Doctors, what is the difference between bacillus cereus, bacillus subtilis, and bacillus licheniformis?

Different species: These are different species in the genus bacillus. Anthrax bacillus is also in the same genus. You may Google each term to learn about their characteristics. ...Read more

Morphology (Definition)

As used in pathology, this is the abnormal shapes and arrangements of organs, tissues, cells, and components of cells that enable the diagnosis of disease and help to understand its impact. Some diseases involve only abnormal function of normal-appearing parts and thus ...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 Meaning?

Urine Culture Results
50,000-100,000 CFU/mL Staphylococcus coagulase negative not S.saprophyticus
10,000-50,000 CFU/mL Multiple organisms
Meaning?

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

Hi Doc, had UTI test. Result: Epithelial cells 1-2/HPF, pus Cells 2-3/HPF, colony count 100,000 cfu/ml. Organism Isolated:Staphylococcus saprophyticus?

Possible UTI: The organism you described is a skin contaminant and is not considered a pathological bacteria it is not the bacteria that has given you a bladder infection. If you have pain on urination or pain around the belly you may have a bladder infection these values in your urine analysis are not diagnostic of a UTI. ...Read more

Psmear result, pus cell 6-8, epithelial cell ++, gram +vecocci++@+vebacili+, gram-vecocci, -vebacili nil, fungal hype@trichomonas nil, do  ihve to wory?

No worry : The primary purpose of pap smear is to detect cancer or pre-cancerous changes of the cervix. Nothing in your report suggests that. Gram positive and gram negative bacteria along with some fungus, epithelial cells, and leukocytes are all normal inhabitants of the vaginal flora. The presence of trichomonas (std) or hpv (std linked to cancer of cervix) would be abnormalities requiring treatment. ...Read more

Sputum?: This sounds like a grossly inadequate sputum specimen, or one which was actually primarily saliva. The organisms seen are all part of normal oral flora, and this specimen should be repeated with an induced sputum specimen if the clinical situation warrants. ...Read more

Sarcoidosis: The bacteria you mentioned all benign skin contaminant and not because most likely of the noncaseating granuloma. Noncaseating granuloma skin happening sarcoidosis a poorly understood reactive process which can lead to shortness of breath. Other causes include fungal agents and yeast infections. A biopsy would be important. ...Read more

Suggests contamination with urogenital or skin flora. >100,000 CFU/ml Lactobacillus species. 20,000 CFU/ml mixed gram positive flora. What's it mean?

Suggests contamination with urogenital or skin flora. 
>100,000 CFU/ml Lactobacillus species.
20,000 CFU/ml mixed gram positive flora. 
What's it mean?

Means contaminated: Urine specimen from the surrounding area around urethra (opening where the urine comes out from). You may want to repeat the test , if your doctor still wants that, get a clean catch specimen, which entails cleansing the area first, passing some urine, then obtain a midstream urine sample, follow the lab instructions for that, best wishes ...Read more

Pls interpret vagina gram stain reslt.Gm Stain (-),Polymorphonuclear-Moderate,Epi cells-Moderate,Gm(+)Cocci pairs-Few,Gm(+)bacili-Mod,Gm(-)bacili-rare?

Pls interpret vagina gram stain reslt.Gm Stain (-),Polymorphonuclear-Moderate,Epi cells-Moderate,Gm(+)Cocci pairs-Few,Gm(+)bacili-Mod,Gm(-)bacili-rare?

Probably normal: It's hard to give you a definitive answer without seeing it and knowing what was causing your diarrhea, but the vagina normally has bacteria present (all the Gm + and - categories) and some polymorphonuclear cells (neutrophils). The gram+ bacilli are most likely lactobacillus, the normal flora of the vagina.The epithelial cells are simply the lining of the vagina. ...Read more

Gram Stain Result	
Few Polys
Rare Gram negative rods

High vaginal swab result: scanty leucocytes & gram positive cocci, numerous gram positive bacilli, moderate epithelial cells . Result shows infection?

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
