Gram Positive Cocci In Clusters In Blood Culture
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. ...Read more
How long does it take to develop gram positive cocci in clusters in blood, I get blood drawn every week?
What does it mean if somebody says their blood culture tested positive for cocci in the blood stream?
I have gram positive flora in urine, leukcoytes, blood and bacteria all +1. Should I be on antibotic, is this considered a uti.
No: You don't mention if you have any symptoms while urinating, this could be a contaminated sample. ...Read more
Got typhidot +ve, then gave sample for blood culture. It showed gram -ve e.Coli lactose fermenting rods. Had night fevers & now extreme weakness.
Sepsis: You have a very severe infection called sepsis that needs to be treated immediately. Discuss this with your doctor. ...Read more
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 what's the significance of heart vegetation?
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. ...Read more
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. ...Read more
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?
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. ...Read more
Hi doctor, my brother blood first report and final report got Negative result. My question is blood culture result should come positive or negative?
No should on testing: There is no should. The results are either yes or no. When a patient us severely ill, or has sepsis, treatment often starts before culture results are known. It appears there is much more to your story and this app cannot answer anything specific about the situation you are facing. Your concerns should be addressed by the professional responsible for this care there at the hospital. ...Read more
How fast can infection show up in a blood culture? (I was called back in about 12 hrs to come back in due to positive result)
Under 12h, obviously: Obviously it can show up in under 12 hours; they wouldn't have called you back if the test were not definitely positive. The fast result could suggest a particularly dangerous infection: virulent bacteria often are detected rapidly, and it also may mean large numbers of bacteria in the blood. This could be very serious; get back to the doctor IMMEDIATELY. Good luck! ...Read more
Urinalysis negative but culture positive for e.Coli (100, 000 cfu ml) w/cath draw. Blood culture negative. Fever of 104. Why was urinalysis negative?
Urinalysis: Sounds like you may have had upper urinary tract infection without spillage of inflammatory cells into the renal calyx, so that although the bacteria showed up the inflammatory cells did not. The other alternative is that this was somehow a contaminated specimen and the e. Coli were not from the urinary tract. ...Read more
At the hospital, I had three blood cultures that contained gram-negative rods. What does this mean?
Multiple ways: A few organisms may show up in blood culture due to transient bacteremia in an otherwise normal person. This may be due passing hard stool. More commonly e coli cause infections in various sites, most commonly, urinary tract, and then invade the blood stream and cause septicemia/sepsis with meaningful growth in blood culture. ...Read more
Context!: In many cases, yes- but it depends on the situation. If one was to have a single positive blood culture set out of 2 or 3 sets, and the patient is feeling better without interventions, it may be because of a contamination. However, if someone with terrible teeth has a prosthetic device, clinical symptoms, and labs consistent with an infection, then it may actually be a real infection. ...Read more
Can't keep them out: These little creatures live on the skin, and it's not possible to sterilize the venipuncture site perfectly. Usually they mean nothing. One pitfall -- anthrax bacilli mimic corynebacteria if the technician isn't paying VERY close attention. But you'd also be frightfully sick. Hoping the workup continues productive, and best wishes. ...Read more
Yes: Vertebral osteomyelitis is usually acquired after surgery on the spine or by hematogenous or blood stream spread. The bacteria are only in the bloodstream intermittently so blood cultures can be positive or sterile. Patients with more continuous bacteremia often have underlying heart valve infections, endocarditis. ...Read more
Yeast: The answer is "it depends." Some common yeast forms can grow in standard blood culture media, butothers may require more specialized growth media. The site or suspected origin might give a clue as to whether this is likely to happen. Also, yeast sometimes require longer to grow than other bacteria, so holding the culture longer may also be indicated if a blood-born yeast is suspected. ...Read more
Depends: Routine blood cultures are usually read at 24 and 48 hours and then again at 7 days and 14 days depending upon the organisms that are growing. Newer "blood culture" results using a variety of methods including dna testing or radioactive metabolite detection can often be read much sooner- in hours. ...Read more
1-5 days: It can be as soon as one day but labs will usually incubate and monitor the cultures for up to 5 days to make sure nothing is growing. ...Read more
