    Gram-positive cocci are an interesting group of bacteria to study. Some common species include Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis, Streptococcus pyogenes, and Sarcina lutea. Gram-positive cocci have a gram positive cell wall, cocci morphology and many different styles of grouping. Some species have begun to exhibit a resistance to fluoroquinolone by the use of altering the drug binding site and the use of a membrane pump (Hooper 2002). Thanks to the resistance to this antibiotic, this opens the door to superinfections. Superinfections occur when an antibiotic eliminates competing bacteria and allows the mutant and resistant survivors to repopulate. Superinfections can be dangerous especially in immunocompromised…

    which concluded the genus of the gram positive is Streptococcus. Streptococcus ID introduced many different tests to further identify the gram positive species. One-fourth of the blood agar plate is to determine the hemolysis of the bacteria which is Alpha/Beta because of the partial to complete clearing of the red blood cells. Three-fourth of the plate was used in order to see the susceptibilities of the SXT and Bacitracin discs. There was no zone clearing for SXT which is resistant and 32 mm…

    My professor had suggested that instead of me continuing on ahead doing the catalase test she had recommended that I do a mannitol salt agar test or a Blood agar test for my final test, which would help determine between Streptococcus pneumoniae, Staphylococcus epidermidis. I decided to go along with the mannitol salt agar method and again with my inoculated loop I grabbed some of my unknown #15 and I had applied it to aseptic technique to the agar plate. While waiting for my results to appear,…

    When aseptically plated on the differential blood agar plate and compared to controls, Unknown 15 was identified as non-hemolytic (gamma hemolysis). Growth best resembled the control Staphylococcus epidermidis which is non-hemolytic, indicating that Unknown 15 did not produce hemolysins to lyse RBCs into hemoglobin (1). Therefore, the alpha and beta hemolytic genus Streptococcus was eliminated (5). There was not an inconsistency in this result but, rather, a variability. The species that Unknown…

    The Bile Esculin test was performed on a Bile Esculin Agar slant by inoculating the slant in a zig-zag pattern and was stabbed using an inoculating needle. The slant was then incubated at 37°C for 48 hours. After incubation, the slant was taken out and observed for any change. The Bile Esculin Agar used in the test was used as a selective and differential medium. The bile that was in the medium was selective for streptococci and enterococci and inhibited the growth of Gram-positive staphylococci…
