[20] S. aureus reproduces asexually by binary fission.

The results are determined by color changes, after 24 hours of incubation, and tests for polymyxin and novobiocin susceptibility [19] UZA (a rapid 4-hour method) This method is a two-step process. Step one consists of three tests measured after four hours incubation at 37 °C: acid production from D-trehalose, urease, and alkaline phosphatase.
MRSA is responsible for several difficult-to-treat infections in humans. It caused more than 100,000 deaths worldwide attributable to antimicrobial resistance in 2019. MRSA is any strain of S. aureus that has developed (through natural selection) or acquired (through horizontal gene transfer) a multiple drug resistance to beta-lactam antibiotics.
