what is the difference between Actinomycis and Niesseria
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.
