organisms have the gentian violet washed out when subjected to acid-alcohol and then they are restained with a red stain which renders them red under the microscope. It is one way of loosely classifying bacteria. ...Read more

Doctors, what is the difference between gram positive cocci & gram negative bacilli?

Gram stain: The gram stain has been used for a long time to classify bacteria according to the chemistry of their cell walls (and hence whether they are gram positive or negative.) Cell shape and growth characteristic are also useful in grouping bacteria until more full speciation information becomes available. The gram stain is fast, reasonably reproducible by trained personnel and the groupings useful 4 rx ...Read more

Got tested for UTI my results say this : GRAM NEGATIVE BACILLI UNDER 10 M CFU/L what does that mean?

Got tested for UTI my results say this : GRAM NEGATIVE BACILLI UNDER 10 M CFU/L what does that mean?

Probable UTI: The lab uses slightly atypical numbers. The cut-off for a high bacterial count in most UTIs is 100,000 per mL, which is the same as 10 million per L. However, with only a single gram negative organism, even lower numbers usually are significant, so this result indicates probable UTI that needs treatment. Discuss with your doctor. (FYI, CFU = colony forming units, i.e. no. of bacteria.) ...Read more

Can gram negative folliculitus be cured? How long is it safe to take ampicillin for this? Likelihood of ampicillin curing GNF? Thanks!

Folliculitis: Can be cured with antibiotics, but it can recur. It is usually due to gram positive bacteria (Staphlococci), however, if you are certain that this one is due to gram negative bacteria (by culture), then ampicillin is not the best antibiotic. The physician needs to select an antibiotic that works well for gram negative organisms ...Read more
