It grows at temperature ranging from 15’C-45’C by aerobic respiration or fermentation that produced lactic acids. It reproduced asexually through binary fission and has the capacity to survive from weeks to months on dry environmental conditions.

Staphylococcus aureus is considered as potential pathogens and responsible for various tissue infections including skin and mucosal barriers. It can spread via pus from infected wound as well as from towels, clothing, sheets and equipment used by infected individuals.

Staphylococcus aureus infections can spread via contact with infected wound, skin contact and pus with an infected individual by generating hyaluronidase that destroys tissue and contact with objects such as towels, sheets, clothing or athletic equipment used by an infected person. It is also associated in prosthetic joints that risk staphylococcal endocarditis, septic arthritis and pneumonia.
