How do you identify a micrococcus?
DIAGNOSIS. Micrococci are catalase-positive, oxidase-positive, strictly aerobic Gram-positive cocci that grow in clusters. On sheep blood agar they form cream-colored to yellow colonies. Resistance to mupirocin and staphylolysin, and susceptibility to bacitracin and lysozyme differentiate them from the staphylococci.
What causes micrococcus?
Micrococcus species, members of the family Micrococcaceae, are usually regarded as contaminants from skin and mucous membranes. Nevertheless they have been documented to be causative organisms in cases of bacteremia, endocarditis, ventriculitis, peritonitis, pneumonia, endophthalmitis, keratolysis and septic arthritis.
What is the difference between Staphylococcus and Staphylococcus aureus?
The genus Staphylococcus currently contains 35 species. Staphylococci are Gram-positive cocci that grow in clumps, are catalase test positive and coagulase test positive (Staph. aureus) or negative (coagulase-negative staphylococci). ... Streptococci are Gram-positive cocci that grow in pairs or chains.
What test is used to differentiate staphylococcus from Streptococcus species?
CATALASE TEST:
The Catalase test differentiates between groups of microorganisms on the basis of catalase production. This test is consistently positive for staphylococci and negative for streptococci. Catalase is an enzyme that splits hydrogen peroxide into water and oxygen.
Where is micrococcus found?
Micrococcus strains commonly are found in a large variety of terrestrial and aquatic ecosystems, including soil, fresh and marine water, sand, and vegetation. The skin of warm-blooded animals, including humans, is a main reservoir for Micrococcus strains, which frequently contaminate foods of animal origin.
Where is Micrococcus luteus found in the human body?
An obligate aerobe, M. luteus is found in soil, dust, water and air, and as part of the normal microbiota of the mammalian skin. The bacterium also colonizes the human mouth, mucosae, oropharynx and upper respiratory tract. It was discovered by Sir Alexander Fleming before he discovered penicillin in 1928.
What is the shape of Micrococcus luteus?
M. luteus was first known as Micrococcus lysodeikticus and was discovered by Alexander Fleming in 1928. Its name stands for: microscopic (micro), of spherical shape (coccus), and yellow (luteus).
Which type of cocci are called micrococcus?
Micrococcus, genus of spherical bacteria in the family Micrococcaceae that is widely disseminated in nature. Micrococci are microbiologically characterized as gram-positive cocci, 0.5 to 3.5 μm (micrometres; 1 μm = 10-6 metre) in diameter. Micrococcus luteus bacteria on blood agar.
Is Micrococcus luteus Halotolerant?
The results from this research revealed that Micrococcus luteus, Staphylococcus aureus, and Staphylococcus lentus are halotolerant organisms.
What infections do staphylococcus and streptococcus cause?
In adults, it can cause urinary tract infections, blood infections, skin infections and pneumonia. Antibiotics are used to treat strep infections.
Where is Staphylococcus aureus found?
Staphylococcus aureus or “staph” is a type of bacteria found on human skin, in the nose, armpit, groin, and other areas. While these germs don't always cause harm, they can make you sick under the right circumstances.
Where are staphylococcus and streptococcus bacteria found?
Staphylococci are found on the skin. Streptococci are found in the respiratory tract. No hemolysis or beta hemolysis.
