Staphylococcus aureus is an important cause of hospital acquired infection. Gram negative cocci Neisseria gonorrhoea needs raised carbon dioxide levels to be cultured, bacteria appears in pairs (diplococcic) Gram negative: Gram-negative bacteria are bacteria which do not turn purple in the Gram staining process used as a basic step in the identification of bacteria. Most bacteria can be divided into either Gram-positive or Gram-negative bacteria, reflecting key differences in the composition…

test on my unknown, I found that it was a gram negative organism. This prompted me to do some tests that are specifically for gram negative organisms. When I looked under the microscope I seen some rod shaped bacteria. So what is this organism and is it causing the reported cases of GI distress? The gram stain I did showed a pink organism which told me that it was gram negative. I then continued with some tests that were specifically for gram negative bacteria. I did an OF glucose test, a…

arrangements that were stained red. I determined that this bacterium was gram negative because of red color of the bacteria. The bacterium labeled 7B showed multiple single bacilli that were stained purple. I determined that this bacterium was gram positive because of the purple color of the bacteria. By performing the gram stain, I was able to divide my two bacterium into 1 gram positive bacterium, and 1 gram negative bacterium. I was now able to determine that bacterium 7A could only be one…

fact, 1 out of every 25 hospitalized patients becomes affected by an HAI. (4) There are several types of pathogens capable of causing healthcare acquired infections. Gram-negative bacteria are known for causing infections in the bloodstream, pneumonia, wound infections, surgical site infections, and even meningitis. Gram-negative bacteria are resistant to most antibiotics which is what makes them so difficult to treat.…

products (cheese , yoghurt etc..). In fact, they inhibit these microbes up to 5 orders of magnitude at refrigerator temperatures (6oC) without changing the quality of the food. The bacterial mixture is effective against some yeasts, molds, and gram-negative bacteria, but not other gram-positive bacteria. During the tests on the inhibition activities of Propionibacterium sp., cell-free supernatants containing the organic acid molecules that are products of fermentation were not as effective in…

called Gram-positive bacteria. On the other hand, the dye is washed away from bacteria with thinner cell walls, and these are considered Gram-negative. The latter do not become colorless, but pink when counterstained with safranin. Part 3: When to Apply Gram Staining Gram staining procedure is used to determine if bacteria are Gram-positive or Gram-negative. This is usually the first step in the process of identifying bacteria that are present in cultures. This procedure is important in giving a…

1.Introduction: Background/Aim. 1.1 Nature of the microorganism: Enterococcus faecalis was placed under group D streptococci because of similar lysis characters; Identified as Gram positive, non-motile, anaerobic fermentative, lactic acid bacteria; are commensal inhabitant of intestinal bacteria and opportunistic pathogens. They occur singly or in pairs or chains. 1.2 Economic importance: Enterococcus faecalis is also used as a probiotic for production of Mediterranean cheese and meat products…

Listeria monocytogenes is a gram-positive rod-shaped bacterium and facultative anaerobic that can grow under either anaerobic or aerobic conditions but do not form endospores. Among the six species of Listeria, only Listeria monocytogenes is the major human pathogen that causes disease in humans. It is a causative agent to cause listeriosis, a serious infection caused by ingesting the food contaminated with Listeria. The optimum temperature for growth is 30 to 37 degree Celsius, within this…

Bacterium Inoculums preparations for the MIC and MBC experiments From the previous isolated and identified MRSA and VRSA S. aureus isolates, four MRSA+VRSA and four MRSA+VSSA isolates were chosen for MIC and MBC experiments. With a sterile loop, a loopfull from each chosen isolate was inoculated from the BHI slant into MH broth then incubated with shaking at 37°C overnight for 24 hours. The concentrations of these suspensions were adjusted to be equal to the 0.5 McFarland standards by adding a…
