Gram Negative Bacteremia
High vaginal swab result: scanty leucocytes & gram positive cocci, numerous gram positive bacilli, moderate epithelial cells . Result shows infection?
Not likely: Bacteria are part of the contents of the vaginal barrel. When infection is present due to bacteria there are usually large numbers of leucocytes and few epithelial cells. All told, however, test results are not always accurate, and best to discuss this with the doctor who ordered this to begin with. ...Read more
Culture/Gram's stain: Depends upon whether these were from the culture or the stain of some clinical material, where the culture was obtained from, and why. This may be an entirely inconsequential result or possibly represent severe illness, but would need far more info to say. Discuss this with the doctor who cultured you. If this was from your tonsil it is probably Strep and you should have been treated. Get better. ...Read more
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
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
Urine Culture Results
50,000-100,000 CFU/mL Staphylococcus coagulase negative not S.saprophyticus
10,000-50,000 CFU/mL Multiple organisms
See below: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, the colony count, the dominant organism and multiple organism all suggest that this is not real urinary infection. The organisms are likely to be skin contaminants. ...Read more
Urine; moderate WBC, no nitrites, culture <50k multiple non-uropathogenic gram positive bacteria. No symptoms. Possible contamination? Antibiotics??
Contaminant: Infection is when pathogens (bacteria for example) invade your tissues. This almost always produces signs which include redness, swelling, warmth and pain. In the absence of symptoms this is a contaminant or a colonization of your urinary tract. Note: Do not test urine without a good reason.... ...Read more
Positive for fungal spores
gram stain:few gram negative bacilli in singles, few gram cocci in singles and moderate epithelial cells & pus cells noted ?
Vaginal swab result
direct smear: no trichomonas
gram stain : epithelial cells positive cocci and positive bacilli..Is it normal?
Urinary infection: Bacteria usually originate from the bowel, vagina, or skin as normal flora of the host. Gram-positive organisms can include staphylococcus saprophyticus (causative organism in 5% to 15% of utis) and enterococcus faecalis it means urinary infection related to gram positive organism. ...Read more
Sputum culture showed normal flora.gram stain showed mod.amt of gram positive and neg. bacilli and mod.amt of gram positive cocci.few wbc.concerns?
No.: From your description, it sounds like the diagnosis was normal flora present. The bacilli and cocci with few WBCs are just describing that. Normal flora is a mixed population like that described. When one has an infection, the causative organism will predominate and will likely be the only thing present. There will also usually be numerous WBCs as these are your cells that fight infection. ...Read more
Probably E Coli: There are many dozens of bacteria that can be lactose fermenting gram negative bacilli. This is just a classification scheme based on gram positive or negative; rod (bacillus) or cocci (ball); and what they grow on in a laboratory evaluation. Examples include e. Coli, klebsiella, enterobacter, citrobacter. ...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
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
