Gram Negative Rods 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

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.

Patients who are chronically ill or immunosurpressed and those hospitalized for extended periods of time are more susceptible to these infections. ...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?

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
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.

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
Recent blood infection, 2nd blood culture neg. After wk. Of meds, sed rate/crp down, cbc ok, no fevers. Normal to feel achy/tired for a while still?
You betcha!: Blood infections are very serious. Any serious disease, inc. pneumonia takes a toll on your body. It may take you a month or so, &sometimes longer, to get up to full speed again.

Being happy & content helps healing. ...Read more
CT result-Thorax extensive mediastinal lympopathy with central caseating, TB lymphopathy to consider skin, blood culture negative it is TB disease?
Caseating granulomas: This sounds like tuberculosis, but may conceivably be systemic fungal infection like Histoplasmosis, rarely lymphoma or sarcoidosis. In India this is probably TB and either should be treated empirically or wait for the results of the biopsied lymph nodes. Sounds as if your doctor is very astute and would heed their advice. Best wishes. ...Read more
What can cause elevated WBC count and fever of 103.9 when chest xray, nose swab, blood culture and ua come back negative in a 4 yr old boy?
Common with virus: Any fever elevation of that amount can double the white count as the normal stress response of the body. It sounds like they have looked for the treatable causes & come up without one. The next step would be watchful waiting to see how the process evolved. Many times you won't know what happened until the process runs its course. There are far to many viruses to have a simple test to prove a cause ...Read more
Cbc shows lympho 18.4% and esr of 42.have low grade fever sonce 2 weeks with fatigue and body pain. Neg blood culture typhoid ebv and tsh. Which virus?
More info needed: The lymphocyte count is normal or close to it (depending to some extent on what your total white blood cell count is). However, 42 is quite a high ESR. The causes you list are possible, but there probably are a hundred other health conditions that could do this. You haven't provided nearly enough information to even guess. Keep working with your doctor. Good luck! ...Read more
Can you think of any reason why blood cultures would come back with negative results within 2 hours even though antibiotics not commenced until hours after the results have come back.
Unclear question: If the blood culture results were reported within 2 hours, then it could not have bee culture, as that takes at least 24 hours, longer depending on the type of organism and microbial load. It was probably some other test like CRP, not blood culture, that was reported within two hours of blood collection. It may help to talk to the pathologist in-charge of the laboratory. ...Read more
If a patient has suspected sepsis and urgent blood cultures are attempted then, approximately, how quickly could it be established that the results are negative.
Blood cultures done for swollen fingers/neck pain. 2 cultures drawn same site. Results " growth of coagulase negative staph" dr. Says contaminated? ?
Second opinion: Any thing is possible. If done by your family physician or specialist ask for another specimen to culture. If truly contaminated then procedure was not done with sterile technique. ...Read more
I asked a q and told fits endocarditis (murmur, fatigue&splinter haemorrhages).Blood cultures&echo negative. Cud it still be endo or maybe lupus instead?
There some organisms that are difficult to culture that cause endocarditis such as hacek organisms. I agree with the recommendation for a tee if you have not had one
however; lupus can present with libman-sack endocardititis but that should be seen on an echo or transesophageal echo. You may need to see both a rheumatologist and cardiologist if you are not already. ...Read more
I have had fever for about 3weeks w/ muscle/joint pain. I have swollen lymph nodes in my neck also. Blood cultures returned negative. Any suggestions?
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
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
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
