    First of all, its S. pseudintermedius ¬†(just rectifying you and not being rude or anything! ūüôā )

    S. pseudintermedius can be biochemically misidentified as S. aureus (be cautious!!).  It  has been  recently identified as new coagulase positive species of S. intermedius group. Few phenotyphic  tests such as PYR test (+), mannitol fermentation test (weakly and delayed), clumping factor activity test (-),  ONPG test(+),  VP or acetoin test (+),  acriflavine sensitivity test (S ). Novobiocin sensitivity test (S)  can be considered.  Genotyphic tests targeting mec A , nuc  genes of S. aureus and tuf gene of Staphylococcus genus can also be performed.

    I have attached a link for  the  comparative phenotypic characteristics .

    I hope its helpful enough.

    This might help you for basic understanding and visualisation. However, do rely for standard links.

  • Level 1 Asked on October 26, 2015 in Bacteriology.

    Actinomyces is gram positive, strict anaerobic or facultative anaerobe , and peculiar characteristic is that they form fungus like branched network of hyphae (so the name actinomyces or “ray fungus” ). It is to note that Actinomyces ¬†and ¬†other genera of ¬†family Actinomycetaceae are thought to be transition between bacteria and fungus.

    Neisseria  is gram negative (so you can basically distinguish it from Actinomyces on gram stain reaction), aerobic, diplococci bacteria.

    Hope your curiosity is answered!

    the means  and costs of treatment, mode of transmission (how number of people/animals gets affected by virus in short time) for viral infections make virus more challenging than any other microbes otherwise, the pain and complications associated with any infections  carry equal weight.
