Staphylococcus includes at least 44 species. Of these, nine have two subspecies, one has three subspecies, and one has four subspecies. [5] Many species cannot cause disease and reside normally on the skin and mucous membranes of humans and other animals. Staphylococcus species have been found to be nectar-inhabiting microbes. [6]
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 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 hominis is normally found on human skin and is usually harmless, but can sometimes cause infections in people with abnormally weak immune systems. Most, if not all, strains are susceptible to penicillin, erythromycin, and novobiocin, but a divergent strain, S. hominis subsp. novobiosepticus (SHN), was isolated between 1989 and ...
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]
The species and diversity of the microorganisms may be related to the various levels of hormones during pregnancy. Vaginal flora can be transmitted to babies during birth. Vaginal dysbiosis can lead to vaginal infections like bacterial vaginosis which makes one relatively susceptible to sexually transmitted diseases.
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]
The SCCmec found in methicillin-resistant Staphylococcus aureus likely originated in coagulase-negative staphylococcal species and was acquired by S. aureus. [13] Staphylococcal strains isolated from pig farms were found to carry several different types of SCCmec, suggesting that they may serve as a reservoir of these elements. [14]
