;Caption: Human oral bacterium Stomatococcus mucilaginosus. This genus is formerly known as Micrococcus mucilaginosus or Staphylococcus salivarius. It is a coccoid-shaped, Gram-positive, catalase variable bacterium and is considered part of the normal human oral flora and upper respiratory tract flora. It has recently been described as a human pathogen causing infection. The mode of entry for this bacterium is usually a venous catheter but sometimes an oral lesion. Although believed to be an organism of low virulence, S. mucilaginosus has been reported to be an opportunistic pathogen, the most common clinical presentation being septicemia, endocarditis, and catheter-related sepsis.
