Staphylococcus species can be differentiated from other aerobic and facultative anaerobic, Gram-positive cocci by several simple tests. [15] Staphylococcus species are facultative anaerobes (capable of growth both aerobically and anaerobically). [15] All species grow in the presence of bile salts.
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 ...
Staphylococcus aureus (/ ˌ s t æ f ɪ l ə ˈ k ɒ k ə s ˈ ɔːr i ə s,-l oʊ-/, [16] [17] Greek σταφυλόκοκκος ' grape-cluster berry ', Latin aureus, ' golden ') is a facultative anaerobic, gram-positive coccal (round) bacterium also known as "golden staph" and "oro staphira". S. aureus is nonmotile and does not form spores. [18]
Staphylococcus pseudintermedius was first identified as a novel species in 2005 using 16S rRNA gene sequencing of the tRNA intergenic length polymorphisms of the AJ780976 gene loci. [15] [16] [17] Differing strains of S. pseudintermedius, LMG 22219 - LMG 22222, have been identified in various species: cat, horse, dog, and parrot, respectively. [15]
[43] [47] SCCmec is thought to have originated in the closely related Staphylococcus sciuri species and transferred horizontally to S. aureus. [48] Different SCCmec genotypes confer different microbiological characteristics, such as different antimicrobial resistance rates. [49] Different genotypes are also associated with different types of ...
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 hominis is a coagulase-negative member of the bacterial genus Staphylococcus, consisting of Gram-positive, spherical cells in clusters.It occurs very commonly as a harmless commensal on human and animal skin and is known for producing thioalcohol compounds that contribute to body odour.
SCCmec, or staphylococcal cassette chromosome mec, is a mobile genetic element of Staphylococcus bacterial species. This genetic sequence includes the mecA gene coding for resistance to the antibiotic methicillin and is the only known way for Staphylococcus strains to spread the gene in the wild by horizontal gene transfer.
