  2. Aerococcus urinae - Wikipedia

    en.wikipedia.org/wiki/Aerococcus_urinae

    Aerococcus urinae is a member of the bacterial genus Aerococcus.The bacterium is a Gram-positive, catalase-negative coccus growing in clusters. Isolates of this genus were originally isolated in 1953 from samples collected in the air and dust of occupied rooms and were distinguished by their tetrad cellular arrangements. [2]

  3. Staphylococcus saprophyticus - Wikipedia

    en.wikipedia.org/wiki/Staphylococcus_saprophyticus

    Staphylococcus saprophyticus was not recognized as a cause of urinary tract infections until the early 1970s, more than 10 years after its original demonstration in urine specimens. Prior to this, the presence of coagulase-negative staphylococci (CoNS) in urine specimens was dismissed as contamination. [citation needed]

  4. Gram stain - Wikipedia

    en.wikipedia.org/wiki/Gram_stain

    Gram stain (Gram staining or Gram's method), is a method of staining used to classify bacterial species into two large groups: gram-positive bacteria and gram-negative bacteria. It may also be used to diagnose a fungal infection. [1] The name comes from the Danish bacteriologist Hans Christian Gram, who developed the technique in 1884. [2]

  5. Gram-positive bacteria - Wikipedia

    en.wikipedia.org/wiki/Gram-positive_bacteria

    Violet-stained gram-positive cocci and pink-stained gram-negative bacilli. In bacteriology, gram-positive bacteria are bacteria that give a positive result in the Gram stain test, which is traditionally used to quickly classify bacteria into two broad categories according to their type of cell wall.

  6. Staphylococcus pseudintermedius - Wikipedia

    en.wikipedia.org/wiki/Staphylococcus...

    Staphylococci spp. are a genus of gram positive cocci of 0.5 - 1 μm diameter. [citation needed] Staphylococcus pseudintermedius is a non-motile and non-spore forming, facultatively anaerobic bacterium. [citation needed] It appears primarily as grape-like clusters morphologically, but can also be seen as individual or paired cocci.

  7. Macrococcus - Wikipedia

    en.wikipedia.org/wiki/Macrococcus

    Members of the genus Macrococcus are Gram-positive, nonmotile, non-spore-forming cocci that are coagulase negative and catalase positive. They can be distinguished phenotypically from most staphylococci on the basis of their cellular morphology (they are 2.5 – 4.0 times larger in diameter compared to Staphylococcus aureus) and their positive cytochrome c oxidase reaction.

  8. Anaerococcus - Wikipedia

    en.wikipedia.org/wiki/Anaerococcus

    These bacteria are Gram-positive and strictly anaerobic. [2] [3] [4] The genus Anaerococcus was proposed in 2001. [2] [4] Its genome was sequenced in August 2009. The genus Anaerococcus is one of six genera classified within the group GPAC (Gram-Positive Anaerobic Cocci). [5]

  9. Peptostreptococcus - Wikipedia

    en.wikipedia.org/wiki/Peptostreptococcus

    Anaerobic gram-positive cocci such as Peptostreptococcus are the second most frequently recovered anaerobes and account for approximately one quarter of anaerobic isolates found. Most often anaerobic gram-positive cocci are usually recovered mixed in with other anaerobic or aerobic bacteria from various infections at different sites of the ...
