Staphylococcus Hominis ; Definition, Habitat, Characteristics, Uses, Pathogenicity, Resistance

Staphylococcus hominis is a Gram-positive, coagulase-negative bacterium that is part of the natural skin flora. Here are some key points about Staphylococcus hominis: Classification Domain: Bacteria Phylum: Bacillota Class: Bacilli Order: Caryophanales Family: Staphylococcaceae Genus: Staphylococcus Species: Staphylococcus hominis Characteristics Morphology: Gram-positive, spherical cells that form clusters. Habitat: Commonly found on human skin, particularly in areas with numerous apocrine glands, such as the axillae and pubic region2. Non-Motile: S. hominis is non-motile and non-spore-forming. Facultatively Anaerobic: It can grow in both aerobic and anaerobic conditions. Pathogenicity Commensal Organism: S. hominis is generally harmless and exists as a commensal on human skin. Opportunistic Pathogen: It can cause infections in individuals with weakened immune systems or those with implanted medical devices. Infections may include sepsis, urinary tract infections, and wound infections. Biofilm Formation: S. hominis can form biofilms on medical devices, which protect the bacteria from antibiotics and complicate treatment. Resistance Antibiotic Resistance: Some strains of S. hominis are resistant to multiple antibiotics, including penicillin, streptomycin, erythromycin, and tetracycline2. Diagnosis and Treatment Lab Diagnosis: Diagnosis involves sampling from the suspected infection site and identifying the bacterium through molecular and biochemical tests. Treatment: Treatment may include the use of antibiotics, but the presence of antibiotic-resistant strains can complicate management. Proper infection control measures are essential to prevent the spread of S. hominis in healthcare settings #Staphylococcus
