Staphylococcus aureus is a gram-positive spherically shaped bacterium, a member of the Bacillota, and is a usual member of the microbiota of the body, frequently found in the upper respiratory tract and on the skin. It is often positive for catalase and nitrate reduction and is a facultative anaerobe, meaning that it can grow without oxygen. [1]
Staphylococcus scalded skin syndrome – Staphylococcus scalded skin syndrome is caused by toxins produced when a staph infection gets too severe. It is characterized by a fever, rash, and blisters. Methicillin-resistant Staphylococcus aureus (MRSA) – MRSA is one of the most common antibiotic-resistant strains of staph bacteria. It is more ...
Micrococcal nuclease (EC 3.1.31.1, S7 Nuclease, MNase, spleen endonuclease, thermonuclease, nuclease T, micrococcal endonuclease, nuclease T', staphylococcal nuclease, spleen phosphodiesterase, Staphylococcus aureus nuclease, Staphylococcus aureus nuclease B, ribonucleate (deoxynucleate) 3'-nucleotidohydrolase) is an endo-exonuclease that preferentially digests single-stranded nucleic acids.
The pathogen methicillin-resistant Staphylococcus aureus is a member of this family. The most famous species in this family is Staphylococcus aureus, usually found in the skin microbiota. Staphylococcus aureus is the pathogenic bacteria with the highest global mortality in 2019, with approximatively 1.1 million deaths. [3]
Staphylococcus species are facultative anaerobes (capable of growth both aerobically and anaerobically). [15] All species grow in the presence of bile salts. All strains of Staphylococcus aureus were once thought to be coagulase-positive, but this has since been disproven. [16] [17] [18] Growth can also occur in a 6.5% NaCl solution. [15]
S. aureus bacteria can live on the skin which is one of the primary modes of transmission. S. aureus can cause a range of illnesses from minor skin infections to Staphylococcus aureus food poisoning enteritis. Since humans are the primary source, cross-contamination is the most common way the microorganism is introduced into foods. Foods at ...
It is caused by Staphylococcus aureus, and Streptococcus pyogenes. [18] Erysipelas is an acute streptococcus bacterial infection [19] of the deeper skin layers that spreads via with lymphatic system. Cellulitis is a diffuse inflammation [20] of connective tissue with severe inflammation of dermal and subcutaneous layers of the skin.
The diagnosis of vancomycin-resistant Staphylococcus aureus (VRSA) is performed by performing susceptibility testing on a single S. aureus isolate to vancomycin. This is accomplished by first assessing the isolate's minimum inhibitory concentration (MIC) using standard laboratory methods, including disc diffusion, gradient strip diffusion, and automated antimicrobial susceptibility testing ...
