Question 1

what is gram positive rod negative in a blood culture test?

Accepted Answer

See below: Gram positive rods are a class of bacteria.  The majority of bacteria involved in disease are either gram positive or negative and come in rod, cocci (grapes), or spirals.  If the culture says it is gpr negative, then that means no gram positive rods were found.  However, it may say other forms were found, including gnr.

Question 2

how long does it take to develop gram positive cocci in clusters in blood, i get blood drawn every week?

Accepted Answer

Should never happen: You should never have gram positive cocci in clusters in your blood.  In fact you should never have any bacteria detectable in your bloodstream.

Question 3

my results from culture sputum: gram stain: moderate red blood cell, many gram positive cocci in gram stain, many gram positive bacilli, many negative bacilli in gram stain . what that mean?

Accepted Answer

Nothing: Sounds like the “sputum” was contaminated with fluid from your mouth.  What the report describes are the bacteria normally in your mouth - and is meaningless.

Why did you get a sputum culture?  Check in with the doctor who ordered it

Question 4

my gram stain test results study result narrative penis wound 4/27/2022 18:33:11 pdt component results gram stain result your value stains/preparations many white blood cells moderate gram positive cocci few gram negative rods is it bad?

Accepted Answer

: This result doesn't mean very much one way or the other. It suggests possible infection, but it could also just be a normally healing wound. Presumably a culture also was done. Discuss with your doctor. Good luck.

Question 5

what does it mean if somebody says their blood culture tested positive for cocci in the blood stream?

Accepted Answer

Sepsis: it means they may. Have a infection most likely staphloccus which is a bacteria found on skin . Common in patients  who are admitted in a hospital or who have had surgical procedures , it may  even be a contaminant which means false positive

Question 6

i have gram positive flora in urine, leukcoytes, blood and bacteria all +1. should i be on antibotic, is this considered a uti.

Accepted Answer

No: You dont mention if you have any symptoms while urinating, this could be a contaminated sample.

i am in hospital w/a "gram+ bacillus" sepsis..6/8 blood culture bottles are +. caused by a dirty cut then severe cellulitis. i have heart vegetation from it they say. also on cellcept. can you educate me on whats the significance of heart vegetation?

Accepted Answer

Endocarditis. : What you describe is endocarditis. The vegetations harbor the bacteria that are identified when blood cultures are obtained.  Sepsis, heart failure as well as "septic emboli" are potential complications   6 weeks of IV antibiotics followed by repeat blood cultures and follow up echocardiogram to insure treatment was adequate.

Question 8

would a blood culture be positive if i had meningitis?

Accepted Answer

Not always: It depends on how bad the meningitis is, but it helps narrow down the antibiotis if the blood cultures were positive.

Question 9

how much bacteria do you need in a blood culture for it to be positive?

Accepted Answer

What kind more imp: Bacterial normally present on the skin sometimes contaminate blood drawn for culture and constitute a false positive.  It is the type of organism cultured that is more important than how many.

Question 10

rod positive blood culture after pneumonia. ed said maybe false positive did more blood cultures . sent me home. temp is 99. scared. what to do?

Accepted Answer

Probably all is OK: Bacilli ("rods") in blood culture usually are contaminants, i.e. normal skin bacteria, especially "Gram positive" rods. Such bacteria rarely cause pneumonia. Therefore, the ED probably did the right thing by reassuring you, repeating the blood culture, and sending you home -- assuming, of course, you were not seriously ill based on symptoms, fever,  etc. Double check w/ your dotor.
