What does gram negative on a serratia marcescens gram stain mean?
Bacteria are gram positive or gram negative. Serratia happens to be a gram negative bacteria. They appear pink on a gram stain. Gram positive bacteria stain to a purple color on a gram stain. We can classify and ID bacteria using their gram stain and shape. Some antibiotics only work on gram negative bacteria and some only work on gram positive bacteria. It helps a doctor know which antibiotic to use.
Is pneumonia gram postitive?
I assume you mean bacterial pneumonia, from there it is dependent on what type of bacteria is causing the pneumonia. For example Streptococcus pneumoniae is gram positive, but Klebsiella pneumoniae gram negative.On the whole though, bacterial pneumonia is more typically caused by gram positive bacteria.
What does a positive result mean?
+ UTI (urinary tract infection)
Can Gram-positive organism appear as Gram-negative?
Staphylococcus are Gram positive because, in Gram's test, the decolorizing agent (ETOH) cannot penetrate the thick cell walls, and the stain remains behind: hence Gram positive. I am not aware of a gram negative staph species and, considering the degree of mutation that would be needed to form such a strain, I do not believe that it's possible. I should add that a not-so-brief scan of the net showed me no Gram negative staph mentioned anywhere. So -- for now -- no. That said, let's see what the future holds.

What is S Acin in a urine culture report?
what does a report mean when is say 1,000-10,000 CFU/ml of Gram positive cocci and Gram negative bacilli. Is this a positive culture?
You are positive for gram negative bacilli?
I am gram-positive bacilli... what does this mean??
What does the medical term cocci mean?
Cocci means round.
What does 1000 to 10000 cfu ml gram positive flora mean?
it is the amount of bacteria in the culture....1000-900 colony forming units per ml

What are bacilli bacteria?
bacteria Indeed they are bacteria! The Gram stain is a common, inexpensive, and very useful test that Medical Technologists (laboratory workers in hospitals) do to help doctors diagnose and treat bacterial infections. The bacilli part simply means the shape of the bacteria. A bacillus is a rod-shaped bacteria - think of a tiny sausage! The other common shape is a "coccus" or "cocci" (cocci and bacilli mean there is more than one) which is a sphere - like a tiny grape. I won't go into the details of the test, but basically the specimen (whatever body fluid was submitted to the lab) is stained in a special way that typically shows one of two different results: Gram negative or Gram positive. Why does Gram positive or negative matter? First, it helps with deciding WHAT the bacteria is and second, it helps determine WHAT ANTIBIOTIC can be used to treat an infection with it. Gram positive bacteria have a very thick outer cell layer made of peptidoglycan which stains dark purple. Gram negative bacteria have different layers on the outside of their cells and the peptidoglycan layers are much thinner - so they stain pink. So a Gram positive bacillus is sausage/rod shaped that stains dark purple with a Gram stain test. Examples are: Clostridium, Bacillus, and Listeria, but there are MANY more!

What does gram mean In medical terms?
Gram in medical terms may refer to a unit of mass (e.g. give one gram of azithromycin in one dose to cure chlamydia), or could refer to a procedure for determining the identity of a bacterium through a specific gram-staining process (e.g. gonorrhea is a gram-positive diplococcus.)
