What is Stomatococcus?

What is Stomatococcus?

Rothia mucilaginosa (formerly Stomatococcus mucilaginosus) is a gram-positive aerobic coccus that was traditionally found as a cause of oral, cutaneous, and central nervous system infections in impaired hosts.

What is Staphylococcus aureus morphology?

Microscopic morphology. S. aureus cells are Gram-positive and appear in spherical shape. They are often in clusters resembling bunch of grapes when observed under light microscope after Gram staining. The name ‘Staphylococcus’ was derived from Greek, meaning bunch of grapes ( staphyle ) and berry ( kokkos ) [1].

Is Stomatococcus catalase positive?

Rothia mucilaginosa (formerly Stomatococcus mucilaginosus). mucilaginosa strains, members of normal oral flora, form cocci in clusters and display variable catalase reactions ranging from negative to weakly positive to strongly positive.

What is the classification of Staphylococcus?

BacilliStaphylococcus / ClassBacilli is a taxonomic class of bacteria that includes two orders, Bacillales and Lactobacillales, which contain several well-known pathogens such as Bacillus anthracis. Bacilli are almost exclusively gram-positive bacteria.
The name Bacillus, capitalized and italicized, refers to a specific genus of bacteria. Wikipedia

Where is Rothia Mucilaginosa found?

Rothia mucilaginosa, previously Stomatococcus mucilaginosus, is an aerobic, gram-positive coccus belonging to the family Micrococcaceae. It is found in the oropharynx and upper respiratory tract as part of the normal flora [1] and was first isolated from an endocarditis patient in 1978 [2].

What causes Rothia?

The most common sources of Rothia bloodstream infection were presumed gut translocation (n = 13, 52%), catheter-related infection (n = 8, 25%), and mucositis (n = 9, 36%). No source of bacteremia was identified for 5 (20%) of the patients.

Is Staph aureus coagulase positive or negative?

Classification. S aureus and S intermedius are coagulase positive. All other staphylococci are coagulase negative. They are salt tolerant and often hemolytic.

Are members of Micrococcaceae catalase-positive?

Microbiology and Ecology. The staphylococci are members of the family Micrococcaceae, which also includes Micrococcus, Stomatococcus, and Planococcus. These bacteria are catalase-positive, gram-positive cocci that divide in irregular clusters, producing a “grapelike cluster” appearance when viewed under the microscope.

What Staphylococcus looks like?

The symptoms of a staph infection depend on the type of infection: Skin infections can look like pimples or boils. They may be red, swollen, and painful. Sometimes there is pus or other drainage.
