Antibiotics/ Antiviral or Antifungals Paper
Staphylococcus aureus is a Gram-positive bacterium. It causes multiple infections including Staphylococcal scalded skin syndrome (SSSS). It appears purple from gram staining due to the presence of a thick peptidoglycan which absorbs the stain. The thick layer also causes antibiotic resistance. Antibacterial activity focuses on destroying the peptidoglycan. Antibiotics/ Antiviral or Antifungals Paper
The article is about staphylococcus diseases caused by Staphylococcus aureus strains of bacteria. According to Bass (2016), these pathogens strains produce digestive enzymes and toxins which influence the invasive potential and virulence. This results in the development of specific clinical diseases. The most common illnesses include exfoliative skin disorders, Staphylococcal scalded skin syndrome (SSSS), staphylococcal enterocolitis, staphylococcal food poisoning and toxic shock syndrome (Bass, 2016). In general, the author reviews the specific staphylococcal toxins mediated diseases.
Staphylococcus aureus is a round-shaped Gram-positive bacterium from the class Bacilli and Bacteria domain. It is a prokaryote meaning that it is single celled and lack a nuclear membrane as well as other cellular organelles. Notably, it belongs to the Staphylococcaceae family of facultative anaerobes and genus staphylococcus which appear spherical under a microscope and form in grape-like clusters.
Cellular/ structural characteristics
Susceptibility to antibiotics/ antiviral or antifungals
The hosts for S. aureus are both the phagocytic and nonphagocytic cells. In Staphylococcal scalded skin syndrome, the bacterium invades the epithelia cells of humans and releases toxins that cause skin blistering and peeling. They feed on N-acetylglucosamine, sucrose, glucose, mannose, beta-glucosides, lactose, galactose, and mannitol and hence are chemoorganotrophic heterotrophic. They grow in mesophilic conditions with moderate temperature. They reproduce rapidly through binary fission yielding yellow colonies. The life cycle involves five stages namely attachment, multiplication, exodus, maturation and dispersal.
