Staphylococcus Aureus

Staphylococcus aureus

**Staphylococcus aureus** is a bacterium that is one of the most common pathogens found in the environment. It can cause a variety of illnesses in humans, including skin and soft tissue infections, as well as respiratory and gastrointestinal infections. Staphylococcus aureus can also lead to nosocomial infection, which is life-threatening. In this article we will look at the bacterium Staphylococcus aureus, its characteristics and possible consequences for human health.

Staphylococcus aureus: General information Staphylococcus aureus is a facultative anaerobe that can grow in the presence or absence of oxygen. It multiplies, forming up to twenty forms with the properties of a bacterium or a primitive fungus. Of these, the most pathogenic are spherical cocci, golden in color - they are part of the gram-positive mobile group (alpha-hemolytic coagulase-negative). There are also several types of staphylococcus, which differ in the methods of growth and reproduction, in the spectrum of sensitivity to antibiotics, in the objects of contamination of the body and in other characteristics. Dirty hands and surfaces colonized by Staphylococcus aureus bacteria. They usually form as clusters of microcolonies. Microcolonies of staphylococci are usually round in shape, but can be chain-shaped, rod-shaped, or complex clusters. Oval or round micrococci are associated with rough surfaces of micropoints (eg, the surface of the skin groove) or with projections. Oblong, long or elongated cells grow mainly on wavy surfaces. The processes of such cells can be directed upward or to the side. Concave shapes form on feathers or chains of staphylococcal cells. They are usually associated with convex surfaces of porous materials. Some forms most closely resemble fungal blastulas. In addition, the shape of a microcolony can change when exposed to oxygen. As the oxygen content in the cells drops, the staphylococcal colony mutates into aerobic forms. Aerobic colonies can also decrease in size (Mölleryouagitche), increase in size (Dunleavy 2003) and change shape. If an infectious staphylococcal mass formed after infection
